Lobo Ferreira Ciencias de la Tierra contamination Groundwater flow particle tracking numerical modeling wellhead protection zones Mathematical concepts are used for the development of wellhead protection and zoning methodologies, based on analyticalsolutions and on groundwater flow and particle tracking finite differences. Wellhead protection limits are a function of the localgeology, of the aquifer parameters and the regional hydraulic characteristics of the aquifer, and of the extraction rates or of theproductivity of the aquifer. In the vertical dimension the analysis was performed using an axisymmetric flow model, assuming thatgroundwater flow into the well is radial. The radial axisymmetric mathematical tools were robust and user friendly, facilitating theapplication of the new Portuguese legislation regarding groundwater protection. The methodology is exemplified in two casestudies, one for the coastal aquifer of the Bardez, Goa State, India and the other in Ramalhal, Portugal. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843414 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.43 |
