| Abstract |
Principal component analysis using varimax rotation of components was used to develop daily streamflow prediction equations, using existing streamflow and precipitation records. Analyses were primarily confined to river basins receiving maximum amounts of total precipitation as rainfall. A few analyses used rivers with large winter snow pack accumulations. Reduced accurary of prediction equations was found when snowmelt is the main source of streamflow. Interpretation of the variation in prediction equations over time confirmed the theoretical considerations that forest land management does influence the hydrologic regime of river basins.
