Discharge

You can select the discharge calculation to be included for the flow and the AD state variables (state variables which are transported by the advection-dispersion). Each selected component will result in a number of output items.

You can select between two types of output items:

·         Basic

·         Extended

The basic output items are as follows:

·         Discharge - volume/energy/mass flux through the cross section

·         Acc. discharge - accumulated volume/energy/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.

For temperature the relative energy (relative to the energy at 0 ºC), E (J), in a volume of water V (m3) is calculated by

where T (ºC) is the temperature, cwater = 4217.0 J/(K.kg) is the specific heat for water and rwater = 1010.0 kg/m3 is the density of water.

For salinity the mass of salt, M (kg), in a volume of water V (m3)  is calculated by

where S (PSU) is the salinity and rwater = 1010.0 kg/m3 is the density of water.
