EVALUACIÓN DE LA DISPONIBILIDAD DE ÁGUA EN LA CUENCA VENTO APLICANDO MINERÍA DE DATOS

Evaluation of the water availability in the Vento basin applying data mining

Abstract

The water availability is decreasing mainly due to climate, environmental and economic factors, while the demand increases with the development and life standard improvement. The water integral management is key to an adequate balance. Havana isn’t outside this problematic. Supplied mainly by groundwater, it is exposed to seasonal variations in water supply, with a deficit that has exceed 1000 l/s, directly and indirectly affecting the supply to more than 250000 inhabitants. The study proposes a model to classify the water availability in the aquifer for urban supply, applying tools of data mining to the records taken with a daily frequency in a period o five years from 2016 to 2020, which main variables are: precipitation, aquifer levels, withdrawals, and discharge volume, among others. The classification model obtained has a success percent of 98%, constituting a tool for evaluating the resources available to specialists and decision makers, being the basis to identify the occurrence of operational drought and to structure a plan to reduce the risk of urban deficiencies in the event of shortage and/or drought.
