Hydrologic Cycle and Watersheds

Hydrologic Cycle Components Precipitation Infiltration Percolation Runoff Evapotranspiration

Watershed A basin, drainage or catchment area that is the land area that contributes runoff to an outlet point Outlet point Watershed boundary

Watersheds We all live in a watershed! Area of land from which all water drains, running downhill, to a shared destination - a river, pond, stream, lake, or estuary

3 Functions Captures precipitation – its characteristics influence how much is captured Stores water once it infiltrates into soil (important to plants) Slowly releases water into streams, rivers, oceans

Why are watersheds important? We all live in a watershed Activities within a watershed impact runoff and water quality of water leaving the watershed Must manage at a watershed level rather than other boundaries to attain goals related to runoff and water quality
