WebStorm Hydrographs The storm hydrograph (Fig. 1) is a graph on which river discharge (y-axis) during a storm, or single precipitation event, is plotted against time (x-axis). … WebStorm runoff moves more rapidly over smooth, hard pavement than over surfaces with natural vegetation cover. As a result, streamflow (or discharge, Q) undergoes changes in timing and magnitude. The rising limbs of storm hydrographs become steeper and higher in urbanizing areas. Recession limbs also decline more steeply in urban streams.
