Abstract

Atmosferik yeniden havalandırma süreci, nehirlerde ve akarsularda çözünmüş oksijen (DO) konsantrasyonlarını etkileyen organik maddenin bozunmasında ve kendi kendini saflaştırma süreçlerinde kilit bir rol oynar. Ayrıca, su kalitesi (WQ) süreçleri büyük ölçüde akış hızı koşullarına bağlı olabilir. Burada, yüksek yeniden havalandırma oranları, yüksek akış hızı ile pozitif olarak ilişkilidir. Bu nedenle, mevcut çalışma, DO konsantrasyonunda ve biyokimyasal oksijen ihtiyacında (BOD5) yeniden havalandırma işlemi ile akış hızının rolü hakkında derin görüşler bildirmektedir. Bu çalışma, Mısır'daki en büyük tarımsal drenaj suyu yeniden kullanım projesi olan El-Salam Kanalı boyunca uygulandı. Kanal boyunca hidrodinamik (HD) özellikler ve WQ parametreleri (DO ve BOD5), tek boyutlu bir HD ve WQ modeli (MIKE 11) kullanılarak simüle edilmiştir. Simüle edilen sonuçlar, kanalın El-Serw ve Bahr Hadous drenleri ile karıştırıldıktan sonra El-Salam Kanalı'na doğru bozulduğunu gösterdi. Yeniden havalandırma hızlarının simülasyon sonuçları üzerinde, akış hızı ve WQ değerleri ile istatistiksel regresyon uydurma çizgisi ve Pearson korelasyon analizi yapılmış ve önemli bir korelasyona işaret edilmiştir. Buna göre, su hızı, WQ değişimini açıklamak için kilit bir faktör olarak dikkate alınmalıdır.

Quantitative study for the effect of water velocity on water quality change

Abstract

Atmospheric reaeration process plays a key role in degradation of organic matter and self-purification processes affecting dissolved oxygen (DO) concentrations in rivers and streams. Moreover, water quality (WQ) processes can be highly dependent on flow velocity conditions. Where, highly reaeration rates are positively correlated with high flow velocity. Therefore, the present work reports deep insights on the role of flow velocity with reaeration process in the concentration of DO and biochemical oxygen demand (BOD5). This study was applied along the largest agricultural drainage water reuse project, El-Salam Canal in Egypt. The hydrodynamic (HD) characteristics and WQ parameters (DO and BOD5) along the canal were simulated using a one-dimensional HD and WQ model (MIKE 11). The simulated results indicated that the canal was deteriorated towards El-Salam Canal after mixing with El-Serw and Bahr Hadous drains. Statistical regression fitted line and Pearson correlation analysis, were performed on the simulation results of the reaeration rates with flow velocity and WQ values, indicating a significant correlation. Accordingly, water velocity should be taken into account as a key factor for describing the WQ change.
