“…The springs that discharge the large regional aquifers [such as the Yarqon Springs in coastal Israel, historically discharging about 227 million cubic meters per year (Dafny et al 2010)] have longer memory duration than the small perched springs discussed above. Therefore, these 'regional' springs may have served their communities for longer and perhaps as a regional backup during short droughts to the rest of population.…”

In ancient times human activities were tightly related and sensitive to rainfall amounts and seasonal distribution. East Mediterranean settlements were concentrated around numerous small to large springs, such as the Judean Mountains area. The goals of this study were to determine (a) the sensitivity of total discharge, recession curve, and response time of such springs to annual precipitation patterns, and (b) how spring hydrology responds to series of drought or wet years and to transitions from drought to normal and/or wet episodes (and vice versa). These goals were achieved by setting a finite-element hydro-geological flow model for selected perched springs that characterize the numerous springs throughout the carbonate karst terrain in the Judean Mountains. In addition, we estimated the effect of proposed regional past climate changes on the springs; in so doing, we transfer climate change to community size, livelihood and economic strength that were highly dependent on agricultural productivity. The results of the hydro-geological model revealed that these mountainous communities had the potential to prosper during historically wetter episodes and were probably adapted to short-term variability in annual rainfall. However, moderate to extreme droughts lasting only a few years could have led to a partial or even total abandonment of the springs as focal sites of intensive agricultural production. Spring drying eliminated the primary cause for the location of settlement. This occurred simultaneously in numerous settlements around the mountains of the southern Levant and therefore, must have caused dramatic economic and societal changes in the entire region, perhaps even resonating afar.

“…These intricacies heavily influences the surface water-groundwater interactions, particularly during flooding events [9,10]. The study area is located within the recharge area of the fractured carbonate Western Mountain aquifer (Yarkon-Taninim) [27]. The aquifer extends from south of the Carmel Mountains, in the north, to the Sinai Desert in the south, and from the Judea and Samaria Mountains in the east, to the Mediterranean coastline in the west.…”

“…The local geology of the study area is composed of the carbonated Judea group in which epikarst features are common, and contain a weathered zone of enhanced porosity near the surface or the soil/bedrock contact [28,29]. The groundwater level is deep, ranging from a few tens of meters to two hundred meters below ground level [27,30,31]. The general flow direction is westward.…”

“…In total, during this hydrological year, 0.99 Mm 3 (million m 3 ), 1.11 Mm 3 , and 0.43 Mm 3 of runoff water flowed into EK4, Sataf, and Matash sub-basins, respectively. The study area is located within the recharge area of the fractured carbonate Western Mountain aquifer (Yarkon-Taninim) [27]. The aquifer extends from south of the Carmel Mountains, in the north, to the Sinai Desert in the south, and from the Judea and Samaria Mountains in the east, to the Mediterranean coastline in the west.…”

Sustainable groundwater production from karst aquifers is primarily dictated by its recharge rate. Therefore, it is essential to accurately quantify annual groundwater recharge in order to limit overexploitation and to evaluate artificial methods for groundwater enrichment. Infiltration during erratic flood events in karst basins may substantially contribute to aquifer recharge. However, the complicated nature of karst systems, which are characterized in part by multiple springs, sinkholes, and losing/gaining streams, impede accurate quantification of the actual contribution of flood waters to groundwater recharge. In this study, we aim to quantify the proportion of groundwater recharge accrued during runoff events in a karst aquifer. The role of karst conduits on flash flood infiltration was examined during four flood and controlled runoff events in the Soreq creek near Jerusalem, Israel. We distinguished between direct infiltration, percolation through karst conduits, and diffuse infiltration-the latter of which is most affected by evapotranspiration. A water balance was calculated for the 2014/15 hydrological year using the Hydrologic Engineering Center-Hydrologic Modelling System (HEC-HMS). Simulations show that 6.8 to 19.2% of the annual recharge volume was added to the aquifer from infiltration of runoff losses along the creek through the karst system.

“…It should be realized that by just using last century's schemes no longer solves challenges related to today's groundwater situation (Zaisheng et al, 2006). In recent years, groundwater numerical simulation models like Feflow which is based on finite element method have been widely applied to groundwater dynamics simulation due to its appealing features such as visualization, interaction and diversified solving methods (Yang and Radulescu, 2006;Russo and Civita, 2009;Peleg and Gvirtzman, 2010;Dafny et al, 2010).…”
