mined from the velocity profile of the Great Isaac well (Eberli and Ginsburg
1987,1989). Only the east side of the Straits of Andros basin was considered for
the simulation. This basin was initially formed as an asymmetric trough approximately 30 km wide with a depth of approximately 370 m (Table Ib).As the program calculates the area of sediments per column across the basin, the basin was
divided into 60 columns of 0.5 km width.
