Secondly, a Protocol Relating to the Delimitation of the River Boundary between Iran and Iraq included an annex of four charts of the Shatt al Arab containing the coordinates of the points in the river. Finally, a Protocol Relating to the Security of the Boundary between Iran and Iraq contained an annex listing the infiltration points in both the north and south boundary zones.
On December 26, 1975, a proces-verbal was signed on specific issues. In paragraph 1, it states that "In connection with the description of the border line between boundary marks Nos. 101 and 101/1, it has been agreed that the border line passes midway between two springs both called Tchiftekan." In paragraph 2, it states that between boundary marks Nos. 81 and 82, the boundary "goes around all the currently existing orchards, thereby leaving them in Iranian territory."
III. ANALYSIS OF ALIGNMENT
Shatt al Arab
The boundary in the Shatt al Arab follows the thalweg for 105 kilometers (65 miles) starting at point R (29º 51.20'N., 48º 44.68'E.) "on a straight line joining, at the astronomical lowest low water, the extremity of the banks at the mouth of the Shatt al Arab." It continues upstream, passing through 59 additional points indicating the course of the thalweg. Point 59 (30º26.90'N., 48º06.62'E.) is at the junction of the thalweg of the Shatt al Arab and the Nahr al Khaiin
The Protocol Relating to the Delimitation of the River Boundary between Iran and Iraq, signed on June 13, 1975, was accompanied by four British Admiralty charts, on which the thalweg4 and points (determined by geographic coordinates) were plotted by a Joint Technical Commission as follows: (1) Entrance to Shatt al Arab (No. 3842); (2) Inner Bar to Kabda Point (No. 3843); (3) Kabda Point to Abadan (No. 3844), and Abadan to Jazirat Ummat Tuwaylah (No. 3845). Paragraph 4 of Article 2 in the protocol made provision for the boundary to continue to follow the thalweg in the event "of a shift of the bed of the Shatt al Arab or its mouth caused by natural phenomena." In Article 6, it was agreed that a new joint survey would be made of the Shatt al Arab at least every 10 years.
Article 7 of the same protocol provided for the freedom of navigation for Iranian and Iraqi vessels "regardless of the delimitation of each country's territorial sea."
Shatt al Arab to Turkish Tripoint
The land boundary is 1,353 kilometers (841 miles) long and is demarcated by more than 730 pillars numbered from 1 through 125/12. Annexes to the Protocol Relating to the
In Paragraph 1 of Article 2, the thalweg was defined as "the median line of the main navigable channel at the lowest level of navigation."
