What is a runoff simple definition?
Runoff can be described as the part of the water cycle that flows over land as surface water instead of being absorbed into groundwater or evaporating. Runoff is that part of the precipitation, snow melt, or irrigation water that appears in uncontrolled surface streams, rivers, drains, or sewers.
What is called runoff?
Runoff is nothing more than water “running off” the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
What is runoff water?
Runoff is the water that is pulled by gravity across land’s surface, replenishing groundwater and surface water as it percolates into an aquifer or moves into a river, stream or watershed.
What is meant aquifer?
aquifer, in hydrology, rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. An aquifer also may be called a water-bearing stratum, lens, or zone.
What is runoff quizlet?
Runoff. the occurrence of surplus liquid (as water) exceeding the limit or capacity. Watershed. a ridge of land that separates two adjacent river systems. Divide.
What is the definition of infiltration in geography?
Infiltration – Water soaks or filters into the soil. Surface runoff – Water moves across the surface of the earth becoming a stream, tributary or river. Percolation – Water moving from the soil into the spaces (pores) in the rock.
What is runoff and its types?
There are three major types of runoff depending on the source: surface flow, interflow, and base flow. These were discussed in Module 101 and are expanded upon here. Surface Flow. Surface flow is water that has remained on the surface and moves as overland or channel flow.
What is runoff in agriculture?
noun. the portion of rainfall that runs over agricultural land and then into streams as surface water rather than being absorbed into ground water or evaporating. pollution of the lagoon from pesticides contained in agricultural runoff from the surrounding area.
What does a runoff do?
Runoff: Surface and Overland Water Runoff A portion of the precipitation seeps into the ground to replenish Earth’s groundwater. Most of it flows downhill as runoff. 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.
What is meant by Artesian Basin?
A geologic structural feature or a combination of such features in which water is confined under artesian pressure.
What is 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. Water that seeps deep into the ground is called groundwater.
