The length of Riau coastlines, Indonesia were approximately 900 km long. Hence, there has been difficulty in prioritizing managing various locations of the coastline damages based on a systematic approach. The objectives of this paper are to apply the state of art in the identification of 16 major coastlines vulnerability index in Riau, and to prioritizing which coastlines should be managed in terms of 4 main aspects such as; technical aspect, economic, environmental, and strategic one. The methodology applied in this paper utilized the combination of the Coastal Vulnerability Index (CVI) and social economic approaches using a Likert’s scale of 1 (low) to 5 (very high). This study has recommended a priority in managing the coastlines in Riau was as follow; Pambang Pesisir, Bengkalis and Tanah Merah, Meranti Islands. These coastlines were calculated as the very high level of vulnerability indexes of 75.3 and 74.9 respectively. This study also simulated the use of shoreline protection structure by Genesis software utilizing a revetment construction. The results showed that the construction of revetment structure in Pambang pesisir beach may reduce the shore erosion rate from 10 m/14 year to 0 m /14 year.
