Applying State Space Equations in the Designing of the outlet gate dam with two reservoirs and its smart

Factors such as improper performance of gates, their failure, and inappropriate design of gate dimensions are likely to be followed by dangerous dam overtopping. In this article, the nonlinear equations expressing the flow rate through the dam bottom gate or intake as well as the water head inside t...
