Essay on disaster management in Uttarakhand
Answers
Explanation:
1. Base line data on Natural Resource Conditions, Landslides, Fissures, Cracks, Potential Blocked Sites and Landslide Hazard Zonation (LHZ) needs to be identified in the entire Uttrakhand or Himalayan States using high-resolution satellite data. 2. Considering that majority of slope failures along the roads and the villages occur during the monsoon. In view of this, the above geomorphic features need to be monitored on regular basis in order to evaluate their susceptibility. This study should be undertaken at micro watershed label preferably at cadastral level or 1:12,500 scale. 3. Like Uttarakhand most of the states lack widespread meteorological stations, hence data pertaining to rainfall, snow avalanche, wind and temperature are illusive. For an effective mitigation planning meteorological data provide significant insight towards understanding the causes of slope failure or flash floods. For example in Uttarakhand, the mean annual rainfall of the region is around 1500 mm and we will find that in years when calamity like 1970 Alaknanda flood or 1998 Madhymaheswari landslide (Benti and Paundar), it was not the increase in mean annual precipitation but the duration of rainy hours. It is therefore, essential that number of such station should be increased taking into consideration the geographical variability. There is a need to create village label disaster mitigation units involving, youth, women and school children
