Stream or Riverine Hydrograph

Information on the stream or riverine hydrograph is provided by the user as a set of time-discharge pair. The hydrograph can be obtained from the TR-20 output data or any other hydrologic program. The user also can use the hydrograph generation unit of this program to generate a hydrograph based on the TR-20 single area model. The required data for hydrograph generation includes, drainage area, time of concentration, composite runoff curve number (RCN), rainfall, base flow, and the physiographic region in Maryland (different regions have different peak factors).
