Validation of Sediment Transport Model Using Hydraulic Experiment Data to Assess the Influence of Grain Size and Reflection Wave on Tsunami Deposit

To improve tsunami prediction, it is important to consider paleo tsunami records. Tsunami deposits can provide many paleo tsunami records; however, the formation mechanism of tsunami deposits remains unclear. Furthermore, numerical analysis focusing on tsunami sediment in the inundation area has fewer verification examples. Therefore, in this study, we conducted hydraulic experiments to elucidate the formation mechanism of tsunami deposits. The hydraulic experiments considered the influence of grain size and reflection wave. In addition, we investigated the characteristics of sand deposits depending on sand composition and topography (i.e., natural embankment). It was confirmed that the amount of sand deposit decreased toward the top of the run-up area. However, for the case of mixed sand which has several grain sizes, it was found that the mixing ratio influenced the composition ratio of the sand deposit in the middle of the slope area. For the case of the reflection wall, it was observed that characteristic sand deposits were formed by the return flow. We evaluated existing sand transport models using the obtained data. The results of the numerical experiments confirmed the high reproducibility of the existing models for the case with the return flow (i.e., with a reflection wall). However, for the case without return flow (without a reflection wall), it was clear that reproducibility was affected by grain size. Furthermore, it was confirmed that the amount of sand deposit was overestimated near the top of the run-up area. Thus, we considered some problems of overcome this model.This study was supported by JSPS KAKENHI Grant Number 17H02060.departmental bulletin pape

STM Observation of Au Particles Adsorbed on Si(111)-Clean Surface by PLD Method

To obtain important information for fabricating atomic-scale Au thin films that are used for biosensors, we have examined the flushing temperature for forming the Si(111) clean surface and observed the morphology of Au particles adsorbed by Pulsed Laser Deposition method on a Si(111)-7×7 surface by STM, which is supposed to be the initial stage of Au atomistic thin film formation. As the result of this study, it was found that flushing temperature must be controlled within 5℃ and we can fix the flushing requirement by STM images. Besides, we have estimated that Au particles are adsorbed on the position which is about 0.21 ± 0.03 nm away from the center of Si adatom.departmental bulletin pape
