摘要：

An attempt to assess ground water resources of a medium size (4775 km2) drainage basin located on the Crystalline Complex in southern Ghana is presented. Mean annual rainfall 1578 mm, total river discharge 1,886,588 064 m3 a-1 surface runoff 1,320,611,645 m3 a-1, base flow 565,976,419 m3 a-1, were determined from 13 meteorological and 1 river gauging stations located within the basin. From these data, the total runoff coefficient was 36%, surface runoff coefficient was 25% and the base flow coefficient was 11%. Then, Permanent Water Reserve, Qt = 5,333.20 x 10(6) m3 and Recoverable Water Reserve, 2,133.28 x 10(6) m3 a-1 for the aquifer of the basement complex aquifer of the basin were calculated from 42 boreholes.
