Webwhere i-ave is rainfall intensity measured in inches/hour and phi is an index of loss rate in similar units. The hydrologic “phi index” can be used to horizontally divide a hyetograph into direct runoff above and abstraction below. If no loss occurs, phi is 0.0 and C is 1.00. If loss is at the same rate as rainfall, C is 0.00.
