Insert shows a detailed schematic of the water control structures surrounding WCA 1 and the location of the soil sampling sites within WCA 1. The term STA denotes storm water treatment area, L denotes canals, S denotes pumps.

Characteristic semivariograms of selected soil and floc properties: (a) floc depth, (b) floc bulk density (BD), (c) soil total phosphorus (TP), (d) soil total calcium (TCa), (e) floc C to N ratio, and (f) floc total iron (TFe). Some properties were natural log transformed. Thick line, indicated with label M, represents the fitted variogram model; thinner line represents the experimental variogram and is indicated with the label D1. The unlabeled horizontal line represents the total sample variance. The distance (x axis) was measured in meters.

Spatial distribution of floc total phosphorus (TP) (a), total inorganic phosphorus (TIP) (b), total calcium (TCa) (c), soil total phosphorus (TP) (e), total inorganic phosphorus (TIP) (f), and calcium (Ca) (d) in Water Conservation Area 1 (WCA 1), sampled in March 2003 and August 2004. The scale bar shows the extent of the estimated properties.
