Hydrogeological Modelling of the Esperance Drinking Water Aquifer Subjected to Seawater Intrusion

Saltwater intrusion in groundwater is a concern in many aquifers around the world. It results in deterioration of potable and irrigation water quality and degradation of ecosystems. The problem is exacerbated by fresh groundwater abstraction, drying climates and a rising seawater level.<br/>Esperance is a small town situated on the south coast...

Sustainability of groundwater resources in Kumasi, Ghana: Estimating potential groundwater recharge using a water-balance approach and remote-sensing data in Google Earth Engine

Groundwater use has seen a significant increase in the rapidly urbanising city of Kumasi, Ghana, due to its reliability, general good quality, and low-cost development. Conversion of vegetated to urban land along with the challenges of growing groundwater abstraction has put the groundwater system at risk. This study aims to assess how the...

Monitoring Groundwater flow with ERT

Geophysical monitoring is a popular tool in aquifer characterization and groundwater flow. To address this objective at groundwater extraction site ‘t Klooster, an ERT dataset was analyzed to identify groundwater flow patterns resulting from the injection of warm oxygenated water. Using a petrophysical model, changes in resistivity were...

The role of behavioural willingness on mitigating saltwater intrusion in the Vietnamese Mekong Delta: Combining socioeconomic data with groundwater simulations using Bayesian Belief Networks

Fresh water resources in coastal areas are under intense pressure from groundwater consuming activities, sea level rise and extreme weather events, which effectively amplify salt water intrusion (SWI) into coastal freshwater aquifers. Literature on SWI describe the effects of SWI, model SWI scenarios and explain possible SWI mitigation...

Forensic hydrology reveals why groundwater tables in the province of Noord Brabant (the Netherlands) dropped more than expected

Since the nineteen fifties, groundwater levels in the Netherlands dropped more than as simulated by hydrological models. In the rural sandy part of the Netherlands, the difference amounts to approximately 0.3 m on average. The answer to the question of what or who caused this 'background decline' of groundwater tables may have juridical and...
