Hydrograph Adjustment with Slope Exercise

two hydrographs changing with slope

Exercise Objective

To apply previous knowledge of river behavior to understanding impacts of river slope, measured in profile.

Exercise Process

  1. Examine the image showing the two hydrographs, which graphs of change in runoff with time in red and blue colors. Each hydrograph is a unitless sketch of runoff for the same precipitation event across the same watershed area. The hydrographs have the same total volume of runoff, but differ in timing and magnitude because of differences in the river slope.
  2. Try and determine which graph represents a river with steeper slope, and which represents a river with gentler slope.
  3. Once you have made your choice, advance to the next slide to find the key for the two colored lines.
