RMSI Analyzes Potential Risks
To Life & Property of the Artificial Lake’s
Breach in Tibet
RMSI, a global IT services company, announced
today that their risk modeling division, having
a decade of experience in risk assessment studies,
has analyzed the potential risk of the artificial
lake formed on Pareechu river, a tributary of
Sutlej, in the Tibet region. The impact of flash
flooding along the banks of the river Sutlej in
Himachal Pradesh, triggered by the breach of the
landslide that blocked Pareechu, was analyzed
in terms of extent and depth of flooding, population
affected and property losses. Three potential
scenarios based on different depths of the breach
including the worst-case of full breach of 60
meters were analyzed.
“Due to the hilly terrain conditions and
the valley shape along the Sutlej, the flood extents
are not expected to go far from the river channel
but flood depths are expected to be very high.
In the worst-case scenario, flood extents up to
1.2 km and flood depths up to 20 m with averages
of ½ km and 10 m respectively are expected”,
said RMSI chief hydrologist Dr. Murthy Bachu.
As per Adityam Krovvidi, Head of Risk Management
Services at RMSI, the risk analysis is based on
an internally sponsored study involving development
of a flood model applying international best practices
and the following impacts could be expected in
the event of a flood caused by the worst-case.
- The flood damage is expected even at far off
places like Rampur that is 230 km away from
the lake. The flood depth on the banks at this
place is estimated to be about 5 m.
- About 5 lakh people are likely to be affected.
- Property worth Rs. 60 crores is estimated
to be at risk.
The study used Census 2001 data, published information
on the lake and other available in-house data.
RMSI conducted similar studies in the past including
2001 Gujarat earthquake and 1999 Orissa cyclone
vulnerability studies.
