Modelling of groundwater-vegetation interactions in a tidal marsh

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 ...

EXPERIMENTAL VALIDATION OF A CONSTANT SURFACE SHEAR STRESS IN PARTICLE SALTATION LAYERS

Benjamin Andreas Walter

Owens second hypothesis [1] states that the surface shear stress induced by the fluid on the stationary sediment on the ground in a particle saltation layer equals the threshold for particle entrainment. Despite the fact that most numerical models describi ...

Geomorphic signatures of deltaic processes and vegetation: The Ganges-Brahmaputra-Jamuna case study

Andrea Rinaldo

Deltas are complex ecogeomorphic systems where features such as channels and interchannel islands are present over a wide range of spatial scales. A quantitative description of the morphology of deltas is fundamental to address how they react to changes in ...

Tidally driven multiscale pore water flow in a creek-marsh system

David Andrew Barry

Intertidal wetlands are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on three-dimensional, variably satur ...

Tide-induced surface water and groundwater interactions in coastal wetlands

David Andrew Barry

Intertidal wetlands such as salt marshes are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on 3D, variably ...

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 ...

On the tidal prism–channel area relations

Andrea Rinaldo

We verify the broad applicability of tidal prism cross-sectional area relationships, originally proposed to relate the total water volume entering a lagoon during a characteristic tidal cycle (the tidal prism) to the size of its inlet, to arbitrary shelter ...

Effects of wave forcing on a subterranean estuary

David Andrew Barry, Roham Bakhtyar, Clare Robinson

Wave and tide are important forcing factors that typically co-exist in coastal environments. A numerical study was conducted to investigate individual and combined effects of these forces on flow and mixing processes in a near-shore subterranean estuary. A ...

Tidal influence on BTEX biodegradation in sandy coastal aquifers

David Andrew Barry, Alessandro Brovelli, Clare Robinson

A numerical study was conducted to investigate the influence of tides on the fate of terrestrially-derived BTEX discharging through an unconfined aquifer to coastal waters. Previous studies have revealed that tide-induced seawater circulations create an ac ...

Prediction of Longshore Sediment Transport Using Soft Computing Techniques

David Andrew Barry, Roham Bakhtyar

An important task for coastal engineers is to predict the sediment transport rates in coastal regions with correct estimation of this transport rate, it is possible to predict both natural morphological or beach morphology changes and the influence of coas ...
