AGRICULTURAL WATER RESOURCES DECISION SUPPORT SYSTEM AND EVAPOTRANSPIRATION TOOLBOX

摘要

1. The AWARDS - ET Toolbox system developed for the Middle Rio Grande demonstrates a methodology that integrates high resolution WSR-88D 1-hr rainfall estimates, weather station data, atmospheric model forecasts, crop and riparian ET requirements, GIS information, and land usage, with modern computer communication, and Internet technologies for improved water resources management. 2. Daily consumptive use estimates (agriculture + riparian + open water + urban - rain) are accessible on the Web site in tables and plotted graphs (daily, 5-day and 10-day running averages) for the individual river reaches and the total MRGCD plus the Bosque del Apache National Wildlife Refuge. The total daily agriculture, riparian, open water, and urban consumptive use estimates, plus the cumulative rainfall for the defined river reaches, are automatically provided for use in RiverWare, which is the river modeling and water accounting system used by the URGWOM. 3. Pop-up charts and graphs of weather station data, streamflow and river stage, the MRGCD schematic of the gaging system, and the 1-hr WSR-88D Stage III images are updated in near real time. 4. Forecast parameters at 20-km grid resolution from the NCEP Eta model are being used in the ET Toolbox to replace missing weather station data for calculating daily ET, and to make 24-hr and 48-hr river reach consumptive use forecasts. 5. Middle Rio Grande water operations managers who accessed the Web site, often on a daily basis during critical periods, found that the ET Toolbox information was invaluable for their decision making. 6. Reclamation is implementing the AWARDS - ET Toolbox technology in the Upper Columbia Basin using a Reclamation-developed PAA to obtain QPE in place of the NWS RFC Stage III product.
