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. ...
Numerical Simulation of 3D Flow at Right-angled Confuence with and without Upstream Planform Curvature
(Chemical Industry Press, Beijing, 2010)
This paper aims at studying the effect of upstream planform curvature on the flow in the confluence hydrodynamics zone. To do this, a 3D numerical model is used for simulation of flow at right-angled
confluences with ...
Advanced simulation and modelling for urban groundwater management / Chapter 2. UGROW – the Urban GROund Water modelling system
(UNESCO-IHP 7, Urban Water series, Taylor&Francis, 2010)
Historically, the vital role that groundwater plays in the urban water cycle has been
severely neglected. To a certain extent this reflects an ‘out of sight, out of mind’ mentality, resulting in ignorance of subsurface ...
Integrated hydrological information system for northern Algeria
(IAHS-AISH Publication, 2010)
As a result of cooperative work of experts from Algeria (ANRH) and Serbia (Energoprojekt with the assistance of Belgrade University) through the project CRESNA (Carte des Ressources en Eau Souterraines du Nord de l'Algerie), ...
Numerical modeling of dissolved oxygen recovery during aeration in lakes
(Environmental Hydraulics - Proceedings of the 6th International Symposium on Environmental Hydraulic, 2010)
One of available lake restoration technologies is injection of compressed air or oxygen into a hypolimnion, promoting vertical mixing of water and dissolution of oxygen.A numerical model has been developed for simulation ...
Automatic, semi-automatic and manual validation of urban drainage data
(Water Science and Technology, 2010)
Advances in sensor technology and the possibility of automated long distance data transmission have made continuous measurements the preferable way of monitoring urban drainage processes. Usually, the collected data have ...
Determination of inorganic arsenic species in natural waters-Benefits of separation and preconcentration on ion exchange and hybrid resins
(Analytica Chimica Acta, 2010)
A simple method for the separation and determination of inorganic arsenic (iAs) species in natural and drinking water was developed. Procedures for sample preparation, separation of As(III) and As(V) species and preconcentration ...
Long-term thermal two- and three-dimensional analysis of roller compacted concrete dams supported by monitoring verification
(Canadian Journal of Civil Engineering, 2010)
This paper presents two-dimensional (2D) and three-dimensional (3D) numerical models for unsteady phased thermal analysis of RCC dams. The time evolution of a thermal field has been modeled using the actual dam shape, RCC ...
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 ...
Ski jump design
(Proceedings of the Institution of Civil Engineers-Water Management, 2010)
This paper is concerned with ski jump design for overflow dams and chute spillways. Despite the vast scope of literature on this subject, research in this field is still needed. Three important issues are addressed: take-off ...
