Abstract The FLDWAV allows users to build a mathematical model of a river system and to calibrate their model to observed data (if available). The program may then be used to compute eater surface elevations and discharges throughout the model for any given inflows or stages defined at the boundaries of the model. The program is also able to compute discharges resulting from the failure of a dam and to and to subsequently, or simultaneously, route the discharge downstream. The SMPDBK program allows users to build (easily and quickly) a simplified mathematical model of a dam/channel/valley, simulate a dam breach, and compute approximate flood peak stages, discharges, times of arrival, and duration. The BREACH program allows the user to build a mathematical model of an earthen dam based on fill material characteristics and dam dimensions. The dam may then be breached using various failure scenarios. The final result of the model is a computed discharge hydrograph through the breach.
