The setting velocity of coral sand in liquid is an important physical quantity reflecting sediment movement characteristics.However,due to the different shapes of coral sand,the existing formulas for calcu-lating setting velocity are not suitable.Based on A series of single particle settlement experiments have been carried out for three typical shapes of coral sand,namely rodlike,platy and blocky sand.Based on the experi-ment data,the settlement characteristics of coral sand with different shapes are analyzed and compared with the results calculated by various theoretical formulas.After select...
