The floods have caused production losses worth Tk174.28 crore in Rangpur, Gaibandha, Kurigram, Lalmonirhat, and Nilphamari

Flood situation in the Ganges basin has further improved as water levels in most of its rivers saw a receding trend for the second consecutive day on Sunday as a result of the decrease of heavy downpour and onrushing of water from upstream catchment areas.

Meanwhile, normalcy has started returning to flood affected areas as most of the displaced people already returned to their homes following further improvement of flood situation during the past 24 hours till 9am on the same day in the Brahmaputra basin, reports BSS.

At 9am, among the 30 monitored river points in the Ganges basin, water levels of 22 stations have declined, while they went up at five points, and remained stable at three points. Apart from this, the rivers were flowing below the danger level at 25 points and above the danger mark at four points.

In the Brahmaputra basin, the major rivers and tributaries were flowing much below the danger mark at all points on Sunday following further recession in their water levels, BWDB officials said.

Officials in the district administrations said distribution of rice, cash money, baby foods, and animal fodders allocated by the government continues among flood and erosion-hit families in the affected areas of the eight northern districts.

With the floodwater receding, erosion has become a destructive force in several districts, increasing the sufferings of people already devastated by the floods.

Flood situation improves further

In Gaibandha, people who sought shelter at various dams and high places have started to return home as the flood situation continues to improve. 

However, as floodwaters receded, the erosion of Teesta, Brahmaputra, Jamuna, Ghaghat, Karatoa, and Bangali rivers at various points in the district’s Saghata, Phuulchari, Sundarganj, Sadullapur, and Sadar upazilas became severe. 

In the last few days, about 7,500 families have lost their homes in the river and are living a miserable life. Several schools have already sunk into the Jamuna River, and two more are at risk of meeting the same fate.

District Water Development Board (WDB) Executive Engineer Mokhlesur Rahman said the organization has already started working in the affected areas to prevent further erosion. 

In Munshiganj, the flood situation has improved but there were river erosions at several points of the district.

The water levels of both the Padma and Dhaleshwari rivers have decreased. On Sunday morning, the water level at Mawa point was 6.18 meters—8 centimetres above the danger level, and at Vaggyakul point it was 6.41 meters—11 cms above the danger level. The water level of Dhaleshwari River at Rikabibazar point was 4.85 meters which is 33 cms under the danger level.

Munshiganj Deputy Commissioner (DC) Md Moniuzzaman Talukder said: “As the water level is decreasing, we have noticed river erosion at some points of the district.”

In Tangail, the flood situation has improved further as water levels in various rivers continue to recede.

Sirajul Islam, executive engineer of Tangail WDB, said the overall flood situation in the district is improving. But the river erosion will intensify as the water recedes.

As per district WDB sources, water levels of both Dhaleshwari and Bongshai rivers have decreased but are still above the danger mark. Meanwhile, Jhinai, Fatikjani, and Jamuna rivers are now flowing below the danger level.

Many in the area are suffering from waterborne diseases, and at least 16 people including children have drowned in the floodwaters so far, said local residents. 

In Chapainawabganj, the water level of Mahananda River decreased by seven cms in the last 48 hours and it was flowing 1.01 metres below the danger mark. The water of Padma did not rise in the same period, and it was flowing 1.69 metres below the danger line.

Atikur Rahman, sub-divisional engineer of Chapainawabganj WDB, said all the three rivers (Padma, Mahananda, and Punarvaba) in the district are flowing below the danger mark. But erosion may take place at some points of Padma and Mahananda as the water recedes, he added.

In Faridpur, erosion on the banks of Madhumati River has taken a serious turn in Alfadanga upazila as floodwater continues to decrease.

People of 10 villages under four unions of the upazila have been passing their days in anxiety as a 500-meter road, some dwellings, and croplands have already sunk into the river, reports UNB.

Sultan Mahmud, executive magistrate of WDB, said a road, some dwellings, croplands, and a mosque in Tagarband, Gopalpur, Buraich, and Pachuria unions of the upazila have already been washed away due to erosion, while Bazra, Char Azampur, Chapulia, Chardhanair, and Shakipara villages in the upazila are under threat of erosion.

In Madaripur, the flood situation has started improving as the water level of different rivers is falling in its four upazilas.

However, homesteads of low-lying areas of villages adjacent to Padma and Arial Khan rivers remain waterlogged.

District WDB Executive Engineer Partha Pratim Saha said: “As both rivers are causing erosion at places in Shibchar upazila, we are dumping geotextile bags filled with sands to reduce the rate of erosion at some key points.”
