Despite the increasing evidence of drastic and profound changes in many ecosystems, often referred to as regime shifts, we have little ability to understand the processes that provide insurance against such change (resilience). Modelling studies have suggested that increased variance may foreshadow a regime shift, but this requires long-term data and(More)
We explore the role of biophysical feedbacks occurring at the patch scale (spatial scale of tens of meters) that influence bivalve physiological condition and affect patch stability by developing a numerical model for the pinnid bivalve, Atrina zelandica, in cohesive sediments. Simulated feedbacks involve bivalve density, flow conditions (assumed to be(More)
The relationships between functional linkages within communities and community dynamics are fundamental to biodiversity-stability relationships. By teasing apart the hidden layers within artificial neural networks (ANNs), we developed webs defining how functional groups influence each other's temporal dynamics. ANNs were based on 15 years of bimonthly(More)
Nearshore sandbars, ridges of sand fringing coasts in water depths less than 10 m, often show alongshore variability, known as rips and crescentic sandbars. Using a data set collected at the Gold Coast (Australia) we analyze the sequential development of alongshore variability in a double sandbar system using continuous wavelet and cross-wavelet transforms.(More)
[1] Predicting the development of rip channel systems on beaches is relevant for beach safety, nearshore mixing and dispersion, and has been puzzling researchers for decades. Field observations and computer simulations have focused on predicting the spacing and growth time of rip channels as a function of wave characteristics. A satisfactory predictor of(More)
An ecomorphodynamic model was developed to study how Avicennia marina mangroves influence channel network evolution in sandy tidal embayments. The model accounts for the effects of mangrove trees on tidal flow patterns and sediment dynamics. Mangrove growth is in turn controlled by hydrodynamic conditions. The presence of mangroves was found to enhance the(More)
We develop a consolidation module and merge it into a morphodynamic model to assess the role of consolidation on estuarine morphodynamics. We test the model using two settings: point models without hydrodynamic forcing to validate against two benchmark experimental datasets; and a profile model to simulate a mudflat restoration. The modelled self-weight(More)
