3D laser scanner was applied for measurement of 3-dimensional shape of the landform of riverbed of Kinu River. The results show that the 3D laser scanner can measure the 3-dimensional shape of the landform of the riverbed shape with good accuracy. The riverbed deformation of the local scour around the bridge pier was also calculated. The result shows that accumulation and scouring distribution around the bridge pier in detail. These results show that the 3D laser scanner is able to use for river engineering by measurement of 3-dimensional shape of the landform of riverbed. Measurement of the landform under the water was indicated as problem in the future.
