The effects of watershed treatments on the relationship between runoff peak and volume for the Beaver Creek watershed, ArizonaHawkins, Richard H.; Haddad, Munir Salim, 1953- (The University of Arizona., 1990)The relationship between runoff peak and volume was examined for ten sub-watersheds in the Beaver Creek, Arizona watershed. Least square analyses, linear regression, and coefficient analysis were utilized to evaluate the effects of treatments. Different treatments, such as clear cutting, uprooting, herbicide, and thinning, were applied on watersheds. For most of the watersheds, treatments were shown to have no significant effect on the relationship. However, herbicide treatment and clear cutting treatment in watersheds 3 and 12 respectively showed highly significant increases in peak flows. Significant increase in peak for the smaller events resulted from scattered patch cutting in watershed #10.
