Recent Advances in Sediment Transport Modeling

SEDflume measures erosion rates as a function of sediment depth (down to a meter or more) and at high shear stresses (up to 25 Pa for data collection) to improve our understanding and ability to predict sediment transport and the capabilities of numerical models. In this work, a sediment transport model is developed specifically to incorporate these data. This model is a significant improvement over previous models because it directly incorporates site-specific SEDflume data, while maintaining a physically consistent, unified treatment of suspended load and bedload. Experimental data from noncohesive sediment erosion experiments in a straight channel and around a 180° bend will be used to verify this model.
