# Salt Data Fields

## Data Input

In order to input the required information for this pollutant into the Water Quality model, the user needs to make sure that the Tab Salt appears in the WQ General Tab (please follow the description on the page [Preparing a Water Quality Datafile](/v1/docs/preparing-a-water-quality-datafile) for this). Then the user needs to select the Tab Salt and type in the necessary information for this pollutant in the fields which are shown on this Tab. Alternatively the necessary information for this pollutant can be typed in the .con file opened in a Textpad editor in the datafile format mentioned below.

## Datafile Format

*If a constant salinity value is to be simulated use:*

Line 1 SALT

Line 2 CONSTANT

Line 3 salt

Where:

SALT = keyword

CONSTANT = keyword

salt = Value of constant salinity imposed over whole model (ppt).

*If variable salinity is to be modelled then use:*

Line 1 SALT

Line 2 VARIABLE

Where:

SALT = keyword

VARIABLE = keyword
