The Kifissos river (catchment area: 430km2) is the main recipient of the Athens (4,000,000 total population) basin stormwater discharges. The river, from Kokkinos Mylos up to the sea, about 16km, has been partially trained in the past for discharges of 700, 900, 1100, and 1400m3/s and return period of 1:50 years. These discharges in the Saronicos Gulf were considered low for current conditions and existing river
training was being re-examined for
flood regulation of the upstream (mountainous) part of the river catchment area.
The main scope of the project is:
• the construction of 15 small dams (including the dams : Kifissos 3A , h=29m, Kifissos 4, h=20m, Kifissos 6, h=18m, Kifissos 7, h=18.5m) and embankments in the high river catchment area in order to protect the
downstream areas of Athens along the
trace of the river until the outfall in the
Saronicos Gulf.
• intervention in order to avoid contamination from urban and industrial sewage in the river.
• establishment of institutional unit for the river basin management (participation member will be the Ministry of Environment and Public Works, the municipalities along the river and private firms).
