Military hydrology: report 13: comparative evaluation of dam-breach flood forecasting methods.
Several alternative dam breach flood forecasting models are evaluated and compared based upon: (1) consideration of the underlying concepts and theory incorporated into the models; (2) findings reported in the published and unpublished literature with respect to application, testing, evaluation and comparison of various models; and (3) results obtained and experience gained in applying the models to several case study data sets. The comparative evaluation focussed on the following leading dam breach flood wave models which are representative 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 1950's and early 1960's 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 modelling, a breach simulation routine could be added. DAMBRK and SMPDBK were determined to be the optimal models for military application. (from author's abstract)
