Study on the diameter design method of vortex settling basin for suspended sediment based on the tangential characteristic Reynolds number.

ABSTRACT: The vortex settling basin for suspended sediment is a sediment treatment device that enables efficient use of irrigation water, yet the diameter design remains insufficiently defined, leading to large dis crepancies between measured and designed trapping efficiency in practice. This study proposes a diameter design method based on the tangential characteristic Reynolds number. Field observations were first conducted at three representative projects-Donglei, Talan River, and Shangmaxiangdi. Guided by these observations, laboratory physical models were developed, and an Acoustic Doppler Velocimeter was used to measure and analyze the distribution of tangential characteristic Reynolds number in each basin. The results show that when the sediment trapping efficiency is high, the tangential cha
