A review of river management history in various countries is used in this thesis to discuss the future development trends of river management and the relationship between river health and river management. Based on the characterization and assessment of river health, Five components of stream condition are presented in this thesis to characterize river health: water quality, aquatic life, physical form, hydrology and streamside zone. It is obtained by comparing the methods and criteria that have been developed by others and reviewing the river assessment practices in various countries. Accounting for the features of urbanization region in plain river network, an indicator system for river health assessment which provides scores for 5 subindices and 17 indicators is established. With almost 200 stream reaches in Shanghai as objective of study and Liwa stream and Zhangjiabang Creek as case study, the application of river health assessment in the planning, baseline survey and post-project appraisal of river management is explored by collecting historical literature and field monitoring. Consequently, some suggestions to improve river management effectiveness are presented from the angle of river health.

The typical form of tactical missile and noses of modern fighter aerocraft are slender bodies. With the requirements of high agility and maneuverability for modern fighter and missiles, it is more common to fly at high angle of attack even beyond post stall. But, the flowfield around the slender body at high angle of attack will became complicated multi-vortices asymmetric and exert a high side force and yaw moment on the body even if the body is axisymmetric and at zero sideslip.

The results show that river health indicators are reflected in some extent during the process of baseline survey and success criteria setting among the river regulation planning in Shanghai. While there are certain deficiencies in river condition evaluation, setting of management objective and post-evaluation procedure, attention should be paid to the development of river health assessment from the start of rivrer management planning. The river health assessment of Liwa stream reveals that it is in a poor condition. Specific issues include: the alteration of natural hydrological condition, degradation of water quality, loss of biotic integrity, and modification of physical form. Its high time to introduce river health assessment for tracking changes or trends of river condition and selecting effective management strategies. Post-evaluation on the benefits of Zhangjiabang Creek regulation shows that the water quality, aquatic community and riverine vegetation are improved and great ecological and environmental benefits are demonstrated. But from the angle of river health, there are some problems in water quality, physical form and management strategies. Thus, the whole process of river health assessment should be adopted as a new tool to improve the effectiveness of river management.
实证研究结果表明：(1)上海地区河道整治项目规划在现状调查、整治目标设定等环节初步体现了对河流健康状况的关注，但在现状评价、管理目标设定以及后评估程序设置等方面仍有所欠缺，今后应聚焦于从规划源头开始将河流健康状况贯穿于现状调查与评价、目标设定、后评估等河流管理的全过程；(2)以丽娃河为对象的河流健康状况现状评估及问题诊断结果显示，水文条件不佳、水质黑臭、河流生物缺乏以及河流形态改造严重等正在成为制约河流生态系统的重要因素，急需从河流生态系统健康视角剖析存在问题，并选择合理有效的河流整治措施；(3)基于河流健康状况评估方法的河道整治后评估结果显示，张家浜综合整治使得河流水文、水质以及河岸带状况有所改善，体现了较好的生态环境效益，但从河流健康状况角度而言，河流水质、河流形态、管理措施等方面仍存在一定的不足，全过程的河流健康状况评价应被视为改进河道整治项目有效性的崭新手段。
