Hydrodynamic study of Chabahar Bay using FVCOM model

Authors

Abstract:

Chabahar Bay is a semi-closed and shallow bay in southeastern of Iran and is strongly affected by the monsoon conditions. The 3D FVCOM model was used to study the hydrodynamic conditions of Chabahar Bay. For this purpose, a horizontal grid with 6290 triangular elements and a vertical grid with 10 sigma layers were created. The model was implemented in baroclinic mode; NCEP data and HYCOM model outputs were used to account for open surface and boundary layer forces. Water level and flow velocity correlations show acceptable agreement with field data. The tidal bay is often semi-daily and mixed and the tidal range is 2.7 m. The flushing time of Chabahar Bay was calculated to be 6.7 days. The modeling results show; The vertically and annual average current velocity is 0.1 m/s and the rotation pattern is often anticyclonic.

A Hydrodynamic Model of Mobile Bay, Alabama

This paper presents a hydrodynamic model of Mobile Bay developed using the Adaptive Hydraulic Modeling system (ADH), the Hydrological Simulation Program FORTRAN (HSPF), and the Mesh Generation and Refinement Tool (MGRT), to simulate water surface elevations in Mobile Bay, Alabama. The computational grid was created using MGRT and NOAA’s coastline and bathymetric data. HSPF provided stream flow ...

Spatial Pattern of Macrobenthos Distribution in Chabahar Bay before Monson

Abstract In the present study, the structure of macrobenthos communities of Chabahar Bay prior to monsoon in 2016 was investigated.  We identified 87 species contain 22 amphipods species, 14 species of other crustaceans, 31 species of molluscs, and 20 polychaets species, where amphipods followed by polychates were dominant taxa. The PERMANOVA test revealed that there is a significant difference...

Parallelization of the Fvcom Coastal Ocean Model

The Finite Volume Coastal Ocean Model (FVCOM) is a publicly available software package for simulation of ocean processes in coastal areas. The unstructured grid approach used in the model is highly advantageous for resolving dynamics in regions with complex shorelines such as estuaries, embayments, and archipelagos. A growing user community and a demand for large-scale, high resolution simulati...
