AB  - Akarsular tarafından taşınan sediman miktarları, jeokimyasal döngünün, havzadaki toprak kayıplarının, erozyon oranlarının ve denüdasyon süreçlerinin bir göstergesi olarak kabul edilir ve her yıl dünya genelinde akarsuların yaklaşık 20 milyar ton sedimanı okyanus ve denizlere taşıdığı tahmin edilmektedir. Flüvyal süreçlerle taşınan sediman oran ve miktarları üzerine yapılan birçok çalışma süspanse halinde taşınan katı sedimana odaklanmış, taşınan eriyik madde oran ve miktarları genellikle ihmal edilmiştir. Her ne kadar süspanse sedimanlar akarsulardaki sediman yükünün önemli bir bölümünü oluştursa da özellikle çözünebilen kayaçların yaygın olduğu sahalarda akarsularda eriyik halde taşınan sediman toplam sediman yükünün önemli bir bölümünü oluşturabilir. Bu çalışmada, toplamda 12 aylık bir ölçüm döneminde Korkuteli Çayı’nda taşınan eriyik sediman miktarları ve konsantrasyon değerleri belirlenerek eriyik sediman ile akım ve yağış arasındaki ilişki ortaya konulmuştur. Akarsuyun akım (debi) ve eriyik sediman süreçlerini belirlemek için 10’ar dakikalık sürelerle Mesens (MPS580 Serisi) Marka Daldırma Tipi Seviye Transmitteri kullanılarak otomatik olarak su seviyeleri ölçüldü. Suyun hızı, belirli aralıklarla Universal Muline cihazı ile belirlenmiş ve eriyik sediman örnekleri ise US-DH48 derinlik entegrasyon örnekleyicisi kullanılarak alınmıştır. Alınan su ve sediman numunelerinin laboratuvar ortamında filtrasyon yöntemi ile analiz edilmiştir. Bulgular; eriyik sediman konsantrasyon değerleri ile akım miktarları arasında polinomsal pozitif bir ilişki olduğunu ortaya koymuştur (R2: 0.96). Kış döneminde bölge genelinde daha çok düşük yoğunluklu, uzun süreli yağışların etkisiyle akım değerlerinde ani artma ve azalma yerine daha çok taban akışı veya buna yakın bir akış seyri göstermiştir.  Düşük yoğunluklu, uzun süreli yağışların meydana geldiği kış döneminde akım miktarlarının daha düşük olması nedeniyle taşınan eriyik sediman miktarları daha az, ancak su içerisindeki eriyik konsantrasyonunun yaz aylarına oranla daha yüksek olduğu belirlenmiştir. Yaz döneminde özellikle Haziran ayında oluşan yüksek yoğunluklu, kısa süreli sağanak yağışlar akım miktarlarının yıl içerisinde tespit edilen en yüksek değerlere erişmesi sonucunu doğurmuş ve böylece, düşük eriyik madde konsantrasyonuna rağmen, miktar olarak daha fazla eriyik sediman taşınımı gerçekleşmiştir.

N2  - The sediment transported by rivers are considered an indicator of the geochemical cycle, soil losses, erosion rates and denudation processes, and it is estimated that rivers transport approximately 20 billion tons of sediment to oceans and seas each year. Many studies on sediment transported by fluvial processes have focused on solid sediment in suspended form, and the dissolved sediment transported has generally been neglected. Although suspended sediments constitute a significant part of the sediment load in rivers, the dissolved sediment, especially in areas where soluble rocks are common, may constitute a large amount of the total sediment load. The aim of this study is to analyze dissolved sediment variability over a period of 12 months in the Korkuteli Stream, and to evaluate the relationship between water discharge, dissolved sediment and precipitation. The water level recorded automatically every 10 minutes using a Mesens (MPS580 Series) Immersion Type Level Transmitter and the water velocity was measured with a Universal Current Meter. The sediment samples were taken using a US-DH48 depth integration sampler and were analyzed by filtration method in laboratory. Results show that a strong relationship exists between flow and dissolved sediment concentration (R2: 0,96). During the winter period, the discharge showed a regular pattern flow characteristics rather than a sudden fluctuation observed in spring and summer months due to low intensity and long-term precipitation in winter months. The results revealed that, unlike the summer months, which are characterized by short-term heavy rainfall events, the amount of dissolved sediment transported during the winter months is less due to low intensity long duration of rainfall events. High intensity, heavy rainfall during the summer period, especially in June, resulted in the amount of discharge reaching the highest values and thus, despite the low dissolved concentration, greater amount of dissolved sediment transport was measured.
