filterlayer: Calculate grain size distribution of a filter layer

Description

Tool to calculate the range of the grain size distribution of a filter layer.

Usage

filterlayer(
  d15B,
  d50B,
  d15U,
  d50U,
  d85U,
  dmax = 400,
  plot = TRUE,
  fuller = FALSE
)

Value

A list with the following components:

d15min

Minimum d15 of filter layer [mm].

d15max

Maximum d15 of filter layer [mm].

d50min

Minimum d50 of filter layer [mm].

d50max

Maximum d50 of filter layer [mm].

d85min

Minimum d85 of filter layer [mm].

Arguments

d15B

Numeric. d15 of block [mm].

d50B

Numeric. d50 of block [mm].

d15U

Numeric. d15 of soil [mm].

d50U

Numeric. d50 of soil [mm].

d85U

Numeric. d85 of soil [mm].

dmax

Numeric. Maximum grain diameter of filter layer [mm].

plot

Logical. If TRUE, the results are plotted (default is TRUE).

fuller

Logical. If TRUE, adds curves of Fuller distributions with exponents 0.5 < q < 1.5 to the plot. For an ideal grain size distribution, q is estimated as 0.5 (default is FALSE).

Examples

# Calculate range of the grain size distribution
filterlayer(1000, 1500, 5, 10, 20, 400)

# Calculate range of the grain size distribution and add Fuller curves
filterlayer(1000, 1500, 5, 10, 20, 400, fuller = TRUE)
