The goals of this research, which is part of the USGS Coastal Habitats in Puget Sound Project, are to characterize (1) the geologic framework for deltaic ecosystem structure and (2) the hydrodynamic, sedimentary, and biogeochemical processes that influence ecosystem functions in deltaic and coastal environments. The Skagit Delta and San Juan. Site selection and DNA extraction. Samples were obtained from 16 discrete populations of L. digitata located around the Strangford Narrows of Strangford Lough, Northern Ireland (table 1 and figure 1), in June Although it is recognized that outside the lough wave action as well as currents can influence spore dispersal, in this study we only investigated current action as the greatest Cited by:

To simulate tidal hydrodynamics, this study uses ADCIRC‐2DDI, a code that solves the depth‐integrated shallow water equations for water surface elevations and currents [Luettich et al., ]. The model is a compilation of three previously developed models [Bilskie et al., b].
The unstructured finite element mesh Cited by: While various multi-scale model frameworks have been proposed for modeling the coastal oceans, estuaries, and rivers with a combination of different models, this paper presents a modeling approach for simulating the hydrodynamics in the estuary and river floodplains, which provides a smooth transition between the two regimes using an unstructured-grid, coastal ocean by: The model was therefore forced with realistic water levels, river discharges, winds, coastal buoyancy currents (due to the Mississippi River plume) and surface heat ﬂuxes.
Quantitative metrics were used to evaluate model performance against observations and both spatial and temporal variability in tidal and sub-tidal hydrodynamics were. Coastal developments such as Eastside have the potential to change the local hydrodynamic conditions (i.e. the wave climate, water flows, currents, etc) with knock-on effects to the local sediment transport patterns and the coastal geomorphology (i.e.
the seabed, the beaches, etc). This model can be applied to the studies of the transport and fate of other chemical species. It can be transplanted to other coastal areas as well. The integrated model represents a novel framework in which geochemical processes in coastal environments can be investigated on a truly dynamic basis.

Here we show a coastal model that integrates three existing numerical models into one online-coupled system. The XBeach model simulates storm-induced erosion (Roelvink et al., ). The Delft3D model (Lesser et al., ) is used for long term morphology and the Dune model (Durán et al., ) is used to simulate the aeolian transport.

Estuarine and coastal areas have been intensively studied given their complexity, ecological, and societal value and the importance of their ecosystem services. Estuarine and coastal management must be based on a sound characterization of these areas, which is achievable complementing the comprehensive field measurements with numerical models solutions.

All content should therefore be considered provisional. Christi Bay is a relatively flat, shallow, wind-driven system with an average depth of 3–4 m and a mean tidal range of m. It is completely mixed most of the time, and as a result, depth-averaged models have, historically, been applied for hydrodynamic characterization supporting regulatory decisions on Texas coastal management.

The analysis focuses on the M 2 tidal forcing and the generation of tidal asymmetry in the model domain in terms of the M 4 overtide.

A common type of model used in coastal waters is a coupled coupled hydrodynamic - water quality - ecological model. Such models can be used to study historic conditions in a specific region to try to fully understand the changes that have occured (trends) and the main human factors and natural processes that can explain such changes.
This paper describes the development of a two-dimensional water quality model that solves hydrodynamic equations tied to transport equations with reactions mechanisms inherent in the processes. This enables us to perform an accurate assessment of the pollution in a coastal ecosystem.
