In the case of the recent flooding, the precipitation centre that caused it is in Tripura. As a result, the areas surrounding Tripura are experiencing severe floods. Brahmanbaria is situated to the south of Tripura, while Moulvibazar and Habiganj are located to the east.
This situation has led to widespread flooding across these regions. The intense precipitation in Tripura has caused several rivers to overflow. Some rivers have flowed towards the south, some to the north, and others to the southeast, creating an unusual situation.
Rivers in Bangladesh typically flow from the north to the south towards the Bay of Bengal, but that is not always the case. For example, the Gomati River flows from the eastern side of Tripura, through the Dhalai district, passing between two mountain ranges. There is a dam on the first mountain range, where water is collected to produce electricity. Such reservoirs are also used as flood control mechanisms. In the event of heavy precipitation, the dam gates can be opened slowly to release some water, but this has a limit. When the water exceeds this limit, the dam overflows, leading to flooding.
However, the flooding is not solely due to the dam overflow. For instance, the Khowai River originates in Tripura, and there is a barrage at its mouth. There is also a barrage at the origin of the Gomti River. These barrages don’t hold much water, so opening or closing them does not directly cause flooding. The flooding is more connected to the opening of gates at the Teesta River, which is connected to the Ganges and the Farakka Barrage. These barrages can hold a significant amount of water, and when they are opened, the heavy flow contributes to flooding downstream.
This time, the flooding was primarily caused by excess rainfall. The army, when mobilised with proper resources and coordination from the state, can play a crucial role in managing such disasters by providing logistical support, such as speed boats and other necessary equipment. However, the current government, being newly in power, may not be fully prepared to take immediate and decisive action. Instead, it is engaging in heavy rhetoric, often adopting an aggressive stance toward India, which is not the right approach.
The situation should be handled diplomatically, with a proper understanding of the hydrological dynamics of the Ganges, Teesta, and other rivers. A well-informed strategy is essential. The government should consider ratifying the United Nations Watercourses Convention of 1997, which has been pending in Bangladesh for a long time. This could be a significant step forward. The interim government’s adviser on environment and water resources, Syeda Rizwana Hasan, has suggested taking the river sharing issue onto international platforms, but to do that, Bangladesh first needs to ratify the convention, as going to the UN without accepting the convention will not be effective. Some have alleged that the previous government did not accept the convention due to India’s influence, but this government should not adopt the same stance.
As for our roles as ordinary citizens, first, we must refrain from panicking, as difficult as it may be. In situations like this, panicking can often cause further trouble. People who have their own families to look after should treat them as a first priority. Apart from that, individuals whose families are not dependent on them may engage in volunteering in the flood-affected areas, if they have a financial surplus or can collect funds for flood relief.
