Predictions of Bedforms in Tidal Inlets and River Mouths

Abstract

The objective of the proposed study was to use a self-organization model to predict bedforms in tidal inlets and river mouths. Specifically, an existing model would be further developed and used to predict multiple scales of bedform formation, growth, adaptation and migration. Predicted bedforms would be used to predict time-varying, dynamic roughness and friction factors to infom1 larger scale hydro- and morpho-dynamic models. Results suggest that multiple scales of bedforms exist simultaneously, complicating the interpretation of bed roughness. In addition, model results and data in the literature suggest that temporally varying flow results in temporally varying roughness.
