This study evaluates the influence of coastal structures on coastal morphology near Hsin-Chu fishery harbor in the northwest of Taiwan. As a result, the downdrift side has undergone local erosion due to the longshore sediment was impounded at updrift breakwaters resulting the enhancement of coastal flood risks as well as deterioration of the biological environment. Process and trend analyses were used to assess the effects the coastal exploitation made on the coastal morphology. Environmentally-friendly remedial measure, beach nourishment is proposed. The sediment source supply and the location of beach nourishment were also suggested for achieving the goal of sustainable use in the area.
