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 ...
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 ...
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 ...
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 ...
Incorporating stakeholders’ preferences into a multi-criteria framework for planning large-scale Nature-Based Solutions
(Ambio, 2020)
Hydro-meteorological risks are a growing issue for societies, economies and environments around the world. An effective, sustainable response to such risks and their future uncertainty requires a paradigm shift in our ...
A comparison of tools and techniques for stabilising unmanned aerial system (UAS) imagery for surface flow observations
(Copernicus, EGU, 2021)
While the availability and affordability of unmanned aerial systems (UASs) has led to the rapid development of remote sensing applications in hydrology and hydrometry, uncertainties related to such measurements must be ...
Circular Economy in Construction and Demolition Waste Management in the Western Balkans: A Sustainability Assessment Framework
(Sustainability, 2022)
Population growth, consumerism and linear (take-make-dispose) economy models have been piling up waste for decades. The construction industry is also based primarily on linear economy models, but the good news is that most ...
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 simulation of non-rigid landslide into reservoir with erodible sediment bed using SPH method
(SpringerInternational Association for Engineering Geology and the Environment (IAEG), 2021)
Landslide phenomenon in accumulated erodible bed sediments in a reservoir is one of the issues in hydraulic and sedimentation sciences that has received little attention. We intend to model two-dimensional changes of the ...
Flood protection and water utilization of karst poljes: example of Gatačko Polje, Eastern Herzegovina
(Springer, 2020)
Eastern Herzegovina is highly karstified area, with porosity of karstified rock mass between 0.8 and 2%. It is an area with high precipitation (average annual values in wet year are around 2450 mm), but its distribution ...
