| Research Abstract |
Republic of Palau has two development strategies. One is the increase in the population by attraction of foreign company. For these purposes, development of a residential section and a company lot are needed. The change of land use pattern will induce the increase of clay runoff and affects to natural environment and coral reef. We measurements were made continuously for two years to estimate the red clay runoff discharge from land development area. As a result of estimating the amount of sediment discharge from developed area, it was the amount of sediment discharge of about700 t/ha/yr. This amount was corresponding to model calculation.Moreover, we also were discussing the environmental acceptable capacity and the number of tourists from the point of view of natural environmental preservation.
