Description

Sediment accumulation poses the problem of decreased water storage in man-made reservoirs. The optimal way of identifying the topography and sediment levels in a lake is to use ground penetrating radar (GPR). This study was conducted using a GSSI SIR3000 and a 100MHz antenna combined with a high resolution sub-metric GPS system. The GPR antenna was placed in an inflatable boat powered by an electric trolling motor. A total of 19 transects were performed along the entire length of the lake and a three-dimensional bathymetry and sediment accumulation models was performed. Both water and sediment deposit volume were defined using a grid volume computation. Both The bathymetry, volume of sediment, and its accumulation rate were estimated.
