Popis:	This paper shows a prediction method of soil sediment shape when hopper-barge dump at the sea bottom. This prediction system is developed for the second construction of Kansai International Airport. Firstly model shape of sediment is applied to hydraulic model tests. Secondly model shape of sediment is applied to site data, therefore shape of sediment is different each of dumping vessel. Shape of sediment is classified at single peak and double peak. Difference of sediment shape is mainly caused by bottomdoors type, full-open and bottom-open. And sediment shape is also different of 3 type dumping method, full-dumping, time-delay-dumping and part-dumping. Shape of sediment model is composed of 1000m3 volume. Dumping volume is adjusted to sediment height. This prediction system is used of reclamation work at Kansai Airport. Accuracy of this system is sufficiently.
