This function calculates environmental flow requirements (EFR) for MAgPIE retrieved from LPJmL monthly discharge and water availability using the method of Smakthin et al. (2004)

)Arguments
- lpjml
Defines LPJmL version for crop/grass and natveg specific inputs
- climatetype
Switch between different climate scenarios
- stage
Degree of processing: raw, smoothed, harmonized, harmonized2020
- LFR_val
Strictness of environmental flow requirements
- HFR_LFR_less10
High flow requirements (share of total water for cells) with LFR<10percent of total water
- HFR_LFR_10_20
High flow requirements (share of total water for cells) with 10percent < LFR < 20percent of total water
- HFR_LFR_20_30
High flow requirements (share of total water for cells) with 20percent < LFR < 30percent of total water
- HFR_LFR_more30
High flow requirements (share of total water for cells) with LFR>30percent of total water
- seasonality
grper (default): EFR in growing period per year; total: EFR throughout the year; monthly: monthly EFRs
- cells
lpjcell for 67420 cells or magpiecell for 59199 cells
