Guam hydrologic information, of streamflow duration curves, is the second WERI online data visualization interface, a MAppFx product. The streamflow duration curves of the Ugum River in the Ugum Watershed, Southern Guam, are the first phase of streamflow duration curves that are available online. The flow duration curves are based on WERI analysis research (Heitz and Khosrowpanah 2015). MAppFx is an intuitive data visualization interface that features a map of the Ugum River, as a polyline of segments that upon selection opens the section of the river’s flow duration curve (graph). This means of information transfer makes quick hydrologic reference of a select site along the river. The next phase updates the map to include all the flow duration curves segments from every mapped stream/river in Southern Guam.

While online data visualization is gaining popularity in the earth sciences, outreach is key to ensure interagency partners and researchers have access, familiarization, and utility training for complete product success. WERI has already introduced an early development introduction of this product in a WERI Guam Hydrologic Forum, November 2022, which received feedback of amazement and gratitude. Other upcoming WERI hosted venues will bring this product on stage to gain popularity and familiarization as a valuable data source for determining feasibility of watershed development.
