Click the Run bottom at the bottom of the hillslope or watershed picture. Brief output is displayed in the grid to see more detailed output click on the ”Text Output” or “Graphics Output” buttons. To see what outputs the WEPP model is configured to produce click on the “Run Options” button check or uncheck the output files you want to see (the simulation will have to be run again to produce the output files). The simulation will run for the number of years indicated above the output grid.
The WEPP model will run the fastest if the fewest number of options are selected in the Run Options. Click the “Run Options” button to select what output files to produce. The number of different management sections and soil sections on the hillslope also effects how fast a simulation is done, again less sections produce faster simulation times.
Climate file can be interchanged between the two interfaces. The other files are not compatible. In the future the Windows interface will have an import tool to read DOS hillslope projects.
The WEPP model
only supports setting up 10 distinct soil and management sections, trying to add
more will display an error.The
colors for the shading in the watershed or hillslope are “blocky”?
This is probably due to the color setting being used for your display. To get the best shading Windows should be set to use “High Color” or “True Color”. A color setting of 256 colors does not show all the shading. The color setting can be changed by right clicking on the Windows desktop and then selecting properties and then the “Settings” tab and selecting an item from the Colors list.
Click the toolbar button with the E/M this toggles the units on the main screen and also causes other windows that are opened to default to that units setting.
With the mouse cursor hovering over the border between the grid and the main hillslope graphic the cursor should change to a vertical arrow. Click and hold down the left mouse button and drag the boundary to a new location. The position of the boundary is not saved when the project is closed; it is always initialized to a default position when the project is opened.
There are two ways to change the slope length. To preserve the current shape proportions select the middle layer of the hillslope graphic by clicking on it with the right mouse button and picking the “change length” menu item. Type in the new length in the dialog and click OK. To make other changes to the slope double click on the slope layer to display the slope profile editor. Changing the steepness or segment lengths of the sections will cause the slope length to change. When the changes are saved in the slope profile editor they will be reflected on the main display.
There are two ways to change the length of a management section. Move the mouse cursor over the desired section and then right-click to display a menu, select the “change length” menu item. Type in the new length in the dialog and click OK. Another (less precise) method is to move the cursor over a dividing line between management sections; the shape will change to a horizontal arrow. Clicking and holding the left mouse button while dragging the dividing line will reposition it, releasing the left mouse button completes the move.
There are two ways to add a management section. In both
cases a “break” dividing line must be inserted where you want the new field
boundary. The new management section initially has the same management as the
section where the break was inserted. A break can be inserted by hovering the
mouse over the location on the management layer where you want the boundary and
then right click and select “insert break” from the menu. Alternatively
select the break icon (black triangle) from the toolbar which causes the cursor
to change shape and enter break insert mode. Any place you left click on the
management layer inserts a break after answering yes to the popup window. To
exit break mode left click anyplace on the background or click the break icon
again (the cursor will return to an arrow shape).Delete
a management section?
To delete a management section right click while over the section and then select the delete item, Choose OK when asked to confirm the operation.
There are two ways to change the length of a soil section. Move the mouse cursor over the desired section and then right-click to display a menu, select the “change length” menu item. Type in the new length in the dialog and click OK. Another (less precise) method is to move the cursor over a dividing line between soil sections; the shape will change to a horizontal arrow. Clicking and holding the left mouse button while dragging the dividing line will reposition it, releasing the left mouse button completes the move.
There are two ways to add a soil section. In both cases a “break” dividing line must be inserted where you want the new soil boundary. The new soil section initially has the same soil as the section where the break was inserted. A break can be inserted by hovering the mouse over the location on the soil layer where you want the boundary and then right click and select “insert break” from the menu. Alternatively select the break icon (black triangle) from the toolbar which causes the cursor to change shape and enter break insert mode. Any place you left click on the soil layer inserts a break after answering yes to the popup window. To exit break mode left click anyplace on the background or click the break icon again (the cursor will return to an arrow shape).
To delete a soil section right click while over the section and then select the delete item, Choose Yes when asked to confirm the operation. The delete icon on the toolbar (X icon) can also be used, first left-click on the section to delete to select it (section will have diagonal lines when selected) then click the delete icon on the toolbar and finally choose yes when asked to confirm the operation.
To change to a different soil right-click on the section to change and choose Import. The soil import list window will be displayed, double click on the soil to be used. To change the properties of a soil double-click on the soil section to change to display the soil editor, change any fields and click “Save”.
To change to a different management right-click on the section to change and choose Import. The management import list window will be displayed, double click on the management to be used. To change the details of a management section or create a new management double-click on the management section to change to display the management editor, change any fields and click “Save”.
A new project can be created by making changes to an existing project and then choosing File and then Save As to give the project a new name.
To change the climate used in a simulation an existing climate can be imported by right-clicking on the climate icon (the sun in the upper left corner) and selecting the import menu item. The climate import list window will be displayed, double click on the climate to be used. To change the details of a climate or create a new climate file double-click on the climate icon to display the climate editor, change any fields and click “Save” or “Save As”(to create a new climate file).
The number of years used in the simulation is determined by the number of years selected in the run options. Click the Run Options button and adjust the number of years to simulate. The length of simulation can not be longer than the number of years of climate data available. Attempting to run a project for more years than there is available data will display a warning message indicating the simulation will stop at the end of the climate data and not run for the number of years the user has requested.
This text is displayed on the 3D view of a hillslope. Double click on the management section to change to display the management editor and type in a new description at the bottom and click “save”.
From the File menu choose the Print or Print Preview menu items.
Move the mouse over the graph and then right-click to display a menu of options. Choose “Export”, in the export window select Metafile and Printer options. You can also save the graph so that it can imported into other programs by saving to a file or the clipboard.
Results can be copied to any program that uses the Windows clipboard. From the Edit menu choose “Copy Results” after running a simulation. In the other program (such as Notepad, Excel, Word) select Paste to import the text.
The WEPP model can produce 91 daily output values in the graphics file. To limit the number of variables the user can choose from click on the “Customize” toolbar button (checkmark icon) and select the Graphics tab. Indicate which variables to display by putting a checkmark next to the name. Click “Apply” to record the changes. The next the graphics output window is displayed only those variables selected will be displayed.
