New Exploration of Reservoir Capacity Regeneration Technology for Sandy River from Systematic Perspective of the Basin
Based on the water and sediment regulation and silt reduction,a new storage capacity regeneration strategy of"flushing silt through the channel and driving sediment into the sea"for reservoirs on sediment-laden rivers was proposed to address the issue of large-scale siltation and storage capacity regeneration in wide beach areas of reservoirs.On the basis of hydraulic dredging technology,in order to achieve the simultaneous treatment of erosion and sedimentation in the channel and beach,engineering measures and modular equipment were ex-plored to separate and control the water flow in the reservoir area,enhance the self power and sediment carrying capacity of the water flow,and flush the high beach sediment into the main channel and the sediment funnel in front of the dam,and then bring it out of the reservoir through water and sediment regulation,achieving the goal of driving sediment into the sea.Systematically it solved the issue of sedimentation in existing reservoirs on sandy rivers,and provided theoretical and technical support for the design of planned reservoirs for sediment flushing.
