Bu çalışmada, sulama suyu amaçlı kullanılan Aydınlar (Gülüç) çayının fiziko-kimyasal parametreler açısından su kalitesi incelenmiş ve insansız hava aracı (İHA) verilerinin spektral analizi ile karşılaştırmalı değerlendirmeleri yapılmıştır. Çalışma kapsamında, su kalitesini belirlemek için üç farklı numune alım noktası belirlenmiş ve Haziran 2019 (kurak dönem), Eylül 2019 ve Aralık 2019 (yağışlı dönem) tarihlerinde çayı temsilen su numuneleri alınmıştır. Alınan numunelerin pH, elektriksel iletkenlik (Eİ), bulanıklık, askıda katı madde (AKM), sıcaklık değerleri ile kimyasal oksijen ihtiyacı (KOİ), biyokimyasal oksijen ihtiyacı (BOİ5), çözünmüş oksijen (ÇO), toplam kjeldahl azotu (TKA), toplam fosfat (TP) ve yağ-gres analizleri gerçekleştirilmiştir. pH, Eİ, bulanıklık, sıcaklık ve AKM değerleri sırasıyla ortalama 7.67-8.32, 815-1106 µS/cm, 14.91-20.95 NTU, 9.34-25.34 °C ve 32.84-82.67 mg/L arasında, ÇO, BOİ, KOİ, TP, TKA ve yağ-gres değerleri ise sırasıyla ortalama 2.34-3.40 mg/L, 8.14-20.14 mg/L, 96.44-132.7 mg/L, 0.179-0.296 mg/L, 13.91-20.14 mg/L ve 0.0087-0.016 mg/L arasında ölçülmüştür. Tespit edilen fiziko-kimyasal parametreler Yerüstü Su Kalitesi Yönetmeliği (YSKY)’ne göre değerlendirilmiştir. Ayrıca, belirlenen fiziko-kimyasal parametrelerin su yüzeyinde meydana getirdiği spektral (renk) değişimler, yüksek çözünürlüklü kamera donanımına sahip İHA ile elde edilen hava fotoğraflarının işlenmesi sonucu üretilen ortomozaikler üzerinden analiz edilmiştir. Sonuç olarak, Aydınlar Çay’ının ÇO, BOİ5, KOİ, TP ve TKA ortalama konsantrasyonları YSKY’in de belirtilen değerlere göre III. Sınıf ve IV. Sınıf su kalite özelliği gösterdiği tespit edilmiştir.
In this study, the quality of the water was studied in terms of the physico-chemical parameters of the Light (Smile) tea used for the purposes of irrigation water and comparative assessments were made with the spectral analysis of the data of the unmanned aircraft (IHA). In the framework of the study, three different sampling points were determined to determine water quality and water sampling were taken represented by the tea in June 2019 (dry period), September 2019 and December 2019 (dry period). The samples were taken with pH, electrical conductivity (EI), humidity, suspended solid substance (AKM), chemical oxygen need (COI), biochemical oxygen need (BOI5), solved oxygen (COO), total keldahl nitrogen (TKA), total phosphate (TP) and oil-gres analysis. The pH, EI, humidity, temperature and ACM values are measured between 7.67-8.32, 815-1106 μS/cm, 14.91-20.95 NTU, 9.34-25.34 °C and 32.84-82.67 mg/L respectively, while the CHO, BOI, KOI, TP, TKA and oil-gres values are measured between 2.34-3.40 mg/L, 8.14-20.14 mg/L, 96.44-132.7 mg/L, 0.179-0.296 mg/L, 13.91-20.14 mg/L and 0.0087-0.016 mg/L respectively. The identified physical and chemical parameters are assessed according to the Surface Water Quality Regulation (YSKY). Furthermore, the spectral (colour) changes in which determined physical-chemical parameters occur on the water surface have been analyzed through the ortomosaics produced as a result of the processing of the air photographs obtained by IHA with high-definition camera equipment. As a result, the average concentrations of Light Tea are CHO, BOI5, KOI, TP and TKA according to the indicated values of YSKY III. Class and IV. The class of water has shown its quality characteristics.
In this study, the water quality of Aydınlar (Gülüç) Stream, which is used for irrigation, has been examined in terms of physico-chemical parameters and comparative evaluations were realized with spectral analysis of unmanned aerial vehicle (UAV) data. Within the scope of this study, we determined three distinct locations to collect water samples for evaluation and water samples were taken to represent the water quality of the stream in the periods such as, June 2019 (dry period) and September and December 2019 (rainy periods). The samples were evaluated in terms of their pH levels, electrical conductivities (EI), turbidities, total suspended solids (TSS), temperature values and chemical oxygen demands (COD), biochemical oxygen demands (BOD5), dissolved oxygen (DO) levels, total kjeldahl nitrogen (TKN), total phosphate (TP) and oil-grease analysis. Average pH, conductivity, turbidity, temperature and TSS values were measured respectively, 7.67-8.32, 815-1106 µS/cm, 14.91-20.95 NTU, 9.34-25.34 °C and between 32.84-82.67 mg/L; DO, BOD5, COD, TP, TKN and oil-grease values measured average respectively as; 2.34-3.40 mg/L, 8.14-20.14 mg/L between 96.44-132.7 mg/L, 0.179-0.296 mg/L, 13.91-20.14 mg/L and 0.0087-0.016 mg/L. Detected physico-chemical parameters have been evaluated according to the Surface Water Quality Regulation (SWQR). In addition, the determined spectral changes on the water surface caused by the physico-chemical parameters were analyzed over generated ortho-mosaics by processing aerial photos obtained with high-resolution camera equipped UAV. As a result, we can state that Aydınlar Stream's water’s average concentrations of DO, BOD5, COD, TP and TKN levels, according to the values specified in SWQR, show III. class and IV class water quality properties.
