2022 India–Bangladesh floods
Beginning in May 2022, deadly floods hit northeastern India and Bangladesh. Over 9 million people in both countries have been affected, and around 300 people have been  killed. , millions of people across the affected areas are reported to be in urgent need of food and medicine. Background 

Bangladesh and northeastern India, especially Assam, are mainly flat floodplains with numerous rivers flowing across them, the most prominent of which are the Ganga (called Padma in Bangladesh) and Brahmaputra (called Jamuna in Bangladesh). Other major river systems in the region include the Barak-Surma-Kushiyara river system, which flows through northeastern Bangladesh and the Barak Valley of Assam. Due to the large volumes of water coming from the Himalayas and the heavy monsoon rains, flooding is a regular occurrence in this region. At the time of the floods, a La Nina event was active in the Pacific meaning India and Bangladesh would receive heavier monsoon showers. Beginning in May 2022, deadly floods hit northeastern India and Bangladesh. Over 9 million people in both countries have been affected, and around 150 have been killed. [1][2]

Around 40% of Assam's area is a flood plain, which is also roughly 10% of India's total flood-prone area. According to ISRO, nearly 30% of Assam's land area have been flooded at least once from 1998 to 2015. Heavy rainfall and settling of sediments plays a major role in rising the water level of the Brahmaputra river and its tributaries. Also, according to a survey, the Brahmaputra have widening yearly due to erosion, which also makes the flooding worse. Events
