This study employs SRH-2D to investigate the impact of reservoir geometry on drawdown flushing efficiency. The model was first calibrated using data from a 2014 flushing event, reproducing observed sediment release concentrations and loads. To examine the influence of reservoir shape, simulations were conducted with various modified geometries. Two approaches were employed: 1) altering reservoir width at different depths while maintaining constant capacity and 2) modifying reservoir width at ratios (0.5, 1, 2, 4) relative to the original width, with corresponding capacity adjustments. This folder includes all the mesh files created with software SRH-Mesh, and all the setup and selected result files for model calibrations, and numerical models for various reservoir types of and different drawdown flushing operations. Users and interested parties should reference the accompanying report for further information on how the model and simulation cases were developed and analyzed. The reservoirDrawdownFlushingNumericalModel.zip contains the files needed to run the numerical models that simulate reservoir drawdown flushing.
