FIGURE 9.5.4D Overlaid maps of soil classes and land use.

The dry season (June-August), however, could be characterized by only one or two
rainfall events of very short duration and relatively higher intensity.
9.5.1.1.1.9 Hydrodynamic Characteristics
An extensive study including both site and office work was undertaken to under-
stand the hydraulic characteristics. Data analysis mainly focused on flows, salinity,
and bathymetry data. The system was divided into six regions, as shown in
Figure 9.5.6.
The northern part of the system is the moderate-sized lake called Koycegiz Lake.
It is 13 km long, 2 to 6 km wide, and has an average depth of 25 m. It consists of two
basins, as illustrated in Figure 9.5.7. The northern basin has a maximum depth of 28 m
whereas the southern basin has a maximum depth of 32 m. The surface elevation of
Koycegiz Lake is generally a few decimeters higher than the Mediterranean Sea except
in the event of specific weather conditions. Several streams of various sizes at the
surface and groundwater sources at the bottom feed the lake. Strong salinity and
temperature stratification can be observed. The thickness of the epilimnion is about
10-13 m.
Long-term daily water surface elevation data gathered from the State Hydraulic
Works of the Turkish Republic were analyzed. The results of these analyses showed
that seasonal water level variations are 60-100 cm, with a few exceptionally high
values like 150 cm.
