Introduction The modeling of water resources has become an important issue for decision holders and water users. By modeling, we can diagnose the resource, visualize future scenarios and establish strategies for optimization. The WRAP model need to be fed with certain files: naturalized flow, evaporation and watershed parameters (drainage area, curve number and mean annual precipitation ).

Objectives Obtain the watershed parameters (drainage area, curve number and mean annual precipitation ) for the El Fuerte Basin Upload the watershed parameters in the El Fuerte Water Reliability Model for Hydropower Generation Display the reliability output in the Geographic Information System (GIS)

El Fuerte Basin

Area of 34,597 sq Km 3 Reservoirs 2 Irrigation Districts Luis Donaldo Colosio “Huites” (4568 MCM) Miguel Hidalgo “El Fuerte” (4069 MCM) Josefa Ortiz de Dominguez (590 MCM) ID 076 Valle del Carrizo (43,259 ha) ID 075 Valle del Fuerte (201,844 ha) Characteristics

Data Sources The DEM used in this project was provided by the Mexican mapping agency INEGI. The Mexican climatologic database, ERIC, was used to locate the precipitation gages and to build the mean annual precipitation raster. Also, the Mexican hydrologic database, BANDAS, were used to locate the streamflow gages.

WRAP Hydro Process

Preprocessing -To set the Geodatabase -To obtain and give format the necessary feature classes -To obtain the rasters

Watershed Parameterization The watershed parameters were obtained for the El Fuerte Basin through the process described in the final parameter processing section of the WRAP Hydro report by Gopalan and Whitaker (2003); and the Section 7 WRAPHydro Process of the tutorial by Patino (2005).

Conclusions

23 sets of drainage area and mean annual precipitation parameters were obtained for the El Fuerte Basin. The average curve number parameters were not obtained due to the lack of information. The WRMHG can be extended from 8 to 24 control points by using the geodatabase. The outputs of the WRMHG were displayed in the Geodatabase. Further research is needed in the curve number raster, and in the strict representation of the basin
