“…Kessler (1965) found values ranging from 7 to 70 % in Hungary. In Greece, Soulios (1984) arrived at a mean value of 50 %. In Italy, Boni et al (1982, in Alloca et al 2014 found values of up to 70 % for some karst aquifers in the central Apennines, and Alloca et al (2014) reported values from 35 to 55 % in the southern Apennines.…”

Review on groundwater recharge in carbonate aquifers from SW Mediterranean (Betic Cordillera, S Spain)

et al. 2015

This paper presents a review of groundwater recharge assessment in some 50 carbonate aquifers of the extreme SW Mediterranean domain (Betic Cordillera, southern Spain), an area highly vulnerable to climate change. The selected aquifers represent a broad range of meteorological and geological conditions, and consequently results can be expanded eastward to other Mediterranean aquifers. The methods most commonly applied for recharge assessment over the past 20 years are aquifer water budget and soil water balance. While these methods support the first steps in groundwater management in Spain, precision in quantification requires other methods to be incorporated. They include chloride mass balance, diverse lumped model codes and empirical methods such as APLIS. In eastern areas of the Betic Cordillera, where semiarid conditions prevail, lumped and distributed models for recharge assessment and calibration are based on the time series of water table data. The mean annual rainfall, recharge and coefficient infiltration (as percentage of rainfall) are, respectively, 648, 262 mm/year and 38 %. A high correlation was observed between annual rainfall and annual recharge in all the studied aquifers. However, the infiltration coefficient can vary substantially even with the same annual rainfall recharge. This reflects significant differences in the degree of surface karstification and the development of the vegetal cover-soil-epikarst system in the carbonate aquifers of the Betic Cordillera. The results of this work may serve to improve the assessment and management of renewable water resources in western Mediterranean carbonate aquifers. The findings are moreover useful for future comparisons involving recharge assessments under different scenarios of climate change and changes in land use.

“…In karst aquifers, the EIC is controlled by several factors, among which the composition of carbonate rocks, fracturing degree, development of epikarst and deeper karst processes, slope steepness, land use and covering soil type can be basically recognized. Several estimations and applications of EIC for calcareous karst aquifers were carried out in Hungary (Kessler, 1965), Greece (Burdon, 1965;Soulios, 1984), France (Drogue, 1971) and Croatia (Vilimonovic, 1965;Bonacci, 2001), at the annual timescale, finding values ranging from 35 to 76 %, with a mean value around 51 %. Finally, for other non-European countries, a value of 27 % was assessed for the dolomitic basin of Tennesee (Sodeman and Tysinger, 1965).…”

Abstract.To assess the mean annual groundwater recharge of the karst aquifers in the southern Apennines (Italy), the estimation of the mean annual groundwater recharge coefficient (AGRC) was conducted by means of an integrated approach based on hydrogeological, hydrological, geomorphological, land use and soil cover analyses. Starting from the hydrological budget equation, the coefficient was conceived as the ratio between the net groundwater outflow and the precipitation minus actual evapotranspiration (P − ETR) for a karst aquifer. A large part of the southern Apennines, which is covered by a meteorological network containing 40 principal karst aquifers, was studied. Using precipitation and air temperature time series gathered through monitoring stations operating in the period 1926-2012, the mean annual P − ETR was estimated, and its distribution was modelled at a regional scale by considering the orographic barrier and rain shadow effects of the Apennine chain, as well as the altitudinal control. Four sample karst aquifers with available long spring discharge time series were identified for estimating the AGRC. The resulting values were correlated with other parameters that control groundwater recharge, such as the extension of outcropping karst rocks, morphological settings, land use and covering soil type. A multiple linear regression between the AGRC, lithology and the summit plateau and endorheic areas was found. This empirical model was used to assess the AGRC and mean annual groundwater recharge in other regional karst aquifers. The coefficient was calculated as ranging between 50 and 79 %, thus being comparable with other similar estimations carried out for karst aquifers of European and Mediterranean countries. The mean annual groundwater recharge for karst aquifers of the southern Apennines was assessed by these characterizations and validated by a comparison with available groundwater outflow measurements.These results represent a deeper understanding of an aspect of groundwater hydrology in karst aquifers which is fundamental for the formulation of appropriate management models of groundwater resources at a regional scale, also taking into account mitigation strategies for climate change impacts. Finally, the proposed hydrological characterizations are also supposed to be useful for the assessment of mean annual runoff over carbonate mountains, which is another important topic concerning water management in the southern Apennines.

Quantification of recharge is a fundamental issue in evaluation and management of karst water resources. Recharge coefficient (RC), which is the ratio of aquifer recharged water (VR) to the total precipitation, has been widely used for recharge estimation in karst catchments. Though the RC definition is straightforward, in practice, its application on a fixed short time scale (e.g., monthly or annual) is challenging, because of the problems in determination of change in groundwater storage (DVS) that is included in VR. Some researchers have neglected DVS, estimated VR as equal to the net aquifer outflows; hence they have over-or under-estimated the RC, ignoring the aquifer's antecedent storage condition. In this study, a new method is proposed to estimate the actual event VR, and consequently, the event-based RC, utilizing the MRC displacement method of Kavousi and Raeisi (2015). Applying the method, VR due to a specific event or a combination of events during a hydrological year can be directly estimated by decomposition of the observed hydrograph to the individual hydrographs induced by different events. The method is applicable for karst aquifers with no-flow boundaries, draining by a spring. The calculated event VR takes DVS into account, enabling an accurate event-based RC estimation. The method was applied to the Sheshpeer karst aquifer in Iran. The estimated RCs reasonably matched up to the catchment properties and former field studies. Results showed that the annual RCs would be underestimated if the DVS was neglected, because DVS was positive during the study period.
