WATER RESOURCES
- Rainfall
The origin of freshwater is rainfall, and rainfall varies with geographical location and climate. Geography and climate affect the amount of rainfall and the season when it rains. As a result of geography and climate, rainfall in certain places can be concentrated for several months or can be spread throughout the year.
In subtropical areas, such as Africa Savannah and the Monsun Asia area, rainfall is usually concentrated in one season.
Rainfall intensity
With less intense rainfall, there will be a little attack and more infiltration.
With more intense rainfall, there will be more run-off and less infiltration. If the amount of rainfall is less than the soil can absorb, it will all infiltrate; There will be no runoff.
What happens to the water that infiltrates into the ground?
Water that infiltrates the ground can reach a certain extent absorbed by land, depending on the thickness and composition. The more clay is contained in the ground, the more water can be held. But Clay doesn't absorb water quickly. Remember: Water enters clay slowly, but clay land can accommodate more water than sandy soil. Water enters sandy soil quickly, but sandy soil holds more water than clay land. Water that has been absorbed by land will be partly used by plants and partially evaporated on the ground. Water that has not been absorbed by land seeps into the soil. How fast and how deeply depends on the composition, structure and coating the soil layer and the rock formation structure below. Depending on this, thus, the depth in which water is found on the ground will vary from some surface water which has not been absorbed by the soil called ground water. Levels where ground water is found on the ground called the water table. When the water table is high enough to ride above the surface in low areas, swamps, lakes or flows formed by many metres. When rock formations under the layers of porous soil, water can soak into the rock, it can permeate severe when rock formations under the waterproof layer, water cannot seep into a great depth. This will accumulate on the rock and easier to reach. Do and maybe it's hard to reach.
2.RIVERS
River water is a surface water source and part of the water cycle. It can be used for households, irrigation, industrial processing or for energy production.
The economic benefits of rivers and lakes are:
- Give water for irrigation.
- Providing water for drinking.
- Help develope Hyde strength.
- Help develope Hyde strength.
- AIDS in tourism and recreation.
How does river get water ?
Water generally collects in rivers due to rainfall through drainage basins of surface runoff and other sources such as refill groundwater, springs and water release stored on natural ice and as far as snow (e.g, from Glaciers).
Why is it important to save the river?
The river is really very important: for fresh drinking water, for community livelihoods and for nature. Unfortunately, they are still threatened. We must be committed to recovering fresh water biodiversity, restoring natural river flow and cleaning water contaminated for people and nature to develop.
How we protect our rivers ?
The river is the lifeline of all types of civilization. ... we need to protect our river. Most rivers have been converted into waterways. They are covered with so much dirt so they cannot be considered a fresh water source again.
What do rivers provide ?
The river provides important benefits such as drinking water, irrigation, and more. As a house for fish, plants, and wildlife, the river is very important for the survival of many species - including ours.
How can we save river water ?
Every year, the river shrinks as a community of driving water that is not replaced by precipitation, which has been reduced due to climate change. Fortunately, you can do your part to save the river by reducing your water use, using river friendly products, involved, and urging others to make changes.
What are three main functions of river ?
3.Lakes Water
Water on the lake comes from rain, snow, ice melting, flow, and land water seepage. Most lakes contain fresh water. All lakes are open or closed. If the water leaves the lake by the river or other outlets, it is said to be open. All freshwater lakes are open.
Why the lake is a water source?
Lake supplied with water with rainfall which falls directly on the surface of the lake, with water runoff from adjacent soil and a small flow, or with ground water which seeps through the ground to the lowest point which is a lake.
What is the use of lake water ?
The lake functions as a large waste sink for solid and liquid waste from households, land area, industry, livestock production and poultry and fisheries activities.
What are advantages of lakes ?
The advantages of lakes and lakes of rivers and lakes make a great contribution to humans, because they give us our source of life, water. For this, the benefits of benefiting from rivers and lakes cannot be numbered. Lake and river help:
- develop hydroelectric power.
- They provide water supply for irrigation purposes.
- Give fresh water to drink.
- Industry and factories use river water and lakes for their functions.
- Water to develop fisheries.
- They increase the natural beauty of the environment, thus helping to develop tourism and provide recreational facilities.
- The function of funds can alleviate the impact of floods and droughts in certain fields by storing large amounts of water in the flood time and releasing it during deficiency in drought.
What is the importance of Lakes ?
The importance of lake lake is generally formed as a consequence of tectonic or glacial activities in typical regions. The lake is also formed because the river is winding or even by human activities. The lake is quite important for civilization, there are abundant reasons to direct them out, this owes the reason when the lake is a water resource, and water is a certain source to continue life on this planet. Well, we will show the importance of the lake. Also, what is provided below are some famous lakes that both get their interests.
- To regulate the flow of river water for the purpose of storing water during the dry season maintaining and balancing ecosystems to produce hydroelectric power.
- lakes also help in filling groundwater.
- This increases and helps in preserving biodiversity area, where the lake is located.
- Lake also helped the economy, by increasing the economic activity of the area.
- When the lake is always regarded as a recreational place, therefore they support tourism.
- While in India there are various types of freshwater lake and salted water lakes.
- Wuler's famous Lake in Jammu and Kashmir is the largest freshwater lake in India.
- Meanwhile, other freshwater lake is Dal in Jammu and Kashmir, Lake Bhimtal, and Initial Lake located in Astrakhan.
- Lake Roller is also located in Andhra Preside.
- This Koestler Lake was officially classified as a wildlife asylum so that this lake functions as a source of entertainment.
- Lake Senambarhar in Rajasthan is one of the biggest salt lakes that produce salt.
- Thus, this makes Rajasthan third largest salt producers in this country. Brackish water is a mixture of salt water and fresh water.
- Lake Chilika is located in Orissa is the largest brackish water lake in India.
- Andrivers used for irrigation purposes.
- We are very dependent on the river for fresh drinking water.
- River water is also used to produce water power.
- Thus, we see the river water is too widely used.
- This affects the quality of these river water.
- Government actions and policies are launched to treat river water, hence to overcome this, the local community can use lake water as a substitute for river water that is more or less functioning the same.
- Lake water is also served with fresh water. It can also be a source of irrigation and also become a hydroelectric resource.
