      abstract = {Coastal aquifers are highly sensitive natural systems that  require careful management and adequate planning in order  to ensure that they are not over-exploited.  The  development of effective management strategies is  particularly pertinent to coastal communities faced with  increasing population pressures.  This paper develops a  multidisciplinary approach for the optimal extraction of  water from a coastal aquifer. The objective is to maximise  the net present value of the net economic benefits of  pumping, subject to various hydrological constraints.  A  nonlinear demand function is used to quantify the benefits  of water use, and analytical equations of groundwater flow  and saltwater intrusion are used to integrate core  principles of hydrology within the economic framework.  For  the optimisation of drawdown levels, a modified version of  the Theis (1935) solution is used to calculate drawdown  levels.  For the prevention of saltwater intrusion,  constraints are calculated using the single-potential  sharp-interface solution developed by Strack (1976).  The  model is then applied to a hypothetical coastal community  situated on the East coast of Australia.  The results  confirm the importance of accounting for spatial  heterogeneity and temporal effects when modelling  extraction from a complex natural system.  In addition, a  volumetric price of water is recommended as an efficient  policy tool for the control and regulation of demand.},
