ASL_CLPnonlinear: No significant reflection was found in the first
10 days. When the plume reaches the OB, the reflection
causes the current flow along the OB. The interior
solution seems to be influenced little from the
OB in a time scale of 50 days. This is consistent
with Chapman (1985) finding.
GWInonlinear: Velocity
and salinity look good, but the sea level in the
entire domain significantly decayed with time. At
50th day, the sea level dropped more than 0.5 m.
This boundary condition is not recommended for freshwater
discharge cases.
BKInonlinear: The
sea level variation is the same as ASLCLP, and
velocity was similar to GWI and better than ASLCLP.
The salinity is similar to ASLCLP and GWI.
ORInonlinear: Velocity
and salinity are similar to BKI, but the sea level
decays with time. However, the decay rate was much
smaller than GWI.
In this simple case, no significant differences
were found for choices of linear and nonlinear approaches
for the calculation of the velocity at the open
boundary cell. However, we do find a significant
difference in the estuarine application when an
open boundary was specified in the area with the
intertidal zone.
