Book Description
Aquatic habitat quality is dependent on water quality, bed slope, water temperature, dissolved oxygen, substrate, vegetation, and hydraulic parameters in the stream system. The Riverine Community Habitat Assessment and Restoration Concept (RCHARC) is a methodology developed by the U.S. Army Engineer Waterways Experiment Station, Environmental Laboratory, to compare hydraulic parameters (depth and velocity) between natural, degraded, and restored channel reaches. The methodology is generally applied to alternate reaches in the same stream; therefore, the habitat quality variables must also be closely matched. RCHARC assumes that if the diversity of hydraulic and habitat quality parameters for a 'comparison standard' reach can be replicated in the stream restoration reach, then the aquatic habitat quality can be enhanced. The RCHARC Methodology has been successfully applied to large, warm-water rivers. The objective of this study was to Beta test the RCHARC methodology for its applicability to cold-water flood control channels. The results of the Beta test and analysis conducted at Rapid Creek, South Dakota, are reported herein. The field site selected for testing the RCHARC methodology was Rapid Creek, located in and adjacent to Rapid City, SD. Natural (comparison standard) and restored reaches were identified for comparison. Field crews were dispatched in June and October 1993 to collect field data during high- and low-flow conditions, respectively. Data collected included cross-sectional profiles, discharge, depth and velocity pairs, dissolved oxygen, water temperature, thalweg and water surface elevation profiles, suspended and bed-load samples, armor layer and substrate samples, and photographic documentation.

Book Description
This technical paper reviews current information on the effectiveness of habitat rehabilitation techniques for inland fisheries, based on published evaluations of projects including studies on roads improvements and sediment reduction, riparian and floodplain rehabilitation, placement of habitat structures in lakes and streams, and the addition of nutrients to increase aquatic production. It also sets out information on planning, prioritising and monitoring rehabilitation projects.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Description
This manual provides guidelines for the design and construction of relocated channels, and describes measures that will lead to rapid recovery of new channels by natural processes. Good design, and implementation of these measures can greatly reduce the adverse effects of stream relocation.
