Estimation of Open Channel Roughness by using Gradual Varied Flow Profiles- Juniper Publishers

Estimation of Open Channel Roughness by using Gradual Varied Flow Profiles in Juniper in Civil Engineering Research Journal (CERJ)

Open channel flow parameter estimation is an inverse problem, which involves the prediction of a function within a domain, given an errorcri! Terion with respect to a set of observed data. Various numerical methods have been developed to estimate open channel flow parameters. For this study, Genetic Algorithm optimization technique is selected. Because of its inherent characteristics, genetic algorithm optimization technique avoids the subjectivity, long computation time and ill-posedness often associated with conventional optimization techniques. An accurate estimation of roughness coefficients is of vital importance in any open channel flow study. In flood routing in natural rivers, most channels have compound sections and the roughness values in main channel and flood plains are usually different.
