A web-based platform for integrated real-time water Information: A prototype system for Missouri

Abstract

The study demonstrates a framework to develop a web-based platform that presents real-time water data from observations, model estimations, and model predictions over a pilot domain in Missouri, United States. The Missouri Water Information System (MoWIS) is a prototype water information portal that provides current hydrologic (rainfall, drought, and stream) conditions and future stream predictions based on national radar and stream monitoring networks. The primary data sources are USGS and NOAA APIs for river stage/streamflow observations and forecasts. The platform visualizes these data within a geospatial context through a map-based environment, accessible upon user interaction, to facilitate intuitive interpretation and spatial analysis. With a modular architecture designed for system scalability, the platform supports fully automated operations and responsive performance by offloading intensive data processing and modeling tasks to external servers. Since the platform leverages nationally available web services, the framework is readily transferable to other geographic regions.
