Fig. 1. Relationship between cumulative days from start of study in fall and geometric mean diameter (GMD) for (a) Fairfield (1992-1993), (b) Wilson (1993-1994), and (c) Lethbridge (1994-1995) sites. For ease of interpretation the x-axis label is shown as date rather than cumulative days. Cumulative days are shown above or below data points. Day 1 = 18 Sept. 1992 at Fairfield; 26 Oct. 1993 at Wilson, and 30 Aug. 1994 at Lethbridge. Error bars = 1 standard error

Fig. 2. Relationship between cumulative days from start of study in fall and erodible fraction (EF) for (a) Fairfield (1992-1993), (b) Wilson (1993-1994), and (c) Lethbridge (1994-1995) sites. For ease of interpretation, the x-axis label is shown as date rather than cumulative days. Cumulative days are shown above or below data points.

Fig. 3. Relationship between cumulative days from start of study in fall on soil surface roughness (Cpar) for (a) Wilson (1993-1994) and (b) Lethbridge (1994-1995) sites. For ease of interpretation, the x-axis label is shown as date rather than cumulative days. Cumulative days are shown above or below data points. Day 1 = 26 Oct. 1993 at Wilson and 30 Aug. 1994 at Lethbridge. Error bars = 1 standard error
