A Prediction Equation for Vegetation Effects on Water Yield from Watersheds in Arid Areas
1970
Grover, B. L. | Campbell, C. B. | Campbell, M. D.
A water yield prediction equation based on plant type, water use profiles, and historic precipitation records is presented. The equation can be set at any desired probability value. Yields predicted for sites occupied by deep-rooted brush species average 14 cm less per year than those for sites occupied by a grass-forb complex. This pattern holds for central Utah watersheds higher than 2,330 m above mean sea level in 4 out of 5 years.
