Richard E. Howitt is professor of economics at the University of California, Davis. Dr. Howitt’s research focuses on resource and environmental economics, quantitative methods, and econometrics. His interests include developing calibration methods based on maximum entropy estimators to model the economic structure of resource use from disaggregated physical data, including remote sensing methods, to infer the underlying economic functions. Much of his research has focused on California’s water resources, including water markets in the San Joaquin Valley and the Westlands Water District. He has published in such areas as river water quality, water use, water management, and water institutions. Dr. Howitt received his Ph.D. and M.S. degrees in economics from the University of California, Davis.
Margaret A. Palmer is professor and director of the University of Maryland (UM) Center for Environmental Science, Chesapeake Biological Laboratory. She has also served as the director of the Ecology Program at the National Science Foundation (NSF), director of the Biological Sciences Program at UM, and visiting scientist at the Smithsonian Institution.

John Pitlick is an associate professor in the Geography Department, University of Colorado-Boulder, and Faculty Affiliate of the Environmental Studies Program. Dr. Pitlick’s research interests are in the areas of surface-water hydrology and fluvial geomorphology. His research focuses on processes of sediment transport and channel change in both natural and altered river systems. The principal goal of this research is to develop process-based models coupling hydrology, sediment transport, and geomorphology across a continuum of scales. Additional research being done in collaboration with fisheries biologists and aquatic ecologists seeks a more detailed understanding of interactions between geomorphology and ecosystem processes, including food-web dynamics and nutrient cy-
cling. In addition to field-based research, he has initiated laboratory studies to model stream-channel response to flood flows, and completed a hydrologic analysis of the effects of post-1950 changes in temperature and precipitation on the timing and volume of runoff in rivers throughout the western United States.
