    Abstract

    Two-dimensional depth-averaged schemes are able to represent variations in the velocity distribution in a channel. This paper deals with the application of two dimensional depth-averaged model (RMA2) to the Santa Cruz river, an ephemeral channel that is overgrown with vegetation. Vegetation has taken hold in the near dry river bed causing widely varying conditions across the channel. A two dimensional simulation may improve the representation of a river. To examine this hypothesis, steady flow simulations from RMA2 are compared with results from HEC-RAS under the one-dimensional steady water profile simulation option. Maximum flooding depths, floodplain widths, and velocities are compared and show a significant difference in flow velocities across the section.
