Abstract

Rapid hydraulic structures are used in Poland Stream Mountains excessively to regulate flow by changing its slope at certain locations while allowing for fish passage. Local scour downstream the rapid is an important issue regarding its safety. This paper presents experimental investigation for scour holes downstream a rapid structure using a small scale physical model. Results are used with other data presented in literature for similar structures to develop an equation for the prediction of maximum scour hole downstream rapids. For this purpose Genetic Programming (GP) is utilized as a tool for developing the required relation. It is shown that GP could produce formulae relating scour hole depth and various parameters with less error than some of available regression equations
