“…Focused recharge is known to be an important process of recharge generation in regions with heterogeneous subsurface characteristics (4, 28) and its strong impact on overall groundwater recharge amounts has been shown in several studies at the catchment scale (29)(30)(31). Our recharge sensitivity analysis reveals that accounting for this process and the variability of soil storages at a much larger spatial scale results in different recharge sensitivities compared with a homogeneous subsurface representation that does not consider focused recharge.…”

Our environment is heterogeneous. In hydrological sciences, the heterogeneity of subsurface properties, such as hydraulic conductivities or porosities, exerts an important control on water balance. This notably includes groundwater recharge, which is an important variable for efficient and sustainable groundwater resources management. Current large-scale hydrological models do not adequately consider this subsurface heterogeneity. Here we show that regions with strong subsurface heterogeneity have enhanced present and future recharge rates due to a different sensitivity of recharge to climate variability compared with regions with homogeneous subsurface properties. Our study domain comprises the carbonate rock regions of Europe, Northern Africa, and the Middle East, which cover ∼25% of the total land area. We compare the simulations of two large-scale hydrological models, one of them accounting for subsurface heterogeneity. Carbonate rock regions strongly exhibit "karstification," which is known to produce particularly strong subsurface heterogeneity. Aquifers from these regions contribute up to half of the drinking water supply for some European countries. Our results suggest that water management for these regions cannot rely on most of the presently available projections of groundwater recharge because spatially variable storages and spatial concentration of recharge result in actual recharge rates that are up to four times larger for present conditions and changes up to five times larger for potential future conditions than previously estimated. These differences in recharge rates for strongly heterogeneous regions suggest a need for groundwater management strategies that are adapted to the fast transit of water from the surface to the aquifers.groundwater recharge | subsurface heterogeneity | water resources | climate variability | climate change

“…Recharge of karst systems (and all aquifer systems in general) may be autogenic when it occurs directly from precipitation over the karst aquifer area (diffuse and concentrated infiltration), or allogenic when originated from streambed infiltration from upstream surface runoff in low permeable rocks into sinking or losing streams (Andreo et al, 2008;Taylor and Greene, 2008;Janza, 2010).…”

Abstract. The water balance of the mesocenozoic aquifers of the Algarve, in the south of Portugal has traditionally been estimated considering only direct ("autogenic") recharge from rainfall occurring in the area of the aquifers. Little importance has been attributed to so-called allogenic recharge, originating from streambed infiltration from runoff generated outside the aquifers, particularly in the Palaeozoic rocks to the north where runoff is high. The Querença-Silves (QS) aquifer is the most important aquifer of the region both for irrigation and public water supply. Several important and sensitive surface/groundwater ecotones and associated groundwater dependent ecosystems exist at the springs of the natural discharge areas of the aquifer system. A numerical flow model has been in constant development over the last few years and currently is able to reproduce the aquifer's responses to estimated direct recharge and abstraction for the years 2001-2010. However, recharge calculations for the model do not take into account allogenic recharge infiltration along influent reaches of streams. The quantification of allogenic recharge may further improve the assessment of water availability and exploitation risks. In this paper an attempt is made to quantify the average annual contribution of allogenic recharge to the QS aquifer, based on monitoring data of the principal water courses that cross the aquifer system. Significant uncertainties related to surface runoff generated within the aquifer area, as well as areal recharge were identified and the consequences for the optimization of spatial distribution of transmissivity in the groundwater flow model are also addressed.

“…The recharge rate is one of the basic parameters in consumption management and maintenance of these resources (Hartmann et al 2014). Recharge of an aquifer can be defined as the annual average volume that is usually in the form of resources or the average annual input as well as a percentage of precipitation commonly known as 'rate of recharge' or 'effective infiltration' (Mejías et al 2012;Andreo et al 2008).…”

“…Methods based on GIS, which utilize geographic attributes of parameters such as geology, altitude, slope, soil type, vegetation and mean annual precipitation, are often applied in order to determine the spatio-temporal distribution of recharge of karst formation (Andreo et al 2008;Allocca et al 2014). In this regard, calculation of recharge through conventional methods (evapotranspiration, natural, chemical or synthetic isotopic tracing, and calculation of precipitation against time) or through numerical models has limitations such as lack of access to accurate and periodic data (Radulovic et al 2012).…”

“…These methods make the calculation of groundwater recharge easier through a quicker and more concise analysis (Peña & Arcos 2004). In this context and in order to overcome the problems and achieve a more realistic estimation of recharge in karst environment, based on indigenous variables of the aquifer, the Geological Survey of Spain (IGME) has used a new technique called APLIS (Altitude, Pendant or Slope, Lithology, Infiltration, Soil) (Andreo et al 2008). Comparatively better than previous models, this method does not require accurate and periodic data and therefore significantly decreases the costs of water resource management (López-Geta et al 2004).…”

Zato raziskava z uporabo metode APLIS, ki temelji na GIS, raziskuje vodonosnike v provinci Severni Horasan v Iranu. Pri tem smo upoštevali več pomembnih hidrogeoloških parametrov, ki vplivajo na napajanje vodonosnika, vključno z nadmorsko višino, naklonom, litologijo, tipom tal in infiltracijo. Za vsakega od parametrov smo pripravili informacije v ustreznih oblikah. Po obdelavi in integraciji podatkov smo izračunali hitrost polnjenja vodonosnika. Različne regije smo ustrezno ovrednotili. Rezultati kažejo, da se v kraških formacijah Severnega Horasana letne povprečne vrednosti v 30-letnem časovnem obdobju gibljejo med 103 mm in 362 mm, s povprečno vrednostjo 192 mm. Najmanjše, najvišje in povprečne stopnje polnjenja vodonosnika v študijskem območju so 42-, 73-in 54-odstotne. Tudi potencial polnjenja vodonosnika je v 83-odstotnih kraških formacij ocenjen kot zmeren, za preostale predele je ocenjen kot visok. Območja z nizkim potencialom polnjenja so povezana z nižje ležečimi zakraselimi apnenci in dolomiti, višje ležeča območja predstavljajo apnenci in dolomiti z višjim potencialom polnjenja. Ključne besede: upravljanje podzemnih vodnih virov, napajanje, APLIS, GIS, kras, Severni Horasan. In order to optimize consumption, maintenance and control of underground water, an estimation of the groundwater recharge is highly important. Therefore, this research investigates the aquifers in North Khorasan province using APLIS (Applied Physics Laboratory Ice Station) based on a GIS. For this purpose, several significant hydrogeological parameters affecting groundwater recharge including altitude, slope, lithology, soil type and infiltration are considered. Therefore, corresponding layers for these parameters were provided and prioritized. In the end and after integrating the data, the recharge rate was measured qualitatively and different regions were mapped accordingly. The results indicate that the annual average values on a 30-year timescale in karst formations of the North Khorasan vary between 103 mm and 362 mm, with the mean value of 192 mm. Minimum, maximum and mean recharge rates of aquifer in the study area are 42 %, 73 % and 54 %, respectively. Also, aquifer recharge potential in 83 % of the karst formations is moderate while it is high for the remaining. Low recharge regions correlate to lower karst limestone and dolostone areas in the lower altitudes while high recharge regions represent upper karst limestone and dolostone areas, especially in the high altitudes.
