Abstract This study investigates the hydrogeochemical characteristics, water quality, and potential human health risks of groundwater in the Tavas Plain (Denizli, SW Türkiye). The groundwater of the alluvial aquifer, the main freshwater resource in the region, exhibits significant contamination by arsenic (As) and nit…

Bu çalışmada, Aksu Çayı Üst Havzası’ndaki yüzey sularının kalite özellikleri hidrojeokimyasal süreçler ve trofik durum göstergeleri birlikte değerlendirilmiştir. Bu kapsamda fiziksel parametreler, majör iyon bileşimi, besin tuzları ve klorofil-a konsantrasyonları analiz edilmiş; su kalitesi Yerüstü Su Kalitesi Yönetme…

Afetler, toplumların yaşam koşullarını ciddi şekilde etkileyen ve temel hizmetleri aksatan olaylardır. Deprem, sel ve kasırga gibi doğal afetler su altyapısına zarar vererek güvenli içme suyuna erişimi zorlaştırabilir. Bu durum su kaynaklı hastalıkların yayılmasına zemin hazırlayabilir. Bu nedenle su hijyeni ve güvenl…

Urban expansion threatens groundwater sustainability, yet regional-scale assessments can mask localized impacts. This study presents a GIS-based multi-criteria framework to quantify this ‘paradox of scale’, assessing the conflict between urban growth and the potential of groundwater recharge at Kahramanmaras¸, Türkiye…

Groundwater recharge is critical because it restores the underground aquifers that supply billions of people. Over-abstraction of groundwater without recharge can lead to falling water tables, land subsidence and long-term ecological damage. As natural recharge is slow in many areas, particularly in arid and semi-arid…

Groundwater is a major source of water supply in Diyala Governorate, Iraq. This study proposes an integrated framework for groundwater quality assessment and forecasting by combining the Entropy Weighted Water Quality Index (EWQI) with machine learning algorithms. A total of 855 groundwater samples were collected, of…

This study evaluates groundwater quality in the Bismil Plain (Diyarbakır, Southeast Türkiye) using a total of 208 samples collected from 26 wells during eight seasonal sampling periods conducted between 2022 and 2024. In each sample, pH, electrical conductivity (EC), and the major ions Ca2+, Mg2+, Na+, K+, Cl−, SO42−,…
