Severe flood likely in north, northeastern parts of country

DHAKA, Aug 12, 2017 (BSS) - Country's northern and northeastern regions may witness severe floods, if the current rising trend of the major rivers continues for the next few days.

"Low-lying areas of northern and northeastern parts of the country may be flooded as the Brahmaputra-Jamuna, Ganges-Padma and Surma-Kushiyara are in the rising trend due to heavy rainfall " Md Sazzad Hossain, executive engineer of Flood Forecasting and warning Centre (FFWC), told BSS today.

"The rising trend of the major rivers may continue for the next three to four days as two Indian states -- Assam and Arunachal -- are also experiencing heavy rainfall, meaning northern and northeastern regions of Bangladesh may be inundated by severe flood," he added.

Low-lying areas of the country are normally affected by floodwater during the months of July and August, Sazzad said adding, "We are forecasting that flood may hit the country this month as monsoon is very active over Bangladesh."

As result of active monsoon, rainfall above 100mm was recorded at nine stations on August 11(Friday) while rainfall at 15 stations above the figure was recorded today (Saturday), he added.

The axis of monsoon trough runs through Punjab, Hariyana, Uttar Pradesh, Bihar, West Bengal to Assam across the northern part of Bangladesh. One of its associated troughs extends up to North Bay.

Monsoon is currently active over Bangladesh and moderate over North Bay, a weather bulletin of BMD said today.

According to long-range weather outlook of BMD, Bangladesh experienced more rainfall than the normal level in July and more rainfall than normal may occur in the current month too.

"The most rainfall takes place in the country in July and August months of the rainy season," an official of Met Office told the news agency.

"The country has been witnessing a powerful monsoon since June 12... Under the influence of this monsoon, heavy rainfalls are occurring in different parts of the country," he added.

Centre for Environmental and Geographic Information Services (CEGIS), a leading expert agency on water resources, recently revealed a report fearing three major rivers to grasp over 3,222 hectares of land by the end of the current 2017.

"The three major rivers (the Jamuna, the Ganges and the Padma) in total may cause erosion of 3,222 hectares of land (in 2017)," the report added.

Meanwhile, Water levels at 81 river stations monitored by the Flood Forecasting and Warning Centre (FFWC) have marked increase while 6 stations recorded fall.

Among the 90 monitored water level stations, 17 river stations were recorded flowing above the danger level, a bulletin issued by the FFWC said here today.

The Dharla at Kurigram, the Teesta at Dalia, the Jamuneswari, the Jamuna at Bahadurabad and the Sirajganj, the Tangon, Surma at Kanaighat and Sunamganj, the Kushiyara at Sheola, the Sarigowain at Sarighat, the Manu at Manu Rly Br, the Khowai at Ballah, the Dhalai at Kamalganj, the Bhugai at Nakuagaon, the Someswari at Durgapur and the Kangsha at Jariajanjail are flowing above danger level 32cm, 25cm, 6cm, 4cm, 10cm, 65cm, 78cm, 70cm, 12cm, 49cm, 7cm, 135cm, 195cm, 13cm, 236cm, 35 and 105cm respectively.
