Abstract Preservation of water quality in coastal areas has become an urgent challenge especially upon considering the increasing anthropogenic impacts, the expansion of urban areas and the predicted climate change in the upcoming decades. Dissolved oxygen (DO) may be considered the most important parameter to study the quality of water, in which the preservation of a reasonable rate of DO is essential for a healthy aquatic life. Herein, the water quality considering dissolved oxygen in coastal lagoons located in El Gouna, Egypt, is investigated using the TELEMAC-2D WAQTEL module. The simulation focused on the effects of the increasing water temperature on the quantity of DO, as lower levels of DO are expected in case of high temperatures. Studying the DO values and the sensitivity analysis of the affecting parameters helps to prevent and control anoxic problems in shallow areas, which occur if the DO concentration is less than 0.5 mg/l.
