English Abstract

The pine forests (Pinus brutia Ten.

) in Zawita sub-watershed were selected for the study during the water-year 2010-2011.

The study area is located about 17 km northeast of Duhok city, Iraq Kurdistan Region.

Two forest stands were pointed , area for each one was 900 m2.

One for the natural pine forest (N) with the age and basal area of 59 year and 19.63 m/ ha.

Respectively , and the other for the artificial pine plantation(A) for the age and basal area of 28 year and 12.2 m/ha.

respectively.

Throughfall(Th), Stemflow(Sf) and Interception loss(Ic) for each forest stands were checked for correlation with gross rainfall(Pg).

The cumulative (Pg) depth of 63 rainfall events for each stands were 652.1mm and 574.95mm.

Mean (Pg) per event was 15.2mm and ranging from 1.95mm to 92.5mm for (N) stand and for (A) stand was 13.4mm and ranging from 1.8mm to 80.8mm respectively.

The storm intensity for both of (N) and (A) stands were ranged from 0.72 to 80.0 mm/hr.

and from 0.60 to 78.4 mm/hr.

respectively.

The accumulative and constituted for both of (Th), (Sf) and(Ic) in (N) and (A) stands were (452.4mm and 443.7mm; 69.4% and 77.2%), (1.59 mm and 3.0 mm; 0.24% and 0.52%) and (198.1 mm- 128.3 mm ; 30.4% and 22.3%) respectively.

Results showed that daily (Th) and (Sf) for (N) and (A) stands were strongly correlated with (Pg), with r(0.99 and o.99) and r(o.92 and o.93) respectively, while (Ic) were moderately correlated with (Pg) with r(0.64 and 0.50) respectively.
