Ecotoxicology is the study of the effects and fate of contaminant substances on ecosystems. It aims to determine if there is an ecological risk by comparing the concentration that produces toxic effects with the environm...

The purpose of this study was to assess hydrological controls (e.g., rainfall, irrigation practices, river discharge, dam operation, evaporation) on surface (SW)- ground water (GW) interactions in an irrigated valley wit...

Abstract Globally groundwater depletion threatens water security with aquifer storage declining at 300 km³/year. Climate change intensifies flood frequency and magnitude causing agricultural and other losses. Punjab, I...

The impact of land use changes on watershed morphometry has shifted the delivery of ecosystem services from river-centric to aquifer-centric in the Ganga River Basin. We assessed the hydrosociology of 4830 dugwell develo...

Abstract The Colorado River Basin (CRB) is experiencing persistent aridification due to a complex interplay of natural and anthropogenic activities, resulting in significant groundwater depletion across the region. We us...

Abstract Groundwater provides a vital component of water supplies in semi-arid environments, wherein its quality directly influences ecosystem stability and human well-being. This investigation presents the first complet...

ABSTRACT In a context of rapid deforestation and agricultural expansion, the GOD (Groundwater type, Overall lithology of aquifer, and Depth of groundwater) approach can be used to identify areas most susceptible to diffu...

Fluoride (F−) in groundwater affects its suitability for domestic use, particularly drinking, posing health concerns for consumers. This study investigates the hydrogeochemical characteristics and potential health risk...

Abstract This study aimed to map geological structures and characterize groundwater aquifers in the Meki–Alemtena area of the East Shewa Zone, Ethiopia. Sixteen Vertical Electrical sounding data were collected to revea...

Assessing the characteristics of groundwater variations in areas affected by artificial recharge is essential for guiding the groundwater resources management and groundwater ecology. However, it is still a challenging t...

Purpose. This study evaluates groundwater contamination and associated human health risks arising from brewery effluent discharge in Aba, southeastern Nigeria, with emphasis on hydrogeochemical processes and probabilisti...

Abstract Groundwater is a key water source for many Ghanaian communities, yet it remains highly vulnerable to pollution from human-induced activities, particularly in urban areas such as Kokompe, where domestic and indus...

In arid ecosystems, evapotranspiration generally exceeds precipitation, preventing deep drainage and groundwater recharge. We propose that vegetation changes associated with the establishment of pastoralist settlements (...

Runoff, groundwater recharge and discharge, and surface water-groundwater interaction are the main driving forces of wetlands. The quantification of such flows is crucial information in the restoration and management of ...

The model test system designed is in accordance with the conditions of foundation pit engineering, which can simulate the groundwater seepage. It is composed of a soil box, a drainage box, a feed-water tank, an upper wat...

Climate change is undermining the effectiveness of static reserve systems by shifting species distributions and increasing the opportunity costs of conservation, particularly for land and water under more frequent temper...

ABSTRACT: Groundwater occupies the forefront in areas where there are no sources of surface water from rivers and irrigation projects, and this applies to the study of sector Sinjar, located in the north-west of Iraq and...

On the coast of the outer Río de la Plata estuary (Argentina) there is a vast coastal wetland occurring in a marsh environment. The hydrodynamics of this wetland is subject to a semidiurnal microtidal regime which cause...

Understanding nitrogen (N) exchange between cultivated ecosystems and groundwater becomes crucial in the Rolling Pampas where high and variable water table levels are accompanied by increasing N-fertilization rates. Fiel...

ABSTRACT To evaluate the efficiency of naturally derived chitosan as a bio-adsorbent to improve water quality in Jefara plain and health condition, male Wistar rats divided into 7 groups: group I (drinking unpolluted wat...

Ground water quality of Gonsia area which distance (about 35 km) western Mosul city were investigated, the study area suffer from water shortage, the only available water is bad quality from wells . Ten wells were cho...

In the present work 20hand-dugged and Artesian wells were chosse from Hamad Aga Al-Tathani and Hateen dwelling quarter for studying water quality .Samples of water were analyzed for determination of the following para...
