FINITE ELEMENT SURFACE-WATER MODELING SYSTEM: TWO-DIMENSIONAL FLOW IN A HORIZONTAL PLANE. USERS MANUAL

The Finite Element Surface-Water Modeling System: Two-Dimensinal Flow in a Horizontal Plane (FESWMS-2DH) is a modular set of computer programs that simulate surface-water flow that is essentially two-dimensional in a horizontal plane. The modeling system was developed to analyze primarily flow at highway bridge crossings where complicated hydraulic conditions exist. However, FESWMS-2DH can be used to model many different steady and unsteady flow conditions. The core of FESWMS-2DH consists of three distinct but related programs: DINMOD, the data input module; FLOMOD, the depth-averaged flow solution module; and ANOMOD, the analysis of output module. DINMOD prepares a finite element network for use by other FESWMS-2DH programs. FLOMOD solves the vertically integrated conservation of momentum equations and the conservation of mass (continuity) equation to obtain depth-averaged velocities and water depth at points in a finite element network. ANOMOD generates plots and reports of computed values that simplify interpretation of simulation results. This manual provides users of FESWMS-2DH the information needed to use the modeling system effectively. The manual describes the logical structure of the modeling system, input data requirements, the output that is produced, and the means of interpreting the results.
