Groundwater Modelling of the Tindal Limestone Aquifer

This report looks at the interaction between the aquifer and Katherine River, and possible changes to river flow as a result of various groundwater use scenarios. The key issues relate to: understanding groundwater recharge rates and pre-development discharge rates to the Katherine River; assumptions concerning the conceptual hydrological model and refinements needed for previously developed groundwater models; the development scenarios and seasonal groundwater use patterns; and the timing and nature of surface water / groundwater interactions.
