Q1. Indus river discharge is highest in summer mainly because of melt from which high mountain source region?
Answer: Karakoram and western Himalaya snow and ice
Explanation: The Indus River system reaches its peak discharge in summer (June–September) primarily due to snowmelt and glacial melt from the Karakoram and western Himalayan ranges, augmented by monsoon rainfall at lower elevations. This glacial contribution makes the Indus unusual among the world's major rivers and crucial for Pakistan's irrigation-dependent agriculture during the dry Kharif season.
