'''ADCIRC2D+''', is a mode which allows for the inclusion of baroclinic (density-driven) effects into the traditionally barotropic (depth-averaged) system. This is achieved by coupling ADCIRC with temperature and salinity fields from a coarser-resolution Ocean General Circulation Model (OGCM), enabling improved representation of long-term sea level dynamics. Description of results using this capability are available in (Pringle et al. 2019)<ref name="Pringle2019" /> and (Blakely et al. 2024)<ref name="Blakely2024" />

== Version ==
{{ADC version|version=56|relation=ge}}
Some of the capability of '''ADCIRC2D+''' is available in v55; however improvements and modifications were made that are present only in v56 and above.

== Governing Equations ==

ADCIRC2D+ solves a modified form of the shallow water equations using the Generalized Wave Continuity Equation (GWCE). The momentum equation includes baroclinic pressure gradient and [[Internal_Tide_Energy_Conversion|internal wave drag terms]]:
<math> \frac{\partial \mathbf{U}}{\partial t} + \mathbf{U} \cdot \nabla \mathbf{U} + f \mathbf{k} \times \mathbf{U} = - \nabla\left( \frac{p_s}{\rho_0} + g(\eta - \eta_{EQ} - \eta_{SAL}) \right) - \frac{\text{BPG}}{H} + \frac{\boldsymbol{\tau}_s - \boldsymbol{\tau}_b}{\rho_0 H} - \gamma_D \mathbf{C} \mathbf{U} </math>

Where:

*'''BPG''' is the depth-integrated baroclinic pressure gradient
*'''γD''' is a scaling parameter for internal wave drag
*'''C''' is the internal wave drag tensor

The baroclinic pressure gradient is computed as:
<math> \text{BPG} = \frac{g}{\rho_0} \left[ \int_{-h}^{0} \nabla \left( \int_{0}^{z} (\rho - \rho_0) \, dz' \right) dz + \eta \nabla[\eta(\rho_s - \rho_0)] \right] </math>

The internal tide drag tensor is scaled using a dissipation ratio <math>\gamma_D</math> defined by:
<math> \gamma_D = \frac{\text{Diss}_{\text{tidal}}}{\text{Diss}_{\text{total}}} = \frac{\mathbf{U}_{\text{tidal}} \cdot \mathbf{C} \cdot \mathbf{U}_{\text{tidal}}}{\mathbf{U} \cdot \mathbf{C} \cdot \mathbf{U}} </math>

Tidal velocity is estimated using a lagged 25-hour filter and removing the resultant mean signal from the total velocity. This ensures that dissipation from internal wave drag occurs predominantly at tidal frequencies, preserving tidal fidelity in the coupled model.

==<code>densityControl</code> Namelist==
Activating '''ADCIRC2D+''' is accomplished through the use of the <code>densityControl</code> namelist.This namelist has the following options and defaults (denoted by <code>(D)</code>)
*<code>densityRunType</code> (string)
::<code>'none' (D)</code>: By default '''ADCIRC2D+''' is not active. If <code>densityRunType='none'</code> the rest of the namelist values do not matter.
::<code>'prognostic'</code>
::<code>'diagnostic'</code>
*<code>densityFileName</code> (string): The name of the file from which pre-computed baroclinic pressure gradients and stratification information are read.
*<code>densityTimeIterator</code> (integer): The stride used when reading in <code>densityFileName</code>. For example, if <code>densityFileName</code> contains data at hourly timesteps and <code>densityTimeIterator=2</code> then data will be read in every two hours.
*<code>densityForcingType</code> (string)
::<code>'SigmaT'</code>
::<code>'Salinity'</code>
::<code>'Temperature'</code>
::<code>'SalinityTemperature'</code>
::<code>'Baroclinicgradients'</code>
::<code>'BaroclinicgradientsDispersion'</code>
::<code>'Buoyancyfrequencies'</code>
::<code>'BCForcingOnADCIRCGrid'</code>
::<code>'BuoyancyFrequenciesOnGrid'</code>

Within the ADCIRC code, the various settings of these namelist parameters is internally translated to an IDEN value which determines the baroclinic terms in the shallow water equations to include.

Fort.15 file format

2025-04-13T22:28:51Z

Cblakely: Adding densityControl namelist to list of namelists.

The basic file structure of the [[fort.15 file]] is shown below. Each line of input data is represented by a line containing the input variable name(s). Inputs in the [[fort.15 file]] must be entered in the exact order shown on this page. '''Blank lines and headings are only to enhance readability.''' Loops indicate multiple lines of input.
