calc_gxg: Calculate GxG's of HydroMonitor ObservationWell data.

In KeesVanImmerzeel/menyanthes: Handle HydroMonitor Data

Calculate GxG's of HydroMonitor ObservationWell data.

Description

Percentile values of observed groundwater heads are calculated according to:

Usage

calc_gxg(hm)

Arguments

hm	HydroMonitor Observation Well data as read by read_export_csv

Details

GxG's of observations of every filter is calculated.

Value

Characteristics of monitoring well (meta data, read_export_csv) with the following fields added:

• AHG & AHG_MV 99,85 % value of observed heads (relative to REF, relative to soil surface level).

• MHG & MHG_MV 97,7 % value of observed heads (relative to REF, relative to soil surface level).

• GHG & GHG_MV 84,1 % value of observed head (relative to REF, relative to soil surface level).

• GG & GG_MV 50% value of observed heads (relative to REF, relative to soil surface level).

• GLG & GLG_MV 15,9% value of observed heads (relative to REF, relative to soil surface level).

• MLG & MLG_MV 2,3% value of observed heads (relative to REF, relative to soil surface level).

• ALG & ALG_MV 0,15% value of observed heads (relative to REF, relative to soil surface level).

• n Number of observations used to calculate percentile values.
