Welcome to the SAWLS home page.  We are a multidisciplinary group focused on watershed hydrology housed within the College of Agriculture, Department of Renewable Resources at the University of Wyoming.  The group is composed of several graduate students, faculty and post-docs working on a variety of field applications, GIS and remote sensing research related to hydrologic modeling,  impacts of land cover change, and sustainable watershed management.  This site is intended to provide a brief overview of the ongoing projects in SAWLS. If you have any follow-up questions, please feel free to contact me.

Scott Miller is the director of SAWLS, a professor in the Department of Renewable Resources at the University of Wyoming. My job title is "spatial processes hydrologist" and I teach and pursue research in the general domain of  watershed hydrology. Long-term research interests lie at the intersection of human use, process-based understanding on hydrolical and geomorphic processes, and sustainable development. Short research blurbs can be read by following the links on the left.

Interdisciplinary Graduate Studies in Hydrology / Water Resources at Univ. of Wyoming

Dr. Miller is the Chair of the PhD program in Hydrologic Sciences and the MS program in Water Resources at the University of Wyoming.  These are two interdisciplinary graduate programs for students pursuing research and education in hydrology / water resources and are opportunities for students to expand their education and research outcomes by interacting with other students and faculty from across campus.


Summary of the SAWLS Research Program

Over the past several years we have been working on a variety of projects in which we have developed research applications related to both basic and applied research in hydrology and watershed management. In addition to field-based empirical research we construct GIS tools for automating hydrologic, geomorphic and ecological modeling processes.  While GIS approaches have provided useful advances for watershed management, they have proven to be most beneficial in providing a means for advancing our understanding of watershed processes. Specifically, the focus has been on projects involving multi-scale (both temporal and spatial) modeling for landscape assessment; the effects of watershed complexity on model results; information entropy and process representation as a function of scale; and remote sensing misclassification error in hydrologic investigations. Prior research projects have investigated linkages between watershed hydrology and fluvial dynamics, scale issues in watershed response, the sensitivity of hydrologic models to spatial data, and the impacts of map scale on geomorphic research.

A common thread runs through the SAWLS research experience and goals: multi-scale investigations into spatially distributed watershed processes with particular interest in fluvial dynamics and geomorphology. Emerging technologies are developed to serve as tools that allow us to probe questions that could not be addressed in their absence. However, the focus of this research has been on watershed processes and core hydrologic research, not on the technologies themselves. Many of the critical research issues in watershed hydrology and environmental science are multi-disciplinary and complex, and our research has benefited from a collaborative, inter-disciplinary approach.
