44 rivers of the northern region dying
Farakka Barrage built by India in the upper part of the river Padma followed by the unilateral withdrawal of water through it has left its impact on the rivers flowing across the northern region. About 44 rivers are on the point of dying. A time will come when the rivers would have no existence, experts opine. (The Independent )
According to the experts, the unilateral withdrawal of water from the river Padma has slowed down the flows of the rivers that are fed by it. The rivers with little water from the upper part of the Padma have lost their flow in the dry season.
The rivers though are in spate in the rainy season become lean in their flows in the dry season. Absence of current helps deposit sands and silts on the river beds which are gradually being filled in. Waters in the rainy season overflowing the banks enter into the villages playing havoc with crops of people beside the rivers banks.
People of the northern region are not getting benefits from the meetings that are held every year regarding the due share of water from the Farakka Barrage. With the beginning of dry season the turbulent Padma turns into sandy chars miles after miles and the other rivers fed by the Padma are losing navigability.
Besides the 44 rivers of the northern region, 95 rivers across the country are on the way of losing existence. The list of the rivers that have already died includes the Bhulli of Panchagarh, Choto Chepa, Aman-Damon, Lona, Lachhi of Thakurgaon, Nalshisa, Kula, Gareswari, Ichamati, Mila, Patherghata, Nort, Belan, Tulsiganga, Choto Jamuna, Chiri, Tetulia of Dinajpur, Khorkhoria, Kharubaj, Ghirnai, Chara, Bullai, Auriakhuna of Nilphamari, Naleya, Alaikumari, Mora Teesta of Rangpur, Shib, Musa Khana of Naogaon, Ichamati, Ganglai, Rawnai, Gomani, Boral, Loyar, Chiknai, Sutikhali Khageswari, Hursagar, Nagar of Bogra and Jinjiram of Kurigram districts.
The river research survey terms them seasonal rivers. The rivers which have been silted up contain no water in the dry season. Local people grow different crops on the rivers beds.
The list of the rivers that are on the point of dying includes Chatnai, Pakuraj, Mohanda upper, Tirnoi, Ramchandi, Khorka, Kurum, Gobra, Petki, Gharomara, Korotua, Berang, Bhersa, Tangan, Talma, Dahuk, Chowyai of Panchgarh, Kulik of Thakurgaon, Chepa, Kankra of Dinajur, Chikly, Manash, Dhaijan, Burikhora, Naotara, Dhum, Buri Tilka of Nilphamari, Ghaghot, Akhira of Rangpur, Fulkumar of Kurigram and Boral upper of Rajshahi districts.
An investigation reveals that these rivers which contain little water in the dry season experience no impacts of ebb and tide. The rivers after being silted up would lose their existence in future. This would bring in disaster on the ecological balance.
A survey conducted by Statistics Bureau reveals that the number of rivers across the country is 710.Recently, Hydrological Survey under Water Development Board has published a report mentioning the length, width and depth of the rivers.
The biggest river in length, width and depth is the Meghna. The length of the river is 330-km. Its width near Bhairab is 1.50-km and depth is 27-meter.
The smallest river in the country is Gorra at Tetulia in Panchagarh district. The length of the river is 4-km and its depth is 15-meter. The depth of the river after being silted up has stood to 30-centimeter.The report reveals that the length of the river Padma is 115-km. The width of the river near Mawa is 5-km and 711 meter. Its depth is 18.80 meter.
In the dry season its depth stands at 7-meter. The river Brahmaputra is 60-km long, 10,425-meter wide and 20-meter deep. The river Jamuna is 90-km long, 1200 -meter wide and 12-meter deep.
According to a source in Hydrological Survey Research Centre, the centre selected 90 to 95 rivers for the examination of matters relating to the deposition of silts. These rivers have been divided into five groups.
The rivers-Ganga, Padma, Jamuna and Meghan belong to the first group. Cross section (erosion and silt survey) is conducted in the rivers in the dry season every year. The second group includes 12 rivers where cross section is conducted every two alternate years. The third group includes 19 rivers where cross section is conducted once after three years.
The fourth group includes 20 rivers where cross section is conducted once after four years. The fifth group include 40 rivers where cross section is conducted once after five years.
