Effects of large macropores on soil evaporation in salt marshes

David Andrew Barry

The occurrence of macropores in salt marsh sediments is a natural and ubiquitous phenomenon. Although they are widely assumed to affect pore-water flow in salt marshes significantly, the mechanisms involved and their extent are not well understood. We cond ...

Modelling of groundwater-vegetation interactions in a tidal marsh

David Andrew Barry

Wetting and drying due to tidal fluctuations affect soil conditions and hence plant growth in tidal marshes. Here, a coupled one-dimensional model was developed to simulate interacting groundwater flow and plant growth in these wetlands. The simulation res ...

Statistical mechanics of wind wave-induced erosion in shallow tidal basins: Inferences from the Venice Lagoon

Andrea Rinaldo

Wind wave-induced erosional effects are among the chief landscape-forming processes in tidal biomorphodynamics. Wave-driven bottom erosion, in fact, controls the equilibrium elevation and dynamics of subtidal and tidal flat surfaces, and the impact of wave ...

Effects of soil stratigraphy on pore-water flow in a creek-marsh system

David Andrew Barry

In coastal marshes, low-permeability mud is often found overlying high permeability sandy deposits. A recently developed 3D creek-marsh model was used to investigate the effects of soil stratigraphy (a mud layer overlying a sandy-loam layer) on pore-water ...

Signatures of sea level changes on tidal geomorphology: Experiments on network incision and retreat

Andrea Rinaldo

How do tidal networks respond to changes in relative mean sea level (RMSL)? The question on whether the morphological features of a tidal landscape retain signatures of past environmental forcings, or are in equilibrium with current ones, is critical to ou ...

The importance of being coupled: Stable states and catastrophic shifts in tidal biomorphodynamics

Andrea Rinaldo

We describe and apply a point model of the joint evolution of tidal landforms and biota which incorporates the dynamics of intertidal vegetation; benthic microbial assemblages; erosional, depositional, and sediment exchange processes; wind-wave dynamics, a ...

Effects of crab burrows on pore water flows in salt marshes

David Andrew Barry

Macro-pores such as crab burrows are found commonly distributed in salt marsh sediments. Their disturbance on the soil structure is likely to influence both pore water flows and solute transport in salt marshes; however, the effects of crab burrows are not ...
