Mathematical model aided investigation of hydrodynamic properties of Ulubat lake

Abstract

Ulubat is a fresh water lake formed in a tectonic subsidence site located at the east-west direction to the south of Marmara Sea. The length of the lake at the east-west direction is 23-24 km and its width is about 12 km. The nearly triangular shaped surface area of the lake varies in a wide range according to seasons and years depending on precipitation. To protect the rich flora and fauna of the Ulubat Lake, which is one of the most important wetlands in Turkey, the hydrological and hydrodynamic properties should be well known. In this study, the hydrological balance of Ulubat Lake, flow patterns formed under various wind directions and velocities and its effects on the water quality is investigated by using a developed mathematical model.
