FloodnetPool(
  x,
  target,
  period = c(2, 5, 10, 20, 50, 100),
  distr = NULL,

  nsim = 2000,

  verbose = TRUE
)

Arguments

x

Hydrometric data of the form: site, year, value.

target

site ID of the target.

period

Return periods for which the flood quantiles are estimated.

distr

Regional distribution.

tol.H

Heterogeneity measure. A stopping criterion representing the minimal heterogeneity level accepted for a pooling group.

nsim

Number of bootstrap samples used for inference.

level

Confidence level.

corr

Coefficient of correlation used for simulation. The same value is assumed between each pair of sites.

out.model

Logical. Should the model be output. This corresponds to the output of FitRegLmom. Otherwise only the estimated flood quantiles are returned.

verbose

Logical. Should message and warnings be returned.

Details

Estimation is carried out by the L-moment algorithms. See FitRegLmom and PoolRemove for more details. If not provided the distance between sites is evaluated using the distance between the regularity and timing of the annual flood peaks. Confidence intervals and standard deviation are evaluated by a parametric bootstrap. An intersite correlation is estimated and used to simulate from a multivariate normal distribution.
