Using HEC-RAS to Compute Ungaged Lateral Inflows
This section of the manual illustrates how to use the ungaged lateral inflow option in HEC-RAS. The ungaged inflow can be used either to recreate historical, lateral inflows, or it can be used in forecast mode to determine the inflows for future downstream routing. This section discusses the required input data and viewing the output. A more technical discussion of the numerical modeling can be found in the hydraulic reference manual.
