Context: Recently, a glacial lake outburst in north Sikkim's Mangan district, caused flash floods and breached Sikkim's Chungthang dam, the state's largest hydropower project.
Flash flood
o It can occur even if no rain has fallen, or after a sudden release of water by a debris or ice jam.
o It happens more where rivers are narrow and steep, so they flow more quickly.
o It can occur in urban areas located near small rivers since hard surfaces such as roads and concrete do not allow the water to absorb into the ground.
o Heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields.
o It also occurs due to Dam or Levee Breaks, and/or Mudslides (Debris Flow).
o Occur on or near volcanoes, after eruptions, when glaciers have been melted by the intense heat.
