RMC Spillway Suite

The U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) developed a set of toolboxes to help dam and levee safety risk assessors evaluate and screen spillway erosion.

RMC Critical Velocity Toolbox
 
RMC Headcut Erodibility Index Toolbox
 
RMC Erodibility Threshold Toolbox
 
RMC WinDAM Spillway Vegetation Parameters Toolbox

The spreadsheet tools contained in this toolbox assess the critical velocity. This parameter supports the screening of spillway erosion failure modes.

  

The spreadsheet tools contained in this toolbox assess the headcut erodibility index using the methods of the U.S. Natural Resources Conservation Service (NRCS). This parameter supports the screening of spillway erosion.

  

The spreadsheet tools contained in this toolbox deterministically and probabilistically assess the likelihood of spillway erosion using the erodibility threshold method of Annandale (2006) and stream power considerations.

  

The spreadsheet tools contained in this toolbox assess the vegetation parameters for the WinDAM software. These parameters support the evaluation of spillway erosion.

This is the RMC Critical Velocity Toolbox version 1.1.

  

This is the RMC Headcut Erodibility Index Toolbox version 1.0.

   This is the RMC Erodibility Threshold Toolbox version 1.0.   This is the RMC WinDAM Spillway Vegetation Parameters Toolbox version 1.0.

RMC Rock Mass Erodibility Toolbox
            

The spreadsheet tools contained in this toolbox assess the spillway erosion class using the geological strength index modified for erodibility of Pells et al. (2017) and stream power considerations and general depth and extent of erosion based on case histories.

            

This is the RMC Rock Mass Erodibility Toolbox version 1.0.
