Flow-biota Interaction and Natural Infrastructure Design
Mangrove forest sustainability hinges upon propagule recruitment and seedling retention. This study evaluates biophysical limitations to mangrove seedling persistence by measuring anchoring force of two mangrove species (Rhizophora mangle and Avicennia germinans). Anchoring force was measured in 362 seedlings via lateral pull-tests administered in mangrove forests of two subtropical estuaries and in laboratory-based experiments. Removal mechanism varied with seedling age: newly-established seedlings failed due to root pull-out while seedlings older than 3 months failed by root breakage. Anchoring force of R. mangle seedlings was consistently and significantly greater than A. germinans (GLM: p = 0.002), however force to …

Predicting Boat Wake Bank Erosion Risk
Wave energy from recreational boat wakes is associated with erosion and degradation of shoreline ecotones. However, wake effects are often assumed to be negligible when boating lanes are located far from shore. In this study, field experiments were conducted to characterize hydrodynamics of recreational boat wakes at the shoreline of a shallow estuary as offshore sailing-line distance varied from 50 to 200m. Results indicate that wake events were considerably more energetic than ambient conditions, with an average 20% increase in wave height, 190% increase in near-bed orbital velocity, and 110% increase in wave-induced shear stress. Wake events generated farther from …
