  • Groundwater data network interoperability

    Water data networks are increasingly being integrated to answer complex scientific questions that often span large geographical areas and cross political borders. Data heterogeneity is a major obstacle that impedes interoperability within and between such networks. It is resolved here for groundwater data at five levels of interoperability, within a Spatial Data Infrastructure architecture. ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • GroundWater Markup Language (GWML) – enabling groundwater data interoperability in spatial data infrastructures

    Increasing stress on global groundwater resources is leading to new approaches to the management and delivery of groundwater data. These approaches include the deployment of a Spatial Data Infrastructure (SDI) to enable online data interoperability amongst numerous and heterogeneous data sources. Often an important component of an SDI is a global domain schema, which serves as a central structure ...

  • Making the invisible visible: the impact of federating groundwater data in Victoria, Australia

    The Visualising Victoria's Groundwater (VVG) web portal federates groundwater data for the State of Victoria, Australia, thus making legacy data, government datasets, research data and community-sourced data and observations visible to the public. The portal is innovative because it was developed outside of the government and offers real-time access to remote authoritative databases by ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • The application of groundwater modelling to simulate the behaviour of groundwater resources in the Ramhormooz Aquifer, Iran

    In this study, groundwater modelling was proposed as management tool in Ramhormooz Plain, south western Iran. After definition of a conceptual model, the necessary data were defined into various packages of MODFLOW. Subsequently, the model was calibrated by trial and error estimation and the results were finally optimised by PMWIN through PEST code. After verification process, the model was used ...

  • Potential impact of heterogeneity on groundwater age

    Groundwater age is an important water property used as an indicator of groundwater quality. There have been no sufficient data and measurements underground, and that problem has been mitigated by using direct simulation of groundwater age. This paper has been motivated by the work of Daniel J. Goode, defining a rather different approach. A numerical model has been developed, using the Lagrangian ...

  • Kenya - Groundwater governance case study

    This report presents a case study on groundwater governance in Kenya. The objectives of the study were to: (a) describe groundwater resource and socioeconomic settings for four selected aquifers; (b) describe governance arrangements for groundwater management in Kenya; and (c) identify the relevance of these arrangements for planning and implementing climate change mitigation measures. The report ...

  • Assessment of riverside groundwater flood risk induced by high river water levels using a numerical model and monitoring data

    Large barrages have been constructed on the main rivers in South Korea to store water and mitigate fluvial flooding damage. However, the increase in water levels behind the barrages can potentially lead to a rise in groundwater levels in the riversides. The purpose of this study was to describe the effect of a barrage on groundwater levels and to test the applicability of a numerical model to ...

  • A grid-based integrated surface–groundwater model (GISMOD)

    A distributed hydrological model, the Grid-based Integrated Surface-groundwater MODel (GISMOD), was developed to simulate hydrological processes by considering water interaction among different soil layers. The model integrates six modules. Basic information on catchment, such as the flow direction and the drainage network, can be obtained automatically from digital elevation model (DEM) data ...

  • Water dynamics and groundwater recharge in a deep vadose zone

    Understanding soil water dynamics and accurately estimating groundwater recharge are essential steps in achieving efficient and sustainable management of groundwater resources in regions with deep vadose zones. The objective of this study was to understand transient data and the dynamics nature of water from deep sections at the thick vadose zone, and to estimate groundwater recharge by ...

  • In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

    A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

  • Characterisation of arsenic contamination in groundwater by statistical methods

    Statistical investigation on groundwater arsenic concentration data of southwest Bangladesh was performed. Two data sets of 1998–99 and 2002–03 were selected for this analysis. Summary statistics of the data shows that the mean concentration exceeds the Bangladesh limit (0.05 mg/l) in all areas. Normality of arsenic concentration data was checked by frequency histogram, skewness coefficient and ...

  • Spatial assessment of groundwater demand in Northwest Bangladesh

    Spatial assessment of groundwater demand has been carried out as a part of sustainable water resources management in Northwest Bangladesh. ASTER images are synthesised for extracting the extent of irrigated land. The Penman?Monteith method is used for the calculation of reference evapotranspiration from climate data. Soil information is used for the estimation of water requirement for land ...

  • An OpenMI module for the groundwater flow simulation programme Feflow

    The OpenMI standard defines an interface that allows time-dependent models to exchange data at runtime. The migration of a flow simulation programme to OpenMI compliance usually requires changes in the source code or even a reorganisation of the programme sequence. Users of commercial flow simulation programmes depend on the software producer if they want to couple their models according to the ...

  • Evaluating groundwater sustainability for fractured crystalline bedrock

    Water sustainability is an important concern for communities that rely on groundwater in fractured rock; yet the complexity of the fracture system and the unknown rate of recharge make quantifying groundwater availability difficult, if not impossible, using conventional water balance calculations. This study provides a new approach for estimating groundwater sustainability in fractured rock that ...

  • Mathematical model predicting arsenic bioleaching in groundwater treatment

    In the Southeast Asia region, arsenic contamination of groundwater has been reported in several countries and a large number of arsenic treatment units were installed in many regions. Microbial activity can greatly affect the mobilization of arsenic under anaerobic conditions when coupled with the oxidation of organic matter. In this study, a mathematical model was developed to predict the ...
