Numerical modelling of bed load sediment traps in sewer systems by density currents
TLDR
In this paper, a model with density currents has been developed and tested to simulate bed load sediment traps, where the bed load layer over the pipe invert is considered as a continuous layer characterised by a density and a viscosity which depends on the solid concentration.About:

Comparison of two- and three-dimensional modeling of invert trap for sewer solid management
Tsewang Thinglas,Deo Raj Kaushal +1 more
TL;DR: In this paper, five different invert trap configurations (rectangular with and without lids on both sides; trapezoidal, trapezoid with rectangular base and rectangular with trapezoids base with lids in both sides) were simulated for both 2D and 3D flow conditions for three sediment types (sand, styrocell and plastic beads).

Three-Dimensional CFD Modeling for Optimization of Invert Trap Configuration to Be Used in Sewer Solids Management
T. Thinglas,Deo Raj Kaushal +1 more
TL;DR: In this paper, five different invert trap configurations have been simulated for the flow of three different inert sediment types (sand, styrocell, and plastic beads) at six flow rates (0.35, 0.70, 1.05, 1,05 and 1.95 Lps) for each trap.

3D CFD validation of invert trap efficiency for sewer solid management using VOF model
Mohammad Mohsin,Deo Raj Kaushal +1 more
TL;DR: In this paper, a 3D computational fluid dynamics (CFD) model with the volume of fluid (VOF) model, along with stochastic DPM, was used to model the trap efficiency of an invert trap fitted in an open rectangular channel.

Particle-driven gravity currents.
TL;DR: In this paper, the dynamics of the current are assumed to be dominated by a balance between inertial and buoyancy forces; viscous forces are assumed negligible, and the particle concentration is derived by assuming that the particles are vertically well-mixed by the turbulence in the current, are advected by the mean flow and settle out through the viscous sublayer at the bottom of a current.

Technical solutions envisaged in managing solids in combined sewer networks
TL;DR: In this paper, the authors discuss the partial extraction of the largest solids and selective trapping of bed load solids, which form deposits; and the displacement of deposits using dry weather flow flushing waves.

Two experimental sediment traps: operation and solids characteristics
TL;DR: In this paper, two field experiments have been carried out in Bordeaux (south-west of France) in 1993 and 1994 to characterise the solids caught in the traps and to assess the sediment trap efficiency.
