In bmcnellis/RSFIA: FIA Tree Mortality Analysis

Description

Multiple utilities for working with DAYCENT.

Function parameters, in no particular order:

Usage

DAYCENT_utils()

daymet_to_daycent(mydmwfiles)

ksat(sand, clay, soc, DF = 1, gravel = 0)

field_cap_df(sand, clay, soc, DF)

theta_sdf(sand, clay, soc, DF)

theta_s(sand, clay, soc)

field_cap(sand, clay, soc)

ro_df(thetas, DF = 1)

wilt_point(sand, clay, soc)

bdens(thetas, DF = 1, gravel = 0)

Arguments

sand	Fraction of sand
clay	Fraction of clay
soc	Soil organic matter percent
DF	Density factor between 0.9 and 1.3
gravel	Gravel percent by weight
thetas	Saturation water content, w/o compaction Multiple functions came from: https://github.com/ldemaz/rcropmod

Functions

• daymet_to_daycent: Reads .dmw files and converts to .wth

• ksat: Saturated hydraulic conductivity, including gravel effects.

• field_cap_df: Calculated field capacity accounting for compaction

• theta_sdf: Calculates saturated water content, accounting for compaction

• theta_s: Calculates saturated moisture content

• field_cap: Calculates field capacity

• ro_df: Matric density accounting for compaction

• wilt_point: Calculate wilting point

• bdens: Bulk density accounting for compaction plus gravel
