Umm Al-Samīm Salt Flat

The Umm Al-S\u0101m Salt Flat is a geographical feature located in the Arabian Peninsula. It is a type of playa, which is a flat-bottomed depression found in desert basins and along coasts in arid regions. These areas are periodically covered by water that evaporates, leaving behind deposits of salt, sand, and mud. Playas are known for their extreme flatness, with slopes typically less than 0.2 meters per kilometer. Saline playas, like Umm Al-S\u0101m, can be referred to by various local names, including salt flat, salada, or sabkha. The Arabian Peninsula itself is characterized by diverse physiography, including mountainous highlands, plateaus, and extensive sand deserts like the Rub\u02bf al-Khali and Al-Naf\u016bd.12
