*[[SMS:ADH Model Control | ADH Model Control]]


Layer 1 is the deepest (or bottom) layer; the highest numbered layer is exposed to the stream flow. The layer IDs cannot be edited and bed layering order is fixed to ascending layer ID order (See [[SMS:ADH Sediment Transport and Bed Layers|Sediment Transport and Bed Layers]]).


Edit spreadsheet column toolbar is enabled when a cell selection exists in the spreadsheet, and provides:
* Insert New Column Before tool inserts a single new bed layer column before (to the left of) the current selection.
* Delete Column(s) tool removes all of the bed layer columns of the currently selected cells.
Spreadsheet contains the defined bed layers as columns and bed layer specifications as rows. The bed layers begin with Layer 1 and proceeds by ascending order by ID to the right. This spreadsheet will be empty if no sediments have been defined on the Transport Constituents tab or zero bed layers are specified. The specification rows are as follows:
* Sediment distribution &ndash; Title cell with each defined sediment listed below in its own row. The row contains Normalize buttons for each bed layer. Clicking on the button will normalize the distribution of each sediment such that the total distribution equals 100%.
* Sediment (name) &ndash; Consists of this sediment's distribution (as a percentage) for each layer. A sediment row is provided for all defined sediments. The value must be a positive real number and correlates to the <font color="green">MP SBA</font> card.
* Total &ndash; Displays the current total specified distribution of all sediments for each layer. The row updates automatically as specifications change and cannot be edited. Each layer's total sediment distribution must equal 100%.
* Thickness &ndash; Consists of each bed layer's thickness measured in meters. The value must be a positive real number and correlates to the <font color="green">MP SBA</font> card.
* Bulk Density &ndash; Consists of each bed layer's bulk density measured in kilograms per cubic meter. This row only appears if a cohesive sediment (clay or silt) is defined. The value must be a positive non-zero real number and correlates to the <font color="green">MP CBA</font> card.
* Erosion crit. shear &ndash; Consists of each bed layer's critical shear stress for erosion measured in newtons per square meter. This row only appears if a cohesive sediment (clay or silt) is defined. The value must be a positive non-zero real number and correlates to the <font color="green">MP CBA</font> card.

* Erosion rate exponent &ndash; Consists of each bed layer's unitless erosion rate exponent. This row only appears if a cohesive sediment (clay or silt) is defined. The value must be a positive non-zero real number and correlates to the <font color="green">MP CBA</font> card.

Global Material Properties tab of the ADH Model Control dialog

Material properties for all materials can be specified in the ADH Model Control dialog (ADH | Model Control... command). It is accessed in the ADH Model Control dialog by clicking on the Global Material Properties tab.

ADH contains parameters that apply to all materials and parameters that are specific to (and must be defined for) each material. The parameters found within the Global Material Properties tab apply to all materials.

The bed layers specified here are applied to all mesh nodes and can only be overwritten at the nodal level in the Bed Layers Assignment window. When bed layers are created or deleted here, nodal bed layers are defaulted or deleted, respectively.

Parameters (Untitled Group Box)

Enable wetting/drying limits check box and the associated Dry depth and Wet depth positive real number edit fields correlate to the optional MP DTL card. If the water depth of a node is below the Dry depth, then the node is completely dry and is not included in the ADH shallow water equations. If the water depth is above the wet depth, then the node is included in the equations. A water depth which falls within these two depths will include the node in the equation with a restricting factor.

Constant

Uniform background viscosity positive real number edit field correlates to the MP MU card.

Gravitation acceleration positive real number edit field correlates to the MP G card.

Density positive real number edit field correlates to the MP RHO card.

Wetting and Drying

Enable shock capturing/stability procedures below depth is check box and the associated wetting and drying process. When this toggle is selected, ADH performs extra calculations for all cells with depth values less than the specified minimum to stabilize the process. As the specified depth value increases, extra calculations also increase and model performance decreases. When this option is selected, the Depth edit field is enabled by SMS. In this field specify a positive real number correlating to the optional MP DTL card.
