摘要：The permeation of water into groundwater in an urban environment is considerably differ-ent than that in an untransformed landscape. Built-up and open surfaces have very different proportions of impermeable surfaces. Due to urban land use on Ljubljansko polje, the loss of permeating precipitation water is more than 0.5m3/s or 190 mm of precipitation.
