  Dear Netherlands Staff,
  Thank you for your reply, and we really understand your difficult situation.
  As of present, we cannot decide when we will be able to visit the Netherlands in the future.
  So, we would like to choose the voucher option.
  Thank you for your sincere efforts.
  Respectfully,

Abstractの修正

( 修正前 ) SBTs are a leading technique to mitigate reservoir sedimentation. SBTs consist of a tunnel connecting the upstream and downstream areas of a dam and diverting sediment-laden flood directly during flood events. A difficulty in operating SBTs is to reduce sediment inflow into the reservoir effectively, and at the same time, to sustain the dam functions: flood control and hydropower generation. These requirements settle on an optimization problem determining the timing to open and close the SBTs gates with the hydrograph and inflow sediment considered. Despite many studies on SBTs operation considering hydrograph, there are few of those on the temporal change of sediment inflow. Accordingly, this study aims at improving SBTs operation by understanding sediment inflow from upstream reaches using an indirect bedload monitoring system called impact plates. For that, the Koshibu Dam SBT was picked up because impact plates are already placed in several locations in the basin including inside of the SBT. This observation has revealed the amount of transported sediment in every season in a year, the relation between hydrograph and sediment inflow, and the spatial transient of sediment transport peaks. According to these observations, desirable rules for SBTs operation are suggested.

( 修正後 ) SBTs (sediment bypass tunnels) are a leading technique to mitigate reservoir sedimentation. SBTs consist of a tunnel connecting the upstream and downstream reaches of a dam and diverts sediment-laden flood directly during flood events. A difficulty in operating SBTs is to reduce sediment inflow into the reservoir effectively, and simultaneously sustaining dam functions such as flood mitigation and hydropower generation. To optimize the problem in controlling the timings required in opening and closing the gates in the sediment bypass tunnels (SBT) (,which) are governed by the hydrograph and inflow sediment data. Despite many studies on SBT operations considering hydrograph, there are few of those on the temporal change of sediment inflow. Ultimately, this study aims at improving SBT operations by understanding sediment inflow from upstream reaches using an indirect bedload monitoring system called an impact sensor. For this study, the Koshibu River basin was chosen because impact sensors are already placed in several locations around the basin including inside of the SBT. This observation has revealed the amount of transported sediment during each season in a year, are shown with relations between hydrograph and sediment inflow, and the spatial transient of sediment transport peak levels. According to these observations, desirable rules for SBT operations are suggested.

• I was not very busy today due to all my students submitting their papers.
• My workload is much less than usual.
• a lot on my plate/ I had nothing on my plate.

( 修正前 ) The use of dams for multi purposes is earning more attention and hence the importance of them in society increases. This situation naturally requires strategies to mitigate sedimentation to prolong dam lifespan. ( 修正後 ) Dams play an important role in society and has multi purposes, hence the situation naturally requires strategies to mitigate sedimentation to prolong dam lifespan.

lifespanは人・物何でも使える. the lifespan of dams, dam's lifespan, dam lifespan全て自然.
