“…The unstructured 395 grid can be designed to provide a customized variable resolution to both coastline and 396 bathymetry. With the merits of ideal geometric fitting and local refinement of mesh 397 resolution, FVCOM has been used in numerous applications to estuaries, coastal oceans, 398 and the Great Lakes [Yang et al, 2013;Xue et al, 2015;Anderson et al, 2016;Xue et al 399 2017; Khangaonkar et al, 2018, Ye et al, 2018. These characteristics make the model 400 well suited for the study of Sandusky Bay.…”

45Current numerical methods for simulating biophysical processes in aquatic environments 46 are typically constructed in a grid-based Eulerian framework using the advection-47 diffusion equation for physical transport with source and sink terms describing biological 48 processes. Often, the biogeochemical processes and physical (hydrodynamic) processes 49 occur at different time and space scales, and changes in biological processes do not affect 50 the hydrodynamic conditions. Therefore, it is possible to develop an alternative strategy 51 to grid-based approaches for linking hydrodynamic and biogeochemical models that can 52 significantly improve computational efficiency for this type of linked biophysical model. 53In this work, we utilize a new technique which links hydrodynamic effects and biological 54 processes through a property-carrying particle model (PCPM) in a Lagrangian/Eulerian 55 framework. The model is tested in idealized cases and its utility is demonstrated in a 56 practical application to Sandusky Bay. Results show the integration of Lagrangian and 57Eulerian approaches allows for a natural coupling of mass transport (represented by 58 particle movements and random walk) and biological processes in water columns which 59 is described by a nutrient-phytoplankton-zooplankton-detritus (

“…To simplify the total momentum sink rate, the tidal energy dissipation caused by the drag of the turbines' support poles and foundation was not considered. Therefore, the momentum sink approach (with a retarding force in the momentum equation) was adopted in this study for estimating the magnitudes of speed that would be reduced due to tidal energy extraction by the turbines [10,[13][14][15]. The equation can be expressed as [10]:…”

“…Chen et al [9] refined a three-dimensional hydrodynamic model to evaluate the tidal stream energy at Kinmen Island in Taiwan. Yang et al [10] presented a three-dimensional model to study in-stream tidal energy extraction and assess its effects on the hydrodynamics and transport processes in a tidal channel and bay system connected to a coastal ocean. They demonstrated that tidal energy extraction had a greater effect on the flushing time than on the volume flux reduction, which could negatively affect the biogeochemical processes in estuarine and coastal waters.…”

Tidal stream speeds in straits are accelerated because of geographic and bathymetric features. For instance, narrow channels and shallows can cause high tidal stream energy. In this study, water level and tidal current were simulated using a three-dimensional semi-implicit Eulerian-Lagrangian finite-element model to investigate the complex tidal characteristics in the Taiwan Strait and to determine potential locations for harnessing tidal stream energy. The model was driven by nine tidal components (M 2 , S 2 , N 2 , K 2 , K 1 , O 1 , P 1 , Q 1 , and M 4 ) at open boundaries. The modeling results were validated with the measured data, including water level and tidal current. Through the model simulations, we found that the highest tidal currents occurred at the Penghu Channel in the Taiwan Strait. The Penghu Channel is an appropriate location for the deployment of a tidal turbine array because of its deep and flat bathymetry. The impacts of energy extraction on hydrodynamics were assessed by considering the momentum sink approach. The simulated results indicate that only minimal impacts would occur on water level and tidal current in the Taiwan Strait if a turbine array (55 turbines) was installed in the Penghu Channel.

Using multifractals to evaluate oceanographic model skill

et al. 2016

We are in an era of unprecedented data volumes generated from observations and model simulations. This is particularly true from satellite Earth Observations (EO) and global scale oceanographic models. This presents us with an opportunity to evaluate large‐scale oceanographic model outputs using EO data. Previous work on model skill evaluation has led to a plethora of metrics. The paper defines two new model skill evaluation metrics. The metrics are based on the theory of universal multifractals and their purpose is to measure the structural similarity between the model predictions and the EO data. The two metrics have the following advantages over the standard techniques: (a) they are scale‐free and (b) they carry important part of information about how model represents different oceanographic drivers. Those two metrics are then used in the paper to evaluate the performance of the FVCOM model in the shelf seas around the south‐west coast of the UK.
