Friends here i made the gates of the water pipe channel on the reservoir side because of lack of machinery but it should be on the coastal side of the sea. The water pipe channel has already filled with water because the gates are present on the reservoir side. So i had to open the gates before the formation of tsunami wave to remove the extra water of the channel as you saw in the video. We can use the "Early Detection System" for the opening & closing of the gates of the water pipe channel to prevent tsunami. THANK YOU FOR WATCHING...
