}}
{{Presenters presentation
|CSDMS meeting abstract presentation=Several models exist to simulate 2D deltaic morphodynamics, but most remain computationally expensive. Here I show that minor simplifications in the governing equations lead to massive increase in computational efficiency. First, the model solves the two-dimensional steady-state shallow water equations while neglecting momentum advection, a term here shown to have a small influence on large-scale and long-term morphodynamics. The resulting momentum equations are linearized with respect to velocity and water level, then solved iteratively. Second, all bed-material transport is represented as suspended load (non-equilibrium) rather than bedload (at-equilibrium). Sediment concentration is assumed to be at steady state, though not necessarily in equilibrium with local resuspension. When discretized numerically, steady-state non-equilibrium transport is mathematically equivalent to at-equilibrium transport subjected to a spatial convolution filter, which explains why the non-equilibrium formulation is orders of magnitude more stable. Third, downslope transport is represented as a bed-elevation diffusion term, with diffusivity proportional to total sediment flux and computed from both upslope and downslope cells. This formulation, equivalent to introducing a transverse sediment flux, is stable when computed with an implicit algorithm and automatically captures bank erosion. The model reproduces large-scale deltaic morphologies that are realistic and comparable to those generated by full hydrodynamic and sediment-transport models, but at a fraction of the computational cost. The model also includes tide and wave hydrodynamics, as well as mud transport and vegetation processes, using which a large range of coastal settings can be reproduced.

{{CSDMS meeting abstract template 2021
|CSDMS meeting abstract=Understanding the response of coastal barrier systems to sea level rise is a crucial societal need. Despite the problem having been studied extensively, major knowledge gaps remain. For example, neither the sedimentary record nor existing numerical models have been conclusive in explaining the formation of barrier islands. Here I present a comprehensive 2D model that seamlessly couples cross-shore and along-shore transport, tidal transport, storm surges, and wind waves, and use it to simulate an idealized passive margin during the last 7,000 years. In the early Holocene, when sea level was rising ~20 mm/yr, shoals and ephemeral barrier islands formed, periodically drowned, and then formed again at a landward location. Shoal emergence was triggered by the disequilibrium of the recently submerged shelf, especially for large waves and mild shelf slopes. About 5000 years ago, as sea level rise slowed down to ~1 mm/yr, barriers stabilized and even prograded seaward. The combination of excess sediment in the nearshore and storm surges allowed barriers to accrete above mean high water. When barriers eventually equilibrated to the new sea level rise rate and started to retreat, their retreat rate was highly variable in space and time due to autogenic processes such as inlet formation and backbarrier channel interception. This variability also included multi-decadal periods of localized progradation. Both lag dynamics and autogenic processes confound the relationship between barrier retreat and sea level rise rate.

{{CSDMS meeting abstract template 2019
|CSDMS meeting abstract=Deltaic, estuarine, and barrier coasts are experiencing unprecedentedly fast rates of morphological changes, which constitute a threat to people, infrastructures, and economies. Predicting these changes in the future could help to develop cost-efficient mitigation and adaptation plans. Here I present recent progresses in simulating large scale and long term coastal evolution using a new morphodynamic-oriented model. Through opportune simplifications the model simulates tides, surges (hurricanes), wind waves, swells, sand/mud/organic sediment, stratigraphy, and vegetation in a numerically-efficient way. The model reproduces the self-organization of barrier islands and the formation of marshes in the backbarrier/estuarine region. The model emphasizes how mud supply is a major driver for the long-term retreat of marshes. The model also simulates how riverine inputs into backbarrier basins – for example through man-made river diversions – can reduce both marsh edge erosion and barrier island retreat.

|CSDMS meeting abstract=The long-term (3000 years) morphodynamics of backbarrier tidal basins is studied using a shallow-water hydrodynamic and wind-wave model (Deltf3D-FLOW-WAVE), modified to include fully-coupled marsh organogenic accretion, biostabilization, drag increase, and wave-induced marsh edge erosion. The latter process is implemented with a novel probabilistic algorithm. In simulations run with only sand, a flood tidal delta forms adjacent to the inlet, but marshes do not establish. In simulations run with only mud, instead, marshes establish at the basin margins and prograde seaward. If enough mud is supplied to the basin from the shelf, marsh progradation counteracts edge erosion. Marsh progradation does not completely fill the basin, but leaves open a few km-wide channels, large enough for waves to resuspend sediment. Starting from a basin (almost) filled with marshes, a drop in the external mud supply or an increase in the rate of relative sea level rise cause the basin to empty out by marsh edge erosion, while the marsh platform, aided by reworking of the sediment released by marsh retreat and mudflat deepening, keeps pace even with fast rates (10 mm/yr) of relative sea level rise. Even if the marsh does not drown, the marsh retreats faster if the rate of sea level rise increases, because more sediment is sequestered to fill the newly created accommodation space and is thus not available for marsh progradation. This study suggests that prediction of marsh erosion requires a basin-scale sediment budget, and that edge erosion, not platform drowning, is likely to dominate marsh loss.

{{Process description model
|Describe processes represented by the model=Sediment advection/diffusion
Sediment settling
Bed erosion
Soil creep
Organic sediment production
Increase in effective settling due to vegetation
Increase in drag due to vegetation
|Describe key physical parameters and equations=-Creep simulated as a linear diffusion process, with vegetation dependent diffusivity
-Suspended sediment concentration variable in time and space throughout the cross section
|Describe length scale and resolution constraints=Spatial resolution 0.1-1 m
Cross section generally 100 m wide
|Describe time scale and resolution constraints=Time resolution ~ 1 minute (it explicitly simulates tides)
|Describe any numerical limitations and issues=Quasi-static tide propagation. Flow neglected when water depth too small.

|One-line model description=A 3-point dynamic model for the morphological evolution of a backbarrier basin composed by marshes and mudflats
|Extended model description=The model simplifies the geometry of a backbarrier tidal basin with 3 variables: marsh depth, mudflat depth, mudflat width. These 3 variables are evolved by sediment redistribution driven by wave processes. Sediment are exchanged with the open ocean, which is an external reservoir. Organic sediments are produced on the marsh platform.
