Abstract
Integrating Time Series in Arc Hydro Water Resources Information Systems Track: Water Resources Author(s): Ken Stewart, Jack Hampson, David Maidment, Tim Brink The ideal Water Resources Information System integrates hydrologic spatial data with water data. It should enable the user to look at past, present and future (modeled) conditions. Because Arc Hydro assigns a unique HydroID to each feature of the hydrologic framework and builds relationships between features, it is possible to build data structures and tools that realize that goal. Users can track water moving through the hydrologic framework. Key concepts that underlie this capability have emerged through extensive collaborative work at the South Florida Water Management District. By using lengths and areas from GIS to convert water measurements on the fly to volume and time, data from multiple sources have been integrated. Historic and real-time data from gauges and SCADA systems can be compared with model data, and this data can participate in volumetric estimates of the water as it moves through the hydrologic framework.
