The Study Of Flow And Sediment Transport And Evolution Law On The Estuary Of Liaohe River

According to the field measurements of runoff,flood and tide at the Liaohe River Estuary, the paper uses the simulation of the sediment's movement disciplinarian which based on Hydrodynamic Force Model,and and analysises the evolvement law near the estuary. Compared with the actual condition of sediment transportation, we can see that the simulation results are quite close to the actural data,and the result is comparatively dependable.Athough the observed data in this area is scarce, the reversibility of the remote sensing data, the speciality and abundance of the observation prototype may recuperat the scarcity of these actural material's scarcity in the some degree. The paper uses the remote sensing analysis as the technical method, with the gathering and analysis of the basic data, integrated analysis of the on-the-spot investigation and an amount of remote sensing data, it tries to scarcity on the careful earnest analysis to the massive remote sensing material. Based on the analysis of the change of Liaohe River Estuary waterfront shallow seas and tidelands in the key point, the river potential change, the fluid flow characteristic, the sediment transport characteristic, the author has integrated the practical hydrology data, the river estuary geomorphology and the basic principle of hydrodynamics to analyze the evolvement tendency of Liaohe River Estuary and to verify mutually with the hydrodynamics simulation result. This result may provide a reliable theory basis on the government plan in this area for the next step.
