The thalweg principle is the principle of determining National Boundaries at the thalweg of a River separating two State s. The precise drawing of river borders has been important on countless occasions; notable examples include the Arvandrud/Shatt Al-Arab between Iraq and Iran , and the Danube in central Europe . A thalweg in Geology is a line representing the profile of a land surface, drawn as a series of cross-sections that crosses all contour lines at right angles. The word thalweg is also used in Hydrology . It refers to a line drawn to join the lowest points along the entire length of a streambed or valley. This is occasionally called a ''valley line''. The term is also sometimes used to refer to a subterranean stream that percolates under the surface and in the same general direction as the surface stream. |
