ABSTRACT
Abu Za’baal Lake, circuitous man -made basins, are formed by the
fracture and extract rocks. This study is a pioneer, on the light on physical
properties ofAbu Za’baal Lakes. The Lakes, inland closed basins, receive
their water from the ground and -seepage waters. Recently Abu Za’baal
consists of three Lakes and filling phase Lake. They occupy the area
benveen Latitudes 3(f 16. 6i and 3(f 17. 58\ N & Longitudes 3r 20.90′ and
31° 21. 69’ E. The Lakes waters cover an area of 608.050 xl rfm:l The
water storage in the Lakes is 5234.075 xl03
m3 The highest surface area.
water depth and water storage are in the First Lake. while thei lowest
values are in the Third Lake. The difference in physico- chemical
properties and their correlation coeffiCients in Abu Za’baal Lakes are
obvious. Abu Za’baal basins are brackish waters. The lower -water
conductivity, salinity and density are in the Second Lake. The pH is always
alkaline. The higher Hydrogen ion concentration is in the Third Lake. The
change in bathymetry, ages and separated macophytes from basin to
another causes the change in their characteristics.
