| A 2-dimensional numerical sediment transport model using erosion rates in undisturbed conditions has been developed and applied to calculating the suspended sediment concentrations and bed level changes in the Lower Fox River The model reduces inaccuracy of sediment model by using the accurate erosion rates obtained in a flume (called Sedflume). The flume has been developed to measure erosion rates as a function of sediment depth and at the situation of high shear stresses such as flood event. Both mechanisms of suspended load and bedload transport are included in the model. The model results were verified for the description of sediment transport in a straight channel and the sediment transport during flood event in the Lower Fox River The results of Lower Fox River simulation showed good agreements with the observed SS concentrations. This model can be used to simulate sediment transport under the high shear conditions such as flood. |
