3. ABSTRACT (Continue on reverse aide H neceaaary and identify by block number) 



The effects of water level changes on shore recession are particularly 

 important in the Great Lakes because annual mean lake levels often rise 

 rapidly for periods of 5 to 10 years and then decline for a similar number of 

 years. To a limited extent, man can anticipate and influence these fluctua- 

 tions. Two methods of predicting the response of a beach to such fluctuations 

 are (a) by measuring rates of shore change at certain locations during and 

 after a recent rise in the water surface elevations, and assuming the next
