| ABSTRACT: | The depth of seawater intrusion in a coastal aquifer is often measured by the distance from the coastline to the toe of a fictitious, yet well-defined, sharp seawater-freshwater interface. The paper considers the problem of estimating the location of the toe on the basis of prior information and of posterior information that can be obtained by adopting an interface model and installing an observation well. The solution to the problem involves decisions regarding the worthwhileness of drilling the well and its optimal location. A methodology is proposed for solving the problem by employing the Bayesian approach to decision making under uncertainty with the sum of expected risk and cost as the objective function. An alternative to installing a well may be the acquisition of additional prior information in order to reduce the prior range of uncertainty regarding the position of the toe. The problem then is solved by comparing the expected net benefit from acquisition of prior information only against the net benefit from acquisition of prior information, adoption of an interface model, and installment of a well. |
