Your landscape design scenario is a new landscape that utilizes plant species with very low evapotranspiration value. The microclimate is high with an unprotected environment in a windy area. The plant density is moderate since it is a new landscape. What is the Landscape Coefficient for this landscape using the numbers provided in the table below
HIGH MODERATE LOW VERY LOW
SPECIES FACTOR .8 .5 .2 .1
DENSITY 1.2 1.0 .7
MICROCLIMATE 1.3 1.0 .6
Landscape Coefficient (KL) for any landscape depends on three major factors-
a) Plant species existing in the landscape
b) Shade and microclimate
c) Plant density
While evaluating, Landscape Coefficient (KL) the above three factors are taken into consideration and an adjustment factor for all of these three factors is included in the mathematical relation as given below –
Where,
i s Adjustment factor for plant species
is Adjustment factor for shade or microclimate
is Adjustment factor for plant density
For low evapotranspiration value, the corresponding values of these adjustment factors will be
is 0.2
is 0.6
is 0.7
Substituting the given values in above equation, we get
