Prediction of Hydrodynamics for Unidirectional Flow

Abstract

Our long term goal is to develop an understanding of the relationship between channel geometry and three-dimensional flow features in rivers. One application of such an understanding would be the prediction of channel geometry given observations of flow velocities. Assess the applicability of the Regional Ocean Modeling System (ROMS) to riverine environments. For this purpose we will utilize the Flow and Sediment Transport Morphological Evolution of Channels (FaSTMECH) model developed by the USGS for 3D river flow problems and compare results to ROMS-predictions as well as observations. Develop and test a parameter estimation routine in the ROMS modeling framework. Use this tool to determine channel topography given observations of flow velocities (either depth-averaged, or surface velocity observations) in the realistic setting of the Snohomish river, WA.
