The facies are (1) inner-shelf shoreface transition, (2) seaward slope, (3) bar crest, (4) landward slope, and (5) trough. Vertical sequences and lateral transitions seaward of the bar crest suggest that three wedge- shaped units (inner-shelf-shoreface transition, sea- ward-slope bar crest) interdigitate in an offlap-onlap sequence. To landward the trough and landward slope facies interfinger complexly, while the crest facies forms a simple onlap over landward slope facies. Total reworking of sediments within the bar-trough system is expected every 5 to 6 years, and long-term preservation is limited to the inner- shelf-shoreface transition seaward slope, and trough facies.

A survey of the top 0-3 cm at 430 stations in Lake Grevelingen, which was formed by the 1964 and 1971 damming of a former estuary of the Rhine and Meuse rivers, establishes a trend for median grain size with increasing medial values toward the east (due to former ebb and flood current action in the estuary), and shows that after 1971 much fine- grained material was transported toward the deeper gullies.

fractals' of rias coastline; an example of rias coast from Kamaishi to Shizugawa, northeastern Japan. A. Rept Inst. Geosci., Univ. Tsukuba, 10:66-68.

Fractal characteristics along different contours of subaerial rias coastline in Japan are investigated. A crossover point dividing two different fractal ele- ments migrates from 1.5 to 0.25 km as the elevation of the contour rises from 0 to 50 m. Geomorpho- logical explanations for this and other fractal qualities are discussed. Inst. of Geosci., Univ. of Tsukuba, Japan. (fcs)

an example from Sandy Hook, New Jersey. Mar. Geol., 65(1-2):21-31.

Alongshore distribution of mean grain size, beach- face slope, and an index reflecting slope and grain size showed no systematic trend. There was no evidence of a systematic influence of the headland on wave energy. It is suggested that the ubiquitous headland-bay landform arises as a result of a general distance-decay function away from the headland. Distance-decay functions are typically curvilinear and easily fitted by logarithmic or exponential models. Not only wave processes, but other factors such as sediment supply, may be distributed as a distance decay function with respect to the head- land, resulting in a headland-bay configuration.
