Numerical stability problems in hydrodynamic modelling of confluences with small junction angles
(Universidad de Concepción, 2009)
The paper addresses problems which arise from the use of 3D grids with quadrilateral faces on
the horizontal planes in hydrodynamic modelling of discordant beds asymmetrical confluences
with small junction angles. There ...
Velocity field and discharge measurements at the turbine inlet of Iron Gate 2 hydropower plant
(European Geosciences Union/Copernicus Publications, 2021)
To define the performance characteristics of turbines in Hydropower Plants (HPP) accurate hydraulic, mechanical and electrical quantities are needed. The discharge is the most difficult quantity to measure and assess its ...
Influence of small water storage reservoirs on reliability of irrigation water supply
(Macedonian Committee on Large Dams, 2021)
The paper analyses the consequences of climate change on the irrigation water demand and the impact of water storage reservoirs on increasing the reliability of irrigation water supply. Analyses were performed for the Vrbas ...
Experimental investigation of scour and pressures on a single span arch bridge under inundation
(Utah State University, 2018)
This paper presents two experiments, carried out in a 605mm-wide flume, to investigate scour and hydrodynamic pressure on a scaled model of a single span arch bridge. The geometry of the bridge model is scaled down according ...
Goethite nanoparticles impregnated cross-linked macroporous polymer for arsenic removal: fullscale system modeling
(Abstracts of Papers of the American Chemical Society, 2015)
Online time data series pre-processing for the improved performance of anomaly detection methods
(Integrating Water Systems - Proceedings of the 10th International on Computing and Control for the W, 2010)
The number of automated measuring and reporting systems used in water distribution and sewer systems is dramatically increasing and, as a consequence, so is the volume of acquired data. Since the real time data is likely ...
Consequences of non planned urban development during turbulent times in Serbia - case study of suburb Kumodraz watershed in Belgrade
(Risk Management of Water Supply and Sanitation Systems, 2009)
Development is usually based oil numerous analyses accounting for planning, economy and population assessments as well as urbanism, architectural and civil engineering infrastructure planning and project design. The modern ...
On the effect of the bed morphology on the river confluence hydrodynamics
(Proceedings of the International Conference on Fluvial Hydraulics - River Flow 2006, 2006)
A river confluence is known for the strong three-dimensional flow effects. The confluence hydrodynamics is significantly influenced by the river bed morphology. Two morphological features are typical for river confluences: ...
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 ...
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 ...
