Several alternative dam-breach flood forecasting models are evaluated and compared based upon a consideration of he underlying concepts and theory incorporated into the models b findings reported in the published and unpublished literature with respect to application, testing, evaluation, and comparison of various models and c results obtained and experience gained in applying the models to several case study data sets. The objective is to provide an assessment of the state of the art of dam-breach flood forecasting which can serve as a basis for selecting and adapting specific models for military use. The comparative evaluation focused on the following leading dam-breach flood wave model which are representive of the current state of the art DAMBRK, FLOW SIM 1, FLOW SIM2, HEC-1,SMPDBK, TR 66, and the HEC dimensionless graph procedure. A set of dam-breach flood forecasting methods developed during the 1950s and early 1960s were also reviewed, as was the recently developed Military Hydrology Model MILHY. Although MILHY is a rainfall-runoff model with no special features for dam-breach modeling, a breach simulation routine could be added. DAMBRK and SMPDBK were determined to be the optimal models for military application.
