Water balance models provide significant input to integrated models that are used to simulate river basin processes. However, one of the primary problems involves the coupling and simultaneous calibration of rainfall-runoff and groundwater models. This problem manifests itself through circular arguments – the hydrologic model is modified to calculate highly discretized groundwater recharge rate...

Dieback of native Eucalyptus largiflorens forests is an increasing problem on the floodplains of the lower River Murray, southern Australia. Salinisation of floodplain soils, as a result of the changed hydrological management of the River Murray, appears to be a primary cause of the dieback. Regulation of the River Murray has reduced the frequency of large flood events by a factor of approximat...

This paper primarily deals with sustainability issues linked to groundwater use. First, it shows that the debate on the traditional indicator to assess overdraft situations – average abstractions higher than average recharge – fails to introduce many dimensions of sustainability. A dynamic description of the effects of pumping and the introduction of the concept of capture, defined as the sum o...

Groundwater provides a reliable tap to sustain agricultural production, yet persistent aquifer depletion threatens future sustainability. The High Plains Aquifer supplies 30% of the nation's irrigated groundwater, and the Kansas portion supports the congressional district with the highest market value for agriculture in the nation. We project groundwater declines to assess when the study area m...

Groundwater depletion is the natural consequence of withdrawing water from an aquifer at a higher rate than recharge. If groundwater abstraction exceeds recharge for extensive areas and long time, overexploitation or persistent can occur [...].

A detailed study of groundwater flow and solute transport was performed in the recharge area of the Union brewery groundwater resources in Ljubljana. The main study goal was the assessment and prediction of movement of groundwater and urban contaminants through the unsaturated or/and saturated zone of the Pleistocene sandy-gravel aquifer and the risk assessment of contamination of the groundwat...

Groundwater recharge estimates are required for the management of river basin districts under the new Water Framework Directive. Different recharge estimation techniques are described in this paper according to the following categories: inflow estimation, aquifer response analysis, outflow estimation and catchment water balance. Examples of their application in Ireland are provided. All estimat...

IMPLICATIONS OF THE LATE NOACHIAN “ICY HIGHLANDS” MODEL FOR MELTING AND GROUNDWATER RECHARGE ON THE THARSIS RISE. J. P. Cassanelli, J. W. Head, J. L. Fastook, Brown University Department of Earth, Environmental and Planetary Sciences, Providence, RI 02912 USA, University of Maine, Orono, ME 04469 USA. ([email protected]). Introduction: During the Late Noachian (LN), Hesperian, and ear...

Artificial recharge of groundwater is achieved by putting surface water in basins. furrows, ditches, or other facilities where it infiltrates into the soil and moves downward to recharge aquifers. Artificial recharge is increasingly used for shortor long-term underground storage. where it has several advantages over surface storage, and in water reuse. Artificial recharge requires permeable sur...

Wastewater can be regarded as a valuable resource that can be re­ used in various ways, creating more sustainable societies which can benefit both human communities and the environment. An issue when using reclaimed water is the potential presence of health hazards such as microbial pathogens. The presence of pathogens can often impact on the type of water reclamation project selected. Artifici...
