Abstract
This study presents a methodology for the management of surface water quality which guarantees that the concentrations of pollutants remain within acceptable levels. The paper presents different optimisation tasks that can be used for managing the quality of surface waters. The paper presents calculations for a hydrographic network with both point and non-point pollution sources. The calculations include the total BOD and the dissolved oxygen concentrations. The author shows how different types of optimisation tasks affect the chemical profiles of the receiving water.
