Principle purpose of this lecture is to presentation on Coastal Flooding in Bangladesh. Bangladesh is widely recognized to become a country most affected simply by global climate change. Coastal inundation caused by sea levels rising and extreme coastal flooding could potentially cause saline intrusion into aquifers. Bangladesh is struck by way of severe tropical cyclone on an average of every three years. Global Climate Change is predicted to increase the frequency of these kinds of floods. Almost every year these floods result in a significant amount of damage and loss of life in the parts surrounding the rivers where crops including rice are grown.
