Avaliação Dos Recursos Hídricos Do Aqüífero Barreiras Na Bacia Do Rio Maxaranguape-Rn.

Abstract: Abstract:The Barreiras aquifer in the inferior course of the Maxaranguape river hydrographic basin, RN, is the main source of water to supply the population, the demands for irrigation and industrial use. The use of groundwater is done, however, without adequate planning, resulting therefore in an inefficiency water use. The objective of this work is to search about the hydrogeologic potentialities of the Barreiras Aquifer and the explotation conductions of the groundwater with sustainability in view of the wa… Show more

“…The aquifer exploitation flow rates are proportional to the saturated thickness, reaching values of 150 m 3 /h in areas of high thickness, especially when associated with sandier lithologies (Lucena et al 2006). Melo et al (2013) performed pumping tests in the area to evaluate parameters such as hydraulic conductivity and transmissivity, reporting average values of 1.0 × 10 -4 and 3.0 × 10 -3 m 2 /s, respectively, for the unconfined aquifer. Silva et al (2014) obtained an average effective porosity of 7.6% from petrophysical studies and image processing of thin sections of the Barreiras Formation.…”

“…Os dois métodos utilizados na avaliação da recarga apresentam incertezas, porém a aplicação da Lei de Darcy em geral fornece valores mais baixos que os outros métodos (MELO et al, 2013;MELO et al, 2014).…”

“…Outro fator delicado a ser considerado é o gradiente hidráulico (I), o qual foi estimado com base em mapas potenciométricos com diferentes possibilidades de caracterização do mesmo. A experiência tem mostrado que a recarga avaliada com aplicação da lei de Darcy fornece em geral valores mais baixos que os outros métodos (MELO et al, 2013).…”
