Research interests and academic activities Groundwater hydrology & soil-water engineering Water management & water security in complex aquifer systems Main research activities are associated with quantitative assessment of groundwater flow systems and sources of recharge in complex arid basins with puzzling geology and scarce hydrological information. For complex hydrological systems, Adar developed the Mixing Cell Model (MCM) approach utilizing hydrochemistry and environmental isotopes in water and mass balance equations coupled with a hydrological flow model. It is aimed for assessing groundwater flow patterns in multiple-aquifer systems. Prof. Eilon Adar developed the Mixing Cell MCMsf model for a steady flow system based on quadratic programming. It has been further developed into a user-friendly code for the definition of groundwater flow patterns in multiple-aquifer flow systems by environmental and/or anthropogenic tracers. The model has been applied in several hydrological basins worldwide, from the Kalahari Desert (Namibia), Jezreel and Bessor basins (Israel), to the Ili basin in Kazakhstan. A novel mixing cells approach based on linear programming was developed for transient flow systems. The MCMusf model has been applied in the Arava aquifer of Jordan and Israel in order to define the relative groundwater contribution from Jordanian and Israeli sources. Among other research activities, are the initiation and/or involvement in the investigation of (1) the role of water reservoirs and shallow groundwater on top-soil salinization in the Jezreel Valley; (2) the effects of forestation over sand-dune terrain on local groundwater reservoirs; (3) the dynamics of flow and pollutant transport in a fractured chalk aquitard (low permeable yet fractured formation) in the vicinity of the Ramat Hovav Industrial Park; (4) identification and quantification of pollutant sources into ephemeral rivers from various basins; (5) the effect of industrial effluents on the hydraulic properties of a fractured chalk aquitard; (6) identification of irregular salinization processes in the Coastal Aquifer of Israel; (7) salinization and deterioration of topsoil water quality due to anthropogenic activities; (8) soil and groundwater contamination in the coastal aquifer of Israel by organic industrial pollutants (9) migration, dilution and bio-chemical evolution of dissolved explosive substances in multi-aquifers system; (10) hydrology and water management of transboundary water resources in Israel and the Middle East; and (11) The water balance and flow pattern of deep seated groundwater in the upper Jordan Valley (Hula Valley), Israel;(12) Identification of groundwater sources, quantification of groundwater fluxes, and the hydraulic connectivity between sub-aquifer units in the Arava Valley (Israel & Jordan); (13) A reevaluation of the groundwater flow pathways in the Nubian sandstone aquifer in Sinai and the Negev with hydrochemistry, environmental stable isotopes, and the calculation of groundwater age using radio-carbon and krypton isotopes.
