The rate of scour is clearly very fast and the lake level is still very high indeed (it has apparently dropped 10 m). CCTV has just reported that the smaller dams downstream have now been overtopped and washed away.

The slide dam failed at its toe, and the uphill part of the slide mass is still saturated, and worse, its toe is being swept away. There will probably be a failure of the whole hillslope before this is over.
ReplyDeleteThe channel bank is very steep. The failure of left or right banks (landslide mass) may again block the channel flow. If it happens it will help to reduce the outflow discharge.
ReplyDeleteWater level of lake is 734.3m at 12:00, discharge is dropped to 5200m3/s from 7300m3/sec (at what time??).
