The influence of groundwater management strategies on groundwater levels of Namibian savannah aquifers
… potential evaporation rates beyond 2000 mm/year. Groundwater therefore quickly becomes crucial, most of which is located in aquifers in the savannah biome which covers a large part of the country. This is also where most industrialization as well as most farming is practiced. It is however unknown …

Machine Learning methods for providing groundwater management insights in semi-arid alluvial aquifers
Accurate regional groundwater level (GWL) forecasting is critical for evaluating the impacts of groundwater withdrawals on water resource sustainability, especially during droughts. A lack of hydrogeological data often makes it challenging to develop water balance models that forecast the impacts …

Groundwater management using a GIS case study : Uitenhage Subterranean Government Water Control Area
… forms the centre of one of the biggest artesian groundwater basins in South Africa. The Table Mountain Group quartzitic sandstones are overlain by a thickness of postPalaeozoic sediments giving rise to artesian groundwater. The most wellknown of this manifestation are the springs at Uitenhage …

Addressing climate-driven challenges in groundwater management and coastal hydrogeology through numerical modeling
Addressing groundwater management and coastal hydrogeology in a changing climate requires an integrated approach using numerical modeling and geophysics. This dissertation explores groundwater sustainability, seismic risks, and submarine permafrost dynamics. The first two chapters examine the SWIFT …

Assessment of groundwater management for domestic use from IWRM perspective in upper Limphasa river catchment, Malawi
… factors in Malawi in relation to current management and usage of water resources were explained.With 1,321m3 per capita per year against index thresholds of 1,700-1,000m3 per capita per year, this study showed that Malawi is a physically water stressed country but not physically water …

A New Approach to Texas Groundwater Management: An Environmental Justice Argument to Challenge the Rule of Capture
… on English Common Law, as a means of regulating groundwater resources. Many of the western states originally used the rule of capture to regulate their groundwater resources, but over time, each of these states replaced the rule of capture with other groundwater laws and regulations. The Texas …

Developing methodologies for sustainable groundwater management in sub-Saharan Africa: a case study of the Chad Basin around Maiduguri, Nigeria
This study developed sustainable groundwater management methodology applicable to sedimentary environments in sub-Saharan Africa, taking the Chad basin, Northeastern Nigeria as a case study. The study employed integrated methodological approaches and is divided into three major interrelated phases. …

INTEGRATED AQUIFER VULNERABILITY ASSESSMENT OF NITRATE CONTAMINATION IN CENTRAL INDIANA
Groundwater is not easily contaminated, but it is difficult to restore once contaminated. Therefore, groundwater management is important to prevent pollutants from reaching groundwater. A common step in developing groundwater management plans is assessment of aquifer risk using computational …

Hard and soft cap groundwater allocations: a comparison of groundwater pumping restrictions on hydrologic and economic outcomes
"While groundwater is an important primary and supplementary source of water in the western United States, its overuse can lead to negative consequences such as stream depletion, seawater intrusion, or land subsidence. An increasing number of groundwater management districts are restricting …

A neural network-based method for evaluating a spatially distributed parameter field: An application in groundwater remediation under uncertainty
… is an important issue in the design of reliable groundwater remediation strategies. Using groundwater management models based on a stochastic approach to groundwater flow, where the log-hydraulic conductivity is represented as a random field, is a frequently studied technique for the design of …

Three approaches to measuring natural resource scarcity : theory and application to groundwater
… cost of extraction and scarcity rents. Since groundwater resources exhibit natural supply constraints, scarcity rents must be imposed on current users. Given the difficulty of establishing clear groundwater ownership rights, scarcity value frequently goes unrecognized and is difficult to …

Integrating Groundwater Conservation and Risk Mitigation under Uncertainty: Strategies for Sustainable Aquifers and Agriculture
Groundwater is a crucial resource for agricultural production globally, especially in water-scarce regions. However, increased irrigation demands, weak governance, and climate change-induced variability threaten the sustainability of aquifers, jeopardizing long-term agricultural productivity. This …

Impacts to Anadromous Fish through Groundwater Extraction
<p>California uses more groundwater than any other state in the United States in order to meet agricultural demand during the growing season when water is naturally least available due to the state’s Mediterranean climate. The state also hosts populations of anadromous fish that are otherwise found …

Multi-agent real-time decision making in water resources systems
… operation and competition for a common pool groundwater source. Reservoir operation is modeled as a single agent stochastic optimal control problem where the operator (agent) negotiates a firm power contract before operations begin and adjusts the reservoir release during operations. A …

The design and testing of a procedure to locate fresh submarine groundwater discharge in Cyprus
… procedure for identifying fresh submarine groundwater discharge (SGD) in Cyprus. SGD is a flow of water from coastal aquifers into the ocean driven by a hydraulic gradient and other forces. Understanding SGD is crucial for informed groundwater management. In some cases, SGD creates …

Time series modelling of groundwater levels in a selected semi-arid catchment within Vhembe District Municipality, South Africa
This study is aimed at modelling groundwater levels in a semi-arid catchment within Vhembe District Municipality, South Africa. Auto Regressive Integrated Moving Average (ARIMA) model and Seasonal Auto Regressive Integrated Moving Average with eXogenous variables (SARIMAX) model were used to model …
