Analysis Of Water Power On The Affecting Tide And Branch Breach And Study Of Engineering Application

The factor of water power is a mostly ingredient of evolvement shallow to effect. On the instance of sand factor to shallow evolvement being feeblish , The analysis of water power is especially important. As a result of both direction current of tide reach , The evolvement rule is even more complex to the one direction current of reach ,and that locating branch reach of tide flow ,The characteristic of current is all the more complicated.This thesis studies and analyzes the influence water power factor to the shallow beach evolution in the runoff and tide bi-directional current condition and in the branch edge condition by the case of reach on the Affecting Tide and Branch Breach at Liu Zhang continent's Shallow Section of Tanjiang River. Moreover putting forward the project of renovating engineering on the basis of water power's analysis as well as becoming shallow's characteristic.finally after the process of deriving two-dimensional current equation,establishing hydraulic mathematics model by utilizing commerce software FASTTABS, and processing numerical value simulation.Ultimately putting forward excellent project. The findings indicates that1.The reach tidal current's characteristics is very intricate.that is differ on the tidal current route about eat and flow ,even flood tide is very strong , its endured the influence of two-direction flow at dull season but one-direction flow at flood season;just its appeared two diffluence ora between tow river center continents.2.The mostly causation come into being shallow for tidal current's goring ang pleading,branch river model ,the sand coming from lower reaches of a river along with the emergence of dispart flow mouth between Liu-Zhang continent and Sha-Huang continent.3.To the first project,the lock dam at the right branch of Liu-Zhang continent employed change of flow form on ascending and lower reaches of lock dam and on left branch of Liu-zhang continent.At the same time, the lock dam influenced the river part circumstances and the safety shipping in main sea-route.4.To the second project ,utilizing the arrange dam jammed the diffluence mouth secondly,the investment is the least and the punished effecting is evidence sothat lastly confirm the second project for excellent project.
