Dhaka, May 29 - A powerful tidal wave caused by a deep depression in the Bay of Bengal has inundated extensive low-lying regions in Bagerhat. This situation has brought difficulties for numerous inhabitants and poses risks to local wildlife as well as fish farming activities.
One of the victims is a deer discovered deceased within the Sundarbans region, whereas a young deer was saved after being carried off by flooding waters.
Intense rainfall coupled with a surge in tidal waters rising between 2 to 3 feet submerged crucial sections of the coastal area on Thursday, affecting urban regions such as Bagerhat town.
The roads in Sadhanar Mor, Rahater Mor, Main Street, Dakbungalow Mor, Nager Bazaar, and the central marketplace were inundated, causing disruptions to transport and impacting local enterprises.
The condition has deteriorated in the Sundarbans, with extensive areas of woodland submerged under floodwater. Wildlife such as tigers and deer are apparently struggling as they search for refuge from the rising waters.
The Forest Department reported that a deceased deer was found at Dublar Char, while a fawn displaced from Shelar Char was saved, treated, and then set free afterwards.
"The tide is flowing through parts of the forest at heights of 2 to 3 feet," said Md. Rezaul Karim Chowdhury, Divisional Forest Officer (DFO) of the Eastern Sundarbans Division. "We've instructed all forest staff to remain vigilant."
Rain disruptions caused by depression-linked rainfall disturb daily life in Chandpur.
Past the Sundarbans, tidal inundation has affected the areas of Rampal, Mongla, Sarankhola, and Morrelganj, where weak embankments have worsened the situation.
The Water Development Board has stated that 800 meters of embankments, notably in Sharankhola and Morelganj, are in severe danger. Should the water level increase by an additional four feet, a 10-kilometer section might break through, leading to flooding in nearby communities.
Abu Raihan Mohammad Al-Biruni, who serves as the Executive Engineer at the Bagerhat Water Development Board, stated that the district has a total of 338 kilometers of embankments. However, both Rampal and Mongla do not currently have any protective barriers in place. He also mentioned that proposals have been put forward to build an additional 95 kilometers of new embankments.
Suman Fakir, who leads the Bagerhat District Shrimp Farmers Association, cautioned that numerous shrimp ponds (gher) are under threat. He stated, "Should the rainfall persist and tidal levels increase, fish and shrimp populations in areas like Rampal, Mongla, Morelganj, and Sharankhola might get displaced."
Harun-or-Rashid, who is serving as an official at the Mongla Meteorological Office, mentioned that the sea continues to be extremely rough. The Mongla Port is currently under Signal Number 3, with 47 millimeters of rain documented over the past day. Weather predictions suggest that this rainy spell will likely continue for another two to three days.
Rainfall induced by depression and tidal waves inundate 20 villages in Patuakhali.
Residents, especially those in Bagerhat town, voiced worries about persistent waterlogging issues. A disgruntled store owner commented, “As soon as light rain falls, major thoroughfares get inundated.” They further explained, “This recurrent flooding harms our enterprises each time it drizzles, and unfortunately, we lack an adequate sewage network.”
