Lake Alimini Grande is a salt-marsh ecosystem on the Adriatic coast of southern Italy (40.19°-40.22°N, 18.44°-18.46°E). Lake Alimini Grande has a surface area of 1.37km2, a sinuosity index of 2.29, an average depth of 1.5m and a volume of 2.1x106m3. It has an irregular shape (major axes:2.86km, minor axes:1.54km) and it is affected by dominant winds of the area along its major axes. It is connected with the sea through its mouth (length: 100m, width: 15m) and with a freshwater lake, Alimini Piccolo, through a natural canal 1.5km long, called the “Strittu”. The lake receives freshwater inputs from the Lake Alimini Piccolo in the South, from the Zuddeo Canal in the North-West and from the Traugnano Swamp in the North. The freshwater fluxes vary seasonally since in the Apulian region the climate is very hot and dry during summer
