remain constant. If sediments are lost from a shore zone and the shore pro- 

 file retreats landward while its shape remains constant, then a parallelogram 

 can be used to qualitatively and quantitatively describe the change that has 

 occurred on the shore (Bruun 1962; Coastal Engineering Research Center 1973, 

 p. 4-122; Dubois 1977). Most of the shore models in this paper are con- 

 structed from parallelograms and represent a first approximation of the 

 possible behavior of shore profiles in response to rising water levels.

 and Rising Sea-Level: An Opinion," Shore and Beach . Vol 50, pp 30-32. 



Most sandy shorelines around the world are eroding, and one cause of 

 this erosion may be attributed to a relative rise of sea-level. For a shore 

 profile at equilibrium with wave and current processes, Bruun postulated that 

 a rise of sea- level can cause sediments to be eroded from the beach and 

 deposited on the shore bottom so that the bottom can be elevated in direct 

 proportion to the rise of water level; the volume of sediments eroded from the 

 beach is equal to the volume of sediments deposited on the shore bottom. 

 Field and laboratory data have been presented in support of Bruun' s Rule. In 

 recent years, several writers have used or noted Bruun' s Rule in their 

 research. 



The purpose of this paper is to suggest how a rise of water level and 

 wave conditions can be linked to cause beach erosion and nearshore deposition, 

 and to suggest that a rise of sea- level may have an influence on the texture 

 of shore sediments. (Introduction).

The U. S. Atlantic coast water-level climate, developed for the Wave 

 Information Study (WIS) , is comprised of the following products at each of 20 

 locations along the coast. 



a. Trends and variability in mean sea-level. 



b. Magnitudes of the expected water-level climate via 

 estimated probability density and cumulative distribution 

 functions for astronomical tide, storm surge, and total 

 water level. 



c. Duration statistics for both storm surge and water level. 



d. Extremal storm surge information as a result of 

 extratropical storms. 



The nature of the water-level data, the analysis procedures used, and the 

 interpretation of the results are included. (Author) .
