XXX老妇人60>探海松摘要：The dam impounding White Rock Lake was completed in 1910 to provide water for the City of Dallas. Since then, land u on the watershed has changed from entirely rural to over 77 percent urban. A model called SWRRB (Simulator for Water Resources in Rural Basins) was utilized to determine the effect of urbanization on water and diment entering the lake. The simulation results show that, if urbanization had not occurred, then the annual surface runoff would be 135 mm rather tha
n 151 mm and the annual diment yield would be 4.4 t/ha rather than 4.1 t/ha. Also, the effect of urbanization on delivery ratios was shown and a positive linear correlation was found. Finally, the weather generator in SWRRB was utilized to estimate the loss of rervoir capacity until 2050 for three different land u management scenarios.
