Norman Crawford pioneered development of computer simulation methods for hydrologic processes, including snow accumulation and melt, infiltration, soil moisture, surficial groundwater and actual evapotranspiration. He developed the Stanford Watershed Model as a doctoral dissertation at Stanford University in California , and later on the faculty at Stanford, directed NSF sponsored research on applications of continuous hydrologic simulation to water resource management.


As a principal in Hydrocomp Inc. Dr. Crawford contributed to the design and development of widely used modeling systems (HSP, HSPF, HFAM). The HSPF hydrologic/water quality model is distributed by the U.S. EPA and the U. S. Geological Survey. His interests include operational forecasting and optimization for reservoirs and hydropower systems, and spatial visualization of physical processes in watersheds. He has lectured and developed professional courses in twenty countries worldwide.


Dr. Crawford is a recipient of the American Institute of Hydrology, Ray K. Linsley Award for "Major Contributions to Engineering Hydrology" and the American Society of Civil Engineers, Ven Te Chow Award for “Lifetime achievement in the field of hydrologic engineering that is distinguished by exceptional and significant contributions in research, education, or practice”.


Dr. Crawford is a graduate of the University of Alberta (B.S. – Civil Engineering) and of Stanford University (M. S., Ph. D.).
