Abstract

Navigational activities in Turkish coastal areas have been increased and the problem of
dredged material has emerged as an environmental issue of national importance. The
project entitled “Dredging Applications and Environmental Management of Dredged
Material in Turkey: DIPTAR” started in 2014 October, was a first step in the direction of
sustainable dredge material management based on the scientific facts. The aim of the
project was to provide the scientific basis to the Ministry of Environment and Urbanization in the preparation of the “National Dredged Material Management Regulation” considering the international Conventions/Protocols. Data and quantitative information required for this process to move forward smoothly was obtained from the scientific publications and technical reports and new monitoring and characterization (sediment toxicity) studies were also performed at the coastal areas near potential dredge locations. The existing and new data were evaluated to determine the criteria for the disposal/dumping of the dredge material. The suitable sites, for dumping in the sea and disposal over land were identified using tools and applications like three-dimensional hydrodynamic models with sediment transport (STFATE) and geographical information systems (GIS). In addition, potential impacts created by dumping were assessed and the monitoring strategies for the dumping regions were established. An ecosystem based management procedure (decision tree) was formed and tested in the pilot regions with different marine activities. Beneficial usage alternatives of the dredged materials collected from pilot sites were suggested. Stakeholder meetings were performed in key decisions such as identification of the dumping/disposal areas.
