Abstract

Erosion is caused when there is a net loss of sediment in a coastal system, i.e. when the amount of sediment leaving a system is more than the amount of sediment entering that same system. This investigation will focus on vessel-generated waves and their effect on the shorelines of the Jacksonville, Florida Intracoastal Waterways near low tide conditions. The investigation conducted herein examines variations in turbidity and pressure measurements in response to passing vessels at a single site location previously selected in 2016. The primary water/shoreline interaction recorded during this investigation is located below the visible scarp (near low tide conditions). It was concluded that vessel-generated wave height and water level influenced turbidity levels. Turbidity measurements were greater during lower water levels. Vessel passage reduction or no wake zones during low water levels is recommended to reduce the erosion of the intracoastal shorelines into the channel. Future research is recommended to better determine the influence of low tide conditions on turbidity.
