Improved Loop-Flow Method for Hydraulic Analysis of Water Distribution Systems
(American Society of Civil Engineers (ASCE), 2018)
Different methods have been developed in the past to formulate and solve steady-state hydraulics of a water distribution system (WDS). The most widely used method nowadays is probably the global gradient algorithm (GGA). ...
Hydrodynamic effects of debris blockage and scour on masonry bridges: Towards experimental modelling
(CRC Press/Balkema, 2016)
This paper describes the preliminary stage of an ongoing project investigating the hydrodynamic effects of debris blockage at masonry bridges. Debris blockage is cited as one of the primary causes of bridge failures in the ...
On the combined effect of bed elevation discordances in the main-river and the tributary in 90° straight-channel confluences
(CRC Press/Balkema, 2016)
The role of the difference in bed elevations in the main-river (ΔzMR) and the tributary (ΔzT) at their entrance to a 90° straight-channel confluence is studied numerically using a 3D finite-volume model. Three characteristic ...
Water level and discharge measurements in: Metrology in Urban Drainage and Stormwater Management: Plug and Pray
(IWA Publishing, 2021)
The knowledge of water levels and discharges in urban drainage and stormwater management (UDSM) systems is of key importance to understand their functioning and processes, to evaluate their performance, and to provide data ...
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 ...
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 ...
The antimicrobial efficiency of silver activated sorbents
(Elsevier B.V., 2015)
This study is focused on the surface modifications of the materials that are used for antimicrobial water treatment. Sorbents of different origin were activated by Ag+-ions. The selection of the most appropriate materials ...
Ecological risk assessment for different macrophytes and fish species in reservoirs using biota-sediment accumulation factors as a useful tool
(Elsevier Ltd, 2018)
Metal content was evaluated in the sediment, macrophytes and fish in the Medjuvrtje reservoir (Western Serbia). Concentrations of 16 trace elements (Ag; Al; As; B; Ba; Cd; Co; Cr; Cu; Fe; Li; Mn; Ni; Pb; Sr; Zn) were ...
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 ...
