This research uses a special open-source software called Tethys Platform to create improved tools for predicting and visualizing water conditions. Tethys helps develop web-based mapping applications that use current water data, ultimately helping people make better decisions about managing water resources. For example, the Great Lakes Viewer shows interactive maps of water levels, helping users understand changes over time and across different areas for better planning. Similarly, the Rivers Point App connects to the National Water Model to provide short-term river flow forecasts, offering insights into local water conditions. These applications demonstrate that open-source tools like Tethys can quickly turn research ideas into practical solutions, improving water prediction, enhancing data accessibility, and supporting smarter water resource management through modern technology.
