ind_gw_recharge {OBIC}

Calculate groundwater recharge of a soil

Description

This function calculates an index score for groundwater storage based on precipitation surplus, infiltration at saturation, sealing risk, drainage and subsoil compaction

Usage

ind_gw_recharge(B_LU_BRP, D_PSP, D_WRI_K, I_P_SE, I_P_CO, B_DRAIN, B_GWL_CLASS)

Arguments

B_LU_BRP

(numeric) The crop code from the BRP

D_PSP

(numeric) The precipitation surplus per crop calculated by calc_psp

D_WRI_K

(numeric) The value for top soil permeability (cm/d) as calculated by calc_permeability

I_P_SE

(numeric) The indicator value for soil sealing

I_P_CO

(numeric) The indicator value for occurrence of subsoil compaction

B_DRAIN

(boolean) Are drains installed to drain the field (options: yes or no)

B_GWL_CLASS

(character) The groundwater table class

Value

The evaluated score for the soil function to improve groundwater recharge. A numeric value between 0 and 1.

Examples

ind_gw_recharge(B_LU_BRP = 265,D_PSP = 200, D_WRI_K = 10, I_P_SE = 0.6, I_P_CO = 0.9, 
B_DRAIN = FALSE, B_GWL_CLASS = 'GtV')
ind_gw_recharge(B_LU_BRP = 233, D_PSP = 400, D_WRI_K = 10, I_P_SE = 0.4, I_P_CO = 0.2, 
B_DRAIN = TRUE, B_GWL_CLASS = 'GtII')
