  • Groundwater resource exploration

    Resistivity method is very suitable for groundwater exploration. Two methods can be used, the surface method and crosshole method. Surface method is cost effective, though it is sometime not as accurate as the crosshole method. Geologists usually narrow down the exploration area and then operators can use geophysical methods to find groundwater.  Surface method involves laying two cables on ...

  • Making Australian groundwater data accessible: the value of collaboration

    Access to nationally consistent information is essential to support informed decision-making about Australia's vital groundwater resources. However, until now it has been difficult to depict a seamless national picture of groundwater resources and frame groundwater issues at a national scale. This is because groundwater data is typically managed locally without consistent format or ...

  • Research on the evaluation method of groundwater quantity and pollution vulnerability

    Current research on groundwater vulnerability is aimed mainly at groundwater pollution vulnerability (GPV), and the vulnerability of groundwater quantity is seldom considered. It is important to carry out the groundwater vulnerability evaluation for the management of groundwater resources. This paper presents evaluation models and methods for assessing groundwater quantity and pollution ...

  • Groundwater management for adaptation under changing climate conditions in Indian Punjab

    India is the largest groundwater user in the world, with an estimated usage of around 230 km3 per year. Agricultural demand for irrigation is already the single largest draw on India's water, yet estimates by the Ministry of Water Resources indicate that by the year 2050 irrigation needs will rise by 56%. From the climate change viewpoint, India's groundwater hotspots are ...

  • Multi-electrode resistivity survey for groundwater exploration in the Harare greenstone belt, Zimbabwe

    A multi-electrode resistivity survey, carried out over metasedimentary strata and metavolcanics in the Harare greenstone belt in northeastern Zimbabwe as part of a groundwater resources investigation, illustrates the ability of this technique to produce high-resolution images of the subsurface, which are useful for groundwater resources assessment. The resistivity results provide a clear view of ...

  • Swarm intelligence for groundwater management optimization

    This paper presents some simulation–optimization models for groundwater resources management. These models couple two of the most successful global optimization techniques inspired by swarm intelligence, namely particle swarm optimization (PSO) and ant colony optimization (ACO), with one of the most commonly used groundwater flow simulation code, MODFLOW. The coupled simulation–optimization ...

  • A new hydrological balance and water management issues in Zakynthos Island, Greece

    The use of groundwater resources in Zakynthos Island in the Ionian Sea at central Mediterranean has become extremely intensive during the last decades, due to the high rate of urbanisation, tourist development and irrigated land expansion and is estimated being 15 hm 3 /year. Different methods are being required when water-related sustainability issues are examined like development analysis, ...

  • Towards an effective protection of groundwater resources: putting policy into practice with the drinking water protection file

    Groundwater in the Netherlands is a major resource for drinking water. As such it must be carefully monitored and managed. Evaluation of the European Water Framework Directive (EU-WFD) showed that protection of this valuable resource needs improvement. The Drinking Water Protection File identifies necessary measures needed per water abstraction site. The Protection File is part of the Dutch ...

  • Groundwater level forecasting using SVM–PSO

    The prediction of groundwater levels in a basin is of immense importance for the management of groundwater resources. In this study, support vector machines (SVMs) is used to construct a ground water level forecasting system. Further the proposed SVM–PSO model is employed in estimating the groundwater level of Rentachintala region of Andhra Pradesh in India. The SVM–PSO model with various input ...

  • A transboundary aquifer of potential concern in Southern Africa

    Tuli Karoo transboundary aquifer (TBA) is shared between Botswana, South Africa and Zimbabwe in the Southern African Development Community (SADC) region. The TBA provides groundwater resources for various economic activities. Irrespective of the value offered by this TBA, there is very little research that has been conducted to improve understanding of the physical system and potential ...

  • Aquifer recharge for securing water resources: the experience in Llobregat river

    The Llobregat Delta Aquifer has historically been a strategic water supply resource to the Barcelona metropolitan area. The use of river water combined with the exploitation of groundwater resources during dry periods has enabled the demographic and economic growth of the Barcelona area during the last fifty years. The aquifer overexploitation has entailed the decrease of groundwater level and ...

  • Water management problems in the Copiapó Basin, Chile: markets, severe scarcity and the regulator

    This research focuses on the determination of the factors that led to the failure of water management in the Copiapó Basin in Chile. Interestingly, the existence of full private ownership and free tradability of water rights has not prevented the overexploitation of groundwater resources. In the paper, firstly, water regulation and the role of the regulator in Chile are briefly discussed. ...

  • A GIS-based Modified DRASTIC (ANP) method for assessment of groundwater vulnerability: a case study of Nagpur city, India

    Quality of groundwater is as important as quantity. For effective planning and management of groundwater resources, groundwater vulnerability assessment is most significant. The objective of the present study was to evaluate the groundwater vulnerable zones of Nagpur city, using Modified DRASTIC methods within a Geographical Information System (GIS) environment. DRASTIC method has been ...

  • A two steps solution approach to solving large nonlinear models: application to a problem of conjunctive use

    This article describes a solution method of solving large nonlinear problems in two steps. The two steps solution approach takes advantage of handling smaller and simpler models and having better starting points to improve solution efficiency. The set of nonlinear constraints (named as complicating constraints) which makes the solution of the model rather complex and time consuming is eliminated ...

  • Water resources and management in Tunisia

    This paper focuses on the work done through the INRGREF to collect and analyse available information on water resources in Tunisia. It presents the quantity and quality of surface and groundwater resources data. Water resources in Tunisia are characterised by scarcity and a pronounced irregularity. Tunisia has been able to develop a complex and diverse water infrastructure allowing the country to ...

  • Groundwater governance: explaining regulatory non-compliance

    This paper explores the non-compliance of water users through a case study of groundwater resources in the Gulf Islands (British Columbia (BC)) and the San Juan Islands (Washington). The research challenges two assumptions: that local regulations can easily incorporate scientific research, which in turn leads to sound on-the-ground management; that sound on-the-ground management translates into ...

  • Performance of intermittent aeration reactor on NH4-N removal from groundwater resources

    To study the effect of intermittent aeration period on ammonium–nitrogen (NH4-N) removal from groundwater resources, synthetic groundwater was prepared and three reactors were operated under different conditions – “reactor A” under continuous aeration, “reactor B” under 6 h intermittent aeration, and “reactor C” under 2 h intermittent aeration. To facilitate denitrification simultaneously with ...
