Abstract
Bu çalışmada, Türkiye'nin kuzey batısında Zonguldak'ta (41ºK-31ºD) yer alan ve su toplama alanı yaklaşık 12 km2 olan ormanlık bir dağ akarsuyu (Harmankaya) dalma havuzlarıyla ilişkili olarak incelenmiştir. Akarsuda 22 dalma havuzu tespit edilmiş olup, dalma havuzlarının düşüm yükseklikleri 0.7-20 m, ortalama havuz derinlikleri ise 0.53-1.59 m arasında değişmektedir. Seçilen bir havuzda, havuz derinliği boyunca çözünmüş oksijen (ÇO) konsantrasyonu ve sıcaklığın (Tw) değişimi farklı mevsimlerde incelenmiştir. Veriler, dalma havuzundaki çözünmüş oksijen konsantrasyonunun su sıcaklığıyla ilişkili olarak mevsimsel bağımlılığını ortaya koymuştur. Ayrıca her mevsimde ÇO seviyeleri havuz yüzeyinden havuz tabanına doğru düşüş eğilimi göstermiştir. Özellikle yaz aylarında bir havuzun sıcaklığının ve çözünmüş oksijen seviyelerinin düzenlenmesi açısından nehir kıyısı bitki örtüsünün önemi ortaya konmuştur.

Abstract
In this paper, a forested-mountain stream (Harmankaya) with a catchment area about 12 km2 located in Zonguldak (41ºN-31ºE) on the NW of Turkey has been studied associated with its plunge pools. In the stream, 22 plunge pools were detected and plunge pools drop heights had a variation of 0.7-20 m, whereas average pool depths had a range of 0.53-1.59 m. In a selected pool, the variation of dissolved oxygen (DO) concentration and temperature (Tw) through the pool depth have been investigated at different seasons. The data indicated the seasonal dependence of dissolved oxygen concentration in the plunge pool related to the water temperature. In all seasons DO levels had a downward trend from pool surface to the pool bottom. Riparian vegetation significance has been revealed in terms of regulating the temperature and dissolved oxygen levels of a pool, especially during the summer.
