Gorakhpur: Extreme Rainfall, Climate Change, and Flooding (Technical Report)

The report examines how the combination of rapid urbanization and climate change is increasing flood risks in Gorakhpur. It highlights that the loss of water bodies and construction in the floodplains of the Rapti and Rohini rivers have reduced drainage capacity. Projections indicate that climate change will increase the intensity of rainfall events by the 2050s, potentially increasing the intensity of small rain events by 10 to 20% and more severe 24-hour events by 2 to 25%.

• Urbanization is a primary driver of increased flooding and waterlogging in Gorakhpur, specifically through the loss of water bodies and construction within the floodplain zones of the Rohini and Rapti rivers, which impairs the city's ability to store, absorb, and drain floodwater.
• Climate change is projected to increase the intensity of rainfall events in the Gorakhpur area over the next 50 years, which, combined with unsustainable urban growth, will lead to increased flood depths and longer durations of waterlogging.
• Small rain events that currently cause flooding in specific areas, such as Mehewa Ward, may see an intensity increase of 10 to 20% by the 2050s due to climate change.
• The intensity of more severe 24-hour rainfall events is projected to increase by 2 to 25% by the 2050s under climate change scenarios.
