Abstract
In June of 2009, a sea trial was carried out around Singapore to study
and monitor physical, biological and chemical oceanographic
parameters. Temperature, salinity and velocities were collected from
multiple vehicles. The extensive data set collected in the Serangoon
Harbour provides an opportunity to study barotropic and baroclinic
circulation in the harbour and to apply data assimilation methods in the
estuarine area. In this study, a three-dimensional, primitive equation
coastal ocean model (FVCOM) with a number of vertical layers is used
to simulate barotropic and baroclinic flows and reconstruct the vertical
velocity structures. The model results are validated with in situ ADCP
observations to assess the realism of the model simulations. EnKF data
assimilation method is successively implemented to assimilate all the
available ADCP data, and thus correct for the model forecast
deficiencies.
