RIOS, Mauricio José et al. Modeling water availability in the Zirahuén Lake Basin. Tecnol. cienc. agua [online]. 2019, vol.10, n.3, pp.275-288.  Epub Apr 21, 2021. ISSN 2007-2422.  https://doi.org/10.24850/j-tyca-2019-03-11.

In water management, it is essential to know the water availability within the hydrological planning and management units. To improve the knowledge of hydrological cycle variables in the Zirahuén Lake Basin we used the Soil-Water-Balance (SWB) spatiotemporal simulation model supported by the hydrodynamic characteristics of the soil and land cover, together with daily climatological information. Our results showed how land use influences runoff and recharge of aquifers reflecting in water availability estimates, which showed an important setback with an emphasis during the 2009-2015 period. When comparing our results with the official records reported in 2016, we found that the latter figures underestimated the groundwater index (GI) by 14.64% and the relative water availability index (RWAI) by 150% relative to the results of our study. We concluded that, to improve the reliability and management of water in the basin, it is recommend verifying our results by implementing strategies to monitor the quantity, quality, and temporality of water.
