Abstract Water is scarce in the semi-arid to arid region around the Dead Sea where water supply mostly relies on restricted groundwater resources. Because of population increase the regional groundwater body is exposed to additional stress, which also results in a continuous decrease of the Dead Sea level. As the interdependency between water demand from population increase and the decrease in groundwater availability will proceed over the next years, the stressed water supply situation appears to proceed also and possibly worsens unless sustainable changes are introduced. These changes however, can only be suggested if the hydrogeological situation in the tectonically complex region is fully understood. A number of simplified models of the Judea Group aquifer have been formulated and employed using a two-dimensional (one horizontal layered) numerical simulation of groundwater flow (Baida et al. 1978; Goldschtoff & Shachnai, 1980; Guttman, 2000; Laronne Ben-Itzhak & Gvirtzmann, 2005). However, all previous approaches focused only on a limited area of the Judea Group aquifer. We developed a high resolution regional groundwater flow model for the entire western basin of the Dead Sea. Whereas the structural model could be defined using a large geological dataset, the challenge was to generate the groundwater flow model with only limited well data. With the help of the scientific software OpenGeoSys (OGS) the challenge was reliably solved resulting in a simulation of the hydraulic characteristics (hydraulic conductivity and hydraulic head) of the cretaceous aquifer system, which was calibrated using PEST.
