QHEI Riffle/Run Metric

If best areas < 5cm or no riffle, metric scores a zero

Riffle/Run Characteristics What is depth of better

riffle and run areas? Measure depths in

areas that are clearly run or riffle

Are substrates coarse or fine?

Are substrates in riffle/run area embedded?

Calculating Stream Gradient:“Map Gradient”

Locate site on topo map

Find upstream and downstream contour line crossings

Calculate miles between contours

E.g. 640’ – 630’/1.5 miles = 6.67’/mile
