“…Two positions must be taught: the first Teach-in position aligns with 0 V (or 4 mA), the second position aligns with 10 V (or 20 mA), therefore the current or voltage output adapts to the new range [5]. Finally, based on the characteristic calibration line of the laser, the output voltage can be linked to the distance of the laser light source to the top of the sediment deposit and consequently, the thickness of the deposit can be calculated [7].…”

“…Shallow flows are predominant in nature and also emerge in many engineering applications such as sudden expansions (Shapira et al, 1990), compound channels (Chu et al, 1991;Ghidaoui and Kolyshkin, 1999), storage chambers (Adamson et al, 2003;Stovin and Saul, 1996), settling tanks (Frey et al, 1993), shallow reservoirs sedimentation (Camnasio et al, 2013;Dufresne et al, 2012;Kantoush et al, 2008aKantoush et al, , 2010 and sediment flushing (Esmaeili et al, 2014b;Kantoush and Schleiss, 2009). …”

2 3 4 5Shallow flows can play a significant role in sediment management for dam reservoirs (e.g. sedimentation in shallow reservoirs and free-flow flushing operation). When shallow flow emerges with symmetric or asymmetric patterns, the flow domain exhibits complex three-dimensional (3D) features (e.g. helical flows). This study focuses on the numerical modelling of the velocity field in shallow reservoirs with varying geometries and also varying bed conditions (i.e. flat and misshaped beds). A fully 3D numerical model using the finite-volume method was utilised to reproduce the 3D flow velocity field. The experimentally measured surface velocity in all cases and velocity profiles in one case were used to validate the model. The numerical results showed that a slight disturbance in the inflow boundary condition results in a steady asymmetric flow pattern in reservoirs with a higher defined shape factor, but does not affect the flow pattern in reservoirs with a lower defined shape factor. Nonetheless, the simulated and measured flow velocity fields are reasonably consistent in all cases. These results can be used to optimise the design of sand traps or water storage facilities, and also to optimise sediment management in existing reservoirs.

“…The model was extensively validated for inundation modelling along over 1300 km of rivers (Erpicum et al, 2010a, b), as well as for other complex turbulent flow (Camnasio et al, 2013;Dewals et al, 2008;Erpicum et al, 2009;Roger et al, 2009). It provides detailed spatially distributed results throughout the floodplains (Beckers et al, 2013;Dewals et al, 2011;Ernst et al, 2010).…”

Abstract. According to available climate change scenarios for Belgium, drier summers and wetter winters are expected. In this study, we focus on two multi-purpose reservoirs located in the Vesdre catchment, which is part of the Meuse basin. The current operation rules of the reservoirs are first analysed. Next, the impacts of two climate change scenarios are assessed and enhanced operation rules are proposed to mitigate these impacts. For this purpose, an integrated model of the catchment was used. It includes a hydrological model, one-dimensional and two-dimensional hydraulic models of the river and its main tributaries, a model of the reservoir system and a flood damage model. Five performance indicators of the reservoir system have been defined, reflecting its ability to provide sufficient drinking water, to control floods, to produce hydropower and to reduce low-flow conditions. As shown by the results, enhanced operation rules may improve the drinking water potential and the low-flow augmentation while the existing operation rules are efficient for flood control and for hydropower production.
