Tactical uses of groundwater models

UsePurpose
Review water resources management plansEvaluation of the limits of sustainable water resources development
Local impact assessmentUse of the model to assess impacts of different groundwater management options on users, springs, river flows and wetlands
Forecast water supply yield for prevailing groundwater conditionsEstablish current resource state and determine the optimum groundwater use for the immediate future. This would include the forecasting of potential aquifer yield during a drought
Forecast need for mitigation measuresLinked to the previous use. Relates to the use of models in assessing mitigation needs such as river support and cutback/cessation of abstraction
Forecast operational yield of aquifer storage and recovery schemesTo assess the net gain in the short and long term
Climate changeAssessing the impact of climate change on groundwater resource systems
Land use changeImpact on groundwater resource system
Design of optimum hydrological monitoring networkEvaluation of the ‘value’ of monitoring facilities
Groundwater contaminationUse of groundwater flow model and associated datasets in contaminant transport studies (e.g. minewater and contaminated land remediation)
Groundwater quality forecastsUse of the model datasets in forecasting nitrate and other chemical pollutant concentrations in groundwater
Planning applicationsUse of the model and datasets to support hydrogeological impact assessments for new developments (e.g. mining)
