Online time data series pre-processing for the improved performance of anomaly detection methods
(Integrating Water Systems - Proceedings of the 10th International on Computing and Control for the W, 2010)
The number of automated measuring and reporting systems used in water distribution and sewer systems is dramatically increasing and, as a consequence, so is the volume of acquired data. Since the real time data is likely ...
PID Controllers as Data Assimilation Tool for 1D Hydrodynamic Models of Different Complexity
(Springer, 2019)
Flood risks management is based on data obtained by different forecasts. Forecasts are often based on hydrological-hydrodynamic models. These models are calibrated using selected time-series from the past. However, even ...
Building a Sustainable Water Management System in the Republic of Serbia: Challenges and Issues
(American Chemical Society, 2015)
The Republic of Serbia is a good example of a developing country with a water management system that has not been adequately transitioned to address the need of the new socio-economic paradigm. Consequently, more than 30% ...
Identification of leak characteristics in pipe systems by dynamic monitoring
(Integrating Water Systems - Proceedings of the 10th International on Computing and Control for the W, 2010)
The paper presents some reflections about use of hydraulic transients in identification of pipe system characteristics. Controlled and safe transients can be used to excite pipe network to respond to change in flows/pressures. ...
Application of 3D numerical models in confluence hydrodynamics modelling
(University of Illinois at Urbana-Champaign, 2012)
In this paper performance of the SSIIM2 model (3D finite-volume model with the k-ε-type turbulence model closure) in confluence hydrodynamics modelling is assessed using the published experimental ...
Improving quality of drinking water in the water treatment plant by decrease of hardness with respect to sodium concentration control
(Prague, Czech Republic: University of Chemistry and Technology, 2019)
In this research the object of the analysis was the groundwater used for drinking which needs certain improvements. Improvements involve removal of magnesium and manganese. Improvements also mean the choice of proper water ...
Influence of organic acid treatement on recycled concrete aggregate
(XIV International Scientific Conference iNDiS 2018 and Subconference "Eco build", 2018)
As a result of increasing global environmental awareness and sense of responsibility for future generation lives, utilization of demolition waste as potential aggregate for structural concrete has been proposed. Reducing ...
Management of Multipurpose Resources Systems in Areas Vulnerable to Floods
(Macedonian Committee on Large Dams, 2019)
Floods are natural events that have occurred since the earliest times, endangering people, their settlements and property. As a consequence of climate changes and changes in the catchment area (changes in land use, ...
Experimental investigation of scour and pressures on a single span arch bridge under inundation
(Utah State University, 2018)
This paper presents two experiments, carried out in a 605mm-wide flume, to investigate scour and hydrodynamic pressure on a scaled model of a single span arch bridge. The geometry of the bridge model is scaled down according ...
Numerical simulation of 3D flow at 90o straight-channel confluence with bed elevation discordance
(TuTech Verlag, TuTech Innovation GmbH, 2012)
The paper aims at studying the effect of difference in bed elevations between the tributary and main canals (∆zT) on the flow in the confluence hydrodynamics zone. To do this, a 3D numerical model is used for flow simulation ...
