| abstracts | This paper presents analyses of a coastal stability indicator, recently introduced in Poland, that was based on a nearshore sediment volume found between +2 and −6 m ordinates. This purely empirical indicator was developed on the basis of long-term observations (made between 1957 and 2002) of the morphologies of emerged beaches and detailed nearshore seabed monitoring consisting of 969 cross-shore profiles spaced every 500 m that were surveyed between 2004 and 2006 along the entire Polish coast. It was introduced to quantify the requirements for beach nourishment and adopted as the main erosion-control instrument dictated by the Coastal Protection Act of 2003. Extensive seabed monitoring provided data for determining the shoreface sediment volume and led to the conclusion that a mean sediment volume (between 2 m above and 6 m below mean sea level) in excess of 1,500 m3 was a strong indicator of a stable coast. This assumption and the implications of it are discussed. Specifically, simple theoretical considerations pointed to a possible relationship of this indicator with the mean sediment diameter, D50, which was between 0.20 and 0.22 mm, and to a general relationship between D50 and shoreface sediment volumes. |
