IdahoPower Company (IPC) maintains an active monitoring campaign of the Snake River in Hell's Canyon, which relies heavilly on repeat multi-beam echo-sounding (MBES) surveys.The primary purpose of this project is to recommend peer reviewed and scientifically defensible methods that facilitate accurate geomorphic change detection of MBES data by adhering to best practices in the fields of topographic surveying and analysis. The recommended methods address field data acquisition, data post processing, and change detection using post processed data.
