• Abstract:
  This manual describes how to use the Iowa Bridge Backwater software. It also documents the methods and equations used for the calculations. The main body describes how to use the software and the appendices cover technical aspects. The Bridge Backwater software performs 4 main tasks: Design Discharge Estimation; Stream Rating Curves; Floodway Encroachment; Bridge Backwater Bridge Scour. Design discharge estimation: Design discharges are estimated by 2 methods, both from USGS reports for flood frequency in Iowa (Lara, 1987, Eash, 2001). Stream Rating Curves: Stage versus discharge relationships for streams are estimated using the Manning Equation and assuming uniform flow. This is a user friendly replacement for the PC VAL program previously used in Iowa.
