The Study Of Xinjiang Manas River Channel Gravel Bed Load Transport Rate

Sediment problem is the world's major problems of common concern to address the canals sediment disaster is water over the years, workers in research problems. Sediment disasters have rivers, reservoir sedimentation, land desertification, lake, city, or building and engineering facilities have been scouring sediment and other manifestations of destruction, river sediment disasters, China is the most affected countries, annual sediment losses of 100 billion in orders of magnitude.As early as 1879 the French Duboys bed load movement proposed theory of drag force and the establishment of bed load transport rate formula. Since then, scholars from different angles, with different water-based mud factor, there have been new theories and formulas proposed. Present calculation formula for bed load transport rate, not only the basis of very different argument, the structure and form of the formula is varied, according to incomplete statistics, at present a variety of bed load transport rate formula for more than 50.Most of the rivers belong to the Xinjiang river. Seasonal changes in river runoff in large river flood flow, the river sediment is relatively large. How complicated bed load transport rate formula for selecting one or more of mountain rivers in Xinjiang, gravel bed load transport rate formula, the paper will be based on a typical mountainous river in Xinjiang-the Manas river, bed load transport rates measured information on the part of the pebble bed load transport rate formula for checking, and correct the Levi equation, derived a new formula can be applied to select the Manas river gravel bed load transport rate formula. Sediment Transport under the sand to take corresponding measures for water management of headworks scientific operation, to prevent the bed into the trunk, reducing sediment damage; to turn sand-type headworks measures provide a theoretical basis for river training works in Xinjiang, disaster prevention and control of sediment laid the foundation for the promotion of agricultural water saving technology to provide protection.
