Bedload transport through emergent vegetation: current status and its future prospect Open
Vegetation present in the water streams, on the banks and in the floodplain areas largely affects the river hydraulics. Indeed, river vegetation significantly influences hydrodynamics, sediment transport, bedforms, and pollutant transport.…

Triggering of Rain-Induced Landslides, with Applications in Southern Italy Open
Landslides cause fatalities, widespread damages and economic losses. Quite frequently, they are triggered by rainfall. Many studies have investigated the relationships between rainfall characteristics and landslide events. This paper revie…

Simulation of M2 Profiles in a Channel with Rigid Emergent Vegetation Open
The paper presents the results relying on 12 experimental M2 water profiles observed in a flume with emergent stems in a square arrangement. The authors used a recently proposed approach to determine the drag coefficients in the flow direc…

Simulation of Accelerated Subcritical Flow Profiles in an Open Channel with Emergent Rigid Vegetation Open
Even though both fluid mechanics and numerical studies have considerably progressed in the past decades, experimental knowledge remains an important tool for studying the resistance to flow in fluid media where a complex environment domina…

Effects of fluvial instability on the bed morphology in vegetated channels Open
Flume experiments are conducted to investigate the effect of streambed instability in channels with randomly-distributed vegetation, varying vegetation density and flow conditions, in the absence of upstream sediment supply. The bed morpho…

Flow Resistance in Open Channel Due to Vegetation at Reach Scale: A Review Open
Vegetation on the banks and flooding areas of watercourses significantly affects energy losses. To take the latter into account, computational models make use of resistance coefficients based on the evaluation of bed and walls roughness be…

Anisotropy in the Free Stream Region of Turbulent Flows through Emergent Rigid Vegetation on Rough Beds Open
Most of the existing works on vegetated flows are based on experimental tests in smooth channel beds with staggered-arranged rigid/flexible vegetation stems. Actually, a riverbed is characterized by other roughness elements, i.e., sediment…

Bed Roughness Effects on the Turbulence Characteristics of Flows through Emergent Rigid Vegetation Open
During floods, the riparian vegetation in a watercourse significantly changes the velocity distribution and the turbulence structures of the flow. However, a certain influence on them is always exerted by the bed sediments. The aim of the …

Discharge Coefficients for Sluice Gates Set in Weirs at Different Upstream Wall Inclinations Open
Laboratory experiments and numerical simulations are performed to measure discharge coefficients in the case of a gate located on the upstream wall of a weir for flood storage. The effect of the gate slope and the side contraction have bee…

Experimental and Numerical Study of Free-Surface Flows in a Corrugated Pipe Open
A new discharge computational model is proposed on the basis of the integration of the velocity profile across the flow cross-section in an internally corrugated pipe flowing partially full. The model takes into account the velocity profil…
