Geomorphology of Shore Platform on the Northwest Coast of Qatar Peninsula

   Shore Platforms spread on the northwestcoast of Qatar Peninsula under study extends between Latitudes 25° 31′ - 25° 59′ North and Longitudes 50° 47′ - 51° 1′ East.

   The phenomena of marine shore platforms is considered one important Geomorphological phenomena that researchers have not given due attention to because of the need to profoundly understand other marine phenomena to manage and reduce its hazards.

   Marine Platform morphologies are characterized by the existence of two kinds of platforms: Type A: sloping platforms (Wave cut platform) and Type B: horizontal platforms. Generally, platforms are characterized by simple slopes and low heights.

   Platform expansion is increased by the decrease of the marine cliff. There are accurate measurements to measure the rates of the micro erosions in the foundation rocks in marine platforms, which are micro – erosion meter (MEM).

   Erosion rates differ throughout marine platforms sectors. Erosion increases in the margins of the platform to the direction of the land and sea more than it does in the middle of the platforms.  Some micro phenomena appear on the shore platforms like solution pools, ramps, and coastal potholes on the platforms.
