The dispersion situation of the small particles in the high turbidity waters from sea sand mining boat was calculated using a simple numerical model. The transparency (Secchi disk depth) decreased remarkably near the discharge spot of high turbidity waters. When the operation of sea sand mining at intervals of two days was repeated, it was clear that the influence area of high turbidity waters spreaded widely. To suppress influence of sea sand mining in a minimum, it was suggested that the operation of sea sand mining at intervals of five days and above should be done.
