|a In the face of a global rise in sea level, understanding the response of the shoreline to changes in sea level is a critical scientific
goal to inform policy makers and managers. A body of scientific information exists that illustrates both the complexity of the
linkages between sea-level rise and shoreline response, and the comparative lack of understanding of these linkages. In spite of the
lack of understanding, many appraisals have been undertaken that employ a concept known as the bBruun RuleQ. This is a simple
two-dimensional model of shoreline response to rising sea level. The model has seen near global application since its original
formulation in 1954. The concept provided an advance in understanding of the coastal system at the time of its first publication. It
has, however, been superseded by numerous subsequent findings and is now invalid.
Several assumptions behind the Bruun Rule are known to be false and nowhere has the Bruun Rule been adequately proven; on
the contrary several studies disprove it in the field. No universally applicable model of shoreline retreat under sea-level rise has yet
been developed. Despite this, the Bruun Rule is in widespread contemporary use at a global scale both as a management tool and as
a scientific concept. The persistence of this concept beyond its original assumption base is attributed to the following factors:
1. Appeal of a simple, easy to use analytical model that is in widespread use.
2. Difficulty of determining the relative validity of dproofsT and ddisproofsT.
3. Ease of application.
4. Positive advocacy by some scientists.
5. Application by other scientists without critical appraisal.
6. The simple numerical expression of the model.
7. Lack of easy alternatives.
The Bruun Rule has no power for predicting shoreline behaviour under rising sea level and should be abandoned. It is a
concept whose time has passed. The belief by policy makers that it offers a prediction of future shoreline position may well have
stifled much-needed research into the coastal response to sea-level rise.
