meuse: Meuse river data set

meuseR Documentation

Meuse river data set


This data set gives locations and topsoil heavy metal concentrations, along with a number of soil and landscape variables at the observation locations, collected in a flood plain of the river Meuse, near the village of Stein (NL). Heavy metal concentrations are from composite samples of an area of approximately 15 m x 15 m.




This data frame contains the following columns:


a numeric vector; Easting (m) in Rijksdriehoek (RDH) (Netherlands topographical) map coordinates


a numeric vector; Northing (m) in RDH coordinates


topsoil cadmium concentration, mg kg-1 soil ("ppm"); zero cadmium values in the original data set have been shifted to 0.2 (half the lowest non-zero value)


topsoil copper concentration, mg kg-1 soil ("ppm")


topsoil lead concentration, mg kg-1 soil ("ppm")


topsoil zinc concentration, mg kg-1 soil ("ppm")


relative elevation above local river bed, m


distance to the Meuse; obtained from the nearest cell in meuse.grid, which in turn was derived by a spread (spatial distance) GIS operation, horizontal precision 20 metres; then normalized to $[0,1]$


organic matter, kg (100 kg)-1 soil (percent)


flooding frequency class: 1 = once in two years; 2 = once in ten years; 3 = one in 50 years


soil type according to the 1:50 000 soil map of the Netherlands. 1 = Rd10A (Calcareous weakly-developed meadow soils, light sandy clay); 2 = Rd90C/VII (Non-calcareous weakly-developed meadow soils, heavy sandy clay to light clay); 3 = Bkd26/VII (Red Brick soil, fine-sandy, silty light clay)


lime class: 0 = absent, 1 = present by field test with 5% HCl


landuse class: Aa Agriculture/unspecified = , Ab = Agr/sugar beetsm, Ag = Agr/small grains, Ah = Agr/??, Am = Agr/maize, B = woods, Bw = trees in pasture, DEN = ??, Fh = tall fruit trees, Fl = low fruit trees; Fw = fruit trees in pasture, Ga = home gardens, SPO = sport field, STA = stable yard, Tv = ?? , W = pasture


distance to river Meuse in metres, as obtained during the field survey


row.names refer to the original sample number.

Soil units were mapped with a minimum delination width of 150 m, and so somewhat generalize the landscape.

Approximate equivalent World Reference Base 2002 for Soil Resources names are: Rd10A Gleyic Fluvisols; Rd90C Haplic Fluvisols; Bkd26 Haplic Luvisols. Units Rd90C and Bkd26 have winter groundwater > 80cm, summer > 120cm depth.
