Zhang, M.; Sun, Z.; Sun, J.; Suo, A., and Ashraf, M.A., 2018. Evaluation method for effective coastal repair in Moon Bay, Yingkou, China. In: Ashraf, M.A. and Chowdhury, A.J.K. (eds.), Coastal Ecosystem Responses to Human and Climatic Changes throughout Asia.

To evaluate the effect of coastal beach engineering, coastal geomorphic changes before and after repairs were monitored. A comprehensive coast repair index (CCRI), beach repair index (BRI), and tidal flat repair index (TRI) were established to evaluate the effects of coastal reparation. All three indices were calculated and graphed based on GIS. This study's coast (Moon Bay, Yingkou, China) was divided into 12 units to apply evaluation methods for the effect of coastal repair engineering. Results show this evaluation method can effectively determine the overall results of coastal repair engineering in Moon Bay. The CCRI was above 0.70 in middle units 6, 7, 8, and 9, while a range of 0.60–0.699 was calculated for west units 1, 2, 3, and 5. The value dropped below 0.60 in east units 10, 11,12, and 4. The BRI and TRI showed the same trends.
