Torriorthent and landscape AE
Soil profile: A representative soil profile of a Torriorthent in the Ras Al Khaimah Emirate, United Arab Emirates.
Landscape: These very deep, sandy-skeletal soils are along a dry, second bottom in Wadi Bih. They formed in sandy alluvial deposits with a large content of gravel, cobbles, and stones.
Torriorthents are fixed on the driest Torriorthents. Typic Torriorthents are extensive soils in the intermountain States of the United States. Most of them have moderate or strong slopes and are used only for grazing. Others that have gentle slopes are irrigated. The gently sloping soils are mostly on fans or piedmont slopes where the sediments are recent and have little organic carbon.
The particle-size control section has 35% or more rock fragments, including 15% or more cobbles and stones. The pH (1:1) ranges from 7.0 to 8.6 throughout the profile. The EC (1:1) is generally less than 1.0 dS/m in all horizons. Rock fragments ranging from gravel to stones and boulders cover the surface. A dark desert varnish is common on the exposed surfaces of the rock fragments.
The A horizon is 5 to 20 cm thick. It is 7.5YR or 10YR, value 3 to 6, and chroma 2 to 6. It is loamy sand, sand, or coarse sand, including very gravelly, extremely gravelly, very cobbly or extremely cobbly texture modifiers.
The C horizon has hue of 7.5YR, or 10YR, value of 4 to 7, and chroma of 2 to 6. It is loamy sand, sand, or coarse sand, including very gravelly, extremely gravelly, very cobbly or extremely cobbly texture modifiers. Pockets or lenses of sandy loam up to 5 cm thick are in some pedons. The vertical and under-sides of rock fragments, in some places, are coated with calcium carbonate. The C horizon may be extremely weakly to moderately cemented with carbonates. However, roots appear to be able to penetrate with a spacing of less than 10 cm. Some pedons do not have cementation.
Wādī Al-Biḥ, is a river/wadi that crosses the North-Western Hajar Mountains from the United Arab Emirates, and traversing Oman before returning to the UAE. From the West to the East, it originates in Ras Al Khaimah on the Gulf, before crossing the Omani exclave at the tip of the Musandam Peninsula, past the village of Zighi and into Fujairah at Dibba Al-Hisn, on the Gulf of Oman. The wadi is a popular location for birdwatchers.
