Summary:The system that flow and bottom topography were able to measured simultaneously was developed by using ADP, GPS and radio control boat. The bottom tracking function was used to measure flow and topography. The accuracy of vertical direction in this system is about 3cm. At the river mouth of Hiji river, this system was used to measure flow and topography around the sand bar. At flood and ebb tides, the circulation flow was verified off the sandbar. These flows around sand bar act to the trigger of the formation ofsandbar. As this developed system is simple and has the high accuracy, it is very useful to the measurement of flow and bottom topography.
