Análise temporal e histórica da distribuição dos reservatórios superficiais no Estado da Paraíba - BR

Abstract

Due to the importance of water for urban supply and agricultural production in the Brazilian Northeast, and especially of the populations living with the various conditions of semi-arid, the Federal Government, in partnership with the states, for many years has invested in the construction of several reservoirs, with the main objective of accumulating water for these and other purposes, for example: There are various dams built under the supervision of the DNOCS and / or state agencies, such as SUPLAN and infrastructure secretaries and water resources. Against this situation and the importance of the theme, the present study aimed to identify the capacities of the projected dams and the distribution and current situation of the dams in the public domain of the State of Paraíba. For this, the mapping of the location of these works was done, and showed an overview about the accumulation capacity of the main reservoirs. Based on data collected from several state agencies that responsible for these works, it can be concluded that the State of Paraíba has a large number of reservoirs and capacities of accumulated volumes between 16,000 and 591,646,222 cubic meters. One of the important conclusions drawn at the time of this survey is the fact that the Paraiba reservoirs monitored by the AESA are well below the projected accumulation capacity. Currently with an average of around 20.55%, which demonstrates the water shortage in the State.
