Where does water end up after runoff?
Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds.
Where do underground water and runoff usually end up?
Runoff, and groundwater seepage, accumulate and are stored as freshwater in lakes. Not all runoff flows into rivers, though. Much of it soaks into the ground as infiltration.
Where will groundwater eventually end up?
The part that continues downward through the soil until it reaches rock material that is saturated is groundwater recharge. Water in the saturated groundwater system moves slowly and may eventually discharge into streams, lakes, and oceans.
Where does groundwater go?
Groundwater discharges into lakes, streams, and wetlands. This usually occurs as underground seepage. However, you may have seen a spring before, such as in the picture below.
Is runoff good or bad?
Runoff is extremely important in that not only does it keep rivers and lakes full of water, but it also changes the landscape by the action of erosion. Runoff of course occurs during storms, and much more water flows in rivers (and as runoff) during storms.
How can we prevent stormwater runoff?
You can do a lot to help minimize stormwater problems
- Maintain your car or truck.
- Wash your car at a commercial car wash rather than in the street or in your driveway.
- Drive less.
- Cut down on fertilizers, pesticides and herbicides.
- Remove part or all of your lawn.
- If you are on a septic system, maintain the system.
What happens to the rain water after reaching the ground?
Once on the land, rainfall either seeps into the ground or becomes runoff, which flows into rivers and lakes. Water falling on uneven land drains downhill until it becomes part of a stream, finds a hollow place to accumulate, like a lake, or soaks into the ground.
Where does stormwater runoff go after it leaves the ground?
Drainage ditches to carry stormwater runoff to storage ponds are often built to hold runoff and collect excess sediment in order to keep it out of streams. Runoff from agricultural land (and even our own yards) can carry excess nutrients, such as nitrogen and phosphorus into streams, lakes, and groundwater supplies.
How does groundwater flow from the ground to the surface?
But here the driveway was dug deep enough into the ground so that it cut into the permeable layer of soil that carries the underground water downhill. Thus, you can see groundwater seepage coming to the surface. By the way, it is seepage such as this that helps keep water flowing in many creeks and streams during periods of drought.
What can I do to reduce stormwater runoff in my yard?
Line impervious surfaces with gravel trenches. Figure out where water runs off your driveway or patio, and then dig a small trench along the edge. Fill it with gravel to slow the runoff and allow the water to seep into the soil. Use the water that drains off your roof.
Where does rain water go after it leaves the ground?
A significant portion of rainfall in forested watersheds is absorbed into soils (infiltration), is stored as groundwater, and is slowly discharged to streams through seeps and springs.
