Karst aquifers in the Mediterranean region are crucial for water supply and agriculture but increasingly threatened by climate change overexploitation. The Jebel Zaghouan aquifer, historically significant supplying Carthage Tunis, serves as focus of this study, which aims to evaluate its availability, quality, vulnerability ensure long-term sustainability. To achieve this, various methods were employed, including APLIS COP recharge assessment mapping, SPEI SGI drought indices, stable radioactive isotope analysis. findings revealed severe groundwater depletion, primarily caused overexploitation linked urban expansion. Minimal was observed, even during wet periods. analysis indicated moderate infiltration rates, consistent with prior reservoir models MEDKAM map. Isotopic highlighted from Atlantic mixed rainfall, while Tritium Carbon-14 dating showed a mix ancient recent water, emphasizing aquifer’s complex hydrodynamics. mapping classified 80% area moderately vulnerable. Monitoring nitrate levels fluctuations, peaks years at Sidi Medien Spring, necessitating control measures safeguard quality amid agricultural activities. This study provides valuable insights into dynamics, guiding sustainable management preservation efforts.

Global urbanization has led to the overexploitation and pollution of groundwater resources, restricting sustainable construction development cities. Groundwater environmental carrying capacity (GW-ECC) refers maximum total amount pollutants that can be accommodated by a given system within certain time period under specified goals. To better understand changes in GW-ECC context rapid urbanization, this study built model urban driven multiple factors. Taking area Zhengzhou as an example, rainfall infiltration riverside seepage were calculated considering change impervious over past 20 years. The Mann–Kendall rank test was used evaluate varying trends two factors process. Based on this, current year calculated, different regulatory schemes after 10 years evaluated. results showed constructed could accurately simulate system. With acceleration recharges precipitation, rivers tend decline. ammonia nitrogen exhibited overall upward trend. By end 2030, is expected reach 1964.5 t. Changes resources caused precipitation extraction main driving variations GW-ECC. In areas with mature measures such increasing recharge reducing are more effective improving

In the last decades, climate change has led to increasingly frequent drought events within Mediterranean area, creating an urgent need of a more sustainable management groundwater resources exploited for drinking and agricultural purposes. One most challenging issues is provide reliable simulations forecasts karst spring discharges, whose reduced information, as well hydrological processes involving their feeding aquifers, often big issue water service managers researchers. order plan resource exploitation that could face future shortages, availability should be assessed by continuously monitoring discharge during year, using collected data better understand past behaviour and, possibly, forecast one in case severe droughts. The aim this paper factors govern different patterns according rainfall inputs present model, based on artificial neural network (ANN) training cross-correlation analyses, evaluate some Umbria region (Central Italy). model used fully connected (FCNN) been both filling gaps time series simulating response six springs seasonal from 20-year continuous daily record, provided Regional Environmental Protection Agency (ARPA) region.

A time series approach was proposed to improve the knowledge of a wide coastal karst aquifer. The combines decomposition, trend, autocorrelation and cross-correlation analyses using both daily monthly temperature, rainfall piezometric data with different temporal characteristics. merges shorter complete (2007-2011) long-lasting times (1965-2011) relevant gaps. applied Salento aquifer (Southern Italy) enhance comprehensive statistical tools variables in assessing hydrodynamic properties systems. Results underscore approach's effectiveness describing aquifer, unveiling significant inertia investigated system concerning transmissivity substantial storage capacity. Differences memory effect response between emphasise intricate nature examined influence dataset quality. declining trend observed as an climate change anthropic pressure.

Nowadays the phenomenon of global warming is unequivocal, as confirmed by latest reports IPCC and studies climate-change impacts on ecosystems, economy, populations. The effect climate change groundwater a very relevant task especially for regions dependent chiefly availability, southern Italy. In such territorial framework, to achieve detailed hydro-climatological characterization, an Ensemble 15 RCMs (E15) derived from EURO-CORDEX project was analyzed considering two Representative Concentration Pathways (RCP4.5 RCP8.5). E15 calibrated over period (1950–1996) statistical comparison with data observed regional meteorological network managed former National Hydrological Service (SIMN), Department Naples. effects air temperature (T), precipitation (P) and, consequently, actual evapotranspiration (ETR) effective Pe (P – ETR) were until 2100. latter considered proxy recharge principal aquifer systems, represented karst aquifers. As result, it found that basically able reproduce annual (OBSP) mean (OBST), being characterized similar frequency distribution. Accordingly, inferential approach performed calibrating (E15P) (E15T) based compensation difference OBSP (+ 7%) OBST (− 16%). projects reduction in increase under both RCPs, divergence point between scenarios occurring about 2040. shows declining trends RCP scenarios, reaching decrease 11-yrs moving average down − 20%, RCP4.5, 50%, RCP8.5, even if inter-annual fluctuations.
