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.
