The systems science approach for the characterization of rainfall in the Mexico's valley

The Mexico City population has grown significantly in recent years; the concentration of population in the city has brought greater demand for water for their daily requirements. The natural aquifers basin of Mexico Valley has been overexploited. There is a considerable imbalance in the amount of water needed for natural recharge of the aquifers of the City; the problem arose because the natural recharging system was obstructed by the construction of infrastructure, roads, buildings and unsustainable policies, until the limits of resilience of the water system. Based on statistics of the area, it shows that the annual rainfall over the basin is far more than needed to meet consumption of the population. However, most of this water is not utilized efficiently, which is not only a serious error, but also helps in increasing the problems of drainage and water extraction from the subsoil of the city. This paper shows the development of a study to characterize the rainfall in the Valley of Mexico, the results would contribute to comprehensively manage the recharge of groundwater with the use of rainwater and the design of a model of behavior recharge and water extraction. The development of this project is funded by the Institute of Science and Technology of the Federal District (ICyTDF), Mexico.
