A model to simulate recharge processes of karst massifs

Abstract: The recharge processes have been evaluated for two karst massifs of southern Italy, the Mt Terminio and Mt Cervialto, characterized by wide endorheic areas. The annual mean recharge has been estimated by Geographic Information System (GIS) tools, from regression of annual mean values of different ground-elevated rain gauges and thermometers. The recharge has been distinguished for endorheic areas and the other areas of spring catchment, and the ratio between the output spring and input rainfall has been also e… Show more

“…How to accurately estimate recharge has remained a persistent challenge and an active research topic in the hydrological science community over many decades (Gee and Hillel, 1988;Scanlon, 2013;Sanford, 2002). It is generally accepted that recharge is correlated with precipitation in some fashions, and many studies adopt the concept of a recharge coefficient (Turkeltaub et al, 2015;Kalbus et al, 2006;Allocca et al, 2014), which is the ratio of the actual recharge to the precipitation, to estimate the recharge (Fiorillo et al, 2015;Allocca et al, 2014). The magnitude of such a recharge coefficient is controlled by a complex interplay of multiple factors such as moisture dynamics in the vadose zone (Schymanski et al, 2008), depth to water table, vegetation, etc., and the recharge coefficient is often regarded as a temporally invariant value at a given location (Fiorillo et al, 2015;Min et al, 2017;Vauclin et al, 1979).…”

Specifically, it is assumed to be primarily controlled by the total precipitation and not too much by the temporal fluctuation of precipitation events (Hickel and Zhang, 2006;Acworth et al, 2016).…”

“…Therefore, it can be noticed and expected that higher recharge in limestone dominated by conduits is due to heavy rainfall. However, it should be mentioned that an accurate and reliable estimation of recharge into karst aquifers is difficult because of their heterogeneous local structures (Bonacci, 2001;De Waele and Parise, 2013;Fiorillo et al, 2015a;Bakalowicz, 2015).…”

“…Both VR and VP are expressed in L 3 or just L averaged over the catchment; thus RC is a dimensionless coefficient, theoretically ranging from 0 (when VR ¼ 0) to 1 (when VR ¼ VP). On a global scale, the reported RCs for karst aquifers cover the whole range, even approaching the two end members (see for example Ashjari and Raeisi, 2006;Allocca et al, 2014;Fiorillo et al, 2015;Martos-Rosillo et al, 2015). RC simply represents the percentage of total precipitation that reached the phreatic zone, reflecting the combined effects of all rechargeprohibiting processes such as water loss through surface runoff or evapotranspiration.…”

“…Instead, determination of RC during a hydrological year, RC Y , or even a shorter time scale (monthly RC M or daily RC D ) is of interest for practical applications (see Bonacci, 2001;Bonacci et al, 2006;Denić-Jukić, 2004, 2009;Jemcov and Petric, 2009;Fiorillo et al, 2015). However, at a short time scale of a year (or a month), the amount of change in groundwater storage is likely not negligible in comparison to the rest of the parameters in the RC calculation.…”
