Abstract

In this paper a Genetic Algorithm developed by Duan et al (1992) has been used to evaluate and modify the structure of "Tank Model" for two different basins in the northeastern Brazil for daily and monthly data. The algorithm entitled "Shuffled Complex Evolution - SCE" is based on the formulation and natural evolution of multiple initial complexes (parameter sets). It combines the power of the Simplex Method with the concepts of controlled random search and extraction of genetic operators generating shuffled complexes of the parameter values. The Tank Model With its structure consisting of a set of linear reservoirs in series or parallel with side and bottom passages has been found to give good results for the semi-arid basins in th
