The Different Impact of a Half-Separated Gravel and Vegetated Bed in Open Channels
(2015)This paper investigates the different impact of a half-separated gravel and vegetated bed in open channels. This experimental investigation is based on the 2D Particle Image Velocimetry (PIV) method, which allows data ... -
Experimental study of the effects of grass vegetation and gravel bed on the turbulent flow using particle image velocimetry
(2015)Laboratory experiments are used to explore the effect of impermeable bed on the turbulent flow by using particle image velocimetry (PIV). The experiments were conducted in an open channel of 6.5 m length, 7.5 cm width and ... -
Morphological - Functional Aspects of Electro-Discharge Machined Surface Textures
(2009)This study investigates a set of "non-common" surface topography parameters of Electro-Discharge Machined surfaces that give differing aspects of texture related to morphological characterization and possible tribological ... -
Probabilistic flood inundation mapping at ungauged streams due to roughness coefficient uncertainty in hydraulic modelling
(2017)Probabilistic flood inundation mapping is performed and analysed at the ungauged Xerias stream reach, Volos, Greece. The study evaluates the uncertainty introduced by the roughness coefficient values on hydraulic models ...
