Abstract

Developing technologies of Airborne Laser Bathymetry (ALB) have recently enabled us to obtain topographical data on river channels including underwater area. The reproducibility of river channel topography is estimated to effect on numerical analysis for river. However, there are few studies using ALB data, so the effect of it on analysis results has not been considered in particular.<br>In this study, the topography data obtained by ALB measurement is examined the accuracy. Furthermore, we studied the effect of the topography data on analysis by comparing results of river-bed variation analysis and the difference data of ALB measurement.<br>The topography data obtained ALB measurement showed the same topographical shape as cross-sectional survey result. In addition, by comparing analysis results and the difference data of ALB measurement, analysis using ALB data showed a trend similar to measured value than using conventional data.
