Over 3,000 houses of 15 villages under Dakop upazila in Khulna district were inundated as an embankment developed two breaches on Sunday and three more early Monday due to pressure of cross current triggered by high tide. Shrimps worth over Tk 50 crore in 600 enclosures and white fishes worth Tk several crore were also washed away, said Rafiqul Islam, president of Dakop upazila unit of Shrimp Cultivators Association. The sudden inundation has cause extensive damage to Boro crops and vegetable. All schools under this union were closed from Monday due to the flooding. Hundreds of marooned people were shifted to different buildings and academic institutions unaffected by the inundation, said Dakop UNO Md Mohosin Ali. Engineer Anwar Hossain of Water Development Board said swelling of Pashur and Shibsha rivers due to high tide is responsible for the embankment collapse.
