Reservoir sediments

[HIDAYA DAUD]

Hi, 

Can anyone knows here how to create a spatial and temproal distrubution of sediments in the reservoirs. What should I use from the acquired result in swatoutput. should i graph sed_inflow and sed_outflow and how to determine the sediments on it. I have 6 dams in my study area. thanks

Hello,

Sediments are considered uniformly distributed in reservoirs in SWAT+ (the routines are very simplistic), so there is no "spatial" attribute to it. To calculate the fluxes of sediments, you can indeed plot the sed_in and sed_out and the storage of sediment at any time point during your simulation.

Be advised that a sufficient initiation parametrization and warm-up period is required for the sediment budget in the waterbodies to come to a steady-state. 

All the best,

Natalja
