EVALUATION OF HYDRODYNAMIC CHARACTERISTICS OF THE BOSPORUS REGARDING THE PERFORMANCE OF THE MARINE OUTFALL SYSTEMS

Considering strong interrelations between hydrodynamic features of the Bosphorus and the tube-tunnel crossing which may affect the performan ce of marine outfall systems, the Institute of Marine Science and Tech nology (IMST) conducted a comprehensive meteo-oceanographic data acqui sition campaign to collect information both for the reliable design of marine outfall systems and for the environmental impact assessment (E IA) of the railroad tunnel, on the joint request of the owners of the projects. The main objectives of this paper are to outline the results of the EIA, and also to discuss the newly adopted plan which proposes to divert the sewage collected in the Kadikoy drainage area to Riva, located along the Black Sea Recent evaluations by the authors on the b locking of lower layer flow, and findings presented on the mixing alon g the Bosphorus, have been included as scientific evidences in this di scussion.
