Dredging Effectiveness Reviewed

An estimated 2,100 kilometers of rivers and canals have been dredged in deluge-prone regions since March 2019 to prevent and reduce floodwater damage.
According to the Energy Ministry’s news portal, before 2018 close to 300 kilometers of rivers were dredged annually on average.
“That has now increased by about seven times so far this year.”
Streams in many provinces have been and are being dredged including Khuzestan, Lorestan, Golestan, Kermanshah, West Azarbaijan, Kerman, Khorasan Razavi, Gilan, Semnan, Markazi, Chaharmahal-Bakhtiari and Sistan-Baluchestan provinces.
Dredging covers a range of activities from the removal of material from the bed and sides of river channels through to the wholesale straightening (canalization) and/or deepening of watercourses.
