US Geological Survey
Hydrologist (Civil Engineer)
Columbus, Ohio

I've worked in OH for 31 years. My main areas of work involve hydrologic and hydraulic analyses, surveying, and GPS. I've taught classes on HEC-RAS modeling, GPS surveying, and indirect estimation of discharge. Work has led me to more than 30 details (for high-water mark documentation and indirects) in 18 states giving me the chance to visit the nicest of places at the worst of times.
