Non‐existing crop stages according to the BBCH Compendium are represented by a dash (–).
Crop interception values in parentheses are not applicable at FOCUS sw Step 3 as there is no crop present in the models at this BBCH stage (e.g. after harvest); default crop interception set to zero in SWASH.
Evergreen all year round, constant crop interception not related to BBCH stage.
Considered to represent established turf all year round.
In line with revised run‐off parameterisation for tall permanent crops in PRZM; note that there is no soil cover (bare soil, no crop interception) below the crop canopy in citrus, hops and olives (also refer to Section 3.8.1 and Appendix Q).
Adopted from Olesen and Jensen (2013); according to this reference crop interception at BBCH 92 and 97 is 70% and 0%, respectively (no other BBCH stage exists in hops for BBCH 90–99).
No crop interception given in EFSA (2014) for this BBCH stage; default crop interception set to zero in SWASH.
Same as peas in FOCUS groundwater.
Same as in FOCUS surface water Step 2.
Harvested at BBCH 50; default crop interception set to zero in SWASH for BBCH 50 and onwards.
Same as onions in FOCUS groundwater.
Same as tomatoes in FOCUS groundwater.
Same as cabbage in FOCUS groundwater.
Same as carrots in FOCUS groundwater.
