Abstract: A weighted implicit finite-volume model is developed to simulate two-dimensional diffusion flow in arbitrarily shaped areas. The model uses a mixture of unstructured triangles and quadrilaterals to discretize the domain, ...

Abstract: Unsteady canal flow in an integrated canal-flow–groundwater-flow system is analyzed by solving the coupled equations governing canal flow, groundwater flow and the seepage between them. Analytical solutions are obtained ...

Abstract: Singular value decomposition is used to calibrate the Manning's roughness coefficients in a one-dimensional unsteady flow model of the Upper Niagara River. The method is used to solve for the parameters after formulating ...

Abstract: Two regional models, the South Florida Water Management Model (SFWMM) and the Natural System Model (NSM), are applied to analyze and predict water conditions in the Everglades and South Florida. Both of these models use ...

Abstract: With the increased emphasis on developing integrated models capable of simulating runoff through hydrologic systems that include hillslopes and wetlands, analytical solutions have become useful in analyzing and testing ...

Abstract: Diffusion-wave and kinematic-wave approximations of the St. Venant equations are commonly used in physically based, regional hydrologic models because they have high computational efficiency and use fewer equations. ...

Abstract: A computer model RICE is developed for simulating ice processes in rivers. In the river‐hydraulics component, the flow condition is determined from one‐dimensional unsteady flow equations. In the thermal component, ...

Abstract: South Florida has a complex regional hydrologic system that consists of thousands of miles of networked canals, sloughs, highly pervious aquifers, open areas subjected to overland flow and sheet flow, agricultural areas ...

Abstract: This paper presents the formulation of a one-dimensional river-ice simulation model RICEN. The model consists of two major parts: (1) An unsteady flow model for a channel network with ice; and (2) a thermal and ice condition ...
