R Documentation

Streamflow-precipitation elasticity

Description

Streamflow-precipitation elasticity

Usage

sig_Stream_elas.Sawicz(
  Streamflow,
  Preciptation,
  t_scale = apply.yearly,
  wateryear_start_m = 1,
  fct_stat = mean
)

sig_Stream_elas.Sanka(
  Streamflow,
  Preciptation,
  t_scale = apply.yearly,
  wateryear_start_m = 1,
  fct_stat = mean
)

Arguments

`Streamflow`	[xts]-2D(time, space) Time serious Streamflow in difficult location.
`Preciptation`	[xts]-2D(time, space) Time serious Preciptation in difficult location.
`t_scale`	[function] \|apply.quarterly\| for quarterly, \|apply.yearly\| for yearly.
`wateryear_start_m`	[num]-\|2\|3\|4\|5\|6\|7\|8\|9\|10\|11\|12\| for Feb. ... Dec.
`fct_stat`	[function] statistic function like mean, media, max and so on

Value

stream elasticity [xts]-2D(time, space) in time scale

Examples

rslt <- sig_Stream_elas.Sawicz(xts_Q, xts_P)
rslt <- median(sig_Stream_elas.Sawicz(xts_Q, xts_P, wateryear_start_m = 10))
rslt <- sig_Stream_elas.Sanka(xts_Q, xts_P)
rslt <- median(sig_Stream_elas.Sanka(xts_Q, xts_P, wateryear_start_m = 10))
