- Abstract
The distribution of precipitation in different fractions (i. e. throughfall, stemflow and interception) is the first interaction between the water cycle and the forest. These fractions have been evaluated over a period of three successive years under the cover of green oak (Quercus ilex L.) in Hamla forest, eastern Algeria using specific collection devices under cover for the throughfall, sealed on the trunks for the stemflow, and installed on bare soil for the precipitation. The results showed that the rate of water coming by throughfall was on average 57.4% of the precipitation. Stemflow represented a small fraction of precipitation (6.7%). The interception was high. It was on average 35.8% of the precipitation. In general, the interannual variability was significant. It is attributed mainly to the importance of the daily precipitation. The relationships between precipitation, stemflow and throughfall at the study site were assessed by linear regressions which revealed strong correlations between different fractions of water and precipitation. R2 varied between 0.74 and 0.99.
