Surfzone hydrodynamics as a key determinant of spatial variation in rocky intertidal communities.
Larvae of intertidal species develop at sea and must return to adult habitats to replenish populations. Similarly, nutrients, detritus and plankton provide important subsidies spurring growth and reproduction of macroalgae and filter-feeding invertebrates that form the foundation of intertidal communities. Together, these factors determine the density and intensity of interactions among communi...
متن کاملTransport of larvae and detritus across the surf zone of a steep reflective pocket beach
Larvae of many intertidal species develop offshore and must cross the surf zone to complete their onshore migration to adult habitats. Depending on hydrodynamics, the surf zone may limit this migration, especially on reflective rocky shores. As a logistically tractable analog of a rocky shore environment, we carried out a comprehensive biological and physical study of the hydrodynamics of a ste...
متن کاملNumerical simulations of larval transport into a rip-channeled surf zone
Competent larvae of intertidal invertebrates have to migrate toward shore for settlement; however, their migration through the surf zone is not understood. We investigated larval transport mechanisms at a ripchanneled beach. Because tracking larvae in the surf zone is infeasible, we used a three-dimensional biophysical model to simulate the processes. The coupled model consists of a physical mo...
متن کاملEvaluation of the Cerc Formula Using Large-scale Model Data
Longshore transport experiments were conducted in a large-scale physical model to evaluate predictions of the CERC formula with measured longshore sediment transport rates. It was found that the CERC formula produced reasonable estimates if the coefficient K was calibrated and applied to waves with similar breaker type. The calibrated K values are much smaller than values that are commonly used...
متن کاملThe Vertical Structure of Shallow Water Flow in the Surf Zone and Inner Shelf
1. Theoretical investigations of the vertical structure of mean currents, tidal flows, and low frequency (infragravity) oscillations on the inner shelf and inside the surf zone. This work expands on recent theoretical developments for shear instabilities that follow methodology developed for tidal flows on the continental shelf. Results will be compared with field data examined as part of the s...
