Water moves around our planet in multiple ways. Runoff includes not only the waters that travel over the land surface and through channels to reach a stream but also interflow, the water that infiltrates the soil surface and travels by means of gravity toward a stream channel. At its core, the water cycle is the motion of the water from the ground to the atmosphere and back again. Broadly speaking, runoff refers to the movement of liquid water out of an area, but the specific meaning depends on how that area is defined: Some sources use runoff to refer to overland flow: the rapid movement of water across the land surface (generally towards a stream) in This water may travel to a river, lake, or ocean. Sep 15, 2014 · Runoff is the water that flows across land’s surface and into aquifers or rivers, replenishing the water cycle and the water supply. The presence of excessive contaminants in the atmosphere and water bodies decreases the evaporation and condensation on earth, thus adversely affecting the water cycle. This happens when the ground can't soak up any more water, like after a heavy rain or when snow melts. Runoff is an important component of the water cycle. Infiltration For some purposes however, the definition of runoff also includes water which makes its way relatively quickly to the stream channel just below the surface. This picture is what is known as the water cycle. Runoff is that part of the precipitation, snow melt, or irrigation water that appears in uncontrolled surface streams, rivers, drains, or sewers. offsite link The water cycle is often taught as a simple, circular cycle of evaporation, condensation, and prec Jun 11, 2025 · Learn the fundamentals of runoff, its significance in water resources engineering, and its impact on the environment and human societies.
