A team consisting of me (N.N.Rai, Director, CWC), Mr Piyush Ranjan, Director, CWC, Shimla, Mr Rohit Sharma, Asstt Commissioner, Keylong, Col Arun, Indian Army, Mr Sandeep Kumar Rawal, Inspector, NDRF, Mr Ramchandra Negi, Nayab Tehsildar, Udaipur visited the land slide site on river Chandrabhaga today (15Aug 2021) between 1 pm to 2 pm. We have found that more than 50% blockage has already got removed naturally by the river. The velocity of flow at the blockage location is in the range of 6 to 7 m/s.
Further, as can be seen in the photograph, due to land slide, a natural bench of about 20 m width and about 45 to 50 m length has formed which will provide the space to accommodate the material falling due to further land slide. The concave shape of the sliding plain shall also provide some space to accommodate the further sliding material. Hence, the further complete blockage of river in case of land slide at the same location is less likely.
The sliding material is having the majority of finer grain composition and any material further coming in the river will get washed away by the running water.
The situation seems to be normal at present, however the administration need to be watchful for further slide.
