The Assessment Study On The Current Situation And Availability Of Rushankou Tidal Energy

The tidal energy development and utilization of computing the amount of contrastand different positions and sluice gates set mode settings tidal flux and energy iscalculated with the numerical model by using Finite-Volume Coastal Ocean Model(FVCOM) in the Rushankou, merit comparison is made by calculating tidal powerinstalled capacity, the annual generating capacity, generating hours and so on. Themodel was tested through field observation data, and the results are objectively true.The results are that tidal amplitude decreases in the area of the dam after built the dam,the influence delay spread of S2is significant; due to the barrier of the dam, flow ratedecreased, maximum flow rate reduced up to30cm/s, and a jet formed in thewaterway into the spindle Bay, the maximum flow rate of up to340cm/s; the overflow intensity increases, the mouth of the bay to the east and the west fork of thebranch channel regional distribution of two radii roughly equal, opposite the directionof rotation of the vortex flow field; switching cycle time is extended to30days andresulted in the outer Bay regional water exchange rate decreased; basically no erosionintensity changes within the gulf after the dam. However, a larger change in thedistribution of high concentrations of suspended sediment is limited to the waters nearthe construction, does not constitute a wide range of marine environmental impacts.
