Karst aquifers provide drinking water for 10% of the world's population, support agriculture, groundwater-dependent activities, and ecosystems. These are characterised by complex groundwater-flow systems, hence, they extremely vulnerable protecting them requires an in-depth understanding systems. Poor data accessibility has limited advances in karst research realistic representation processes large-scale hydrological studies. In this study, we present World Spring hydrograph (WoKaS)...

Abstract. Hydrological models are widely used to characterize, understand and manage hydrosystems. Lumped parameter of particular interest in karst environments given the complexity heterogeneity these systems. There is a multitude lumped modelling approaches, which can make it difficult for manager or researcher choose. We therefore conducted comparison two approaches: artificial neural networks (ANNs) reservoir models. investigate five systems Mediterranean Alpine regions with different...

Abstract Karst groundwater-dependent ecosystems (KGDEs) in the Mediterranean region are important terms of ecosystem services and biodiversity but increasingly under anthropogenic pressures climate-change constraints. For this study, ecohydrological characteristics, threats, protection status 112 selected KGDEs around Sea, including caves, springs, rivers wetlands, were evaluated, based on local expert knowledge scientific literature. Results demonstrate that contribute considerably to...

Abstract. Flow in complex karst aquifers is challenging to conceptualize and model, especially poorly investigated areas, semiarid climates, under changing climatic conditions; however, it necessary order implement long-term sustainable water management practices. Thus, the objectives of this work were propose a calibration approach based on time series analyses for aquifer assess impact climate change spring discharge. Based more than 3 years high-resolution continuous monitoring,...

This article examines the relative impacts of anthropogenic interventions and global climate change on dynamics saltwater intrusion in highly urbanized coastal aquifers. For this purpose, simulations sea-level rise abstraction scenarios for near future were undertaken a pilot aquifer using multi-objective 3D variable-density flow solute transport model. We find that associated with has less influence encroachment salinity than abstraction, which more appreciable impact through greater...

Abstract Flow‐direction‐dependent (FDD) dispersivity in coastal aquifers (CAs) may strongly affect the inland extend of seawater intrusion (SWI) and accompanying vertical salinity distribution. FDD predict greater saltwater wedge, but less spreading than does classical flow‐direction‐independent (FDI) dispersivity, standard currently employed most numerical CA models. Dispersion processes play a key role SWI process directly pumped water quality. Constant FDI dispersivities be inappropriate...
