Karnaphuli water level rises by 12cm annually
CHATTOGRAM, Aug 7: The water level of the river Karnaphuli is increasing more than 12 centimetres annually, says the Hydrography Department of the Chattogram Port authority (CPA), which measures the water level of the river Karnaphuli regularly.
According to a recent survey, the water level of the Karnaphuli was 5.72 metre on July 15 in 2018 while it was 5.87 metres on July 3 in 2019.
In the previous year, the water level of the Karnaphuli had increased 0.15 metre.
Talking to the Daily Observer, Commander Arifur Rahman, Chief Hydrographer of CPA, said the water level of the river had been increasing at a rate of at least 12 centimeters annually on an average.
Following the rise of Karnaphuli water level, one third of the port city, gets submerged regularly during the high tide.
Besides, more areas of the city are being inundated every year due to the rise of water level.
Meanwhile, Chaktai and Khatunganj, the business hub of the country gets inundated twice daily during the high tides.
Mahbubul Alam Preisdent of Chattogram Chamber of Commerce and Industry (CCCI) and the Khatunganj Trade and Industry Association opined that a comprehensive plan is needed to protect the port city from the inundation every year.
He claimed that new areas of the city are being affected every year.
Meteorologists attributed the reason of the rise in the water level to global warming and the siltation of the river Karnaphuli.
It is projected that by 2020, from 500 to 750 million people will be affected by water stress caused by climate change around the world. Low lying coastal regions such as Bangladesh, are vulnerable to sea level rise and the increased occurrence of intense, extreme weather conditions as well as the melting of polar ice. In most countries like Bangladesh, yields from rain-fed agriculture could be reduced by 50 per cent by 2020. As a result of all this, Bangladesh would need to prepare long-term adaptation programmes.
Improving the sustainability and management of forests, wetlands, and rivers is essential to reduce poverty and help Bangladeshis adapt to the effects of climate change.
According to meteorologists, two-thirds of the country has an elevation of five meters or less which leaves the country vulnerable to devastating natural disasters. Long-term impacts from a rise in sea level and global temperature could displace millions of people. Improving the country's resilience to immediate and future climate risks is essential to the continuing development of Bangladesh.
Meanwhile, the siltation of river-bed of the Karnaphuli is continuing alarmingly. Karnaphuli river bed siltation, extending from Sadarghat to Shah Amanat Bridge, has now become a threat to the navigation of the channel of the country's principal seaport.
According to CPA sources, the 2.5-km long navigational channel from Sadarghat to Shah Amanat Bridge has been silted up severely due to Shah Amanat Bridge construction 5.5 km upstream of the main installations of the Port. In view of the rapid siltation of the river Karnaphuli, the CPA has taken the step to conduct capital dredging.
