calc_AML: Compute AML

In reasonabletools: Clean Water Quality Data for NPDES Reasonable Potential Analyses

Description

Compute average monthly effluent limitation (AML) according to methods in EPA's Technical Support Document for Water Quality-based Toxics Control.

Usage

calc_AML(
  WLAa,
  WLAc,
  WLAhh,
  cv,
  n_samples = 4,
  prob_LTA = 0.99,
  percentile_AML = 0.95
)

Arguments

WLAa	Numeric. Acute wasteload allocation (WLA). All WLA units should be identical.
WLAc	Numeric. Chronic wasteload allocation (WLA). All WLA units should be identical.
WLAhh	Numeric. Human health wasteload allocation (WLA). All WLA units should be identical.
cv	Numeric. Coefficient of variation (CV) of effluent data. See cv_adj function.
n_samples	Numeric. Number of sample observations.
prob_LTA	Numeric (fraction). Allowable exceedance probability of the WLA used to estimate long-term average (LTA).
percentile_AML	Numeric (fraction). Lognormal distribution location for AML.

Value

Numeric value in same units as the WLAs.

Examples

calc_AML(WLAa=4, WLAc=1, WLAhh=10, cv=0.6)
