Discharge

When you have selected “Pure current” for the model type and “Non equilib­rium” for the transport description, you can select the discharge calculation to be included for the flow and for the suspended sediment load.
The discharge of the suspended sediment load is calculated using the gen­eral transport equations and does NOT consider the Speedup factor.

When you have selected “Wave and current” for the model type, you can select the discharge calculation to be included for the flow and the total sedi­ment load.
The discharge of the total sediment load is calculated based on the recon­structed fluxes and INCLUDES the effect of the Speedup factor. The values may be affected by the maximum limit of bed level change.

You can select between two types of output items:

·         Basic

·         Extended

The basic output items are as follows:

·         Discharge - volume/mass flux through the cross section

·         Acc. discharge - accumulated volume/mass flux through the cross sec­tion

The extended output items that are included in the output file in addition to the basic output items are as follows:

·         Positive discharge

·         Accumulated positive discharge

·         Negative discharge

·         Accumulated negative discharge

By definition, discharge is positive for flow towards left when positioned at the first point and looking forward along the cross-section line. The transports are always integrated over the entire water depth. The discharge rates are given in solid volumes.

NOTE: output of discharge is not available in the case of equilibrium pure cur­rent.
