Abstract

This study aims to investigate the enhanced accessibility and scalability of the SWAT-DEG model deployed as a cloud service. Frequent monitoring of hydrologic processes and simulation modeling on short (i.e., sub-daily) time steps are essential tools for effective stream rehabilitation and restoration on first and second order streams with drainage areas less than 20 square kilometers. The SWAT-DEG model was developed to assess how changes in climate and land use beget changes in watershed processes such as runoff, sheet and rill erosion, channel geomorphology and sedimentation. Deployment of the model on a user-friendly and scalable web-platform enables a broader population of watershed planners and decision makers to account for urban development, climatic variability and change, and other human activities in the planning process. The environmental Risk Assessment and Management System (eRAMS) was used to facilitate collection and organization of geospatial data, scenario assessment and visualization, and uncertainty analysis. The platform, eRAMS, is operating system independent and deployable on desktop or mobile devices. Implications for application performance and resource requirements (CPU, disk, and network) resulting from multi-tier applications of SWAT-DEG as a cloud service are discussed.
