20. ABSTRACT fContfimia ea revermm sfds ff ne jce ^maty mxd Identify by block number) 



This report summarizes the impact of Hurricane Allen (August 1980) on dune 

 configuration, sand accretion or erosion, and changes in the vegetation on 

 north Padre Island. Four experimental foredunes, the result of grass 

 plantings from 1969 to 1973, and an unplanted control section were monitored 

 in 1975-1977 and also in 1981. The 1981 posthurricane data were compared 

 where possible, with the previous studies. Foredune elevation surveys were 

 completed in March 1981; accompanying vegetation transects were made in July 

 1981. (continued)
