Abstract: We proposed the use of The ArcHydro data model as the data repository to calculate the surface water amount in a basin. The Arc Hydro Data Model is considered as a geographic database containing a GIS representation of a Hydrological Information System under a case-specific database design. It includes a set of tools providing raster, vector, and time series functionality like rain, temperature, evaporation, uses of water. The estimation of the available surface water is based on the Official Mexican Norm NOM-011-CNA-2000, “Water resource conservation” that uses the continuity equation. Water distribution at the Zirahuen river basin (282.61 km2) is: it generates a natural draining by own river basin of 40.22 hm3, returns 1.45 hm3, for consumptive use volume is 2.99 hm3 and the draining water is 38.69 hm3 and finally the surface water availability is 0 hm3.
