Uncertainty reduction in water distribution network modelling using system inflow data
(Urban Water Journal, 2009)
In water distribution network (WDN) modelling, nodal demand is the sum of flows taken by users associated with a computational node. User demands are not fixed in time; rather they are stochastic. Hence, nodal demand is a ...
Sensitivity Analysis of a Physically Based Distributed Model
(Springer Netherlands, 2016)
The objective of this study is to perform a sensitivity analysis of the SHETRAN model on the example of the torrential Lukovska River catchment in Serbia. The sensitivity analysis of the model was performed for the following ...
The validation of stormwater biofilters for micropollutant removal using in situ challenge tests
(Elsevier, 2014)
Stormwater harvesting is becoming a popular alternative water resource in water stressed regions. Stormwater biofilters have been recognized as being among the most promising pre-treatment technologies. In this study, a ...
Simulation of transcritical flow in pipe/channel networks
(ASCE - American Society of Civil Engineers, 2004)
Using finite difference methods in conjunction with the reduced momentum equation and applying boundary condition structure inherent to subcritical flow to all regimes, is an approach that enables efficient numerical ...
Overland flow and pathway analysis for modelling of urban pluvial flooding
(Journal of Hydraulic Research, 2009)
Research on improving an overland flow model is presented for urban pluvial flooding under the dual-drainage concept where sewer flow dynamically interacts with overland flow. This occurs during heavy storms when the sewer ...
Towards harmonisation of image velocimetry techniques for river surface velocity observations
(Copernicus Publications, 2020)
Since the turn of the 21st century, image-based velocimetry techniques have become an increasingly popular approach for determining open-channel flow in a range of hydrological settings across Europe and beyond. Simultaneously, ...
Uniformity and Heuristics-Based DeNSE Method for Sectorization of Water Distribution Networks
(Reston, VA (USA): ASCE - American Society of Civil Engineers, 2020)
Sectorization of a water distribution network (WDN) into district metered areas (DMAs) is a proven solution for proactive leakage control. Traditionally, WDN sectorization is conducted by local experts using a trial-and-error ...
Calibration of a 1D/1D urban flood model using 1D/2D model results in the absence of field data
(Water Science and Technology, 2011)
Recently increased flood events have been prompting researchers to improve existing coupled flood-models such as one-dimensional (1D)/1D and 1D/two-dimensional (2D) models. While 1D/1D models simulate sewer and surface ...
Improvement of chemical control in the water-steam cycle of thermal power plants
(Applied Thermal Engineering, 2011)
A more effective chemical control in the water-steam cycle (WSC) of thermal power plants (TPP) is proposed in this paper. Minimization of corrosion effects by the production of ultra pure water and its strict control is ...
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 ...
