Abstract

Safety assessment of flood control structures (FRS) or dams located in alluvial basins in the desert southwest commonly includes characterizing the existing or potential future hazard to these structures due to ground pumping-induced subsidence. Differential subsidence can lead to changes in surface hydrology and flood storage capacity, and possible earth fissuring that might cause a piping erosion FRS failure during a flood event. For these studies, the authors typically use deep Wenner array resistivity as a reconnaissance tool to assess compressible basin alluvium and possible relatively shallow (<300 meters depth) bedrock.
