RIVER TRAINING AND RESTORATION
Many river training and river use projects, including damming, water diversion, levee construction, meanders cutoff and waste water and sewage discharging, disturbed the river eco-system and caused ecological stresses. Integrated river training and management aims at reconciling the provision of safety to the people, habitat and ecological system stability, and sustainable use of the land and water. The integrated river management comprises: 1) taking the watershed, upper stream basin including the tributaries, middle and lower reaches and the estuary as an integrated entity in the planning, design and management; and 2) mitigating or controlling the negative impacts on hydrology, fluvial processes, land use and river use, environment and ecology while in achieving economic benefit from water resources development, flood safety management and hydropower exploitation. Nevertheless, river regulation projects are local and specific purposes-oriented. Presently many river regulation and river training projects are performed with main focal point on economic benefit. Negative effects have been shown in numerous cases. In some cases the negative effects are so serious that humans have to consider to renaturalize the regulated rivers. Only by applying the strategy of integrated river training and management in individual projects the diverse river uses, natural fluvial processes and ecological systems may be harmonized, for which the river regulation projects have to obey several laws.
