Assam receives high rainfall during the monsoon season, and the rainwater flows from the neighbouring Himalayas, causing the rivers to swell and burst their banks in a short time.
Assam has a vast network of rivers, including the Brahmaputra and Barak rivers and over 50 tributaries, which cause flood devastation during the monsoon period every year.
The Brahmaputra and its tributaries erode much area of land annually, increasing the width of the river and causing more devastation in the surrounding areas.
The rivers contain a large amount of silt and debris, which increases the water levels. This makes the river more deep and dangerous, especially in the monsoon
Human activities like deforestation and hill cutting contribute to landslides and soil erosion, which have increased flooding over time.
Inadequate drainage and unplanned urban growth in the region worsen the flood situation in urban areas.
The river is so vast and gets so dangerous in the monsoon season that there is no fixed pattern of its flowing, it gets unpredictable every year
