In order to alleviate the dredging pressure of Shenhua Huanghua Port and reduce the cost of dredging,we carry out a feasibility study on the application of navigable depth in the harbor basin and inner channel of Shenhua Huanghua Port.Based on the test of density,particle size,hydraulic characteristics and rheological behavior of the sediments in the inner channel and the basin,we demonstrate the feasibility of applying navigable depth,and put forward the navigable silt density value of the basin and inner channel of Shenhua Huanghua Port.Furthermore,by investigating the distribution of navigable resources,we analyze the key areas and prospects of applying navigable depth to provide a basis for guiding the utilization of navigable depth in Shenhua Huanghua Port.
