Resumen o descripción

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.
