RMC Risk Calculations 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 calculate dam and levee risks, assess probabilities for event combinations and joint loadings, and assess the effectiveness and efficiency of risk reduction for an array of risk management plans.

The U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) developed RMC-SQRAcalcs as part of the RMC Risk Calculations Suite of Microsoft Excel spreadsheets to support risk assessments for dam and levee safety. The spreadsheet tools contained in this toolbox assess the total incremental risk, non-breach risk for dams, and overtopping incremental and non-breach risk for levees to support semi-quantitative risk assessments for dam and levee safety using the methods of RMC-TN-2018-01 (O'Leary 2018). The total annual probability of inundation of the leveed area is assessed using the methods of ECB 2019-11 for National Flood Insurance Program (NFIP) accreditation recommendation.

 

The U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) developed the RMC Event Combination Toolbox as part of the RMC Risk Calculations Suite of Microsoft Excel spreadsheets to support risk assessments for dam and levee safety. The spreadsheet tools contained in this toolbox assess the probability of failure associated with multiple gates, the probability of a flood prior to completion of repairs following a breach, the joint occurrence of earthquake and flood events using the binomial discrete approximation (Hynes-Griffin 1980) and exponential continuous form (Ellingwood 1995), and the joint occurence of other events using the exponential continuous form (Ellingwood 1995).

 

The U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) developed RMC Joint-Loading Probability (Dams) Toolbox as part of the RMC Risk Calculations Suite of Microsoft Excel spreadsheets to support risk assessments for dam safety. The spreadsheet tools contained in this toolbox perform a risk screening based on the joint-loading probability of an earthquake and coincident reservoir level based on the seismic hazard, stage-frequency, and consequence relationships and assuming the conditional probability of failure given the joint loading is unity.

 

The U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) developed the RMC Risk Management Plans Toolbox as part of the RMC Risk Calculations Suite of Microsoft Excel spreadsheets to support risk assessments for dam and levee safety. The spreadsheet tools contained in this toolbox quantitatively assess the effectiveness and efficiency of risk-reduction for an array of risk management plans, including as low as reasonably practicable (ALARP) considerations, to help risk-informed decision making.

  The U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) developed the RMC Event Tree Toolbox as part of the RMC Risk Calculations Suite of Microsoft Excel spreadsheets to support risk assessments for dam and levee safety. This toolbox generates a standard format event tree based on user-specified input.
 
This is the RMC Event Tree Toolbox version 1.1.

A database of typical sub-event trees for common potential failure modes evaluated during dam and levee safety risk analysis has been developed using the RMC Event Tree Toolbox. The typical sub-event trees in the database should be used for reference and updated as needed to fit project-specific conditions.

This is the RMC Semi-Quantitative Risk Assessment (SQRA) Calculations Toolbox version 1.3.
