Coastal districts’ low-laying areas are being flooded continuously by tidal surge, leaving lakhs of people marooned while flood situation deteriorated in the central parts of the country.
The high tidal surge coupled with moderate to heavy rain collapsed dams and embankments destroying houses, damaging crops fields and washing away shrimp farms and fish ponds in the low-laying areas of the coastal districts of Khulna, Satkhira, Chattogram, Noakhali, Laxmipur, Feni, Chandpur, Borguna, Patuakhali, Barisal, Bhola, Pirozpur, Jhalokathi, Bagerhat and offshore islands.
On the other hand, flood situation has deteriorated in the most central districts Faridpur, Rajbari, Mankiganj, Shariatpur, Munshiganj and Madaripur as the water levels in many of the rivers in the Ganges basin continued showing a rising trend again on Sunday in wake of onrushing of floodwater from upstream hilly catchment areas after a steady condition for the last couple of previous days.
Contacted Arifuzzaman Bhuiyan, executive engineer of Flood Forecasting and Warning Centre (FFWC) on Sunday said due to effect of waning moon and moderate to heavy rain fall the coastal districts witnessed the high tide.
“But as the waning moon went away, the effect of tidal has also been reduced. We can predict that the situation will become normal immediately. Besides, the country’s central parts also experienced the deluge due to the effect of moderate rain coupled with on rush of hilly waters from the upstream and tidal surge,” he told the Bangladesh Post on Sunday.
