Figure (7-3): Water level oscillations in Edko Lake induced by tidal forcing at two
Stations (Sta. No. 140, 152).
A comparison between the water level oscillations at the sea boundary and at the stations in the lake is
shown in Figure (7-4) (i.e., Sta. No. 140, 159). This verifies that the water levels at the downstream
part of the exit channel to the sea are mainly affected by the tidal level variations.

the Lake (Sta. No. 140).
The 1D-2D model revealed the dynamics of the drainage water discharges from the main drains, and
the coupling of the sea water intrusion into the lake and water level variations. However, model could
not provide a clear definition of the direction of the flow velocities.
7.4. DETAILED 2D HYDRODYNAMIC SHALLOW LAKE MODEL
The detailed 2D hydrodynamic model of the shallow lake was developed using the Delft3D
Mathematical model package. The model was developed for a further and more detailed study of the
