Abstract:

This paper summarizes the verification and application of a two-dimensional finite element model capable of simulating the complex circulation characteristics in marshes and wetlands for a variety of boundary and flow conditions. The new 'Marsh Elements and Culvert-Weir' version of computer program RMA-2V includes capabilities to simulate marsh hydrodynamics and culvert and weir flow along the margins of a marsh or wetland.
