Getting Started

BSTEM toe erosion and bank failure analysis will be performed as part of a sediment transport analysis on any cross section bank that has all the necessary parameters. Computing bank failure at every bank will increase run times. Therefore, it may be advantageous to only specify BSTEM parameters for banks that have a probability of failure.

To enter BSTEM data in HEC-RAS, from the HEC-RAS main Window, from the Toolbar, click Sediment Boundary Conditions (below). Bank failure analysis is currently only computed as part of a sediment transport analysis. The Sediment Data Editor will open (bottom). From the Sediment Data Editor the user will enter standard sediment transport data on the first two tabs (bottom). To enter BSTEM information, click the USDA-ARS Bank Stability & Toe Erosions MODEL (BSTEM) tab (bottom).
