Multiple Linear Regression Analysis of Vertical Distribution of Near-Shore Suspended Sediment

According to some main assumptions in the Rouse Formula, it analyzes the applicability of Rouse distribution in the coastal region. Based on the classical Rouse Formula, the linear form of Rouse Formula and the transport characteristics of offshore sediment were used to takelnzh,lnca,ca,u,lnu andzh as the independent variables. The multiple liner regression method was used to analyze the influence of the independent variables on the vertical distribution of sediment concentration. By using the method of significance test, the factors (lnu) that have less influence on sediment concentration among 6 variables were eliminated. The correlation coefficient between the calculated sediment concentration and the measured sediment concentration indicates thatthe adopted variables can reflect the characteristics of vertical distribution of concentration of fine sediment near shore under complex dynamic conditions.
