SWRC
)SWRCs
convert between soil water content and soil water potential
using a set of parameters, see swrc_swp_to_vwc()
and swrc_vwc_to_swp()
.
The SWRC
parameters may be estimated from soil properties with suitable
pedotransfer functions PTFs
, see ptf_estimate()
.
The SWRC
parameters can be checked for consistency with check_swrcp()
.
