Software & Tools

RMC Overtopping 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 assess riprap stability, assess adjusted overwater wind speed and wind setup, and assess wave properties, wave runup, and wave overwash.

RMC Scour Behind Floodwalls Toolbox
 
RMC WinDAM Embankment Vegetation Parameters Toolbox

The spreadsheet tools contained in this toolbox deterministically and probabilistically assess the likelihood of instability of riprap-armored embankments subjected to overtopping using the methods of Thornton et al. (2014), Frizell et al. (1998), and Mishra and Ruff (1998). This assessment supports the evaluation of the likelihood of initiation of embankment overtopping erosion.

  

The spreadsheet tools contained in this toolbox estimate the adjusted overwater wind speed using EM 1110-2-1100, wind setup using EM 1110-2-1420, wave properties using EM 1110-2-1100 and Wilson (1965), and wave run-up and wave overtopping using the EurOtop manual (2019).

  

The spreadsheet tools contained in this toolbox assess the scour behind floodwalls due to overtopping using the boundary shear stress approach below an overfall of Robinson (1992) and the free-falling jet approach of Mason and Arumugam (1985). The critical shear stress for the vegetal cover is assessed using the methods of the U.S. Natural Resources Conservation Service (NRCS) (2007) and published values.

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

The spreadsheet tools contained in this toolbox assess the overtopping of grass-covered slopes caused by reservoir overfilling, passing of flood waves in rivers, or storm surges in coastal estuaries without waves using the methodology of Hughes and Thornton (2015) and erosional limit for grass to inform likelihood of removal of grass cover or screening of embankment overtopping with breach, as well as deterministically and probabilistically assess the likelihood of embankment breach from overtopping erosion using physically based model results (such as WinDAM C) and user-specified erodibility parameters for the embankment.
