Channel Rehabilitation: Processes, Design, and Implementation (original) (raw)

Channel modification or channelization activities are listed among the top 10 sources for non-point pollution impacts to rivers (U.S. Environmental Protection Agency (EPA), 1993). Activities such as straightening, widening, deepening, and clearing channels of debris generally fall into this category. These activities can severely impact major river projects such as navigation and flood control, as well as alter or reduce the diversity of in-stream and riparian habitats. River systems maintain stability by providing just the necessary flow to transport the available water and sediment.
