    Description

    Comparisons based on pretreatment calibrations between summer flows and antecedent precipitation indices (APIs) at the Caspar Creek Experimental Watersheds show increased dry-season flow for 8 yr after selective logging, followed by at least 27 yr of depressed flow. In contrast, summer flow in a partially clearcut watershed remained higher than expected for 18 yr after logging. The API-based models were used to evaluate the effects of selected climate change scenarios when combined with logging-related hydrologic changes, with the effects assumed to act independently. Changes in rainfall late in the wet season have a disproportionate effect on dry-season flows, while autumn rains have little effect.
