What are the characteristics of surface water?

What are the characteristics of surface water?

Properties of surface water include temperature, saltiness (called salinity), turbidity, and levels of dissolved nutrients, such as oxygen and carbon dioxide.

What is difference between surface water and groundwater?

Surface water is the water that is available on land in the form of rivers, ocean, seas, lakes and ponds. Groundwater is the underground water that seeps into the soil and is located in large aquifers under the ground.

What is the difference between surface water resources and groundwater resource?

Hint: Both surface and groundwater are resources or reservoirs of water that we can use to sustain our life on Earth as we know it….

They can be directly used for different purposes like irrigation, cleaning etc They need to be pumped out of the ground.

What is the relationship between groundwater and surface water?

Surface-water/groundwater interactions include the exchange of water, and the chemicals that may be present in the water, which can lead to issues with water supply and water quality. Groundwater can be a major contributor to streams, lakes, and wetlands while surface water can contribute recharge to groundwater.

Why is groundwater and surface water important?

Groundwater, which is in aquifers below the surface of the Earth, is one of the Nation’s most important natural resources. It often takes more work and costs more to access groundwater as opposed to surface water, but where there is little water on the land surface, groundwater can supply the water needs of people.

What are the advantages of groundwater over surface water?

The water gets filtered while percolating through sand & stones. Therefore groundwater remains pure and clean. Since bore well is closed, no risk of getting contaminated. Since it is closed no danger of children or animals falling into it.

What are benefits of groundwater?

Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. Groundwater helps grow our food. 64% of groundwater is used for irrigation to grow crops. Groundwater is an important component in many industrial processes.

What are the advantages of surface water?


  • Easy to abstract water by direct pumping.
  • Water can be treated after use and put back into a river.
  • Dams and reservoirs can be used for hydroelectric power.
  • Reservoirs can be used for recreation.

What is an example of surface water?

Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks. The ocean, despite being saltwater, is also considered surface water. While surface water can seep underground to become groundwater, groundwater can resurface on land to replenish surface water.

What are the main sources of surface water?

Surface water originates mostly from rainfall and is a mixture of surface run-off and ground water. It includes larges rivers, ponds and lakes, and the small upland streams which may originate from springs and collect the run-off from the watersheds.

What are the different sources of surface water?

A. Surface or Direct Sources of Water:

  • Streams: Rainwater infiltrates into the soil and subsequently joins the ground water storage.
  • Lakes: Rainwater in excess of all sorts of losses runs off the surface of the earth.
  • Reservoirs:
  • Open Wells:
  • Tube Wells:
  • Artesian Wells:
  • Infiltration Gallery:

What is surface and ground water?

In general: Groundwater is located underground in large aquifers and must be pumped out of the ground after drilling a deep well. Surface water is found in lakes, rivers and streams and is drawn into the public water supply by an intake. Groundwater is water contained in or by a subsurface layer of soil or rock.

What are the advantages of withdrawing groundwater?

The advantages of withdrawing groundwater include water for drinking and irrigation; availability and locality; low cost, no evaporation losses; and it is renewable. Disadvantages include aquifer depletion from over pumping, subsidence, pollution, saltwater intrusion, and reduced water flow.

What are the two major advantages of underground water storage?

What are the Advantages of Water Stored in the Ground?

  • It does not evaporate.
  • It recharges wells near the area.
  • It provides moisture to the vegetation.
  • It does not provide breeding grounds for mosquitos , like stagnant water in lakes and ponds.
  • It is relatively protected from contamination by animal and human waste.
  • It benefits the local population.

What is the most easily polluted groundwater reservoir?

water-table aquifers

What are the main problems associated with surface and groundwater contamination?

Contamination of ground water can result in poor drinking water quality, loss of water supply, degraded surface water systems, high cleanup costs, high costs for alternative water supplies, and/or potential health problems. The consequences of contaminated ground water or degraded surface water are often serious.

How can we prevent groundwater contamination?

What can I do to reduce pollution?

  1. properly dispose of all waste; don’t dump chemicals down drains or on the ground.
  2. test underground fuel oil tanks for leaks; if possible, replace them above ground.
  3. safely store all chemicals and fuels.
  4. minimize the use of chemicals; always use according to directions.

Can you purify contaminated groundwater?

Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface. As a result, the contaminated groundwater is unsuitable for use.

How do you deal with groundwater?

If you want to protect your home from flooding, check out these tips.

  1. Get Appliances off the Floor. You may not have to actually do anything to stop groundwater from flooding your basement.
  2. Install a Sump Pump. There are different types of sump pumps, but all of them redirect water.
  3. Fill the Basement.
  4. Raise the House.

How we can increase ground water level?

Ground water level can be increased by ground water conservation and control use of water. Protect : trees, water sheds,lakes, ponds, deep drilling for water in coastal areas and water conservations.

Which plants increase ground water level?

Some of the trees that can raise ground water level are:

  • Neem tree.
  • Ashok tree.
  • Tamarind/Imli tree.
  • Jamun tree.

Does rain increase ground water level?

“In north Karnataka and other rural areas, water levels have gone up because of the rains. There, people stop using borewells during the monsoons, and there is time and surface area for water to percolate and recharge. Because of this, water levels will not rise as much as we expect,” an official said.

What is the method used to recharge the groundwater?

Subsurface Groundwater Recharge Wells Recharge or injection wells are subsurface groundwater recharge techniques used to directly discharge water into deep water-bearing zones. Recharge wells can be cased with the material covering the aquifer.
