Computer-aided dam break flow routing

Abstract

A computer aided dam-break flow routing program, CADAMBRK, has been developed on the Integraph system. CADAMBRK is based on the widely used dam break analysis program, DAMBRK. However, unlike DAMBRK which uses the rigidly formatted text data file. CADAMBRK operates in a user friendly environment and possesses three additional special features, namely: (1) a digital terrain model, (2) a markedly enhanced graphical plot capability for hydrograph and flood zone identification, and (3) suggested values for overland flow roughnesses to be used in the dam-break generated flood routing. The paper discusses the structure of the program, the various representative modules, and presents results of a hypothetical dam break generated flood.
