The flooding that blocked several roads and streets in Qatar following thunder showers on 26 November is likely caused by ditch channel drainage filled with dune sand, a road construction expert tells MEED.

“Unlike in Europe, ditch channel drainage is not the best solution for the GCC states,” the source tells MEED.

The more suitable solution for the GCC states would be the use of storm water drainage that relies heavily on concrete culverts – both box and pipe – with rip rap protection at inlets and outlets, MEED was told.

It is understood that Oman pioneered the use of storm water drainage among the GCC states.

According to local media, localised flooding occurred in main roads including Al-Waab Street and Al-Bustan Street, with roads in the Industrial Area being worst hit. Side streets in residential areas including Onaiza, Al-Azizya, Al-Maamoura, and Barwa City are also understood to have been flooded.

The flooding in several roads in Qatar occurred despite efforts by the Public Works Ministry (Ashghal) to mobilise a rain preparedness strategy. The plan was launched in October in anticipation of the wasmi season, or the two month-period from November to January where the state expects increased rainfall. The plan included the maintenance of Qatar’s 45,000 manholes and numerous tunnel pumping stations, according to a local media report.

Key retail establishments and malls such as the Villagio Malls and Landmark Malls were also understood to have experienced leaked roofs.

In November 2015, heavy rains caused flooding at Doha’s Hamad International airport and blocked several roads and closed schools and malls.

The 2022 Fifa World Cup will take place between 21 November and 18 December 2022. Qatar will be under heavy pressure to ensure that its road and other infrastructure will be able to withstand rainfall without flooding during this period.

Ashghal has recently invited an interest from contractors for the nationwide maintenance and rehabilitation of its roads and streets.
