Flow hydrograph
WebA runoff hydrograph represents the cumulative runoff resulted from surface and sub-surface (base flow) runoff. The surface runoff or direct runoff hydrograph is obtained from the total storm hydrograph by separating the base flow. The separation of base flow is an arbitrary manner, unless a large flow from the antecedent storm is available. WebFlooding will be enhanced if the time of the crest is coincident with high tides and strong onshore winds. Minor flooding of Mad River Beach Road near Tyee City.

The lag-1 hydrograph also shows the decreasing flow conditions as all points are below the 1x line. Additionally, the rate of change for the decrease is consistent. A power curve fitted to these points yields a recession equation for the general form aQ b where Q t+1 = 1. ...
