Identification of intermittent point source capacity and location of the initial contamination plume

Abstract

While working on a model of mass impurity transition for the waters of the Sea of Azov and the Kerch Strait, we calculated the capacity of the immediate point source and identified the location of the initial contamination plume. Contamination source capacity identification is based on minimizing the quadratic functional of the forecasting quality and solving associated problems. Associated problem solving is also used in order to identify the location of the initial contamination plume in the body of water under analysis. The first goal was reached for the Gulf of Taganrog area, and the second one – for the Kerch Strait area. It must be noted that both areas have heavy marine traffic and experience the construction of new transport corridors. Simulation results were produced taking into consideration north-western winds that are dominant in the region. Quantitative experiments show that it is possible to identify the capacity of an intermittent point source of contamination using a three-dimensional model of mass impurity migration, as well as to identify the location of the initial contamination plume.
