The Real-Time Monitoring of Narendra Nagar Landslide uses various geotechnical instrumentation for the landslide investigations aimed for developing Early Warning System (EWS). The total area of Narendra Nagar landslide site to be covered for monitoring is approximately 0.25 km2.
The real-time monitoring of landslide prone hill slopes involves monitoring plan that not only provide immediate warning of landslide activity but also provide understanding about dynamics of slope failures.
Typical real-time landslide monitoring systems consist of following:
Encardio-rite got the contract for complete monitoring works that included:
The geotechnical instruments included:
Location of the instruments were at three levels on the mountain i.e. at the crown, mid-level and toe. Drilling and installation of at all the three locations in the slopes was a difficult task, especially at the toe. However, all the instruments were installed successfully and are giving reliable data at pre-set frequency.
Monitored data was available online through Encardio-rite’s in-house developed DRISHTI, a web based data management system. The data was available in near real time to the stakeholders on their laptops and mobile phones.
Landslide hazards rank high as they pose a threat to life and livelihood, property, infrastructure and cause large-scale destruction in the mountainous region of India. The potential landslide areas may take a toll on human lives in the near future and cause damage to the residential and commercial areas and infrastructure.
