Gravity currents produced by full-depth lock-release of saline water into a fresh tank are studied focusing on the influence initial density mixture in lock and bed roughness gravity current kinematics.Temporal evolution front position velocity analysed related to different phases current.Time-space depth-averaged height assessed as well.Roughness channel plays an important role kinematics, particularly decreasing due extra drag at bed.The analysis Froude numbers, estimated with local...
An image analysis technique is used to estimate the two-dimensional instantaneous density field of unsteady gravity currents produced by full-depth lock-release saline water. experiment reproducing a current was performed in 3.0 m long, 0.20 wide and 0.30 deep Perspex flume with horizontal smooth bed recorded 25 Hz CCD video camera under controlled light conditions. Using dye concentration as tracer, calibration procedure established for each pixel relating amount uniformly distributed tank...

This laboratory study focused on the effect of a submerged vane-field flow pattern and bed morphology near inside entrance reach movable 90° lateral diversion. The system was modelled under live conditions for water discharge ratio ≈0.2. Two experiments were run until equilibrium reached: with without installed close to diversion control transfer sediments into channel. associated 3D field measured in great detail. load diverted reduced by approximately one quarter due action vane-field....
Water losses from water distribution means have a high environmental impact in terms of natural resource depletion (water, energy, ecosystems). This work aims to develop an optical airborne surveillance service for the detection leaks (WADI-Water-tightness Airborne Detection Implementation) provide utilities with adequate and timely information on transportation mains outside urban areas. Firstly, series measurement campaigns were performed two hyperspectral cameras thermal infrared camera...
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...

The interface between the main channel and floodplain of a compound is often populated by trees or buildings that normally remain emergent during floods. This study investigates how drag on an cylinder affected shear flow develops at interface. experimental set-up features circular straight under uniform conditions. integral form equation conservation momentum was used to calculate magnitude direction time-averaged force per unit submerged-length cylinder. All terms were experimentally...

The intended recording profiles variable shape sediment bottoms in hydraulics physical models. new instrument corresponds modern design classic one, better performance. New features include higher robustness and speed, improved power drive motor vertical motion control, as well microcontroller based unit x, y coordinate serial communication PC. has been used an experimental...
There are no studies specifically aimed at characterizing and quantifying drag forces on finite cylinder arrays in the mixing layer of compound channel flows. Addressing this research gap, current study is experimentally coefficients a square-cylinder array placed near main-channel/floodplain interface, where develops. Testing conditions comprise two values relative submergence floodplain similar ranges Froude bulk Reynolds numbers. Time-averaged hydrodynamic calculated from an integral...
