Development of a web-based tool for coastal water resources management
The sustainability of coastal water resources is being affected by climate change, sea level rise, and modifications to land use and hydrologic systems. To prepare for and respond to these drivers of hydrologic change, coastal water managers need real-time data, an understanding of temporal trends, and information about how current and historical data compare. Coastal water managers often must mak - Multimedia

The water cycle
An illustrated diagram of the water cycle. This is a modern, updated version of the widely used diagram featured on the USGS Water Science School. Notably, this new water cycle diagram depicts humans and major categories of human water use as key components of the water cycle, in addition to the key pools and fluxes of the hydrologic cycle. This product targets an 8th grade audience and is designeAuthorsHayley R. Corson-Dosch, Cee S. Nell, Rachel E. Volentine, Althea A. Archer, Ellen Bechtel, Jennifer L. Bruce, Nicole Felts, Tara A.

The Real Time Flood Alert System is a web-based computer program, developed as a data integration tool, and designed to increase the ability of emergency managers to rapidly and accurately predict flooding conditions of streams in Puerto Rico. The system includes software and a relational database to determine the spatial and temporal distribution of rainfall, water levels in streams and reservoirAuthorsDianne Lopez-TrujilloReal-time rainfall-runoff model of the Carraizo-reservoir basin in Puerto Rico
