Fig. 3. Monthly observations of (A) precipitation, (B) runoff, (C) baseflow, and (D) total discharge from W1 between 1971 and 1995 (dotted lines). The annual and multi-year cyclic variations determined through autoregressive modeling (given in tables) are also plotted (heavy lines). For baseflow and total discharge, the full model with an autoregressive term is also plotted (thin line).
