All flood protection infrastructure, it said, should be reviewed in order to develop an upgrading program. The infrastructure for flood protection will be a combination of creating water retention facilities, facilities to increase water drainage and improving the embankment network.
The experts also highlight the need for a single management body to replace the current fragmentation of responsibilities and propose the establishment of a flood risk monitoring agency. Moreover, it also said there is an urgent need for the installation of an early warning system operating on a 24-hour basis, which will receive, analyze and process flood flow information in real time.
Reference is also made to the problem of man-made interventions in the rivers of Thessaly, which have resulted in the restriction of their beds and floodplains. Rivers and streams are often confined to narrow passages, wedged between embankments to maximize adjacent farmland.
