" Geomorphology of the South Shore of Long Island, New York " 

 by N. E. Taney. 



The geologic factors which have influenced the development 

 of the south shore of Long Island to date are treated in 

 broad scope. Interpretation of geologic events are drawn 

 from the works of many authors, and a history of shore line 

 changes and inlet migration is compiled from available 

 USC&GS and Corps of Engineers survey data. Graphic pre- 

 sentation of the shoreline history is included. Littoral 

 transport rates are estimated. All readily available 

 survey data and comparative volumetric changes therefrom 

 are tabulated in appendices.

'Littoral Materials of the South Shore of Long Island, New 

 York " by N. E. Taney. 



Physical characteristics of littoral materials, which 

 are present and have influenced the development of the 

 south shore of Long Island, are treated in broad scope. 

 Statistical parameters of median diameter, sorting and 

 skewness, describing the beach and bottom sediments, are 

 presented for comparable zones of the profile and comparable 

 survey periods at all locations where such data are avail- 

 able. A limited amount of data on such physical properties 

 as mineral composition, roundness and sphericity of grains 

 specific gravity and mass density are also tabulated for 

 the limited areas where they are available. Interrelation 

 of these sedimentary properties and their relationship to 

 geographic location are also investigated.

"The Analysis of Observational Data from Natural Beaches " 

 by W. C. Krumbein. 



Information is presented leading to use of mathematical 

 and statistical approaches for handling large and complex 

 sets of data with use of high-speed computers in analysis 

 of natural beach data. The information is designed in 

 part to set these newer approaches toward natural beach 

 studies in a frame-work that shows the relation between
