Researchers have developed a novel statistical model for prediction of floods and its duration. It also accurately determines the timescale of flooding. “It is possible to predict the duration of floods by coupling atmospheric dynamics and land surface conditions in the watershed,” said study researcher Nasser Najibi from the City College of New York.

For the study published in the journal Nature Research, researchers analysed data from the Missouri river basin from the last 50 years to develop the Bayesian network statistical model.

The research team found that long duration floods first require high flow conditions in rivers created by recurrent high-intensity rainfall events, which is then followed by a large stable long-lived low-pressure system — a storm cell. These conditions may then result in large-scale devastating floods.

In shorter duration, however, this land-atmospheric coupling is negligible thus explaining why not all storms result in widespread flooding.

The researchers said that with the help of this statistical model, potential risk imposed by longer duration floods on critical infrastructure systems such as flood control dams, bridges and power plants can be mitigated. It is also possible to predict how long the duration of flooding and inundation will be, they said.

Onam celebrations in Kerala will be a low key affair as the state is recovering from devastating floods, the state Cabinet decided at its weekly meeting here on Wednesday.

Heavy rains have battered several districts of the state since the past fortnight leaving 125 people dead and destroying property worth crores. Over 6,000 people are still staying in 86 relief camps set up in the state.

Last year, the state government was forced to cancel Onam celebrations after the state witnessed similar floods and devastation.

Onam is the harvest festival of the state. It is primarily celebrated for three days, but the festivities continue for more than a week with educational institutions closed and the state holding cultural programmes in all the 14 district headquarters. This year however, the gala may be subdued.

The state government has announced distribution of Rs 10,000 relief payment to all the flood-affected families before September 7. The concerned secretaries and the village officials have been asked to distribute the compensation amount to the victims. (IANS)
