Dynamics of Wind Setdown at Suez and the Eastern Nile Delta
The reef at 29.88° North latitude is not of uniform depth today, but contains several deeper “notches” that were present before the Suez Canal was built . Here we use a single notch to demonstrate how variations in the reef depth may delay the crossing. Point A on the raised portion of the reef is used to compare with the notch (see Figures 5 and 6). The wind blows from the Northwest, as studied by Nof and Paldor  and Voltzinger and Androsov .
