Evolution of Çolpan barrier and lagoon complex (Lake Van-Turkey): Sedimentological and hydrological approach

Characteristics of barrier sediments as shape, size, provenance, sedimentary structures, and palaeocurrent directions are determined with field investigations. Smooth, flattened, and rounded polygenetic sediments compose the barrier drifted to the shoreline with coastal processes as wave and longshore currents. Çolpan barrier was created a lagoon completely isolated from Lake Van. This wetland constitutes a habitat for some animals and plants with relatively dilute water than sodic Lake Van's. Water level fluctuation is an important element for the constructive and destructive processes for the barrier and lagoon complex.
