Beach groundwater dynamics: measurement and modelling. Beach groundwater is a highly complex, dynamic system interacting with tides, waves and swash. Such interactions affect beach sediment movement and contaminant transport/transformation in coastal aquifers. This project aims to measure and model the groundwater's behaviour at three different types of beaches: sand, gravel and gravel-sand mixed beaches. The study will provide much needed understanding and quantification of the beach groundwate ....Beach groundwater dynamics: measurement and modelling. Beach groundwater is a highly complex, dynamic system interacting with tides, waves and swash. Such interactions affect beach sediment movement and contaminant transport/transformation in coastal aquifers. This project aims to measure and model the groundwater's behaviour at three different types of beaches: sand, gravel and gravel-sand mixed beaches. The study will provide much needed understanding and quantification of the beach groundwater dynamics over a range of time scales. The outcome will help to assess the extent and intensity of mass and momentum exchanges across the beach face, and the resulting effects on beach stability and the fate of contaminants in coastal aquifers.Read moreRead less
Amelioration strategies to reduce environmental deterioration and agricultural production losses in water repellent regions. Millions of hectares of potentially productive agricultural land in Australia are affected by water-repellency. Water repellency causes non-uniform infiltration of water in soils and promotes surface erosion. Consequently, water repellent soils cannot be satisfactorily used for agricultural production, resulting in production losses of millions of dollars annually. This in ....Amelioration strategies to reduce environmental deterioration and agricultural production losses in water repellent regions. Millions of hectares of potentially productive agricultural land in Australia are affected by water-repellency. Water repellency causes non-uniform infiltration of water in soils and promotes surface erosion. Consequently, water repellent soils cannot be satisfactorily used for agricultural production, resulting in production losses of millions of dollars annually. This investigation is part of a genuine international effort that will develop new procedures to ameliorate water-repellent soils. New and improved mathematical models and decision support tools will also be developed to improve water-repellent land management, reduce environmental risk and minimise agriculture production loss.Read moreRead less
