WebIntroduction to Unit Hydrographs. A unit hydrograph shows the temporal change in flow, or discharge, per unit of runoff. In other words, how the flow of a stream will be affected over time by the addition of one unit of runoff. The unit hydrograph is a useful tool in the process of predicting the impact of precipitation on streamflow. WebWhat concepts can be explained using this diagram? A) The movement of water between the oceans and the land B) How precipitation ends up in rivers or groundwater C) How weathering causes the seas to become saltier D) All of these are correct. D) How does the character of a rock influence weathering?
