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.
