Abstract: An optimal flow control methodology based on adjoint sensitivity analysis for controlling nonlinear open channel flows with complex geometries is presented. The adjoint equations, derived from the nonlinear Saint-Venant ...

Abstract: This paper presents a physics-based two-dimensional (2D) numerical model to simulate overland flows typically generated by rainfall of a storm event or multiple events in natural terrain with complex topography, landform, ...

Abstract: A quasi-three-dimensional coastal area morphological (Q3DCAM) model has been developed using the process-based approach. It is for simulating complex multiscale coastal processes, primarily morphodynamic changes of the ...

Abstract: A numerical method based on optimal control theories for identifying Manning’s roughness coefficients (Manning’s

Abstract: The phase-averaged depth-integrated vegetal drag force (Fv) directly impacts the mean water level (MWL) change in vegetation. Evaluated from linear wave theory, Fv integrated along the submerged part of vegetation becomes ...

Abstract: A process-based parametric closure model for estimating cross-shore sediment transport (CST) rate has been developed for simulating long-term shoreline evolution. The formulations of this closure model include calculations ...
