Efficient reservoir management is essential for ensuring water security and flood control, as well hydroelectric power generation. Accurate volume measurements are key to optimizing these functions, but traditional methods—such in situ physical surveys—are often time-consuming, costly, unfeasible many regions due financial or geographical limitations. This study introduces a novel globally accessible remote sensing tool designed overcome challenges by providing more effective approach...
Abstract Turbulent mixing layers associated with streamwise uniform and nonuniform flows in compound channels (main channel adjacent floodplains) are experimentally investigated. The experiments start flow conditions. nonuniformity is then generated by imposing an imbalance the upstream discharge distribution between main (MC) floodplains (FPs), keeping total constant, which results a transverse depth‐averaged mean flow. This study first aims at assessing effect of on layer coherent...
The reported experimental study assesses the effects of flow non-uniformity on momentum flux in straight compound channels. Two flumes were used, featuring vertical and sloping banks. Starting with uniform condition, various imbalances upstream discharge distribution introduced. This resulted a time-averaged lateral advective transport momentum, which interacted shear-layer turbulence generated by geometry. To investigate this interaction, three contributions to transverse (depth-averaged...
River confluences are dynamic zones where hydrodynamic interactions between tributary flows—varying in velocity, direction, and sediment concentration—can significantly alter hydro morphology. These changes feature substantial consequences for the stability of riverbanks, nearby hydraulic structures, surrounding environment. This paper investigates flow mechanisms dynamics a symmetric 50° confluence through laboratory experiments on scaled physical model real located Madeira Island,...

Abstract The presence of vegetation on the floodplains compound channels affects structure mean flow, increases flow resistance and turbulence intensity, impacts sediment transport. In prismatic channels, shear stress at interface between flows in main channel lateral has a strong influence cross sectional velocity distribution thus conveyance channel. Due to mass transfer subsections, these effects are enhanced non‐prismatic channels. present study, three‐dimensional turbulent vegetated...
Abstract Connecting storm-sewers located at rather different elevations may be made with vortex drop shafts in which the energy dissipation is by friction between vertical shaft and flow downstream impinging jet a chamber. Following first model design 1940s, types of have been developed. One most used type so-called spiral developed to work supercritical good performance both space constrains. In this paper, an experimental characterization conducted covering three main components these...
The present study aims at understanding the changes in channel conveyance and turbulent flow structure due to presence of both submerged vegetation floodplains riparian vegetation. An experimental campaign was carried out comprising uniform compound channels flows (i) without any kind vegetation, (ii) with synthetic grass floodplains, (iii) rods interface between main floodplain (iv) artificial shrubs floodplain. For comparison, water depth all cases kept constant. Accurate acoustic Doppler...

Flood hazards (flow depth and velocity) must be accurately assessed in high-risk areas during extreme flood events. However, the prediction of very high flows is not an easy task due to lack field data strong link between flow resistance land occupation floodplain. Confinement inhomogeneity lateral longitudinal directions hydraulic roughness strongly vary with return period T. The physical processes are complex, some still largely unexplored, assumptions linked numerical modelling cannot...
River channel confluences are rather important interfaces where intense changes in physical, mixing and sediment transport processes occur. Following an experimental campaign, the main flow mechanisms development of shear layer formed between two tributary flows presented. As cases comprised discharge widths tributaries, influence width ratios on turbulent structure is also evaluated. Main findings indicate that difference momentum ratio tributaries have a significant effect magnitude...
Abstract Overbank flows occur in alluvial valleys during flood events when the conveyance of main channel rivers is exceeded. Once floodplains are inundated and so-called compound flow observed, faster interacts with slower floodplain featuring a much more pronounced 3D structure compared to single flow. These mechanisms comprise shear layer near interface, lateral momentum transfer strong secondary currents due non-isotropic turbulence. This paper starts by giving an overview channels...
