foreshore step. Care should be taken when sampling this zone to cover the 

 main morphologic features of step, trough, and bar crest. Sediment sampling 

 locations based on hydrodynamic zonation appears to provide more information 

 on sediment distributions than sampling on a fixed distance from a baseline 

 (Stauble, Hansen, and Blake 1985). 



61. The main trend of profile response was to erode the above NGVD 

 portion of the beach during the first portion of the study from March 1984 to 

 October 1984. There was a weak seasonal trend of erosion in the spring, fall, 

 and winter months, with accretion in the summer months. A stronger trend was 

 for the occurrence of more storms in the spring and fall of 1984 to cause an 

 alternating erosional trend after storms and a slow accretional trend between 

 storms. The second half of the study period from October 1984 to September 

 1985 had more of a trend for general accretion in both the nearshore and 

 bar/trough area below NGVD and the berm and foreshore area above NGVD. Occa- 

 sional storms caused short periods of erosion, but there was less frequency of 

 storm occurrence during the latter part of the study. 



62. The temporal trend in sediment grain-size distributions was harder 

 to discern than the spatial cross-shore distribution. The use of composite 

 samples helped to remove some of the variability in distributions. By com- 

 positing samples deposited in similar transport dynamic zones, four groups 

 were identified. The dune group had little variation, except for sampling 

 variability of shell material in the vegetated dune area. Since no storm 

 waves reached the dune during the study, the only transport was by wind, with 

 lag deposits of coarser material, resulting in uniform sediment distributions 

 throughout the study. 



63. The beach group was under the influence of wind on the dry beach 

 during fair weather conditions, and during storm conditions the foreshore zone 

 expanded as the wave runup reached higher in the berm area. The daily change 

 in wave conditions, as well as changes in the beach morphology due to swash 

 processes, created the highest variability of any of the groups in the study. 

 Primarily bimodal in character, the beach group showed an increase in the 

 deposition of coarse mode material after high wave events and deposition of 

 more fine mode material during lower wave periods. 



64. The bar/trough group samples were collected in a variety of sub- 

 environments from the step to the trough to the inner bar during the study 

 depending on the shape and location of the bar. The mostly unimodal samples
