چکیده
Abstract In this paper, information entropy was proposed to measure water quality reliability in a distribution system (WDS), which had been applied evaluate hydraulic the WDS. evaluation, residual chlorine is representative of quality, and first-order decay model usually adopted. The (R) based on (WQE) improved (Rd) (IWQE) were compared for three networks. method developed EPANET toolkit MATLAB environment. results indicated that flow (FE) strongly related WQE, (IFE) also IWQE. addition, Rd can reflect effect pipe velocity, whereas R only effects WDS layout. novelty paper develop with consideration velocity liability as surrogate index, reduce calculation load be nonlinear system. evaluation help design, analyze, improve

Evaluation of Gorganrood river water quality based on surface water quality indicators in Gonbad Kavous
Background and Objective: Increased untreated wastewater and unsustainable development of agriculture has deteriorated water quality of rivers. The aim of this study was to determine the quality of water in Gorganrud River basin using NSFWQI IRWQISC and Liou Pollution Index and compare them with the global standards. To do this, GIS software.was used Materials and Methods: In this study, 5 sam...
متن کاملDistribution System Indicators of Drinking Water Quality
Background and Disclaimer The USEPA is revising the Total Coliform Rule (TCR) and is considering new possible distribution system requirements as part of these revisions. As part of this process, the USEPA is publishing a series of issue papers to present available information on topics relevant to possible TCR revisions. This paper was developed as part of that effort. The objectives of the is...
متن کاملSeismic-Reliability-Based Optimal Layout of a Water Distribution Network
We proposed an economic, cost-constrained optimal design of a water distribution system (WDS) that maximizes seismic reliability while satisfying pressure constraints. The model quantifies the seismic reliability of a WDS through a series of procedures: stochastic earthquake generation, seismic intensity attenuation, determination of the pipe failure status (normal, leakage, and breakage), pipe...
متن کاملModelling Water Quality for Water Distribution Systems
Maintaining water quality in distribution systems has become a prominent issue in the study of water networks. This thesis concentrates on disinfectant and particle counts as two important indicators of water quality. The models discussed in this work are based on data collected by the author. The experimental set-up and procedure are described and observations of particle counts, particle coun...
متن کاملEffect of water current on some growth performance and water quality in a closed rainbow trout (Oncorhynchus mykiss) culture system
The effects of water current increment on rainbow trout ( Oncorhynchus mykiss ) culture were investigated during a 35 day experiment. Fish weighing 5.5 g were stocked in aquarium tanks. Four different water speeds (0, 3.5, 7, 10.5 cm/s) were provided for each treatment in three replicates. These different currents water were provided by reusing outlet water of each culture unit...
