The paper summarizes feasible series techniques in the formation of lower river bed through irrigating sedimentation in lower reaches of Yellow River on some issues, i. e., water drawing, sedimentation,sediment digging out,sediment delivery,dyke construction through sedimentataion and operation,organization and management,and so on. These techniques include design and calculation method on sediment delivery,sediment silt channel and chamber,mathods for sediment digging out, machine sellection and forming a complete sets, sediment delivery techniques,and dyke building through sedimentation. As these techniques are cooperated very well,convenient for application,and possible to meet the demonds for lower river bed formation design and construction without influencing the existing Yellow River irrigation system.
