Sensitivity Analysis of the Auxiliary Spillway Erosion Based on the Material and Structural Properties
Publication: Geo-Extreme 2021
ABSTRACT
This paper examines how the level of auxiliary spillway erosion varies depending on the material and structural properties of the spillway. A sensitivity analysis is performed to distinguish the variability in the auxiliary spillway erosion for the Willow Creek Dam, located in Montana, using Windows Dam Analysis Modules (WinDAM) C software. The geologic materials, geometric design parameters, and hydrologic data are considered for the overall sensitivity analysis. The test is performed by changing the input parameters in WinDAM C. It was observed the inflow hydrograph had the largest impact on erosion. The representative diameter, spillway width, and side slope ratio had intermediate levels of impact on erosion.
