2 Temporal Variability of Flow/Stage Quantity of water available at a specific location varies with time Lake Mead monthly average water surface elevation Average daily flow at a Perdido River gage Hydrograph s Hydrograph is a graph with stage or discharge versus time s For convenience, a hydrograph has been considered divided into storm runoff (direct runoff, surface response) and baseflow s A typical hydrograph consists of rising limb, crest segment, and recession
