  • The Ganges water treaty: 20 years of cooperation, on India's terms

    International cooperation has become a universal mandate for governing transboundary waterbodies. Diverse stakeholders promote cooperation as a desirable, if not indispensable, approach from which to achieve sustainable and equitable benefits and for the creation of transboundary waterbodies. However, calls for international water cooperation operate from the presupposition that cooperation is ...

  • 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 ...

  • 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. ...

  • 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 ...

  • Forecasting performance of support vector machine for the Poyang Lake's water level

    The growth of forecasting models has resulted in the development of an excellent model known as the support vector machine (SVM). SVMs can find a global optimal solution equipped with kernel functions. This research trains and tests the SVM network and constructs the support vector regression prediction model by using hydrologic data. Six hydrologic time series were calculated by different ...

  • An ontology-based knowledge management framework for a distributed water information system

    With the increasing complexity of hydrologic problems, data collection and data analysis are often carried out in distributed heterogeneous systems. Therefore it is critical for users to determine the origin of data and its trustworthiness. Provenance describes the information life cycle of data products. It has been recognised as one of the most promising methods to improve data transparency. ...

  • A normalized regression based regional model for generating flows at ungauged basins

    Revision of existing methodologies for generating monthly-flow series at ungauged basins based on multivariate nonlinear correlation has led to a simple two-parameter model. While the existing methodology used hydrological, meteorological and geomorphologic input data, the proposed model requires hydrological and geomorphologic input data only. The proposed methodology requires formation of ...

  • 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 ...

  • Wavelet and neuro-fuzzy conjunction model for predicting water table depth fluctuations

    The ability of a wavelet and neuro-fuzzy conjunction technique for groundwater depth forecasting was investigated in this study. The wavelet-neuro-fuzzy model was improved by combining two methods, the discrete wavelet transform and the neuro-fuzzy model. The conjunction model was applied to different input combinations of daily groundwater depth data of Bondville and Perry wells. Root mean ...

  • Copula-based stochastic simulation of hydrological data applied to Nile River flows

    Modelling a multivariate distribution is a classical issue in statistics. Copula functions offer a useful solution to this issue by modelling the multivariate distribution as a function of its marginal distributions. They have been used in various problems in hydrology and water management such as flood frequency analysis and drought or rainfall intensity-duration frequency analysis. However, to ...

  • Dynamical downscaling of precipitation in Iceland 1961–2006

    Atmospheric flow over Iceland has been simulated for the period January 1961 to July 2006, using the mesoscale MM5 model driven by initial and boundary data from the European Centre for Medium Range Weather Forecasts (ECMWF). Firstly, the simulated precipitation is compared to estimates derived from mass balance measurements on the Icelandic ice caps. It is found that the simulated precipitation ...

  • Deployment of a Deep Borehole Observatory at the High La ke Project Site, Nunavut, Canada

    Abstract We deployed a deep permafrost observatory in a borehole at the High Lake Project Site (67°22'N, 1I0°50>W), Nunavut, Canada with the aims of (1) investigating the physical and chemical limitations on microbial life within such environments, (2) developing life-detecting technologies for the exploration of life on Mars and (3) constraining the hydrological and thermal ...

  • Analysis of Hydrologic Data to Evaluate Phytoremediation System Performance

    Abstract A long-term environmental monitoring program is providing hydrologic data that demonstrates poplar trees are influencing groundwater flow at the J-Field site, Aberdeen Proving Ground, Maryland. Advanced data collection and analyses techniques have enabled researchers to construct a water budget for the study area and to estimate the amount of groundwater the trees are transpiring on a ...
