Hello all,
In URBPARM_LCZ.TBL,we use IRHO((from 0 to 1 for each hour of the day): it allows to turn on drip irrigation over the roof, for the hours of the day desired. The value of 1 correspond to an irrigation of 25 L/m2/week, and lower values to its fraction.) to describe the irrigation in green roof.
In module_sf_bep_bem.F,I found that:
real h_water
parameter(h_water=0.0009722) !mm of irrigation per hour
if(sum(irho).gt.0)then
irri_per_ts=h_water/sum(irho)
else
irri_per_ts=0.
endif
if(irho(int(nhourday)+1).ne.0)then
irri_now=irri_per_ts
else
irri_now=0.
endif
I want to know the role of h_water and its mathematical relationship with irho,because i can't find out the relationship between h_water=0.0009722 and irho=1 (irrigation of 25/L/m2/week) . Also, if I want to further modify the irrigation of the green roof, what others can I refer to for the modification?
I would appreciate any help!
