ABSTRACT
The physico-chemical parameters (pH. oxygen,
temperature, electrical conductance, oxidizable
organic matter as well as chemical composition,
some cations and anions were measured in
about 250 water samplesrepres’!nting 10 sites
fn the main channel Of the Aswan High Dalll
Reservoir during the four seasons. 40 sediment
samples as well representing the bottom
sediments at the same water-sampled sites
were analyzed for Ha·, K+, Ca 2+, Mg2+ as
well as Cu, Mo. ln, P and Fe
The study indicated the effect of the
measured. parometers- on. th, deposition of
the estimated eleme~ts. Colloids as well
are .hared in their deposition by adsorption.
