Nitrate pollution of groundwater has increased dramatically worldwide due to increase of
population and agricultural productivity. The resulting nitrate concentration in groundwater is …

Groundwater is one of the most important water resources around the world, which is
increasingly exposed to contamination. As nitrate is a common pollutant of groundwater and …

The following paper presents a discussion of spatial and temporal distribution of
groundwater discharge estimates at a regional scale for two coastal aquifer systems in the …

Predicted changes in climate will lead to seawater intrusion in the Querença-Silves (QS)
coastal aquifer (south Portugal) during the coming century if the current waterresource …

Karstified carbonate aquifers may receive significant recharge contributions from losing
streams, hence, the knowledge about surface water‐groundwater (SW‐GW) interactions is …

The Algarve region of Portugal is experiencing severe water scarcity with existing water
supplies insufficient to meet demand, with limited resilience to drought. Managed aquifer …

Climate change poses a significant threat to water resources in southern Portugal. To
understand the potential impacts on surface and groundwater resources, this study …

Aquifer sustainable yields are often defined as a single value based on long-term averages
or annual values of recharge. However, these time scales can be too coarse for the systems …

Karst aquifers in semi-arid regions, like Queren double dagger a-Silves (Portugal), are
particularly vulnerable to climate variability. For the first time in this region, the temporal …
