| Summary: | This circulation of tidal currents in the northern part of the Bali Sea was created using
two main steps, namely a large model simulation and a small model simulation. The first step,
a large model simulation detailing the circulation of tidal currents in the Bali Strait, uses a 2D
barotropic hydrodynamic model that utilizes tidal-generating forces and Gebco bathymetry data
with a 30 second resolution. In this large model simulation, tidal heights are procured which are
then used as data for the small model. The second step, a small model circulation which focuses
on the northern part of the Bali Sea, uses a 2D barotropic hydrodynamic model and utilizes
tidal-generating forces from the large model and BIG (Geospatial Information Agency)
bathymetry data with a 50 meter resolution. This smaller resolution is used to observe the effects
from the cape in the northern Bali Sea.
The tidal simulation is done for 29 days (May 2016) with inputted data in the form of
bathymetry and tidal data at four points with open boundary conditions. The results of the tidal
simulation indicate that tidal currents follow the phase of the tides. During high tides, the tidal
currents move North and during low tides, the currents move South. Meanwhile, for the area
around the Gondol Cape in Northern Bali, an eastward-westward current is observed. |
