As a hydrologist and civil engineer, Steven’s expertise is in flood hydrology, hydrologic modeling, stream mechanics and fluvial geomorphology, and stream restoration. He consults on stream-related issues across the United States, working for over 30 years as a practitioner and researcher for the US Forest Service, the USDA Natural Resources Conservation Service, the US Geological Survey, other federal and state agencies, and private consulting. Steven was granted a doctorate in Civil Engineering from Colorado State University in 2010, with a dissertation focused on flow resistance in high-gradient streams. He was a returning adult student for his PhD studies, after spending a decade working as a practitioner. He specializes in applying new concepts and tools in the design and management of stream-related infrastructure, and in developing publications and tools that straddle academia and practice to move science and technology forward for the benefit of society and the environment.
