Scour depths near coastal structures due to the 2011 Tohoku Tsunami

Abstract

Herein, scour depth measurements are compared with theoretical and empirical estimates obtained at four sites in Chiba and Fukushima Prefectures impacted by the 2011 Tohoku Tsunami. At sites where scour was caused by either floodwall overtopping or acceleration of flow around building foundation footings, results of published scour experiments are compared with measured scour depths.
