Açıklama : Manavgat River, where the average water depth is around 3.5 m and the width is around 50 m., flows into the Mediterranean Sea near Manavgat Town at 50 km west of Antalya city near Southern coasts of Turkey. The river is heavily used for navigation by small recreational boats and local fishing boats between Manavgat town and the Mediterranean Sea. The river mouth has been unstable because of strong longshore sediment transport and high river flood. Shoaling and shifting of river mouth has been preventing continuous navigation of boats and yachts through the entrance. To stabilize the river mouth some alternative structures were planned to design. Among the alternative designs, jetty type structure is chosen as the protection structure. A continuous shoreline and bathymetry measurement program for monitoring of shoreline changes near the Manavgat River mouth has been performed before and during the construction of the jetties. Also the shoreline changes with and without protection structure was studied by using one line model for shoreline evolution. The construction of steel pile wall jetties at the entrance with 50 m spacing and each approximately 250 m in length with 2 m elevation above water level is still going on. Monitoring of sediment transport processes before and during the construction of coastal structures as in the case of Manavgat River mouth jetties provided a valuable and dependable data to check the reliability of the models used in engineering applications.
