View larger version (93K): [in a new window]   Fig. 1. (a) Terrain model of the Sæby site indicating the soil and crop sampling points. The open circles represent additional sampling points for 137Cs inventories only. The boundary of the digital elevation model corresponds to the field border. (b) Distribution of different landform elements within the sampling area. The lines denote elevation contours and the cell size shown is 10 by 10 m. D, divergent; C, convergent; SH, shoulder; BS, backslope; FS, footslope; TS, toeslope.

Negative values indicate soil loss and positive values indicate soil gain. Values between –10 and +10% represent stable areas.
