Describe mitigation measures of geological problems in Himalaya. [2072 Ashwin] [3]

Some of the geological problems of Himalayas are listed below:

• Landslides,
• Liquefactions,
  
• Debris flow,
• Slope failure,
• Earthquake,
• Flash floods,
• Rock falling and rock toppling.
• GLOF etc.

Mitigation of these Problems:

• various preventive (construction of retaining structures) and corrective measures (reduction of pore water pressure, slope reformation, protection of toes of slope from erosion etc.) can be applied to prevent landslides, creep flow , debris flow etc.
• The civil engineers must think of making his construction immune to earthquakes.
• flood can be controlled by planting vegetation, through the construction of leeves, lakes, dams, reservoir etc.. Moreover floodways can be constructed to divert floodwater.
• Various ground improving techniques like compaction grouting, dynamic compaction, vibro compaction, vibro replacement, wet soil ....
