Dam‐Breach Flood Wave Models

Abstract

Significant advances in the state‐of‐the art of dam‐breach flood wave modeling have occurred during the past decade. A comparative evaluation of several leading models representative of the current state‐of‐the‐art included a comprehensive literature survey and application of the selected models to several case study data sets. A dynamic routing model should be used whenever obtaining a maximum practical level of accuracy is required and adequate manpower, time, and computer resources are available. The National Weather Service (NWS) Dam‐Break Hood Forecasting Model (DAMBRK) is the optimal choice of model for most practical applications. Some applications require the capability to perform an analysis as expeditiously as possible. The NWS Simplified Dam‐Break Flood Forecasting Model (SMPDBK) is the optimal choice of model for most of these types of applications.
