The validity of hydraulic computational results is closely related to the observed information and the analysis model. However, there are few study cases relationships between the density of observed data and the accuracy of computational results.
In this paper, by using the elevation of numerical computational mesh in the general coordinate system which was made from three different densities measured by ALB, we discuss the measurement density of elevation for hydraulic computational analysis. Next, it was shown that the estimated hydraulic values and identification parameters to data assimilation in a Tone River reach changed according to the difference of the space density of the observation sites of the water level during the flood in October, 2017. We discuss the space layout of observation site for the data assimilation to the time-varying longitudinal water level distributions.
