Introduction
Floods in Bangladesh are a natural devastating phenomenon. They affect millions of individuals yearly. These devastating floods are primarily caused due to Bangladesh’s unique geographical location. The country is located in the delta of the Ganges, Brahmaputra, and Meghna. It is characterized by its low-lying geography and expensive river network. This specific characteristic makes the country vulnerable to floods, especially during the rainy season.
Causes of Floods in Bangladesh
Bangladesh’s geographical location plays a noteworthy role in its vulnerability to flooding. The country is predominantly low-lying. It is situated at the junction of three major rivers: the Ganges, Brahmaputra, and Meghna. These rivers carry vast amounts of water from the Himalayas and encompassing regions. The water from them meets in Bangladesh and frequently floods their banks during the monsoon season. The broad river network and the deltaic landscape make it difficult for the overabundance of water to deplete quickly, leading to flooding.
The climatic conditions in Bangladesh further assist worsen the flooding problem. The country experiences heavy monsoon downpours from June to September, which contribute to the swelling of rivers and consequently flooding. Furthermore, the melting of snow in the Himalayas during the summer months increases the volume of water flowing into the rivers. This combination of heavy rainfall and snowmelt altogether raises the water levels in the rivers, often resulting in serious floods.
Human activities have moreover contributed to the increased recurrence and severity of floods in Bangladesh. deforestation in the upstream regions reduces the land’s capacity to absorb water, leading to higher runoff and expanded river flow. poor urban planning and fast, unplanned urbanization have led to the construction of buildings in flood-prone zones worsening the impact of floods. Inadequate drainage systems in cities and towns prevent the efficient removal of excess water, causing urban flooding. Additionally, the construction of embankments and dams, while intended to control floods, can sometimes lead to unintended results, such as the alteration of natural water flow and increased flood hazard in other areas. These topographical, climatic, and human variables collectively contribute to the frequent and devastating floods in Bangladesh, posing critical challenges to the country’s advancement and well-being.
