Coastal tract, and island of Masirah

The desolate coastal tract from Jalan to Ras Naws has no specific name. Low hills and wastelands meet the sea for long distances. Midway along this coast and about fifteen kilometers offshore is the barren Masirah island. Stretching about seventy kilometers, the island occupies a strategic location near the entry point to the Gulf of Oman from the Arabian Sea. Because of its location, it became the site of military facilities used first by the British and then by the United States, following an access agreement signed in 1980 by the United States and Oman.

Oman interior

West of the coastal areas lies the tableland of central Oman. The Al Hajar Mountains form two ranges: the Al Hajar al Gharbi Mountains and the Al Hajar ash Sharqi (Eastern Al Hajar) Mountains. They are divided by the Wadi Samail (the largest wadi in the mountain zone), a valley that forms the traditional route between Muscat and the interior. The general elevation is about 1,200 meters, but the peaks of the high ridge known as Jebel Akhdar

Behind the Al Hajar al Gharbi Mountains are two inland regions, Az Zahirah and Inner Oman, separated by the lateral range of the Rub al Khali. Adjoining the Al Hajar ash Sharqi Mountains are the sandy regions of Ash Sharqiyah and Jalan, which also border the desert.

Environmental concerns

Natural hazards: Summer winds often raise large sandstorms and dust storms in the interior during periodic droughts. Following rain, Wadis can fill with rainwater water and vast tracts of land can be flooded. A cyclone making landfall can severely flood large areas, or blow sand all over the place.

Environment - current issues: Soil salinity is rising. There is beach pollution from oil spills. There are very limited natural fresh water resources
