Simulação da cobrança de água subterrânea na bacia do rio Paraíba-PB.

Abstract

The overexploitation of groundwater has been identified as one of the serious environmental problems in the world today. The fact is that this type of water has been used in several human activities such as agriculture. The danger of this action is in the persistence of old paradigms about the participation of such water in the hydrological cycle, which have separated from the groundwater surface, which can not be conceivable, since there is a close link between them, which justifies the need for integrated management, based in the hydrogeological knowledge of the areas where these types of water occur simultaneously, in addition to applying the principles and instruments of National policy of water resources(Law 9.433/97). In that sense, this paper aims to propose two models (revenue collection and economic) to support decision making in the implementation of the instrument of charging for the use of groundwater resources in the coastal sedimentary basin Hydrographic Region of the Lower Course of the River Paraiba. To achieve these objectives data were collected hydrogeological, climatic, socioeconomic and uses of water resources throughout the area. Were made comparative analysis of results with revenue collection and economic models, as well as verification of possible impacts of charging on the various uses.
