摘      要：Plain reservoirs are shallow, and have low dams and widespread water ***, wind-wave-induced damage to the dam is one of the important factors affecting the safety of the *** improve upon unsatisfactory plain reservoir wave-clipping schemes, a numerical method is proposed to predict and analyze waves in the reservoir in the presence of artificial islands, constructed from dredged *** MIKE21 SW model is applied to a specific plain reservoir for finding the optimal artificial island *** simulated wave height attenuation results are seen to agree well with empirically predicted ***, the validity and reliability of the numerical model are *** islands at suitable locations in the reservoir can attenuate the wave heights by approximately 10%e30%, which justifies the efficacy of the clipping scheme making use of dredging and island construction.
