ABSTRACT
The time-depth variations of the hydrographic parameters
were studied In the Eastern Harbour of Alexandria (EH~),
where the ~ater temperature, salinity and dissolved 0~Ygen
contents were ~eekty determined In the period from Mav 14,
1985 to SeptLrnDer 24, 1986. The eff~ct of Increcci~
domestic sewage qJsntities In the EHA on the hydrographic
conditions was di~cussed. The results reveal thftt the bed
effect of th~t domestic seW8~e on the hydrogr8~~ic cood
tiona of the EHk, especialy on thCl oxygen content. wC1lct.
reached tO~8r the oxy£on depletion state. Thl. ~feht be
due to the organic £ct.hlftiea on ~he· heavy domestle
sewage materials accumUlated on.·~e Harbour’s bott~.
