Journey of a River

Given: A map showing the course of the river Godavari.

Answer: The Godavari river flows through the following states:
1. Maharashtra (where it originates near Trimbakeshwar, Nashik)
2. Telangana
3. Andhra Pradesh (where it meets the Bay of Bengal)

It also passes through parts of Chhattisgarh and Odisha in its basin area.

Given: A map showing features along the Godavari river.

Dam: The Godavari river has several dams built along it. A well-known dam is the Dowleswaram Barrage (also called Sir Arthur Cotton Barrage) in Andhra Pradesh. Another important dam is the Sriram Sagar Dam in Telangana.

Wildlife Sanctuary: The Papikonda Wildlife Sanctuary (also known as Papikonda National Park) is located along the Godavari river in Andhra Pradesh. The Kolleru Wildlife Sanctuary is also associated with the Godavari delta region.

Answer: Dam — Sriram Sagar Dam (Telangana); Wildlife Sanctuary — Papikonda Wildlife Sanctuary (Andhra Pradesh).

Given: A map showing tributaries of the Godavari.

Answer: Several small rivers (tributaries) join the Godavari during its journey. These include:
1. Pravara (joins in Maharashtra)
2. Manjira (joins in Telangana)
3. Pranhita (formed by the union of Wainganga, Wardha and Penganga rivers)
4. Indravati (joins from Chhattisgarh/Odisha side)
5. Sabari (joins in the lower course)

These tributaries add to the volume of water in the Godavari as it flows towards the Bay of Bengal.

Given: Information and images about life along the Godavari river.

Concept: Rivers support human life in multiple ways — for basic needs, livelihood, and agriculture.

Three ways people depend on the Godavari:
1. Drinking water: People living in villages and towns along the Godavari use its water for drinking and daily household needs.
2. Agriculture/Irrigation: Farmers use the river's water to irrigate their fields and grow crops like rice, sugarcane, and cotton.
3. Fishing: Many communities depend on fishing in the Godavari for their food and livelihood.

*(Other valid answers: transportation by boats, religious/cultural ceremonies, generating electricity through dams.)*

Given: Images and text describing life along the Godavari.

Answer: People near the Godavari are engaged in the following occupations:
1. Farming/Agriculture — growing crops using river water for irrigation.
2. Fishing — catching fish from the river for food and sale.
3. Boat-making and boating — transporting goods and people across the river.
4. Ecotourism — guiding tourists to enjoy the natural beauty of the river and its surroundings.
5. Weaving and handicrafts — some communities along the river are known for traditional crafts.
6. Trade and commerce — selling fish, crops, and other goods at markets near the river.

Given: Images showing farmland along the Godavari river.

Answer: The following crops are commonly seen growing near the Godavari river:
1. Rice (Paddy) — The Godavari delta is one of the most fertile rice-growing regions in India.
2. Sugarcane — Grown in the upper and middle course regions.
3. Cotton — Grown in parts of Maharashtra and Telangana along the river.
4. Tobacco — Grown in the delta region of Andhra Pradesh.
5. Vegetables and pulses — Also grown in smaller quantities along the riverbanks.

Note: This is a personal/local observation question. A sample answer is provided below.

Sample Answer:
In our region, crops like wheat, rice, mustard, and vegetables are commonly grown.

The water for irrigation comes from:
- Canals connected to nearby rivers or dams.
- Tube wells and bore wells that draw groundwater.
- Rainwater during the monsoon season.
- Ponds and tanks in some villages.

*(Students should fill in the name of crops and water sources specific to their own state or region.)*

Given: The text explains that dams block the flow of rivers and create reservoirs, which can cause displacement of people and animals.

Problems that arise after a dam is built:

| Problem | Explanation |
|---|---|
| 1. Displacement of people | Villages and towns near the reservoir get submerged; people lose their homes and have to move elsewhere. |
| 2. Loss of forests and wildlife | Forests and animal habitats get flooded, causing animals to lose their homes. |
| 3. Change in river flow | The natural flow of the river is blocked, which affects fish migration and the ecology downstream. |
| 4. Loss of fertile land | Agricultural land near the river gets submerged under the reservoir. |
| 5. Earthquakes | Large reservoirs can sometimes cause small earthquakes due to the weight of water. |

Solutions:
1. Proper rehabilitation — People displaced by dams should be given new homes, land, and compensation.
2. Wildlife corridors — Safe passages should be created for animals to move to new habitats.
3. Environmental impact assessment — Before building a dam, a thorough study of its effects on nature and people should be done.
4. Minimum water flow — A minimum amount of water (environmental flow) should always be released downstream to keep the river healthy.
5. Community involvement — Local people should be consulted and involved in decisions about dam construction.

Conclusion: While dams are important for water storage and electricity, they must be built carefully, keeping in mind the needs of people, animals, and the environment.

Given: The text discusses how waste and plastic pollute rivers.

Answer: When we litter plastic wrappers and bags carelessly, they travel through the following path:

1. Plastic thrown on roads and open areas is carried by wind and rainwater into drains and gutters.
2. From drains, it flows into small streams and canals.
3. Eventually, it reaches rivers, lakes, and ponds.
4. From rivers, plastic waste is carried all the way to the sea and oceans.

Harm caused:
- Fish, turtles, and birds may swallow plastic thinking it is food, which can kill them.
- Plastic blocks the sunlight from reaching underwater plants.
- Plastic breaks into tiny pieces called microplastics, which enter the food chain and can harm humans too.
- Plastic clogs drains, causing flooding during rains.

Conclusion: Plastic litter that we throw carelessly ultimately ends up in our water bodies, causing serious harm to aquatic life and human health.

Note: This is a personal observation question. A sample answer is provided.

Sample Answer:

Cleaners used at home:
- Soaps and shampoos (readymade, containing chemicals like sulphates and parabens)
- Floor cleaners / phenyl (chemical-based)
- Dishwashing liquid (contains synthetic detergents)
- Some homes also use natural alternatives like shikakai, reetha (soapnut), neem, and ash for cleaning.

Where does the dirty water go?
1. The water mixed with soaps and cleaners goes down the drain.
2. In cities, it enters the sewage system and ideally reaches a sewage treatment plant (STP) where it is cleaned before being released.
3. However, in many places, this dirty water flows directly into rivers, ponds, or the ground without treatment.
4. This pollutes the water bodies and harms aquatic animals and plants.
5. Chemicals in these cleaners can also seep into the groundwater, making it unsafe for drinking.

Conclusion: Using natural, eco-friendly cleaners reduces the amount of harmful chemicals that enter our water bodies.

Given: We are asked to think about common waste items and their impact on water bodies.

List of common waste items and their harm:

| Waste Item | Harm to River/Pond |
|---|---|
| 1. Plastic bags and wrappers | Animals and fish may swallow them and die; they block sunlight and oxygen in water. |
| 2. Food waste (leftover food) | Rots in water, reduces oxygen levels, causes bad smell, and promotes growth of harmful bacteria. |
| 3. Paper | Decomposes and reduces oxygen in water; in large amounts, it can clog waterways. |
| 4. Glass pieces | Can injure fish, animals, and people who wade in the water. |
| 5. Chemical/battery waste | Releases toxic substances that poison fish, plants, and make water unsafe for drinking. |
| 6. Old medicines | Chemicals from medicines dissolve in water and harm aquatic life and human health. |
| 7. Cloth and rags | Block the flow of water; animals can get entangled in them. |

Conclusion: Every item we throw carelessly can cause serious damage to water bodies. We must always dispose of waste responsibly — in proper bins, and support recycling and composting.

Given: Two glasses of water — one with sugar, one with cooking oil.

Observation:
- The glass with sugar appears clear — the sugar dissolves completely in water and cannot be seen.
- The glass with cooking oil appears cloudy or separated — the oil does not mix with water; it floats on top or forms droplets.

Which one appears clear? The glass with sugar appears clear.

Conclusion from experiment: Some substances dissolve in water (are soluble) and some do not (are insoluble). Even when water looks clean, it may contain dissolved harmful substances that we cannot see.

---

Things that DISSOLVE in water (Soluble):
1. Sugar
2. Salt
3. Vinegar
4. Lemon juice
5. Some medicines
6. Chemical fertilisers
7. Soap (partially)

Things that DO NOT dissolve in water (Insoluble):
1. Cooking oil
2. Sand
3. Plastic
4. Wax
5. Chalk powder
6. Petrol/diesel
7. Mud (mostly)

Given: Two images — one showing a river with clean water, and another showing a river surface covered by a 'green blanket' of plants.

Which river looks healthy?
The river with clean, clear water looks healthy.

Why?
- It has clear water that allows sunlight to reach underwater plants and animals.
- Fish and other aquatic creatures can breathe and move freely.
- The water is safe for people and animals to drink.
- It supports a balanced ecosystem with plants, fish, birds, and insects.

How do so many plants grow in water?
When fertilisers used in farming get washed into the river by rain, they act as nutrients (food) for water plants and algae. These plants grow very rapidly because of the extra nutrients available to them. This process is called eutrophication.

What happens when too many plants grow in a river?
1. The plants cover the surface of the river like a 'green blanket', blocking sunlight from reaching deeper water.
2. Underwater plants cannot make food (photosynthesis stops), so they die.
3. As plants die and decompose, they use up the oxygen in the water.
4. Fish and other aquatic animals cannot breathe and begin to die.
5. The water becomes unsafe for drinking and smells bad.
6. The river slowly loses all its life — it gets 'choked'.

Conclusion: Excess fertilisers washing into rivers cause overgrowth of plants, which destroys the river's ecosystem. Farmers should use fertilisers carefully and in the right amounts to prevent this.

Given: The chapter discusses pollution of rivers and the need to keep them clean.

Three things I can do to protect water bodies near me:

1. Stop littering: I will never throw plastic, wrappers, or any garbage near rivers, ponds, or lakes. I will always use dustbins and encourage others to do the same.

2. Avoid using harmful chemicals: I will encourage my family to use natural, eco-friendly soaps, shampoos, and cleaners so that less harmful chemicals flow into water bodies through drains.

3. Participate in clean-up drives: I will join or organise cleanliness drives near local water bodies to remove plastic and other waste, and spread awareness in my community about keeping rivers and ponds clean.

*(Other valid answers: plant trees near riverbanks to prevent soil erosion; report illegal dumping of waste into rivers; save water to reduce the burden on rivers and reservoirs.)*

Given: A table of flood problems and things they affect.

Concept: Floods cause widespread damage affecting shelter, health, food, transport, and daily life.

Matching:

| Flood Problem | What it Affects |
|---|---|
| (i) Dirty water | (b) Safe drinking, (f) People's health |
| (ii) Broken roads | (d) Travel and transport |
| (iii) Lost crops | (g) Food supply |
| (iv) No electricity | (e) Lights, fans and phones |
| (v) Spread of diseases | (f) People's health, (b) Safe drinking |
| (vi) Damaged homes | (a) Shelter for people |
| (vii) Schools shut | (c) Learning |

Explanation:
- Dirty water makes drinking water unsafe and spreads diseases.
- Broken roads stop people from travelling and transporting goods.
- Lost crops reduce the food supply for people.
- No electricity affects lights, fans, phones, and other appliances.
- Spread of diseases directly harms people's health.
- Damaged homes leave people without shelter.
- Schools shut means children cannot learn.

Given: The chapter asks us to imagine a day without water.

Answer:
If there was no water in my home for an entire day, I would face many difficulties. Here is what I would do:

1. For drinking: I would use stored bottled water or go to a neighbour's house or a community water point to get drinking water.
2. For cooking: I would try to cook food that requires less water, or eat dry foods like bread, fruits, and biscuits.
3. For bathing: I would use wet wipes or skip bathing for that day.
4. For toilets: I would try to use as little water as possible, or use a public toilet.
5. For cleaning: I would postpone washing clothes and dishes until water is available.

Reflection: This experience would make me realise how precious water is and how important it is to never waste it.

Given: The chapter asks us to think about a week without water.

Answer:
A week without water would be a very serious crisis. Here is what I would do:

1. For drinking: I would go to the nearest river, well, or community water tanker. I would boil or purify the water before drinking it.
2. For bathing: I would bathe very minimally using very little water, or use dry shampoo and wet wipes.
3. For cooking: I would cook simple meals that need very little water. I might rely on packaged or dry food.
4. For cleaning: Washing clothes and mopping floors would have to wait. I would reuse dishes as much as possible.
5. Where to find water: I would go to the nearest river, pond, community hand pump, or wait for a government water tanker.

Reflection: A week without water shows us that water is the most essential resource for life. This is why we must conserve water every day and never waste it.

Note: This is a research-based personal question. A sample answer for a student from Maharashtra is given below. Students should fill in details for their own state.

Sample Answer (Maharashtra):

The major rivers that flow through Maharashtra are the Godavari, Krishna, Tapi (Tapti), Bhima, and Wardha.

(a) What are they used for?
- Drinking water for cities and villages.
- Irrigation for crops like sugarcane, cotton, jowar, and wheat.
- Hydroelectric power generation through dams.
- Fishing — many communities depend on river fish.
- Transportation — boats are used in some areas.
- Religious purposes — rivers like Godavari are considered sacred.

(b) Are there any dams on them?
Yes, there are many dams:
- Jayakwadi Dam on the Godavari river.
- Koyna Dam on the Koyna river (tributary of Krishna) — one of the largest dams in Maharashtra.
- Ujani Dam on the Bhima river.
- Hathnur Dam on the Tapi river.

*(Students should research and write about rivers and dams in their own state.)*

Note: This is an activity-based question requiring family interaction. A sample answer is provided.

Sample Answer:

My grandmother told me about the festival of Nag Panchami celebrated near our local river. People go to the river, offer prayers, and release small clay idols into the water as a mark of respect to nature.

She also told me about Chhath Puja, where people stand in the river at sunrise and sunset to offer prayers to the Sun God. The river is considered sacred, and people clean its banks before the festival.

Another story she shared was about how, when she was young, the river near our village was so clean that people would drink directly from it and children would swim in it freely.

*(Students should share the actual story or festival told by their own family members.)*

Note: This is a personal interview-based question. A sample answer is provided.

Sample Answer (based on a conversation with a grandparent):

(a) Condition of rivers when they were a child:
- The river water was clean and clear.
- People could drink directly from the river without any treatment.
- The river was full of fish, turtles, and birds.
- Children used to swim and play in the river safely.
- The riverbanks were lined with trees and green vegetation.
- There was no plastic or garbage near the river.

(b) What has changed since then:
- The river is now polluted with plastic, sewage, and industrial waste.
- The water is no longer safe to drink directly.
- Many fish and birds have disappeared.
- The river has become narrower due to encroachments on its banks.
- During summers, the river sometimes dries up completely, which never happened before.
- Factories and cities have grown along the riverbanks, increasing pollution.

Reflection: This comparison shows us how much damage has been done to our rivers in just a few decades, and why we must act now to protect them.

Given: The chapter discusses the importance of rivers for human civilisation.

Why people built houses and cities near rivers in the past:
1. Water supply: Rivers provided fresh water for drinking, cooking, and bathing.
2. Agriculture: River water was used to irrigate fields and grow food.
3. Transportation: Rivers served as natural highways for boats carrying goods and people.
4. Fertile soil: Riverbanks had rich, fertile soil (alluvial soil) ideal for farming.
5. Food (fishing): Rivers provided fish as an important source of food.
6. Trade and commerce: Cities on rivers became important centres of trade.
7. Protection: Rivers sometimes acted as natural barriers against enemies.

*This is why great ancient civilisations like the Indus Valley (Indus river), Egyptian (Nile), and Mesopotamian (Tigris-Euphrates) civilisations all grew near rivers.*

Are rivers still important today in the same way?
Yes, rivers are still very important today, and in some new ways too:
- Rivers still provide drinking water to millions of people.
- They are used for irrigation to grow food for a growing population.
- Hydroelectric dams on rivers generate electricity for homes and industries.
- Rivers support industries and factories that need large amounts of water.
- They are important for tourism and recreation.
- Rivers maintain ecological balance by supporting forests, wildlife, and biodiversity.

Conclusion: Rivers were the foundation of human civilisation in the past and remain equally — if not more — important today.

Given: This is a creative thinking question about river conservation.

My Rule:

"No one shall dump any waste — plastic, sewage, industrial chemicals, or garbage — into any river, pond, or water body. Anyone found doing so shall be fined and required to participate in a river clean-up drive."

Reason for this rule:
The biggest threat to rivers today is pollution from waste dumping. If we can stop waste from entering rivers, the water will become cleaner, fish and birds will return, and the water will be safe for people to use.

How it can be enforced:
- CCTV cameras near riverbanks.
- Community volunteers to watch and report violations.
- Regular inspections of factories near rivers.
- Awareness campaigns in schools and communities.

*(Students may suggest their own creative rules — all valid answers are acceptable.)*

Given: This is a reflective personal question about water conservation.

Sample Answer:

Once, I left the tap running while brushing my teeth. I did not turn it off until I was done, which wasted several litres of water.

What I could have done differently:
- I should have turned off the tap while brushing and only turned it on to rinse.
- I could have used a mug of water instead of letting the tap run.
- By doing this, I could have saved at least 5–10 litres of water in just one brushing session.

Other examples of water wastage and solutions:

| Water Wasted | Better Alternative |
|---|---|
| Long showers | Take shorter showers or use a bucket |
| Watering plants with a hose | Use a watering can with just enough water |
| Washing car with running water | Use a bucket and mug |
| Leaking taps | Get them repaired immediately |

Conclusion: Every drop of water we save today ensures that there is enough water for tomorrow.

Given: This is a design-based creative question.

Simple Water Filter Design:

Materials needed:
1. A plastic bottle (cut in half)
2. Gravel / small stones
3. Sand (coarse and fine)
4. Charcoal (from burnt wood)
5. Cotton or cloth
6. A container to collect filtered water

How to assemble:
1. Take the top half of the plastic bottle and turn it upside down (like a funnel).
2. Place a layer of cotton or cloth at the bottom (the neck of the bottle) to hold everything in place.
3. Add a layer of fine sand on top of the cotton.
4. Add a layer of charcoal on top of the sand.
5. Add a layer of coarse sand on top of the charcoal.
6. Add a layer of gravel/small stones at the top.
7. Place this filter over a clean container.
8. Pour dirty water through the top and collect the filtered water below.

Why each material is used:
- Gravel: Removes large particles like leaves, mud, and debris.
- Coarse sand: Removes smaller particles and dirt.
- Charcoal: Absorbs bad smell, colour, and some chemicals (acts as a natural purifier).
- Fine sand: Filters out very fine particles.
- Cotton/cloth: Acts as the final barrier to catch any remaining fine particles.

Important Note: This filter removes visible dirt and some impurities, but the water must still be boiled before drinking to kill germs and bacteria.

Conclusion: This simple filter shows how natural materials can be used to clean water, and helps us understand the importance of water purification.

Given: This is an imaginative city-planning question related to rivers.

My Plan for a New City Near a River:

---
(a) Steps to keep the river clean:
1. No dumping rule: Strictly ban throwing garbage, sewage, or industrial waste into the river. Heavy fines for violations.
2. Sewage treatment plants (STPs): Build modern STPs to treat all household and industrial wastewater before it is released into the river.
3. Green buffer zone: Plant trees and grass along the riverbanks to act as a natural filter and prevent soil erosion.
4. Eco-friendly industries: Only allow factories that follow strict pollution control norms near the river.
5. Community awareness: Educate citizens about river conservation through schools, posters, and events.
6. Regular clean-up drives: Organise monthly clean-up events involving citizens, students, and local government.

---
(b) Steps to prevent floods during heavy rains:
1. No construction on floodplains: Keep the natural floodplain of the river free from buildings so that excess water has space to spread.
2. Wetlands and lakes: Preserve and create wetlands near the city to absorb excess rainwater like a sponge.
3. Rainwater harvesting: Build systems to collect rainwater on rooftops and in underground tanks to reduce runoff.
4. Proper drainage system: Design wide, well-maintained drains so that rainwater flows away quickly without flooding roads.
5. Early warning system: Install flood sensors in the river and set up an alert system to warn citizens in advance.
6. Plant more trees: Trees absorb rainwater and reduce the speed of water runoff into the river.

---
(c) Steps to ensure enough water even during summers:
1. Rainwater harvesting: Collect and store rainwater during monsoon for use in summer.
2. Reservoirs and check dams: Build small check dams and reservoirs to store river water during the rainy season.
3. Water recycling: Treat and reuse wastewater for gardening, cleaning roads, and industrial use.
4. Groundwater recharge: Create recharge pits and ponds to allow rainwater to seep into the ground and replenish groundwater.
5. Water conservation education: Teach all citizens to use water wisely — fix leaks, take shorter showers, and avoid wastage.
6. Drip irrigation: Encourage farmers to use drip irrigation to use less water for crops.

Conclusion: A well-planned city can live in harmony with a river — using its water wisely, keeping it clean, and being prepared for both floods and droughts.
