I don't have any math to back me up but from experience -- you'll loose
about two inches per week -- this is relative to amount of sun, wind -- and
of coarse -- rain. (remarkably, relative humidity has little effect)

Have any of you needed to calculate water loss due to evaporation and/or
splashing on an outdoor water feature? Can you suggest a way to estimate
it?
The specific details are that we're planning to have about 200 sf of water
surface on a recirculating flow. Visitors will have access to it, but we
won't offer any buckets, scoops, or other obvious invitiations to pour
water on the ground.
thanks,
