Análise temporal da estrutura de dependência espacial da salinidade em aluvião no semi-árido.

Abstract

The study of spatial dependence of hydrologic variables related to groundwater has a great importance for an efficient management of the water resources. The water must be managed in order to ensure the preservation of its quality, and the maintenance of the supply. In face of the relevance of groundwater in alluvial valleys in the northeast semi-arid region of Brazil, it is of utmost importance its systematic monitoring of salinity and groundwater level. The present work analyzes the existence of spatial dependence of the groundwater electrical conductivity. It has been verified that this dependence presents similar behavior throughout different climate conditions, for the period from December 2004 to November 2005.
