Sediment Transport in Storms
Objective: To investigate nearshore processes related to sediment transport during
storms and the impact of these processes on nearshore bathymetry. The STORM
team uses the unique capability of the Sensor Insertion System (SIS) at the Field
Research Facility (FRF) to capture these processes in energetic wave conditions
(individual wave heights up to 5 m).
The first phase of the STORM experiment was conducted 23 March - 12 April
1997. They measured nearshore processes during the 1-2 April Northeaster, with
Hmo up to 3 m with very oblique wave directions, and the recovery period following
storm with long-period swell. The primary STORM measurements included waves,
currents, sediment concentration, bed elevation, and sediment size (using traps) at
nine cross-shore stations. The measurement times were centered on each high and
low tide during the storm, with nearly continuous SIS operation. Supplementary
measurements included foreshore surveys, larger-scale bathymetry surveys, lead-lining profile,
swash transport, bedforms, video, and dye releases. The effect of the FRF
pier on nearshore processes is also being investigated. The second phase of the
experiment will be in October 1997 during the SandyDuck Experiment.
The STORM team is lead by Don Resio and Carl Miller.
