Analysis of the simulated scenarios

The total mass of sediment deposition over the season for all the developed scenarios was calculated from the simulations of the various hydro-morphodynamic models. Sediment deposition for different seasons was estimated using the total mass of sediment deposition over the representative 14 days of simulation and scaled for the total number of days in a season.
The trapping efficiency was calculated for all the scenarios to understand the effect of seasonality of SSC and different flow regime on the quantity of sediment delivered inside the beel and sediment retained. It was defined as the fraction of the incoming suspended sediment that is retained or deposited over the entire simulation period (Verschelling, van der Deijl, van der Perk, Sloff, & Middelkoop, 2017). Total incoming sediment load and sediment load retained were calculated using the water discharge and SSC at the inlets extracted from the model simulation. The difference between the incoming and outgoing sediment load at the inlets over the entire simulation period was considered as sediment load retained.
