== General Description ==

The Basic Pond model is used in the Dynamic mode to emulate an Evaporation Pond. The user has the option to divide the pond into two layers, a bed where most of the solids settle and a clarified liquor layer for liquids, or consider the pond as a single layer.  In any case, the concentration of the pore liquid in the bed layer and the concentration of the supernatant pond liquid is always equal and in equilibrium with the solids.

== Data Sections ==
# '''[[#BasicPond tab page|BasicPond]]''' tab - The first tab contains general information relating to the unit and allows the user to configure the unit.
# '''[[#Outlets tab page|Outlets]]''' tab - Optional tab, only visible if one of the optional slurry outlets are connected (CL_Out, Bed_Out or Seepage). This tab allows user to configure the various outputs from the pond as defined in the list of outputs above.
# '''[[#Results tab page|Results]]''' tab - Contains results of the model including summary of content parameters.
# '''[[RB|CRB]]''' - Optional tab, only visible if '''Rxns.Option''' = ''CRB''.
# '''[[MU]]''' - Optional tab, or multiple tabs if more than 1 Makeup is selected.  Only visible if one of more Makeups are enabled in the Evaluation Block on the first tab page.
# '''[[Material Flow Section|QFeed]]''' - Optional tab, only visible if ''ShowQFeed'' is enabled on the first tab page. This page shows the properties of the mixed stream as the feed to the unit.  If user has specified a required pressure in the unit, the mixed feed will be set to this pressure. This may cause the temperature of the mixture to change if the delta P is significantly different.
# '''[[Material Content Section|Bed]]''' tab - Optional tab, only visible if ''BedLayer.Partition'' and ''ShowBed'' are enabled on the first tab page. Contains data on the material in the bed.
# '''[[Material Content Section|CL]]''' tab - Optional tab, only visible if ''BedLayer.Partition'' and ''ShowCL'' are enabled on the first tab page. Contains data on the material in the clarified liquor layer.
# '''[[Material Content Section|Content]]''' tab - contains data on the material in the pond.
# '''[[#Preset tab page|Preset]]''' tab - Optional tab, only visible if ''UsePreset'' option is enabled on the first tab page. Allows user to define the Preset composition.
# '''[[Material Flow Section|QCL]]''' - Optional tab, only visible if the '''CL_Out''' outlet is connected and ''ShowQCL'' is enabled on the first tab page. This page shows the properties of the CL_Out stream.
# '''[[Material Flow Section|QBed]]''' - Optional tab, only visible if the '''Bed_Out''' outlet is connected and ''ShowQBed'' is enabled on the first tab page. This page shows the properties of the Bed_Out stream.
# '''[[Common Data Sections#Common Data on Info Tab Page|Info]]''' tab - contains general settings for the unit and allows the user to include documentation about the unit and create Hyperlinks to external documents.
# '''[[Links Table|Links]]''' tab, contains a summary table for all the input and output streams. 
# '''[[Audit]]''' tab - contains summary information required for Mass and Energy balance. See [[Model Examples]] for enthalpy calculation Examples.

=== BasicPond tab page ===

{{TCEPond Tab Page|TCE =Basic}}

=== Outlets tab page ===

{{Pond Outlets Tab}}

=== Results tab page ===

{{Pond Results Tab|HideTCE=Yes}}

=== Preset tab page ===

The Preset page contains a ''Copy to Clipboard'' button which copies the current temperature, pressure and composition of the Preset to the clipboard for pasting into external programs such as Excel.

This page is used to set the required composition of the Pond when it is Preset. This is identical in functionality to the [[Define Species (DSp) Section|DSp]] page used in Feeders.
