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 ...
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 ...
Computation of Thermal-Stresses and Contraction Joint Distance of RCC Dams
(Journal of Thermal Stresses, 2013)
A new approach in 3D numerical modeling for unsteady phased thermal-stress analysis of a massive concrete hydraulic structure is presented. The temperature field is computed first, providing a drive for the unsteady, ...
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 ...
Estimation of 1D-confluence model parameters in right-angled discordant beds’ confluences using 3D numerical model
(CRC Press/Balkema, 2016)
Parameters of 1D confluence models are originally defined for concordant beds’ (CB’s) confluences. This paper aims at estimating these parameters for discordant beds’ confluences using numerical simulation results of 3D ...
The 3DNet-Catch hydrologic model: Development and evaluation
(Elsevier B.V., 2019)
Hydrologic models are important for effective water resources management. They vary in complexity from parsimonious, spatially lumped, to physically-based, fully distributed models, which are generally expected to outperform ...
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 ...
New approach: waste materials as sorbents for arsenic removal from water
(Publication Cover Journal of Environmental Engineering, 2010)
The sorption of inorganic arsenic species arsenite and arsenate from aqueous solutions onto steel-mill waste and waste filter sand, under neutral conditions, was investigated in this study. Additionally, the steel-mill ...
Development and application of numerical method in open channel flow in boundary fitted coordinate system with density function method
(Journal of Japan Society of Civil Engineers, Ser. B1 (Hydraulic Engineering), 2016)
