In the evaluation of the effects of tsunami-borne debris, it is important to ensure both rationality and efficiency as well as the required safety. Currently, no evaluation procedure has been proposed to include these perspectives. In this study, a comprehensive evaluation procedure that can be applied to both deterministic and probabilistic evaluations of the effects of tsunami-borne debris is proposed. A screening method is also proposed to improve the rationality of the evaluation procedure. The proposed evaluation procedure consists of three phases, each of which incorporates the concept of qualitative and quantitative screening. In each phase, screening is conducted using screening indicators. In this way, it is possible to conduct rational screening of the effects of tsunami-borne debris while ensuring the safety that the target of the evaluation should have. The proposed method contributes to efficient assessment through the reduction of resources required for the assessment.
