5.5 Summary

This study presented a study case on distributed water resource assessment on upstream Hanjiang River.The study area was divided into 12 routingrelated catchments along the upstream reach of Hanjiang River.The model wascalibrated by the comparison of simulated and observed hydrograph at eachcatchment outlet and results yielded good fittings.The routing parameters werecalibrated and results showed that catchments with larger area had more obvious routing time lag effect.The largest part of surface runoff amount was generated from vegetated area.Except the open water evaporation，the transpiration had taken the most part.The spatial distribution of evapotranspiration alsoindicated that the upstream catchments of Hanjiang River had much lowerevapotranspiration than the downstream ones.Moreo ......     （共982字）    [阅读本文]>>
