Experimental Study on Scour at a Sharp-Nose Bridge Pier with Debris Blockage
(American Society of Civil Engineers (ASCE), 2018)
Previous experimental research on the effects of debris on pier scour has focused primarily on circular and rectangular piers with debris present just under flow free surface. Debris-induced scour around sharp-nose piers, ...
A normalized regression based regional model for generating flows at ungauged basins
(Water Science and Technology, 2013)
Revision of existing methodologies for generating monthly-flow series at ungauged basins based on multivariate nonlinear correlation has led to a simple two-parameter model. While the existing methodology used hydrological, ...
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 ...
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 ...
Hydraulic Jumps in Adverse-Slope Stilling Basins for Stepped Spillways
(MDPI AG, 2018)
The performance of flat stilling basins can be inadequate for conditions when the tailwater depth is insufficient for hydraulic jump stabilization. In such cases, adverse-slope stilling basins can be used because they ...
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), ...
Drinking water temperature around the globe: understanding, policies, challenges and opportunities
(MDPI, 2020)
Water temperature is often monitored at water sources and treatment works; however, there
is limited monitoring of the water temperature in the drinking water distribution system (DWDS),
despite a known impact on physical, ...
