Coastal dunes arise from feedbacks between vegetation and sediment supply. Species-specific differences in plant functional morphology affect sand capture dune shape. In this study, we build on research showing a relationship grass species geomorphology the US central Atlantic Coast. This study seeks to determine ways which four co-occurring (Ammophila breviligulata, Panicum amarum, Spartina patens, Uniola paniculata) differ their accretion. We surveyed biogeography, morphology, associated...
Abstract. Dune height is an important predictor of impact during a storm event given that taller dunes have lower likelihood being overtopped than shorter dunes. However, the temporal dominance wave collision regime, wherein volume loss (erosion) from dune occurs through retreat without overtopping, suggests width must also be considered when evaluating vulnerability to erosion. We use XBeach, numerical model simulates hydrodynamic processes, sediment transport, and morphologic change,...
Runup is the wave-driven component of total water level and a critical metric for characterizing exposure to coastal hazards (Sallenger, 2000; Stockdon et al., 2006). The vertical extent wave runup typically parameterized as function offshore characteristics beach slope (e.g., Recent research has considered role nearshore bars in regulating breaking found that depth bar regulates elevation at shoreline Cohn 2014). However, relationship between morphology various hydrodynamic components...
Abstract. Dune height is an important predictor of dune impact during a storm event given that taller dunes have lower likelihood being overtopped. However, the temporal dominance wave collision regime, wherein significant volume loss (erosion) from will occur through retreat without overtopped, suggests width must also be considered when evaluating vulnerability to erosion. We use XBeach, numerical model simulates hydrodynamic processes, sediment transport, and morphologic change storm,...
Coastal dunes are often the first and primary form of defense against destructive surge waves that accompany extreme storm events. Beach grasses known to affect dune height, width, stability, contributing dune’s ability protect hinterland from wave flooding hazards (Hacker et al. 2012). However, interaction feedbacks between development properties beach (e.g., species, density) is not fully understood. In particular, our knowledge ecomorphodynamic processes controlling recovery coastal...
