Fig. 4. Cumulative Cl– vs. cumulative water plots from one watershed of each vegetation type. Chloride (Clswi) and water (
v) accumulation with depth were used to identify portions of the regolith with different fluxes. The calculated moisture flux (m yr–1) is reported next to the appropriate straight-line segment (e.g., 0.0031 for the A and Bw horizons of the chaparral channel). Inflection points in the cumulative curves were compared with soil horizon boundaries based on the known depth of each sample point. Soil horizons and boundary depths (cm) are indicated. Arrows indicate the transition between input and leaching zones for each profile (averaged in Table 3). Note that minor inflection points frequently coincide with horizon boundaries.
