Question

Quizplus · Accepted Answer

Base flow refers to the portion of streamflow that comes from groundwater seepage into the river channel. It is a slow and steady contribution to the streamflow over time, and it is not influenced by precipitation or other surface water inputs. Saturated flow refers to the movement of water through porous media (such as soil) where all of the void spaces are filled with water. Overland flow refers to the movement of water across the surface of the land, often in the form of runoff during rainfall events. Surface runoff refers to the movement of water over the land surface and into streams or other bodies of water.
