Genetic Algorithm Based Model for Optimal Selection of Open Channel Design Parameters

Abstract Open channels are one of the most used water conveyance systems for delivering different purposes. Existing models design open mainly assume uniform flow, focus on cross-section sizing, and generally decouple sizing from selection channel alignment profile. In this study, we developed an optimization model a comprehensive transmission channels. The minimizes sum costs earthwork, lining, losses, land acquisition; accounts non-uniform, mixed-regime flow; considers multiple geometric hydraulic constraints. was validated using several idealized scenarios. potential in minimizing cost real projects demonstrated through application to existing irrigation canal Egypt (the Sheikh Zayed Canal). results validation scenarios matched anticipated outcomes profile reproduced analytical solutions given literature design. Application Canal gave more optimal design; OCCD produced alternative with ~27% less than constructed alternative.
