Topic of the practice
Good Practice Information
Objective: the effective management and treatment of the waters of river Evros, so as to prevent and mitigate the impacts of floods.
a) Installation of prevention-monitoring systems (installation of a network of automatic stations (censors) for remote monitoring of the river water level)
b) Executing construction works and building engineering structures (e.g. dams, reservoirs, mounds, ditches in dependence with the changing needs of the area (land use, floods frequency etc.) Warning system provides the authorities with statistical data and data in real time. More precious time for reaction is available in emergency cases. Effective monitoring and management of hazard is facilitated through the data recording and processing.
Both types of intervention require: accurate system of collecting, monitoring and processing data, experienced staff, well organized CP services, efficient coordination of administrative services and availability of financial resources.
Engineering works constitute expensive interventions. Engineering interventions are costly investments. In addition they need to be regularly maintained and adapted. Therefore they should constitute part of an integrated flood management system, where land uses, population needs, availability of resources, flood occurrences etc. should all be considered and on the basis of a cost benefit approach decided.
However, in the long run, appropriate utilization of accurate data to developing infrastructure is more cost effective compared to ineffective planning, failure of construction works and damages by floods.
Evidence of success
Significant improvement in terms of warning on the possibility of a river flood, providing time to authorities and local population to prepare and take measures to tackle floods
Appropriate works and engineering structures have been proven very effective to hold the waters in flood occurrence.
