外文摘要：The basin of the Yellow River is among the most complex in the world， considering the extreme conditions in the natural environment， the major structural interventions over past centuries and planned for the future， and the significant potential hazards to those dependent on the river's resources and vulnerable to its extreme behaviour。 Effective river management demands the best and most appropriate technology that incorporates a comprehensive representation of the physical phenomena over an appropriate space and time。 The diverse nature of the physical processes， their space and time scales require a number of different analytical approaches and mathematical models to achieve a sound understanding of the past performance， present conditions and the impact of future developments。 Among these are: 1。 Basinwide distributed hydrologic， soil erosion and overland transport model to simulate the effect of degradation of land resources on the river system， and the impact of soil and water conservation measures 2。 Basinwide water resources model， with rainfall， potential evaporation， and demands as the primary driving inputs; and the output of water allocations based on a range of user defined criteria 3。 Hydrologic - hydrodynamic model with flood forecasting and a one dimensional morphologic component， for flood forecasting and reservoir and retention basin flood control operation in the lower reach， and for general planning and design 4。 Two dimensional morphologic model for reservoir sedimentation and the scheduling of water and sediment releases 5。 Two dimensional morphologic model for the entire lower reach， for the analysis of the impact of reservoir operation strategies， and the planning of river training works。
