Abstract: A comprehensive reconstruction method for long-series sediment data in data-lacking areas includes steps of: collecting hydrological and sediment data of a target river section; calculating sediment data in data-rich years with a flow-sediment content annual relationship curve method; calculating sediment data in only water quality and sediment test years with a correlation method between water quality and sediment data and hydrological station sediment data; calculating sediment data in data-lacking years with an adjacent station same year flow-sediment content relationship curve method; and calculating sediment data in remaining years with a multi-year average flow-sediment content relationship curve method.

Abstract: The present disclosure provides equipment for riverway model manufacturing, including a framework assembly, a supply assembly, a rail driving assembly, a detection assembly, and a control device. A pipe chain conveyor is used to transport model sand into a second rail; topographic data corresponding to a riverway is input into a controller; the controller controls, according to the topographic data, a driving assembly and a supply assembly to discharge a material; meanwhile, a compaction device compacts the model sand; a detection assembly detects a height of the riverway model in real time; and after a predetermined height is achieved, manufacturing of next topography is performed. The problems that the current riverway model manufacturing has high labor cost, the model manufacturing is laborious, and the working intensity is high are solved.
