Numerical modeling of Etla Valley aquifer, Oax., Mexico: Evolution and remediation scenarios
Short-term evolution (for 2001, 2005 and 2015) for the shallow aquifer of Etla Valley, Oaxaca, southern Mexico, was simulated based in a 3D hydrological model elaborated from the available geological, geophysical, geochemical, and hydrologic parameters. The numerical simulations were based on Visual...

| description | Short-term evolution (for 2001, 2005 and 2015) for the shallow aquifer of Etla Valley, Oaxaca, southern Mexico, was simulated based in a 3D hydrological model elaborated from the available geological, geophysical, geochemical, and hydrologic parameters. The numerical simulations were based on Visual MODFLOW code. These simulations indicate that, if the actual extraction regime is maintained, the drawdown of the potentiometric surface will get worse to the SE of the study area (i. e. beneath Oaxaca city). The prevailing aquifer flow direction favors the ground water pollution by fertilizers and leakage from the sewage network (dumped to the Atoyac river).According to the numerical simulation, remediation of this situation is possible if the wells located in the neigborhood of Oaxaca City are relocated at the recharge zones (i. e. at the feet from Sierra de Juárez). This remediation scenario will allow a recovery of the drawdown of the potentiometric surface. |
