The Wind Barrier Information (\textbf{Barriers} panel) (\cref{fig:WEPS_main_screen}) is used to add barriers to the field  borders.
Note that \WEPSver{} interface currently only allows barriers on the borders of the field, not within the field.
The barrier location is labeled for the side of the field on which the barrier is to be placed,
such as ‘N’ for north, ‘S’ for south, ‘E’ for east, and ‘W’ for west.
The \textbf{Field View} will automatically display the placement of selected barriers in red and highlight the currently selected location in yellow if no barrier exists there.
If there is already a barrier for the selected location, it will display with a mixture of both red and yellow stripes (\cref{fig:Wind_Barrier_Information_panel}).
Select a barrier location by selecting the appropriate radio button in the \textbf{Barriers} panel.
To "unselect" all barrier locations, click the currently enabled radio button
\img{images/icons/radiobutton.png}
to the off
\img{images/icons/buttonup.png}
position.
If the field is rotated, the location labels refer to the direction closest to one of the four cardinal directions.
To remove a barrier from the field, click the radio button
\img{images/icons/radiobutton.png}
to select it, then select the barrier type "none" to remove it.

The barrier type can be selected from the drop-down list in the panel by clicking the down arrow 
\img{images/icons/down_arrow.png}
box to the right of the barrier type to bring up the list of available barriers and clicking on the appropriate barrier.
Once a barrier type is selected, the barrier properties may be viewed and edited
by clicking the
\img{images/icons/Edit_Selected_Barrier_button}
button at the bottom of the panel
(\cref{fig:Wind_Barrier_Edit_window}).
This displays a separate panel where one may enter the barrier width, height, and porosity in the appropriate fields.
Note that the area of the barrier is displayed but cannot be edited.
If barrier properties have been modified, it will be noted in the barrier name list with a $\bf{<}$\bf{mod}$\bf{>}$ \normalfont
designation before the barrier name (\cref{fig:Wind_Barrier_Information_panel}).

See the \hl{“WEPS How To Guide” for Barriers} for further explanations on how to use barriers within WEPS and how to modify the barrier database.
Note that the \textbf{Barriers} panel is not the best way to simulate the effects of strip cropping,
but it may be useful in strip cropping designs that include barriers along the edge of the strips.
See the \hl{“WEPS How To Guide” for Strip Cropping} for a detailed description of simulating strip cropping with \WEPSver{}.
