| General Comments: | Percent imperviousness of urban (PIU) is an important factor to urban water balance.
The impact of PIU on catchment water balance is way more important than area changes.
Changes in PIU cannot be ignored in long-term scale research.
Ignoring PIU change may underestimate potential risks in long-term changes. |
