摘要: The climatic processes such as changes in precipitation, temperature and atmospheric CO2 concentration can intensify the effects on water resources. An assessment of long-term climate change resources is essential to development quality improvement programs. This study was conducted Upper Pearl River Watershed (UPRW) east-central Mississippi assess potential future average mean monthly stream flow from five spatially distributed U. S. Geological Survey (USGS) gage stations UPRW using Soil Water Assessment Tool. model calibrated (January 1981 December 1994) validated 1995 September 2008) measured data. determined good very performance for prediction (R2 E 0·60 0·86) between predicted values. root square error values (from 14 37 m3 s−1) were estimated at similar levels errors during calibration validation. results showed that (50 years) sensitivity due found greatest a result percentage precipitation followed by carbon dioxide (CO2) temperature. simulation scenarios compared with base scenario all USGS an decrease 54 67%) increase 67 79%) depending spatial characteristics stations. Overall, indicate hydrology sensitive these could stimulate increased streamflow generation watershed. Copyright © 2010 John Wiley & Sons, Ltd.
