Land Use (L) and Lake Concentration (P) Phosphorus Loading
�L
= W / As
�
�P
= L / (11.6 + 1.2qs)
The amount of phosphorus
entering LPN W term was further manipulated to assign loading due to
land-use effects independently from other sources.
L is annual phosphorus
areal loading in kg/m2/yr.This
value comes from dividing the best estimate phosphorus loading W�s by the
lake surface area (A sub s).
P is the predicted
phosphorus concentration in LPN.The areal loading is divided by the term 11.6 +1.2qs, which
corresponds to the settling velocity of phosphorus and areal water loading
in the lake.
