A mathematical wave and weathering model was used to study the formation of subhorizontal platforms in microtidal environments. Backwearing (horizontal erosion) rates by wave erosion were calculated for different tidal levels using basic wave
equations. Downwearing (vertical erosion) rates by weathering and debris removal by waves at the same tidal levels were derived from long-term laboratory experiments and from field data. Model runs suggested that wave erosion was more important in the past
A mathematical model was used to study shore platform development. In addition to mechanical wave erosion, this model considers the effect of a number of other important factors, including platform downwearing by weathering, the abrasive
This paper discusses the use of a mathematical wave erosion model to study the effect of glacially induced sea level changes on the development of shore platforms and erosional continental shelves during the Quaternary. The model used two deep-water
wave sets, which were used to calculate breaker height and depth, and the force of the waves at the waterline, according to the width and bottom roughness of the surf zone and the gradient of the submarine slope. The model also incorporated an erosional
