Abstract

The impacts of boundary conditions on unsteady flow modeling in using the UNET model are discussed. The UNET model was used to evaluate the impact of using a single LDD or combinations of selected LDDs to reduce peak stages. Well-calibrated hydraulic models such as UNET model can simulate historic, real-time, and even forecasted flooding conditions. The analysis has shown that opening two spillways for flood diversion would not have much or any impact on the boundary conditions and is considered to be valid for such practices. The analysis also suggest that using flow hydrographs as upstream boundary condition is more appropriate and secure for LDD management and ecosystem restoration.
