Biography

Dr. Ham is a senior research scientist. He provides decision support related to the operation and configuration of the Columbia and Snake River hydrosystem to optimize juvenile salmonid survival, costs, and power production. Dr. Ham's research projects include assessing the risk of multiple turbine passage on survival of emigrating juvenile salmonids, directing the development of software to process and display acoustic tag data within a GIS map, and developing software to estimate fish passage from fixed-location hydroacoustics at Columbia River Basin hydropower projects operated by the Corps of Engineers. His research has evaluated the sensitivity of hydroacoustic fish passage estimates to errors in detectability model inputs and developed a model of the risk of stranding for chinook salmon smolt in the Hanford Reach of the Columbia River. Dr. Ham directs the development of software tools to process and analyze tagged fish movements. These tools are used to evaluate fish passage at dams and measure other risks to anadromous fishes.

Research Interests
