THE IMPACT OF THE OROGRAPHICAL FACTOR ON THE DRAIN OF THE DISSOLVED SUBSTANCES OF THE PLAIN AND MOUNTAIN RIVERS OF THE WORLD

Денмухаметов Р.Р.
In article the impact of a relief on a drain of dissolved substances of the plain and mountain rivers of the world are considered. Оn plains the drain of the dissolved substances increases at a re-course from lowlands and heights to the flat rivers with a source in mountains. In mountains of the maximum values of a drain of the dissolved substances are dated for high-mountainous river basins. It is established that, on average, mountain rivers carried dissolved material in 1.6 times more than plain rivers. The minimum values of a drain of the dissolved substances are dated for lowlands. In mountains maxima of a drain of the dissolved substances are confined to the high-mountain river basins. For the mountains has a more variegated lithological composition of rocks and high intensity of water exchange. With increasing altitude catchment weakly stable degradability sedimentary carbonate and sulfate rocks exposed denudation more than crystal and sedimentary terrigenous rocks. More intensive chemical destruction of the mountains also contribute to fractures, tectonic conditions.
