Figure 16. Schematic representation showing a possible mechanism (modified from Flood (1983) for the formation of sedimentary furrows in southeastern Long Island Sound. Secondary helical flow patterns sweep coarse material, such as nucula shells or sand, into linear zones of convergence. These relatively coarse particles are driven by tidal currents and cut furrows into soft, cohesive sediments.
