| Abstract: | The Laoha River catchment,Liaohe River Basin in the semi-arid region of northern China is selected for study.The interception evaporation,canopy transpiration and soil evaporation are computed by a physically-based two-source potential evapotranspiration model in each grid cell of the basin.The calculated potential evapotranspiration is regarded as the input of the hybrid runoff model instead of the pan evaporation.Then the grid-based distributed hydrologic model is built for daily runoff simulation during ... |
| Keywords: | Evapotranspiration hybrid runoff land cover semi-arid region Laoha River catchment |
