Investigation and analysis of college's water system: the case of Northeastern University
To date there have been many studies of water system optimization which were focused on the water use performance of industrial, regional, and urban areas from a macro-perspective. However, water system optimization colleges and universities are rare, though the amount of water consumption is huge in higher education institutions. We applied a water extended input–output model to investigate ...

Bayesian modelling for water loss management decisions
Bayesian networks and their associated methods are especially suited for capturing and dealing with uncertainty. They can be successfully applied both in engineering sciences and in reliability analyses of water distribution systems. In this paper we propose an interactive Bayesian network and a decision-theoretic system which intend to monitor water loss, predict likely outcome and select ...

Adaptable urban water demand prediction system
In this work, identification of 24-hours-ahead water demand prediction model based on historical water demand data is considered. As part of the identification procedure, the input variable selection algorithm based on partial mutual information is implemented. It is shown that meteorological data on a daily basis are not relevant for the water demand prediction in the sense of partial mutual ...

Water resources planning and management for Chennai City using decision support system
Managing the water resources thoughtfully and profitably is the most crucial responsibility. This paper aims to study and analyse the water supply system at city level with the help of simulation technique and Decision Support System (DSS). In this study, the capital of Tamil Nadu (India), Chennai City is considered. The study analyses the existing level of water supply and it tries to fill the ...

We Need to Talk About Peaking Factors
In the design of water networks ‘peaking factors’ are used for simulating design flows in hydraulic models. In simple terms, the dimensionless peaking factor is maximum over average consumption. Historically, utilities adopted standardized peaking factors based on their source data (treatment plant etc.) which was the most reliable source of data. But as we enter the world of big ...

Combined risk prediction in the water environment based on an MS–AR model and Copula theory
Making a quantitative prediction on the combined risk of the water body is helpful for the objective evaluation of the water environment system's state of health, and also has important results for the water environment system's safety management. In this paper, the Markov status switching theory (Markov Switching, MS), Monte Carlo method (Monte Carlo, MC) and Copula theory were ...

Spatial analysis of water quality using a combination of GIS and statistical software
GIS-based spatial analysis was combined with statistical analysis to process time varying water quality data. A data model was employed to manage the spatio-temporal data. The spatial data engine of ArcSDE was used to access the database. A data relationship model was developed to perform data communication between GIS and the statistical software. Visual Basic was used to construct links between ...

Leakage discharge separation from the total water supply flow in water distribution system by constrained independent component analysis (CICA)
The blind source separation theory was introduced and the trend and amplitude (TAA) model was established in order to overcome the shortcomings of some traditional global leakage discharge analysis models in water distribution systems (WDS). The TAA model considers the leakage discharge as one part of the total water supply flow, consisting of constrained independent component analysis (CICA) ...

Resilience-based failure mode effects and criticality analysis for regional water supply system
An alternative risk assessment method, known as failure mode effects and criticality analysis (FMECA), is demonstrated on the regional water supply systems (RWSS) in Tucson, AZ, USA that combines delivery of potable and reclaimed water and conveyance of wastewater to a developing area within the Tucson RWSS. The goal of FMECA is to examine the volumetric severity of a component failure on the ...
