Professor (current rank), Department of Biological and Ecological Engineering
Oregon State University, Corvallis - August 1978 to Present
Research Program - Measurement and simulation of soil water distribution in field conditions and design of monitoring systems. Determination of local and regional scale evapotranspiration and crop water use. Applications of remotely sensed data and geostatistical analysis to water resources evaluation and hydrologic balance modeling. Measurement of diurnal radiation and energy balance over land surfaces and longer term hydrologic balance based on soil water monitoring.
Academic Program - Senior and graduate level courses in design of irrigation and drainage systems and water distribution systems. Graduate courses in physical hydrology, advanced concepts in hydrologic analysis, regional hydrologic modeling, open channel hydraulics and sediment transport.
