Case Study - Ganges/Brahmaputra River Basin
Flooding is a significant problem in the Ganges/Brahmaputra river basin. They cause large scale problems in the low lying country of Bangladesh. There are both human and natural causes of flooding in this area.

Human Causes
Deforestation - Population increase in Nepal means there is a greater demand for food, fuel and building materials. As a result deforestation has increased significantly. This reduces interception and increases run-off. This leads to soil erosion. River channels fill with soil, the capacity of the River Ganges and Brahmaputra is reduced and flooding occurs.

Natural Causes
Monsoon Rain
Melting Snow
Tectonic Activity - The Indian Plate is moving towards the Eurasian Plate. The land where they meet (Himalayas) is getting higher and steeper every year (fold mountains). As a result soil is becoming loose and is susceptible to erosion. This causes more soil and silt in rivers. This leads to flooding in Bangladesh
