ecoval-package: Procedures for the Ecological Assessment of Surface Waters

In ecoval: Procedures for Ecological Assessment of Surface Waters

Description

Functions for evaluating and visualizing ecological assessment procedures for surface waters.

Functions to generate branches (modules) of the assessment value function:

Swiss river assessment program and individual modules (MSK, https://modul-stufen-konzept.ch):

msk.create,
msk.morphol.1998.create,
msk.hydrol.2011.create,
msk.physapp.2007.create,
msk.nutrients.2010.create,
msk.diatoms.2007.create,
msk.invertebrates.2010.create,
msk.fish.2004.create,
msk.macrophytes.2017.create.

Additional modules in the evaluation state:

val.pesticides.create,
val.micropoll.create,
val.heavymetals.create,
val.spear.create,

val.invertebrates.create,

Integrative assessment value function considering modules of the Swiss assessment program and modules at the evaluation stage:

ecoval.river.create,

Moduls of the Swiss lake assessment program (see https://modul-stufen-konzept.ch):

lake.morphol.2016.create,

Node names, attribute names and identifiers for attribute levels (if not numeric) can be translated into different languages. See:

ecoval.dict,
ecoval.translate,
