Anti-flood work starts in blighted Mandra

Anti-flood work starts in blighted Mandra

As autumn showers loom, the Infrastructure Ministry and Attica Regional Authority are scrambling to complete several projects that they hope will prevent the kind of flash floods that killed more than 20 people last November in Mandra, west of Athens.

The key projects concern work to unclog and divert the natural streams of Soures and Aghia Ekaterini that run down the slopes of Mount Patera through the working-class town of Mandra on the coast of West Attica, but have been blocked up by illegal construction, causing last year’s lethal flash floods.

Work there started in mid-August and is expected to take 10 months to complete, according to Attica’s Deputy Regional Governor Christos Karamanos.

Next week, meanwhile, an agreement for repair and expansion work on a stretch of the Athens-Thiva national highway that was destroyed in last year’s flood is expected to be signed and should take 16 months from the start date to complete.

Experts, however, are skeptical.

“These projects were studied on the basis of old hydrological data,” warns Athens University Geology Professor Dimitris Papanikolaou.

“They were based on a maximum level of rainfall of 50 or 60 centimeters, when in the past few years we have been getting 80, 100 and even in extreme cases 200 centimeters.”

Papanikolaou believes that these projects should also be accompanied by work to stem the flow of water nearer the source of the streams.
