Plate 27 Influences of interpolation on the results of an erosion/deposition model: (a) observed depth of colluvial deposits in the sampling points and as interpolated raster shown in colour; (b) artificial erosion/deposition pattern predicted from a DEM interpolated from contours by spline with tension set too high; and (c) realistic erosion/deposition pattern predicted using a DEM interpolated from contours by regularised spline with tension and smoothing.
