Abstract
The objective of this work is the evaluation of precipitation, throughfall, stemflow and
interception. These water fraction were evaluated for a period of six months under the cover of
Quercus ilex in the oak grove of ghomrass in the Aures using containers Rcovery of different types of
water .These containers were placed under cover for dripping sealed on the trunks for flow and
installed on bare soil for precipitation .The result show that the rate of incoming and throughfall water
is on average between 52.66% and 76.3% of incidental precipitation . on average , the stemflow
reprecents only a small fraction 11.67 % of the total the total incidental precipitation . As for
interception is important .It is larhely dependent on the amount of incidental daily rainfall. The
relation ships precipitation , throughfall, stemflow , and interception at the stdy site were assessed by
linear regressions that showed strong positive correlation between precipitation and the two dripping
parametre and the runoff on the other side negative correlation between the between the precipitation
and interception regression have led to equations which can be used as models of prevision
interception .
