Field and modeling studies of nearshore morphology aims |
|
to understand and predict sediment-transport mechanisms |
|
and their morphologic expression in the coastal marine |
|
environment, with particular emphasis on surf zone |
|
evolution. Principal goals are to effectively and |
|
economically predict bathymetric and sedimentologic |
|
evolution over a variety of time and length scales, to |
|
understand the degree of coupling between the scales, and |
|
to determine the level of uncertainty in predicting |
|
bathymetric evolution. Primary field focus was to study |
|
effects of insufficient sediment supply on nearshore |
|
morphology, such as that common to coastal North |
|
Carolina. ARO and CHL supported development of a LARC- |
|
mounted interferometric sidescan bathymetry system. The |
|
system simultaneously provides high-resolution. swath |
|
bathymetry and sidescan sonar images of the seafloor. |
|
Repeated surveys at the Field Research Facility at Duck, |
|
NC reveal outcropping muddy substrates associated with |
|
anomalous nearshore bar behavior in an otherwise sandy |
|
beach selling. Aerial photographs spanning a twenty-year |
|
period show persistent, recurring differences in bar |
|
morphology between the study site and adjacent areas. |
|
Video imagery also shows that the nearby shoreline has a |
|
much higher variance in erosion and accretion than the |
|
surrounding shoreline. |
