Changes in land use and climate have substantial environmental consequences, especially on water resources. In this research, the effects of urbanization and climate change on water resources were investigated. Moreover, a tool was derived to examine land use change and to postulate future land use patterns. Most importantly, the effectiveness of Best Management Practices (BMPs) in reducing stormwater runoff was explored. This dissertation consisted of three articles based on different case studies at varying spatial locations and spatial scales. Comprehensive geospatial methods were used throughout the entire research, which included modeling and analyzing land use change, landscape patterns, population growth, climate change, hydrologic process, and the cost-effectiveness of BMPs. The first two articles were pilot studies of this research. They focused on developing a population-coupled Markov Cellular Automata (CA-Markov) land use change model. The reliability and applicability of the model were ascertained by generating land use maps for the Little Miami River Watershed in Ohio and the Las Vegas Wash Watershed in Nevada. The third article was a continuation of the first two pilot studies. Using the techniques developed earlier, future land use scenarios were generated for a smaller subwatershed of the Las Vegas Wash Watershed, the Duck Creek Watershed. Together with the future climate scenarios postulated by the Intergovernmental Panel on Climate Change (IPCC), they were used to assess the future hydrologic conditions in this hot, arid, and urbanized watershed. System for Urban Stormwater Treatment and Analysis Integration (SUSTAIN) was further used as a geospatial decision support system to model the watershed hydrologic process and the cost-effectiveness of BMPs in reducing potential stormwater runoff under future scenarios of climate and land use changes. This research contributes to the advancement of watershed studies using integrated geospatial technologies. By using a case study of an arid and urbanizing watershed, it provides useful information to sustainable watershed development and urban stormwater management, as well as in devising adaptation plans to future climate and land use changes.
