Loading an FFMP Basin Trend Graph and Downstream Basin Trace

Purpose:

This task demonstrates how to launch an FFMP Basin Trend Graph from the FFMP Basin Table or the FFMP image display in the D-2D perspective.

Tasks:

Assumptions:

  • A FFMP Basin Table is loaded and the basins are displayed in the D-2D perspective.
  1. From the Layer menu in the FFMP Basin Table GUI, select All & Only Small Basins.
    • This will display the sub-basins for the entire domain.
  2. Loading a Basin Trend Graph can be accomplished using the following methods :
    1. Method 1: Right-click on one of the individual basins under the Name column in the FFMP Basin Table GUI .
    2. Method 2: Load a Basin Trend Graph from the FFMP Image in the D-2D perspective.
      1. From the Click menu in the FFMP Basin Table GUI, select Basin Trend.
      2. Switch over to your CAVE window with the D-2D perspective displaying the FFMP Table Display.
      3. In the Product Legend in the bottom-right corner of the display, middle-click the ffmp ktlx Table Display to make it editable.
      4. Right-click on a basin in the map editor.
        • First identify the instantaneous rate with the dark blue line. Any dots greater than zero indicate it rained at that time X hrs ago.
        • Notice the black line accumulates precip when the rate is above zero. Identify how much rain fell in the last 1 hr and last 3hrs.
        • Toggle on guid, and anywhere the black line accumulation is greater than the purple line is where FFG is being exceeded for that duration (e.g. look at -1.0 hrs and read off the QPE and FFG valid for a 1hr duration like QPE = 1.5” and FFG= 1.25” which would indicate FFG was exceeded for a 1hr duration by 0.25”).
  3. From the Click menu in the FFMP Basin Table GUI, select Downstream Basin Trace.
  4. Switch over to your CAVE window with the D-2D perspective displaying the FFMP Table Display.
  5. If the FFMP legend is not editable, middle-click on ffmp ktlx Table Display in the Product Legend.
  6. Right-click on a basin in the map editor.
    • Each basin downstream will show a connected path highlighting the downstream area.
    • To better see the basin trace you can right click on the FFMP legend text and select Change Up/Down Stream Color. Turning down the brightness using the Image Properties button or Ctrl + I can also help.
  7. Left-click on the Clear Trace button in the FFMP table to clear the downstream trace.
  8. Task Complete!
