Abutment Scour with Future Channel Movement
Where abutments are set well back from the channel, the user is encouraged to consider the potential for the channel to move laterally to the face of the abutment. This utility simplifies the computations. The recommended approach is to first run ABSCOUR 10 to compute abutment scour for proposed conditions. Then open the utility and select the button for "Import Data from Recent ABSCOUR Run." The program will prompt you to select either the left (L) or right (R) abutment. The program computes abutment scour under (potential) future conditions where the channel moves into the abutment.
