Over 1,400 kilometers of rivers have been dredged since the beginning of the fiscal year in March to help prevent potential flooding, the managing director of Iran Water Resources Management Company said Sunday.
“In the past, around 350 to 400 kilometers of rivers were dredged a year on average. That has now increased by about four times so far this year,” the Energy Ministry news portal Paven quoted Mohammadreza Haj Rasouliha as saying.
Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.
During the past nine months, rivers in many provinces have been dredged including Khuzestan, Lorestan, Golestan, Kermanshah, West Azarbaijan, Kerman, Khorasan Razavi and Sistan-Baluchestan provinces among others.
