Abstract : This is Volume 4 of the 12 Volume report prepared by The Hydrologic Engineering Center of the U.S. Army Corps of Engineers as a contribution to the International Hydrological Decade. This volume describes practical techniques for analyzing precipitation, snowmelt, infiltration, and runoff processes as they relate to the computation of flood hydrographs. Topics discussed include: Estimation of the areal depth and distribution of precipitation; Calculation of runoff from snowmelt; Determination of loss rates by linear and nonlinear functions; unit hydrograph theory and derivation; hydrograph reconstitution; and the Estimation of unit hydrograph and loss rate coefficients for ungaged areas. Descriptions of generalized computer programs for 'Basin Rainfall and Snowmelt Computations' and 'Unit Hydrograph and Loss Rate Optimatization' are included as appendices. (Author)
