Study Layer Drawing Properties

When you select Properties for the Study layer, the Drawing Properties Editor appears ("Figure: Drawing Properties Editor - Reservoir Tab"). This editor has six tabs that allow you to view and edit properties of Reservoirs, Levees, Diversions, Channel Modifications, Computation Points, and Impact Areas in your watershed. The Study Layer is available only in the Layer Selector when opened from the Watershed Setup module.

Reservoirs

Reservoirs are drawn using four distinct elements:

• a Triangle Element—a re-shapeable polygon representing the reservoir pool,
• a Storage Reach Element—a thick line that follows the stream alignment and stretches from the inflow location(s) to the outflow location(s),
• a Dam Element—a rectangle drawn at the reservoir's outflow location(s), and
• a Reservoir Name label.

The Reservoir tab ("Figure: Drawing Properties Editor - Reservoir Tab") provides options for setting how reservoirs will appear in the Map Display. It is organized to present the drawing properties of each element of the reservoir separately.

The reservoir drawing properties you can modify include:

• Triangle Fill Color—select the fill color of the reservoir pool polygons from the list of pre-defined colors. The default fill color is cyan.
• Triangle Outline Color—select the color of the reservoir pool polygons outline from the list of pre-defined colors. The default line color is blue.
• Draw Reservoir Triangle—Use the checkbox to indicate if the reservoir pool polygons should be drawn in the Map Display area. Uncheck the box to turn OFF the reservoir pool polygons.
• Storage Reach Fill Color—select the fill color of the reservoir storage reaches from the list of pre-defined colors. The default fill color is cyan.
• Storage Reach Outline Color—Select the color of the outline of the reservoir storage reaches from the list of pre-defined colors. The default outline color is blue.
• Storage Reach Width—Select the width of the storage reaches, in points, from the selection list. Possible values are 1–10. The default width is 10.
• Dam Fill Color—Select the (fill and outline) color of the dam rectangles from the list of pre-defined colors. The default color is grey.
• Dam Width—Select the width of the dam rectangles, in points, from the selection list. Possible values are 1–10. The default width is 10. The length of the dam rectangle is a multiple of the width.
• Draw Reservoir Name—Use the checkbox to indicate if the reservoir name labels should be drawn in the Map Display. Uncheck the box to turn OFF the reservoir names.

• Font…—This button opens the Font Chooser ("Figure: Font Chooser"). Use it to select the Font and Size of the name label and whether it should be Bold and/or Italic. You can even change the Sample Text used to preview your selections. Click OK to save your settings and close the Font Chooser. The reservoir names will be drawn using the Triangle Outline Color.

Levees

Levees are drawn as a line that parallels the stream alignment. The Levees tab ("Figure: Drawing Properties Editor - Levees Tab") provides options for setting the drawing properties of that line and its label.

The levee drawing properties you can modify include:

• Levee Line Color—Select the color of the diversion line from the list of pre-defined colors. The default levee line color is black.
• Levee Width—Select the diversion line width, in points, from the selection list. Possible values are 1–10. The default width is 8.
• Draw Levee Name state—Use the checkbox to indicate if the name labels should be drawn with the levees in the Map Display area. Uncheck the box to turn OFF the levee names.
• Font…—This button opens the Font Chooser ("Figure: Font Chooser"). Use it to modify the font properties for the levee name labels. The levee names will be drawn using the Levee Line Color.

Diversions

A diversion is drawn as a polyline with an arrowhead at the downstream end. The connectivity of the downstream end of a diversion is reflected in the color of the arrowhead.

The Diversions tab ("Figure: Drawing Properties Editor - Diversions Tab"), provides options for setting how diversions will appear in the Map Display area. The diversion drawing properties are presented in three sections—the Line Element, the Arrowhead Element, and the Name label.

The diversion drawing properties you can modify include:

• Diversion Line Color—select the color of the diversion line from the list of pre-defined colors. The default diversion line color is black.
• Diversion Line Width—select the line width, in points, from the selection list. Possible values are 1–10. The default diversion line width is 5.
• Diversion Arrowhead Color - Connected—This is the fill color of the arrowhead when the diversion is connected to a computation point at the downstream end. Select the color from the list of pre-defined colors. The default fill color is blue. The outline color of the arrowhead is always black.
• Diversion Arrowhead Color - Disconnected—This is the fill color of the arrowhead when the diversion is not connected to anything at its downstream end. Select the color from the list of pre-defined colors. The default fill color is black. The outline color of the arrowhead is always black.
• Draw Diversion Name—Use the checkbox to indicate if the name labels should be drawn with the diversions in the Map Display area. Uncheck the box to turn OFF the diversion names.
• Font…—This button opens the Font Chooser (Figure: Font Chooser). Use it to modify the font properties for the diversion names. The diversion names will be drawn using the Diversion Line Color.

Channel Modifications

A channel modification is drawn as a thick line on top of the stream alignment. The Channel Modification tab ("Figure: Drawing Properties Editor - Channel Modification Tab") provides options for setting how channel modifications will appear in the Map Display area.

The channel modification drawing properties you can modify include:

• Channel Modification Line Color—Select the color of the line drawn on top of the stream alignment from the selection list. The default color is black.
• Channel Modification Width—Select the line width, in points, from the selection list. Possible values are 1–10; the default is 10.
• Draw Channel Modification Name—Use the checkbox to indicate if the name labels should be drawn with the channel modifications in the Map Display area. Uncheck the box to turn OFF the channel modification names.
• Font…—This button opens the Font Chooser (Figure: Font Chooser). Use it to modify the font properties for the channel modification name labels. The channel modification names will be drawn using the Channel Modification Line Color.

Computation Points

The Computation Point tab ("Figure: Drawing Properties Editor - Computation Point Tab") of the Drawing Properties Editor provides options for setting the computation point drawing properties, however only modifications to the Computation Point Name properties will actually impact what you see in the Map Display.

The rest of the drawing properties for the computation point elements in the Map Display are managed by the Computation Point Layer Editor.

To open the Computation Point Layer Editor:

• Select Computation Point Layers from the Edit menu of the Watershed Setup module.

The Computation Point Layer Editor allows you to create computation point layers and set the drawing properties per layer. Every watershed is created with a default computation point layer—called Default. In ResSim watersheds, this is really all you need since ResSim cannot take advantage of additional computation point layers.

The computation point drawing properties available in the Computation Point Layer Editor ("Figure: Computation Point Layer Editor") include the Computation Point's:

• Background Color—the outline of the symbol...
• Foreground Color—the fill color of the symbol...
• Symbol—the shape or text character used to represent the computation point on the map schematic.
• Symbol Size—a value, in points, between 4 and 25. A value of 10 is approximately equal to the size of a 10pt font.

See the HEC-WAT User's Manual for more details on Computation Point layers.|

The computation point name drawing properties you can modify from the Drawing Properties Editor include:

• Draw Computation Point Name—Use the checkbox to turn ON or OFF drawing of the computation point name labels in the Map Display.
• Font…—This button opens the Font Chooser ("Figure: Font Chooser"). Use it to modify the font properties for the computation point name labels. The computation point names will be drawn in black.

Impact Areas

The Impact Area tab ("Figure: Drawing Properties Editor - Impact Area Tab") provides options for modifying the Impact Area Name label properties. They include:

• Draw Impact Area Name—Use the checkbox to indicate if the name labels should be drawn with the impact areas in the Map Display. Uncheck the box to turn OFF the impact area names.

• Font…—This button opens the Font Chooser ("Figure: Font Chooser"). Use it to modify the font properties for the impact area name labels. The impact area names will be drawn in black.
