Mexico's Navy is dredging canals in the southeastern state of Tabasco to help reduce flooding caused by the overflow of the Usuamacinta and Grijalva Rivers, Navy officers told Xinhua.

The navy is clearing natural sediments in a canal that goes 15 kilometres (km) from the flooded area to Frontera, a port on Tabasco's coast, Vice-Admiral Juan Ramon Alcala Pigno, the region's commander, told Xinhua.

Alcala said that the plan was to extend the canal to a total length of 2,100 meters, 40 meters wide and 5 meters deep. But he warned that if a hurricane or a strong cold front were to pass through the area such work would have to be cancelled. The navy will use two self-propelling dredges with a capacity of between 500 and 1,000 cubic meters for 60 days.

"If we manage 40 meters in a decent time, we will try to broaden the canal from 40 to 100 meters," Alcala added.

More than 40,000 people have been evacuated from vulnerable areas around the capital, which are at risk due to the opening of floodgates upstream of the state's major rivers.

Last week, Tabasco officials told media that the region's reservoirs have been at dangerous levels because of heavier rainfall during the July-to-August period than at any other time for the last 50 years. Authorities estimate losses at 10 billion pesos (770 million U.S. dollars).
