Teesta, Dharla cross danger mark in Brahmaputra basin

RANGPUR, Sept 24, 2020 (BSS) – The Teesta and Dharla crossed the danger mark (DM) as major rivers marked sharp rise following onrush of huge hilly water amid heavy monsoon rains in the Brahmaputra basin during the last 24 hours.

“With sharp rise in water levels, the Teesta was flowing 27cm above the DM at Dalia in Nilphamari and Dharla by 15cm at Kurigram at 9am today,” said Chief Engineer for Rangpur Zone of Bangladesh Water Development Board (BWDB) Jyoti Prosad Ghosh.

The Dharla, Teesta, Brahmaputra and Jamuna might continue to rise further during the next 48 hours to cause a flood-like situation in the basin.

“We are closely monitoring the situation and ready to take immediate steps to save flood control structures on an emergency basis anywhere in the zone,” Ghosh added.

According to a bulletin of the Flood Forecasting and Warning Center (FFWC) of BWDB, the Brahmaputra-Jamuna river systems might continue to rise during the next 24 hours.

Quoting the numerical weather model of Bangladesh Meteorological Department and India Meteorological Department, FFWC said there is a chance of moderate to heavy rainfall in the country’s northern and northeastern regions and adjacent Assam, Meghalaya and Darjeeling areas of India in the next 48 hours.

As a result, major rivers of the country’s northern and northeastern regions might continue to rise and the Dharla and Teesta are likely to remain above the DM in the next 48 hours.

“The recorded rainfalls during the last 24 hours ending at 9am today were 180mm at Jalpaiguri, 274mm at Cherrapunji, 137mm at Jalpaiguri, 91mm at Pasighat and 78mm at Shillong points in northwestern Indian states,” the FFWC bulletin said.

Meanwhile, some low-lying char areas of Nilphamari, Lalmonirhat and Kurigram districts went under floodwaters as the Teesta and Dharla again crossed their respective DM today.

The BWDB officials said water levels of the Dharla sharply rose by 68cm at Kurigram and Teesta by 45cm at Dalia during the last 24 hours and were flowing above their respective DM at these points at 9am today.

Water levels of the Brahmaputra rose by 27cm at Noonkhawa and 14cm at Chilmari points during the period and were flowing below the DM by 75cm and 38cm at these points respectively at 9am today.
