Heat Wave to In­ten­sify Wa­ter Woes Across In­dia

The Economic Times - - Companies -

Most parts of the country are in the grip of an ab­nor­mally hot weather, which is ag­gra­vat­ing the wa­ter short­age, and the heat wave is un­likely to abate un­til the on­set of the mon­soon sea­son.

Tem­per­a­ture shot up to 45 de­gree Cel­sius at Tit­la­garh in Odisha, more than 5 de­grees above nor­mal in parts of east­ern In­dia and 3-5 de­grees above nor­mal in many parts of south In­dia, West Ben­gal and Kash­mir. In drought-hit Ma­ha­rash­tra the tem­per­a­ture has gone up 3 de­grees higher than usual.

The wa­ter avail­abil­ity in 91 ma­jor reser­voirs of the country for the week ended April 7 was 24% of the to­tal stor­age ca­pac­ity. This was 69% of the wa­ter avail­able a year ago.

At higher tem­per­a­tures, evap­o­ra­tion rate of wa­ter from var­i­ous wa­ter bod­ies is 6-8 mm per day. Ir­ri­ga­tion de­part­ment of­fi­cials said that mea­sures such as cre­at­ing a chem­i­cal film on the wa­ter sur­face have not proved to be use­ful in the past. “Not only is it a costly af­fair, but it is not ef­fec­tive ei­ther as wind can break the film,” said an of­fi­cial of Ma­ha­rash­tra’s ir­ri­ga­tion de­part­ment.

Ac­cord­ing to PCS Rao, ad­di­tional di­rec­tor gen­eral (me­te­o­rol­ogy) at In­dia Me­te­o­ro­log­i­cal De­part­ment, there will be no respite from the heat wave con­di­tions in most parts of the country in the next two-three days.

“Heat wave con­di­tions will con­tinue in Gangetic West Ben­gal, Odisha, Ray­alseem and Tamil Nadu. Heat wave may de­velop in Marath­wada in next two to three days, while in north In­dia, tem­per­a­tures may rise by 2 de­gree Cel­sius to 4 de­gree Cel­sius in next two to three days,” Rao said.

The spo­radic rain­fall and thun­der­storm ac­tiv­ity that takes place dur­ing this time in penin­su­lar In­dia has been ab­sent this year.
