Runoff

Definition: runoff

runoff: The flow of rainwater or melted snow from the surface of land into streams and rivers; the flow of excess fertilizer or pesticide from farmland into rivers. Nitrate runoff causes pollution of lakes and rivers. Fish are extremely susceptible to runoff of organophosphates; the portion of rainfall which finally reaches a stream. Managing runoff helps farmers protect water quality and ensure sustainable land use.
