Groundwater modelling in aquifers with highly karstic and heterogeneous characteristics (KHC) in Palestine, 2002, Froukh Lj,
Groundwater modelling is hindered by the lack of adequate information about the groundwater system and hence the need for an interactive and efficient system for data preparation and results analysis. Such a lack of information usually necessitates the use of tedious iterative methodology within a sensitivity analysis scheme. The heterogeneous aquifer systems complicate the issue since more data is required to simulate the system. This study demonstrates the integrated approach to bridge the gap between data handling and modelling. The karst cretaceous aquifer system (complex aquifer system) of the Eastern Basin in the West Bank is used to illustrate this approach. The groundwater modelling approach integrates the outputs from different programs for data preparation and analysis. These include (1) Groundwater Database (GWW) (2) Geographic Information System (GIS) (3) Groundwater Modelling System (GMS). In addition, the paper will summarize the data collection efforts, problems faced and experience gained working with heterogeneous media. This involves linking the results from various field investigations for groundwater development programs in the West Bank

Modified DRASTIC assessment for intrinsic vulnerability mapping of karst aquifers: a case study , 2011, Mimi Ziad A. , Mahmoud Nidal, Abu Madi Maher

Groundwater in karstic aquifers can be dangerously sensitive to contamination. In this paper, DRASTIC assessment was modified and applied, for the first time, to address the intrinsic vulnerability for karst aquifers. The theoretical weights of two of DRASTIC’s parameters (aquifer media and hydraulic conductivity) were modified through sensitivity analysis. Two tests of sensitivity analyses were carried out: the map removal and the single parameter sensitivity analyses. The modified assessment was applied for the karst aquifers underlying Ramallah District (Palestine) as a case study. The aquifer vulnerability map indicated that the case study area is under low, moderate and high vulnerability of groundwater to contamination. The vulnerability index can assist in the implementation of groundwater management strategies to prevent degradation of groundwater quality. The modified DRASTIC assessment has proven to be effective because it is relatively straightforward, use data that are commonly available or estimated and produces an end product that is easily interpreted.
