Abstract
This research produces an optimization model for open channel comprehensive design (OCCD) using MATLAB. The OCCD minimizes the overall cost (e.g. Earthwork, lining, water losses, and land acquisition) by optimizing the open channel design parameters (e.g. Channel alignment, profile, and cross-section). The interdependence between the design parameters makes the traditional design methods less integrated as it approaches each stage independently. Furthermore, the optimization is subjected to geometric and hydraulic constraints (e.g. Restricted area, and maximum allowable velocity). The model was validated using several scenarios, which were compared to analytical solutions in the literature and newly formulated equations derived in this thesis. Furthermore, to demonstrate the model potential in minimizing the cost of real open channel projects, the model was applied to two case studies. The validation scenarios results were identical to the anticipated outcomes. It was also able to determine more optimal design alternatives with significant cost reduction for the Sheikh Zayed canal in Egypt and Al-Kharj flood control channel in Saudi Arabia
