Wave Clouds by Nile Rivermouth and Lake Bardawil, Egypt – January 19th, 201031.1N 33.1E
The main image focuses on the fan-shaped Nile River Delta, in Egypt along the shores of the Mediterranean Sea. The river and delta appear bright green, in stark contrast to the surrounding yellow Sahara Desert sands.
The close-up focuses on Lake Bardawil, east of the delta, on the north coast of the Sinai Peninsula. Visible over the Mediterranean just north of the lake are rows of wave clouds, so named for their banded, wave-like appearance.
Lake Bardawil itself is a large, very saline lake whose shallow waters (reaching a depth of about 3 metres) are separated from the Mediterranean Sea by a narrow sandbar. It is about 90 kilometers (56 mi) long, and 22 kilometers (14 mi) wide (at its widest). It covers an area of about 700 km2 (270 sq mi).
