Enhanced DEM-based flow path delineation methods for urban flood modelling
(IWA Publishing, 2013)
In order to simulate surface runoff and flooding, one-dimensional (1D) overland flow networks can be automatically delineated using digital elevation models (DEM). The resulting network comprises flow paths and terrain ...
Shaft spillway with deflector downstream of vertical bend
(Thomas Telford Services Ltd, 2014)
This study considers the hydraulic design of a shaft spillway with a constriction at the upstream end of the vertical bend. The effect of key factors relating to the capacity of the crest, shaft and tunnel is assessed using ...
Numerical modelling of supercritical flow in circular conduit bends using SPH method
(China Ocean Press, 2017)
The capability of the smoothed-particle hydrodynamics (SPH) method to model supercritical flow in circular pipe bends is considered. The standard SPH method, which makes use of dynamic boundary particles (DBP), ...
Inefficiency of storm water inlets as a source of urban floods
(IWA Publishing, 2005)
The paper attempts to explain sources of surplus storm water runoff in urban areas, particularly in relation with functioning of inlets. Inlet capacity (quantity of captured water) and inlet efficiency (portion of the ...
Converging stepped spillway flow
(Taylor and Francis Ltd., 2016)
Wall deflection in supercritical flow induces standing waves which significantly influence the flow field close to the wall. This paper analyses the flow in the converging stepped spillway, using two scale-models with ...
The influence of digital elevation model resolution on overland flow networks for modelling urban pluvial flooding
(IWA Publishing, 2009)
This paper presents the developments towards the next generation of overland flow modelling of urban pluvial flooding. Using a detailed analysis of the Digital Elevation Model (DEM) the developed GIS tools can automatically ...
SIPSON - Simulation of interaction between pipe flow and surface overland flow in networks
(IWA Publishing, 2005)
The new simulation model, named SIPSON, based on the Preissmann finite. difference method and the. conjugate gradient method, is presented in the paper. This model simulates conditions when the hydraulic capacity of a sewer ...
Measurement, calibration of rainfall-runoff models and assessment of the return period of flooding events at urban catchment Kumodraz in Belgrade
(IWA Publishing, 2002)
For the purpose of re-design and improvement of the combined sewer system at the Kumodraz catchment in Belgrade, measurements of rainfall and runoff at the catchment were established in late 1997, Observed data are used ...
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 ...
Numerical study of 3D flow at right-angled confluences with and without upstream planform curvature
(IWA Publishing, 2013)
The purpose of this paper is to study the individual and combined effect of upstream planform curvature and difference in bed elevations at the tributary entrance to the confluence on the flow in the confluence hydrodynamics ...
