RMC-RFA Software

The USACE Risk Management Center (RMC) developed the RMC-RFA software to facilitate hydrologic hazard assessments within the USACE Dam Safety Program. RMC-RFA produces a reservoir stage-frequency curve with uncertainty bounds by utilizing a deterministic flood routing model while treating the inflow volume, the inflow flood hydrograph shape, the seasonal occurrence of the flood event, and the antecedent reservoir stage as uncertain variables rather than fixed values. In order to quantify both the natural variability and knowledge uncertainty in reservoir stage-frequency estimates, RMC-RFA employs a two looped, nested Monte Carlo methodology. The natural variability of the reservoir stage is simulated in the inner loop defined as a realization, which comprises many thousands of simulated flood events. Knowledge uncertainty in the inflow volume frequency distribution is simulated in the outer loop, which comprises many realizations.


This is the Risk Management Center – Reservoir Frequency Analysis Software, RMC-RFA version 1.1 used for stochastic reservoir stage-frequency analysis for a PA or an SQRA-level Dam Safty
