Abstract

<p> In the Ichinomiya River basin, a flood control project has been promoted, but observed data such as water level and flow discharge in rivers are not enough to understand hydraulic and hydrological features in the basin. In this study, we observed water level at multiple locations in the Ichinomiya River basin and showed the relationship between rainfall and water level. As a result, we indicated that the water level hydrograph in the main river depend on the confluence of tributaries. In addition, the HWL rainfall amount equivalent to the designed water level in the main river was generally higher than that in tributaries and was different even in the main river, suggesting the differences of flow capacity at each locations.</p>
