New screening tool for obtaining concentration statistics of pollution generated by rivers in estuaries

Rivers present one of the crucial pathways for the waterborne transport and therefore estuaries are critical coastal areas for a pollution hazard that might lead to eutrophication and general water quality deterioration. When addressing these problems, the decision makers and coastal area managers often need additional skills and expert knowledge, so they engage consultants to develop models and provide potential solutions. The actual implementation of a solution in practice is hampered with different stakeholders’ interest and objectives. However, if the relevant institutions were provided with a screening tool, enabling them with a certain level of solution ownership, potentially more involvement would occur. This research utilizes analytical model based on ensemble averaging and near field approximations of the fundamental advective- diffusion equation for the case of continuous, steady, conservative substance transport where stream flow mean velocity is dominant. Such approach significantly reduces the costs and time needed to obtain enough measured data needed for common statistics analysis or more complex numerical model. Developed methodology is built into a simple software named CPoRT (Coastal Pollution Risk Tool) within recently conducted research project funded by European Social Fund. CPoRT is a free application which may be used by any stakeholder interested in an estuary pollution problem.
