Runoff is liquid, especially water or rainwater, that flows off or drains away, as in the storm sewer could not hold all the runoff from the recent rains. this sense of runoff is often used in the context of environmental science. it often refers to water that flows into streams or back into the water supply rather than seeping into the ground.

Runoff is precipitation that did not get (infiltrated) absorbed into the soil or did not evaporate, and therefore, made its way from the ground surface into places that water collect. runoff causes erosion and also carry chemicals and substances on the ground surface along to the rivers where the water ends up. it can cause water pollution too.
Average Monthly Runoff From The Three Catchments In Stage
Combined sewers are designed to collect both sanitary sewage and stormwater runoff in a single pipe system. these systems were designed to convey sewage and wastewater to a treatment plant during dry weather. Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.this can occur when the soil is saturated by water to its full capacity, and that the rain arrives more quickly than the soil can absorb it. Runoff noun (liquid) [ u ] earth science water that flows away from high areas to low areas: houses and subdivisions can disturb spring water runoff from the mountains. Water, such as rainfall, and any sediments or other substances carried with it, that is not absorbed by the soil but instead flows away over the ground. Urban runoff is surface runoff of rainwater created by urbanization.this runoff is a major source of flooding and water pollution in urban communities worldwide impervious surfaces (roads, parking lots and sidewalks) are constructed during land development.during rain storms and other precipitation events, these surfaces (built from materials such as asphalt and concrete), along with.

The runoff management system must be composed of natural or manufactured runoff collection, treatment and containment devices that are capable of preventing, collecting, treating or containing runoff. select from the options presented below, keeping in mind that the objective of preventing, collecting, treating or containing runoff must be met. Runoff versus rainfall with separate curves for each month and a tabular adjustment for antecedent rain fall. this was an attempt to deal with event situations; however, the scatter of the data was still significant. kohler and linsley (1951) expanded upon the ap.
