The influence of slope factor for the construction of sandy shoal in the lakeshore zone

In order to clear and define the influence of slope factor for the construction of sandy shoal, the research presents developmental process of sandy shoal through flume simulation from the perspective of sedimentology forward modeling. The experiment is divided into three groups by using the method of control variable in the can wave flume device. The condition such as waves, source remains unchanged, and changing slope of every group, the tangent of three slopes is respectively 1/15. 1/20. 1/25. The experimental results show that the developmental degree of sandy shoal in the lakeshore zone is better, the thickness is larger as the slope increases; the scale of the bar is smaller as the slope decreases, because the waves cannot hit the bottom shape. The marginal slope value where the scale of the bar changes obviously is 1/20. The research this time studies the influence of slope factor for the construction of sandy shoal in the lakeshore zone from the angle of sedimentology through quantitative flume simulation experiment, providing a reference for the further research of shoal.
