Experimental investigation of fine sediment deposition using particle image velocimetry

A Comprehensive Review on Sediment Transport, Flow Dynamics, and Hazards in Steep Channels

“…These require specific modeling approaches, effective management strategies, and conservation efforts in dynamic and challenging terrains. However, these processes have been studied experimentally and analytically (Bombar et al 2011;MoayeriKashani et al 2017;Singh and Ahmad 2019). Bombar et al (2011) conducted experiments on unsteady sediment transport in a laboratory flume by introducing sedimentograph feedings to the setup.…”

“…Moreover, qualitative investigations were also conducted using unsteady-flow parameters and the total flow work index. MoayeriKashani et al (2017) carried out an experimental study by investigating fine sediments through particle image velocimetry. They demonstrated that gravitational forces on the sediments increases by over 50 percent at the greater depths and the optimal sediment collection efficiency at the water surface was observed to be approximately 80 percent.…”

“…The studies discussed above by Bombar et al (2011), MoayeriKashani et al (2017, Singh and Ahmad (2019), Singh and Tayfur (2008), Singh (2012), Fiengo Pérez et al (2017), Chalov et al (2015), Qian et al (2015), and Zhao et al (2019), have significantly advanced our understanding of sediment transport in mountain streams. However, it is crucial to acknowledge certain limitations and drawbacks in these investigations.…”

Age of Water Particles as a Diagnosis of Steady-State Flows in Shallow Rectangular Reservoirs

“…Shallow reservoirs are common hydraulic structures. They are used as storm water retention or treatment ponds [1][2][3][4][5][6][7], sedimentation tanks [8][9][10] or service reservoirs [11]. They are also of use in aquaculture [12].…”

“…The operational performance of shallow reservoirs is strongly affected by the type of flow pattern, because the flow field has a direct influence on the reservoir sediment trapping efficiency [4], on the spatial distribution of sediment deposits [8,23], on pollutant removal efficiency [1], and on the disinfection efficiency in service reservoirs [11]. Accurately predicting the flow field in shallow reservoirs is therefore of high engineering relevance for guiding their optimal design, sizing and management.…”
