The interpretation of images enabled the confirmation of generation routes of longshore current and strong rip current, which results were found to have a very similar tendency to those of point measurement at preceding hydraulic model tests, flow direction and flow velocity measured at digital model test, and plane unit at field observation.
The results concerning the maximum longshore current velocity are presented in Table 7.
Waves and longshore currents have also played an important role for shaping the shoreline.
The monthly longshore sediment transport rates estimated based on the monthly observations on breaking wave height, surf zone width and the longshore currents are presented in the Tables 3 to 6.
On the East Coast, barrier islands usually move from north to south because longshore currents transport sand in the same direction.
This draft is affected by sedimentation deposited by longshore currents. Nome is situated on a beach with prevailing winds running perpendicular to the shoreline.
