Surface runoff - Wikipedia
WEBSurface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.

WEBrunoff carries pollutants such as oil, dirt, chemicals, and lawn fertilizers directly to streams and rivers, where they seriously harm water quality. To protect surface water quality and groundwater resources, development should be designed and built to minimize increases in runoff. How Urbanized Areas Affect Water Quality Increased Runoff

Water Runoff - an overview | ScienceDirect Topics
WEBWater quickly runs off unprotected soil because raindrops free small soil particles that, in turn, clog holes in the soil and reduce water infiltration. This water runoff transports soil organic matter, nutrients, sediments, and pesticides to rivers and lakes where it harms natural aquatic species.
