dc.descriptionAbstract: A numerical model study of the Waimea River, Waimea, Kauai Island, Hawaii, was conducted to evaluate aggradation problems adjacent to a US Army Corps of Engineers levee, and to determine if the flood-control capability of the levee was reduced. The TABS-1 one-dimensional numerical model was used. Sediment inflow data were not available, and therefore sediment inflow was used as an adjustment parameter in the numerical model. The model was adjusted by reproducing measured historical aggradation using both multiple and single grain size sediment transport functions. Measured degradation that occurred during a historical period was used to test the model performance. Using the single grain size function, the numerical model could not be adjusted to simulate both the aggradation and degradation periods. However, the model was successfully adjusted to both historical surveys using the multiple grain size function. The adjusted model was then used to evaluate bed response during the design flood hydrograph. Appendix A presents a detailed description of the TABS -1 numerical model.-
