Hill Cart Road
Landslide Monitoring is an important and integral part of landslide investigation as
well as landslide management. The major objectives of landslide monitoring system
are:
To provide information that can assist landslide investigation and analysis.
￿
To determine the rate of change of the areal extent of the major landslide
location in the watershed.
￿
To identify the link between ground movement, rainfall and ground water that
can promote slope materials to move downward.
￿
￿
To provide early warning in the landslide affected areas mainly at Paglajhora,
Shiviter and Tindharia where movements could affect life and property.
To monitor the effectiveness of landslide management strategies taken along the
Hill Cart Road.
In a number of unstable locations, where monitoring has taken place over several
years, a monitoring strategy has been established which includes the gathering of
information on both meteorology and ground movements. Increasingly taking into
account the cost of manual data gathering, electronic systems are being used,
allowing easier data acquisition, interpretation and storage (Fort et al. 2000 ). It is
generally observed from the previous experience that after the destruction of slope
by landslide, emergency attention is given to the affected areas and huge amount is
spent for the restoration and rehabilitation. It can be suggested strongly for regular
monitoring of the potential failure area and a little precautionary measure may save
the slope as well as huge property from destruction.
