bufferdat {VFS}

Parameters for vegetated buffers

Description

Contains parameters describing vegetated filter strips for use in VFS modeling.

Usage

data("bufferdat")

Format

A data frame with 2 observations on the following 3 variables.

Species

Type of buffer

bg

Average stem spacing (cm)

n

Manning's roughness coefficient (s m^(-1/3))

Details

Currently contains data for a cool-season and a warm-season grass buffer.
