【摘要】 本文提出了一种划分地下水水源地保护区的方法,首先用地下水模拟系统中的MODFLOW建立研究区的数值模拟模型,获得地下水流场;然后再将水源地划分为3级保护区,用MODPATH确定各保护区的范围;最后根据国家饮用水标准,采用MT3D确定主要污染质在保护区中的可释放阈值,并给出了应用实例。更多还原

【Abstract】 Establishing protection zones for groundwater wellfields is a major method for protecting groundwater quality. In this paper, the conceptual and numerical models of the region of interest were established, and the results obtained by running the MODFLOW and the MODPATH were used to delineate the boundary of the three protection zones of the wellfield in the light of the time criteria. By running the MT3D, the maximum permissible discharge concentration in each zone was obtained.更多还原
