Numerical Tools In The Inquiry And Remediation Of Contaminated Areas

In area contaminated for hydro-carbons, the migration of the contaminantes and the efficiency of the bombardment system depend on the litolgica heterogeneidade of the water-bearing place. In such a way, the agreement of the heterogeneidade and the hydraulical properties that characterize this water-bearing one is essential for the otimizao and the improvement of remediation processes. With sights to characterize the hidrogeolgico context of the place it is interesting to elaborate conceptual the hidrogeolgico model, by means of the integration of the data proceeding from inquiry techniques? geophysical methods, monitoramento of piezomtricos levels of monitoramento wells, geologic descriptions and grain sized analyses, getting itself, thus, of local flow of the value and the distribution and the dynamics litotipos water-bearing its of hydraulical condutividade. Face to the vast amount of generated data of numerous sources in a variety of formats and to the advances of the tools of management of ambient data of the numerical tools in the inquiry and Remediation of areas contaminated for hydro-carbons it follows a new trend for the formularization of conceptual a hidrogeolgico model from the integration of the information acquired in the bibliographical survey of geologic data and hidrogeolgicos regional places and; monitoramento of level d? water, from the accompaniment of the hydraulical load in monitoramento wells; geologic characterization of subsurface, hydraulical characterization of the water-bearing one. Due to centralization of the information and the tools integrated to the system of management of data, the numerical simulation already part of a conceptual model, not needing to inform to the software of the model the hidrogeolgicas characterizations. The accomplishment of numerical simulation of flows in permanent regimen, using the Visual software Modflow that uses the methods of finite differences to test the model conceptual conceived. The results gotten for the correlation enter the values of hydraulical loads measures and simulated they allow to verify the consistency of the conceptual model.
