Abstract

The relationship between rainfall and runoff was examined for twelve selected Arizona watersheds. Expedient runoff volume model coefficients and runoff curve number model parameters were examined using standardized structure, with modifications to adjust the model for small initial abstractions and large watershed storage capacity.

Forest-land management practices were examined for their effects on curve number coefficients. The effects of rainfall characteristics were also evaluated with respect to changes they induce in curve number populations.

Evaluations included a runoff fraction, a simple multiplier of storm volume to produce runoff volume. The accuracy of this model is promising for more permeable watersheds.
