A hydrogeological-based multi-criteria method for assessing the vulnerability of coastal aquifers to saltwater intrusion

摘要: The interaction between salt and fresh water is an important issue in coastal aquifer management there are numerous methods used to assess the vulnerability of systems saltwater intrusion. aim present study was a hydrogeological-based method that could be applied all their To achieve this goal, five criteria, namely GWQISI (I), which shows magnitude Intrusion, groundwater level (L), existing Distance shore (D), recharge (R) saturated thickness (T) were develop novel multi-criteria decision index, ILDRT. digital integration various weights rates assigned criteria carried out based on literature, expert knowledge, overlay indexing standards. proposed approach evaluated Iran’s Malekan intrusion from Lake Urmia. Results showed index most significantly influenced by R sensitivity analysis using map removal accompanied single parameter method. Based ILDRT results, about 22, 49 29% total area zones very low, low moderate intrusion, respectively.
