ind_gw_target: Modify a groundwater recharge indicator with a target

In OBIC: Calculate the Open Bodem Index (OBI) Score

Modify a groundwater recharge indicator with a target

Description

This function modifiers the groundwater recharge indicator with a correction factor based on the soiltype and groundwaterclass. Wetter groundwaterclasses give higher values, peat gives higher values than clay, and clay higher than sand.

Usage

ind_gw_target(D_RISK_GWR, B_SOILTYPE_AGR, B_GWL_CLASS, B_AREA_DROUGHT = FALSE)

Arguments

D_RISK_GWR	(numeric) Groundwater recharge risk (distance to target, i.e. the 1 - I_E_GWR)
B_SOILTYPE_AGR	(character) The agricultural type of soil
B_GWL_CLASS	(character) The groundwater table class
B_AREA_DROUGHT	(boolean) is the field located in an area with high risks for water deficiencies (options: TRUE or FALSE)

Value

D_OPI_GW (numeric) The opportunity index for groundwater recharge. This is the groundwater recharge indicator score modified by a target (nl: opgave). This target is a measure for how relevant this soil function is given, in this case, the soiltype and groundwaterclass.

Examples

ind_gw_target(0.5, 'zeeklei', 'IVu', FALSE)
