To improve the water quality of Lake Manzala in Egypt, a project was undertaken to enhance the ElBoghdady outlet, allowing better water exchange with the sea. This involved dredging channels to connect the outlet with the sea and the lake. Researchers developed a model to simulate water quality in the lake and found that after the modifications, the levels of pollutants like phosphates and ammonia decreased by around 20%, while dissolved oxygen increased by 1.74%. The project successfully improved the water quality and reduced eutrophication in the lake by enhancing the connection with the sea through the ElBoghdady outlet.
