Ouachita River Reach Pattern Exercise

Ouachita section

Exercise Objective

To apply Rosgen Level II pattern analysis and determine various FGM characteristics on the single threaded Ouachita River reach.

Exercise Process

  1. Obtain a high resolution map of the picture shown on this page by right clicking on the image with your mouse to Save Target As … on your computer. Note the Ouachita River reach of interest between points A and B on this map.
  2. View the high resolution map 06_54_01a.jpg in ImageJ and determine pattern FGM properties. In Level II, morphological parameters measured using the channel pattern data are often confirmed and refined by in-field measurements.
  3. Measure the following:
    • Reach length between points A and B
    • Valley length between points A and B
  4. Please save your measurements for future application in this exercise.
  5. Compute the following. To make this calculation, you may need to refer to earlier instruction in FGM Module Section 3.
    • Sinuosity.
