Description

Outputs Sacramento Parameters and NSE value with expuh routing model.

Usage

sacramentoexpuhSCE(inputdata, seed, delay = 0, uztwm = c(1, 150),
  uzfwm = c(1, 150), uzk = c(0.1, 0.5), pctim = c(1e-06, 0.1),
  adimp = c(0, 0.4), zperc = c(1, 250), rexp = c(0, 5), lztwm = c(1,
  500), lzfsm = c(1, 1000), lzfpm = c(1, 1000), lzsk = c(0.01, 0.25),
  lzpk = c(1e-04, 0.25), pfree = c(0, 0.6), etmult = 1, tau_s = c(10,
  1000), tau_q = c(0, 10), v_s = c(0, 1), warmup = 365, ncomplex = 20,
  maxit = 200)

Arguments

inputdata	Input data (requires Data$Q, Data$P, and Data$E) (mm/day)
seed	Random number for sampling within SCE
delay	Time-delay for hydrologic routing
uztwm	Upper zone maximum tension water capacity (mm)
uzfwm	Upper zone maximum free water capacity (mm).
uzk	Lateral drainage rate of upper zone free water expressed as a fraction of contents per day.
pctim	The fraction of the catchment which produces impervious runoff during low flow conditions.
adimp	The additional fraction of the catchment which exhibits impervious characteristics when the catchment's tension water requirements are met.
zperc	Maximum percolation (from upper zone free water into the lower zone) rate coefficient.
rexp	An exponent determining the rate of change of the percolation rate with changing lower zone water contents.
lztwm	Lower zone maximum tension water capacity (mm)
lzfsm	Lower zone maximum supplemental free water capacity (mm)
lzfpm	Lower zone maximum primary free water capacity (mm)
lzsk	Lateral drainage rate of lower zone supplemental free water expressed as a fraction of contents per day
lzpk	Lateral drainage rate of lower zone primary free water expressed as a fraction of contents per day
pfree	Direct percolation fraction from upper to lower zone free water (the percentage of percolated water which is available to the lower zone free water aquifers before all lower zone tension water deficiencies are satisfied)
etmult	Multiplier applied to Data$E to estimate potential evapotranspiration (default is 1)
tau_s	time constraints
tau_q	time constraints
v_s	fractional volume
warmup	Number of Days to Warmup the hydrologic model
ncomplex	Number of Complexes for SCE
maxit	Maximum number of iterations
