Abstract
During a field experiment designed to measure wind flow and sediment transport over the beach and foredune at Greenwich Dunes, Prince Edward Island National Park, measurements were made over the course of one day, October 10, 2004, during a storm with wind speeds ranging from 4 ms -1 to over 20 ms -1. This paper reports on sediment transport rates measured on the beach in relation to changes in wind speeds, shear velocity, beach moisture content and fetch lengths over the course of the day. Wind speeds were measured with 5 cup anemometers mounted on a mast on the mid-beach, as well as a number of anemometers mounted at 0.3 m across the beach profile. A 2-D sonic anemometer set at 4m height on the mast was used to measure incident wind speed and direction. Sediment transport intensities were measured with saltation probes co-located with the beach anemometers. The instruments were sampled at 1Hz during runs of one or two hours over the course of the day. Sand transport rates were made over 6 runs lasting 15-30 minutes through the course of the day using 5 vertical sand traps spaced over the beach profile.
