{{Current development}}
The Arc Properties dialog is where the parameters for an arc in a Boundary Conditions or Hydrograph coverage are defined. Only one type of boundary condition can be assigned to a feature object on a Boundary Conditions coverage. For Hydrograph coverages, "Hydrograph" is the only option available to assign to a feature object.

==Head or Flux, Boundary Conditions Coverage==
Head and Flux are two separate available arc property types, but the input options available are the same. Those input options are listed below.
*Name
*Domain: Porous media; the domain in which the boundary condition is applied.
**Minimum sheet: boundary conditions will be applied between the minimum and maximum node sheets.
**Maximum sheet: boundary conditions will be applied between the minimum and maximum node sheets.
**Input type: how the boundary condition data is specified.
***Constant
****Constant (start): constant value of the boundary condition at the start of the arc.
****Constant (end):  constant value of the boundary condition at the end of the arc.
***Time series
****Time series (start): time-varying values of the boundary condition at the start of the arc.
****Time series (end): time-varying values of the boundary condition at the end of the arc.
****Interpolate: causes time-varying values to be interpolated, resulting in a smoother application of the time-varying function.
****Map to grid boundary: map boundary condition to the boundary of the grid (not the interior).
*Domain: Surface flow; the domain in which the boundary condition is applied.
**Input type: how the boundary condition data is specified.
***Constant 
****Constant (start): constant value of the boundary condition at the start of the arc.
****Constant (end):  constant value of the boundary condition at the end of the arc.
****Map to grid boundary: map boundary condition to the boundary of the grid (not the interior).
***Time series
****Time series (start): time-varying values of the boundary condition at the start of the arc.
****Time series (end): time-varying values of the boundary condition at the end of the arc.
****Interpolate: causes time-varying values to be interpolated, resulting in a smoother application of the time-varying function.
****Map to grid boundary: map boundary condition to the boundary of the grid (not the interior).

==Simple River or Simple Drain, Boundary Conditions Coverage==
Simple river and Simple are two separate available arc property types, but the input options available are the same. Those input options are listed below.
*Name
**Input type: how the boundary condition data is specified.
***Constant
****Constant (start): constant value of the boundary condition at the start of the arc.
****Constant (end):  constant value of the boundary condition at the end of the arc.
***Map to grid boundary: map boundary condition to the boundary of the grid (not the interior).
***Time series
****Time series (start): time-varying values of the boundary condition at the start of the arc.
****Time series (end): time-varying values of the boundary condition at the end of the arc.
****Interpolate: causes time-varying values to be interpolated, resulting in a smoother application of the time-varying function.
****Map to grid boundary: map boundary condition to the boundary of the grid (not the interior).

==Critical Depth, Boundary Conditions Coverage==
*Name
***Transient: option to define a time value table to turn the boundary condition on and off. Values of -99999 indicate that the BC is turned off.
****Time series: Time value table. Values of -99999 indicate that the BC is turned off.
***Map to grid boundary: map boundary condition to the boundary of the grid (not the interior).

==Hydrograph, Hydrograph Coverage==
*Name: a descriptive name for the hydrograph, which can be up to 80 characters.
*Map to grid boundary: map grid to the boundary of the grid, not the interior.
