RFP
The analysis included interconnected rural and urban catchments, covering a total area of 9km2. The hydraulic design process included 1D non-uniform flow modeling of three main watercourses, namely the Signal Mountain cutoff drain, the Pouce stream, the Ruisseau des Creoles stream and their feeding drains, corresponding to a total length of 6.3km, including the evaluation of the hydraulic performance of five supercritical flow junctions, sixteen bridges and two covered sections, of around 0.8km. Moreover, it included the proposal of appropriate engineering works to alleviate flooding problems at Place d' Armes and the investigation of potential flood peak attenuation measures at the upstream (rural and semi-urban) parts of the catchments. Among the proposed solutions was the reconstruction of insufficient bridges and culverts, the increase of the hydraulic capacity of the streams, the construction of a flood detention pond and the design of new drainage works in specific areas.

Evros River flows at the eastern Balkan peninsula and its basin covers a total area of 53,000km2, spread between Bulgaria (35,085km² - 66.2% of the total area), Turkey (14,575km² - 27.5%) and Greece (3,340 km2 - 6.3%). The total river flow length is 528km, of which 310km are within Bulgarian territories while the remaining 218km define the borderline of the three countries. It is the second largest river of the Balkans, after Danube, and transports a significant sediment yield, creating an estuary of high environmental value at the Aegean Sea. The Greek part of the basin has around 1.5% of the country's population and is characterized by mostly agricultural and livestock activities.The study aims at identifying future flood risks, based on historic information and detailed hydrologic and hydraulic analyses, in order to propose administrative measures and civil protection actions that will allow for reducing the impact of flooding events in the future.
