A sabkha (salt-flat) ecosystem known as the Dukhan Sabkha is found in the northern section of the Dukhan region in western Qatar. This sabkha, considered the largest inland sabkha in the Persian Gulf, runs for approximately 20 km, occupies an area of 73 km², has a width of 2 to 4 km and a depth of between 6 and 7 meters. It also accommodates the lowest point of Qatar, at six meters below sea level. Studies suggest that the sabkha is fed by seawater from the Bay of Zekreet, north by approximately 3 km.
