Morphoscopic changes in Iraqi territorial waters and their border repercussions

Abstract
 The present study includes the analysis of morphological change in Iraqi coastline Khor Abdullah and entrance to Shatt Al-Arab (Al-Ruka Channel), as northwestern region Arabian Gulf is exposed different erosion depositions due suspended sedimentary load, comparison between periods studied showed severe some coastal areas other parts, which led changes shape extension barriers or tongues made them prominent, especially shallow sites (shoals) at Shaitanah, those changed parts appear maps British Admiralty, draw detailed curves surrounding varying depths. load head amounted 11,014 km2 year 2003, expanded 2011 12,680 km2, by adding sediments about 1,676 6,452,600 tons over 8 years, a rate 806.575 annually, 8.5% volume 1996 decrease river flows from Tigris, Euphrates, Karun. line lowest tide (zero line) cross-section waterway lines that it shares with Iran Kuwait, affecting location approved border Iraq largest was width this influenced erosion, sedimentation patterns, deflection tidal currents, well temporary effect port activities Abdullah.
