Abstract:

 The purpose of this study is to determine non-point pollution sources in the Kesikköprü Reservoir basin as well as to estimate the amount of pollution carried into the reservoir by surface flows from non-point sources. Water quality at the Kesikköprü reservoir has been negatively affected by nutrients from non-point pollution sources in the surrounding basin. These sources are identified as actions caused by land use practices agricultural areas, urban zones, meadows, pastures, and natural vegetation areas, fertilizer use for agricultural activities, livestock activities, leaks from individual septic tanks, and atmospheric deposition in the basin. To estimate the pollution from non-point sources, sub-basin boundaries were established by using digital elevation maps within the existing basin boundaries of Kesikköprü Reservoir. The pollution loads namely, total nitrogen TN and total phosphorus TP from non-point sources in sub-basins are calculated for the year of 2022. The areal distributions of the obtained results are presented as digital maps generated by using ArcGIS 10.8, a Geographic Information System GIS software. Non-point pollution loads have been found to occur to a greater extent in the KAH-10 and KAH-2 sub-basins, which have the largest areas among the sub-basins and have a high intensity of anthropogenic activities, in comparison to other sub-basins.

 Bu çalışmanın amacı Kesikköprü baraj gölü havzasında yayılı kirlilik kaynaklarının belirlenmesi ve yayılı kaynaklardan yüzey akışları ile rezervuara taşınan kirlilik miktarının tahmin edilmesidir. Kesikköprü baraj gölündeki su kalitesi, çevresindeki havzadaki yayılı kirlilik kaynaklarından gelen yüklerden olumsuz etkilenmektedir. Bu kaynaklar, arazi kullanım uygulamaları tarım alanları, kentsel alanlar, çayırlar, meralar ve doğal bitki örtüsü alanları, tarımsal faaliyetler için gübre kullanımı, hayvancılık faaliyetleri, bireysel sızdırmalı fosseptikler ve atmosferik birikimlerden kaynaklandığı değerlendirilmektedir. Yayılı kaynaklardan göle ulaşan kirliliği tahmin etmek için Kesikköprü baraj gölünün mevcut havza sınırları içerisindeki alt havzaların sınırları sayısal yükseklik haritaları kullanılarak oluşturulmuştur. Alt havzalardaki yayılı kaynaklardan gelen toplam azot TN ve toplam fosfor TP kirlilik yükleri 2022 yılı için hesaplanmıştır. Elde edilen sonuçların alansal dağılımları ArcGIS 10.8 Coğrafi Bilgi Sistemi CBS yazılımı kullanılarak oluşturulan dijital haritalar halinde sunulmuştur. Yayılı kirlilik yüklerinin, alt havzalar içerisinde en büyük alana sahip olan ve antropojenik faaliyetlerin yoğun olarak yürütüldüğü KAH-10 ve KAH-2 alt havzalarında diğer alt havzalara kıyasla daha fazla miktarda oluştuğu tespit edilmiştir.
