| The statement added that both sides reached to understandings on Shatt-al-Arab water way through adopting the Thalweg river line principle. |
| The thalweg has been frequently confirmed as the accepted boundary where no conventions to the contrary existed. |
| Usually, borders that follow rivers run along the center of the river's main navigable channel, what international law refers to as the thalweg principle. |
| The work also includes levelling the bottom of the secondary channel along the river's right edge to establish a thalweg slope allowing fish to move freely. |
| In a river whose thalweg constitutes the boundary between two States fish are constantly moving from one country to the other. |
| Following the thalweg along its many twists and turns, the riverine border adds up to about 95 miles. |
