Available in PDF, EPUB and Kindle. Book excerpt: Noda (1971, 1972) proposed a two-dimensional, coastal movable-bed, scale-model relationship with four basic scale ratios: (a) horizontal scale, (b) vertical scale, (c) sediment-size ratio, and (d) relative specific weight ratio. The model law was derived by empirically matching the distance from the stillwater level (SWL) intercept to the toe of the foreshore. This study was conducted to investigate the effects of the model sediment-size distribution and particle shape in movable-bed models and, if possible further refine Noda's scale relationship. An experimental evaluation of the scale model relationship was also performed.
