Abstract

Leaks occur at different rates in water distribution systems (WDSs). Network characteristics, high pressure, environmental factors and operational factors are effective on leaks. Field detection and monitoring activities should be implemented to reduce the volume of leaks resulting from faults in the WDS. The aim of this study is to create and calibrate the district metered area (DMA) based hydraulic model to understand the network behavior and monitor the hydraulic components. The hydraulic model is based on consumption data, network topology, characteristics and pipe roughness information. Calibration should be performed by comparing the pressures obtained from the model with the pressures measured in the field in order to apply the model in leakage management. Incomplete or incorrect network information may cause the difference between these two pressures to be large. In particular, basic data such as incomplete creation of the network topology, incomplete or incorrect acquisition of roughness and consumption information are effective in not providing model calibration. In the calibrated hydraulic model, it is possible to detect and prevent potential leaks by monitoring pressure changes at the nodes. It is thought that the results obtained in this study will constitute a reference in leakage management and hydraulic analysis.

Abstract

İçmesuyu dağıtım sistemlerinde farklı oranlarda sızıntı meydana gelmektedir. Sızıntılar üzerinde şebeke özellikleri, yüksek basınç, çevresel faktörler ve işletme faktörleri etkilidir. Dağıtım sisteminde arızalardan kaynaklanan sızıntı hacminin azaltılması için sahada tespit ve izleme faaliyetleri uygulanmalıdır. Bu çalışmada, şebeke davranışının anlaşılması ve hidrolik bileşenlerin izlenmesi için İzole Ölçüm Bölge bazlı hidrolik modelin oluşturulması ve kalibrasyonu amaçlanmıştır. Hidrolik modelde, tüketim verileri, şebeke topolojik, karakteristik ve boru pürüzlülük bilgileri esas alınmaktadır. Modelin sızıntı yönetiminde uygulanabilmesi için modelden elde edilen basınçlar sahada ölçülen basınçlar ile kıyaslanarak kalibrasyon yapılmalıdır. Şebeke bilgilerinin eksik veya hatalı alınması bu iki basınç arasındaki farkın fazla olmasına neden olmaktadır. Model kalibrasyonunun sağlanmamasında özellikle, şebeke topolojisinin eksik oluşturulması, pürüzlülük ve tüketim bilgilerinin eksik veya yanlış alınması gibi temel veriler etkili olmaktadır. Kalibre edilmiş hidrolik modelde, düğüm noktalarında basınç değişimleri izlenerek potansiyel sızıntıların farkına varılması ve önlenmesi mümkün olmaktadır. Bu çalışmada elde edilen sonuçların sızıntı yönetiminde ve hidrolik analizinde referans oluşturacağı düşünülmektedir.
