Abstract
In this study, we confirm accuracy of velocity and discharge evaluated by a dynamic interpolation and extrapolation (DIEX) method which has been developed by the authors. We here apply the present and conventional methods to evaluate cross-sectional velocity and discharge from point velocities of simulated float data. The results indicate that the DIEX method has high accuracy for discharge evaluation from point velocities even when spatial resolutions of velocity data was low, showing wide applicability of the DIEX method. The results also revealed that the accuracy of the conventional method for discharge evaluation was also high when spatial resolutions of velocity data was high and appropriate coefficient of float was used.
