Abstract
The concentration of a tracer released into coastal waters is calculated from idealised equations in a simple domain. The length of the outfall pipe is found that renders minimum a cost function, which takes into account the impact of pollution and the cost of the release facilities. The optimal length is found to be independent of the cross-shore diffusivity coefficient, which is somewhat counterintuitive.
