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.
