“…The FVCOM was widely used to study the hydrodynamic and transport process in aquatic areas such as lakes, estuaries and oceans [11][12][13][14] . It was applied in shallow waters, like Lake Taihu in China to study the surface mixed layer depth [15] , and also Lake El-Manzala in Egypt for salinity distribution and water management [16] .…”

Abstract:In this paper, the hydrodynamic characteristics of water flow in Chaohu Lake are studied by using the finite volume coastal ocean model (FVCOM), which is verified by the observed data. The typical flow field and the 3-D flow structure are obtained for the lake. The flow fields under extreme conditions are analyzed to provide a prospective knowledge of the water exchange and the transport process.The influence of the wind on the flow is determined by the cross spectrum method. The results show that the wind-driven flow dominates most area of the lake. Under prevailing winds in summer and winter, the water flows towards the downwind side at the upper layer while towards the upwind side at the lower layer in most area except that around the Chaohu Sluice. The extreme wind speed is not favorable for the water exchange while the sluice's releasing water accelerates the process. The water velocity in the lake is closely related with the wind speed.

“…The Gulf model was developed using unstructured grid Finite Volume Coastal Ocean Model (FVCOM) (Chen et al 2003). With the merit of an unstructured grid for ideal geometrical fitting Tian and Chen 2006;Xue et al 2009), FVCOM has gained its popularity in research and applications to estuaries and coastal oceans (Weisberg and Zheng 2006;Chen et al 2008;Cowles et al 2008;Zhao et al 2010;Xue et al 2011;Beardsley et al 2013;Chen et al 2014). The horizontal resolution of the model grid varies from ;3 km near the coast to ;5 km in the offshore region of the Gulf and gradually decreases to 10-15 km close to the open boundary (Fig.…”

Because of the scarcity of observational data, existing estimates of the heat and water budgets of the Persian Gulf are rather uncertain. This uncertainty leaves open the fundamental question of whether this water body is a net heat source or a net heat sink to the atmosphere. Previous regional modeling studies either used specified surface fluxes to simulate the hydrodynamics of the Gulf or prescribed SST in simulating the regional atmospheric climate; neither of these two approaches is suitable for addressing the above question or for projecting the future climate in this region. For the first time, a high-resolution, two-way, coupled Gulf-atmosphere regional model (GARM) is developed, forced by solar radiation and constrained by observed lateral boundary conditions, suited for the study of current and future climates of the Persian Gulf. Here, this study demonstrates the unique capability of this model in consistently predicting surface heat and water fluxes and lateral heat and water exchanges with the Arabian Sea, as well as the variability of water temperature and water mass. Although these variables are strongly coupled, only SST has been directly and sufficiently observed. The coupled model succeeds in simulating the water and heat budgets of the Persian Gulf without any artificial flux adjustment, as demonstrated in the close agreement of model simulation with satellite and in situ observations.The coupled regional climate model simulates a net surface heat flux of 13 W m 22 , suggesting a small net heat flux from the atmosphere into the Persian Gulf. The annual evaporation from the Persian Gulf is 1.84 m yr 21 , and the annual influx and outflux of water through the Strait of Hormuz between the Persian Gulf and Arabian Sea are equivalent to Persian Gulf-averaged precipitation and evaporation rates of 33.7 and 32.1 m yr 21 , with a net influx of water equivalent to a Persian Gulf-averaged precipitation rate of 1.6 m yr 21. The average depth of the Persian Gulf water is ;38 m. Hence, it suggests that the mean residency time scale for the entire Persian Gulf is ;14 months.

“…Some of the wave processes that impact the coastal environment are as follows: (i) wave set-up during cyclones, which contributes significantly to storm surge and inundation; for example, when waves were included in the model, Beardsley et al (2013) found that more areas were influenced by flooding in the Massachusetts Bay. (ii) Wave-current interaction increases the bottom friction, thereby increasing the bottom stress.…”

Abstract. The present work describes the interaction between waves and currents utilizing a coupled ADCIRC+SWAN model for the very severe cyclonic storm Hudhud, which made landfall at Visakhapatnam on the east coast of India in October 2014. Model-computed wave and surge heights were validated with measurements near the landfall point. The Holland model reproduced the maximum wind speed of ≈ 54 m s −1 with the minimum pressure of 950 hPa. The modelled maximum surge of 1.2 m matches with the maximum surge of 1.4 m measured off Visakhapatnam. The two-way coupling with SWAN showed that waves contributed ≈ 0.25 m to the total water level during the Hudhud event. At the landfall point near Visakhapatnam, the East India Coastal Current speed increased from 0.5 to 1.8 m s −1 for a short duration (≈ 6 h) with net flow towards the south, and thereafter reversed towards the north. An increase of ≈ 0.2 m in H s was observed with the inclusion of model currents. It was also observed that when waves travelled perpendicular to the coast after crossing the shelf area, with current towards the southwest, wave heights were reduced due to wave-current interaction; however, an increase in wave height was observed on the left side of the track, when waves and currents opposed each other.
