| An increasing number of basins in different latitudes face serious problem of water overexploitation. Establishing the limits until which it is possible to make sustainable use of surface water resources is transcendental both for basins that are starting their development of hydraulic infrastructure and for those that are already developed. It is for this reason that the Mexican Secretariat of the Environment and Natural Resources emitted the Official Mexican Norm NOM-011-CNA-2000, which establishes the procedure to determine the availability of national waters. The objective of this work is to analyze the effect of time scale in the determination of the availability of surface waters in basins through the method established by the Mexican norm. The basin used for the development of this work was the mediumupper basin of the Florido River, in the northern Mexican state of Chihuahua. The basin was divided into Upper Sub-Basin (U-SB1), which lacks infrastructure for water use, and Middle Sub-Basin (M-SB2), in which Irrigation District 103 and its well-developed infrastructure are located. The availability of surface water in both sub-basins was determined at annual and monthly time scales. The downstream flow determined in regulatory or water availability terms for sub-basin U-SB1 was 104 Mm3 both for the annual and monthly time scales. The downstream flow determined in terms of water availability for subbasin M-SB2 was 17.7 Mm3 at the annual scale and 41.3 Mm3 at the monthly scale. | |
