Abstract: Overtopping of embankments during floods leads to a spatially varied flow (SVF). In order to estimate the water surface profiles and the amount of water spilling over the embankment for a given steady-state flow condition, ...

Abstract: For channels with composite roughness, an equivalent uniform roughness coefficient and flow geometric elements are used in an optimal design method using the Manning equation. The optimal design problems are formulated in ...

Abstract: Optimization-based models for simulation of tile drainage systems are formulated and solved with a finite-difference approximated Richard's equation as an embedded constraint. The solution methodology minimizes the sum of ...

Abstract: A methodology for parameter estimation for the Muskingum model of streamflow routing is developed. The methodology minimizes the outflow prediction errors subject to the satisfaction of the streamflow-routing equations for ...

Abstract: The cost of open channels can be minimized by using (1) the optimal design concept; (2) a new geometric shape to substitute for the trapezoidal channels, and/or (3) a composite channel. The channels in which the roughness ...

Abstract: Trapezoidal open channels are designed for specified slope, specific lining materials, and for a specified design flow. These input design parameters are prone to uncertainties. The freeboard is used to confine the flow ...

Abstract: The channel dimensions leading to the critical state of flow are important in the design of channel transition. This work describes a methodology for determining the channel dimensions leading to the critical state of flow ...

Abstract: Two mathematical models for parameter estimation in closed-loop, open-channel flow networks are presented. The parameter estimation models seek to determine the parameter values that would reproduce an observed flow profile ...
