Book Description
These proceedings of a NATO Advanced Research Workshop on "Environmental Reconstruction in Headwater Areas" provide a landmark in the evolution of a distinctive movement, perhaps an emerging new philosophy, within the practice of headwater management. The Headwater Control movement traces its history back to the First International Conference on Headwater Control, Prague, 1989. Throughout this brief history, Headwater Control has remained a typical environment movement 'ad hocracy'. At its meetings, for every convert to the multidisciplinary, integrative, practical, interventionist, and above-all 'green' ideals of the group, there have been several delegates who have found the whole concept both new and slightly incomprehensible. One reason for this has been the Headwater Control practice of trying to bring together scientists, practitioners, policy-makers and non-government environmentalist organisations. The group's larger meetings have always been federal gatherings. Sponsorship has been shared with invited participation from associations representing hydrological science, soil conservation, erosion control, forestry, environmental activism and so forth. These delegations may have included fellow travellers in the work to protect headwater environments, but their main concerns have not necessarily coincided with the Headwater Control group's prescriptions for the environmental regeneration of headwater regions. The Liberec Workshop, whose proceedings are distilled into this volume, provided a first opportunity for the scattered supporters of Headwater Control to talk among themselves and fmd out to what degree there really is a shared vision of the way forward in headwater management, restoration and protection.

Book Description
Internationally, the wetlands of headwater and upland regions provide many valuable environmental services. This book moves towards a more comprehensive inventory of the benefits and costs of headwater wetlands. It evaluates the research that tries to understand the tolerances, exchanges, checks and balances within headwater landscapes and the downstream impacts of changes in wetlands. It employs case studies and reviews from 21 nations spanning Europe, Africa, Asia and the Americas. It explores the new policy frameworks, changes in land husbandry, new systems for community education, participatory processes and technological interventions required for the effective management of headwater wetlands and the full integration of wetlands (including newly constructed wetlands) into environmental management and planning. In the past, most research dealt with wetlands as isolated features, this book examines wetlands in their watershed management context.

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
Abstract: Throughout the American Midwest, headwater streams flowing through agricultural fields have been extensively modified to accommodate subsurface drainage systems, normally resulting in deepened, straightened, and widened headwater streams. Some of the most dense drainage and riparian ecosystem alteration in the world have occurred there. This dissertation includes three studies that investigate the design and analyses of stream restoration in the Midwest, USA. A segment of Grave Creek on The Ohio State University's Marion campus in Ohio, USA, with its lack of riparian ecosystems, illustrates the transformation of a natural fluvial ecosystem to an unstable and "simplified" aquatic environment that requires continued maintenance and provides little value to the surrounding landscape or to the university. To restore the natural ecological stability of OSU Marion's "back yard" and to provide habitat improvement to Grave Creek and its surrounding landscape on the OSU Marion campus, we designed a restoration of 1.1 km of Grave Creek meandering to the east of an existing sewer line, using a two-stage channel technique, and about 0.6-0.8 ha of adjacent wetland. We estimate that restoration on this scale would cost about US$ 200,000-300,000, not including monitoring of the results. To evaluate the feasibility of connecting streams and rivers to a riparian diversion wetland, a small-scale bioreserve pond/wetland (0.07 ha) created in 2002 at the Olentangy River Wetland Research Park was connected at its inflow to an adjacent stream. This research investigated the biological and water quality connection of the diversion wetland and adjacent stream. Before the flow-through conditions were established in 2009, we demonstrated with mark-recapture techniques that the wetland already was a biorefuge for fish under extreme conditions; two species (Centrarchidae) captured in the stream before a total drawdown of the stream were found in the wetland a year later. In addition, the 4 °C bottom water in the wetland, probably due to groundwater input, provided a warmer refuge for fish. Stream water quality, downstream of the wetland outlet, generally improved with hydrologic pulsing after flow-through. Mean removal per flood pulse for nitrate-nitrite, total nitrogen (TN), soluble reactive phosphorus (SRP), total phosphorus (TP) were 1.81 g-N m-2, 1.02 g-N m-2, 0.014 g-P m-2, and 0.004 g-P m-2 respectively. The wetland exported 2.8 g-C m-2 of organic carbon. A greater attenuation of NO3- and TP occurred in the marshy outlet channel section of the wetland than in the open water section. Similar designs should be applied to other locations to examine their function under different climatic and hydrological conditions. While straightened stream channels and drained wetlands have adversely impacted streams and rivers, partial or total reconstruction of channels is frequently attempted to restore these headwater streams. There are different approaches to reconstructing the channel, yet there is little evidence that indicates which one promises more success and there has been no experimental work to evaluate these approaches. This third study provides the design of three different experimental channels--two-stage, self-design and straightened channels--on a human-constructed flowing stream at the Olentangy River Wetland Research Park, Columbus, Ohio for long-term evaluation of headwater stream evolution after restoration. The stream receives a continuous river-programmed flow of pumped water from the Olentangy River. Using streamflow and stage data for the past 12 years, a channel forming discharge of 0.18 m3/s was estimated based on calculations of bankfull discharge, effective discharge and recurrence interval. The resulting stream channels, after constructed, would be used to evaluate physical, chemical and biological responses to different channel forms over a decade-long experiment. We hypothesize that the three stream restoration designs will converge in time.

Book Description
Headwaters are fragile environments threatened by anthropogenic actions. The regeneration of headwaters calls for a practical approach through integrated environmental management. This book discusses various issues concerning headwater regions of the world under wide-ranging themes: climate change impacts, vegetal cover, sub-surface hydrology, catchment and streamflow hydrology, pollution, water quality and limnology, remote sensing and GIS, environmental impact assessment and mitigation, socio-economic impacts, public participation, education and management, and integrated watershed management. This book aims to bring about an awareness in sustainable regeneration of headwater regions and particularly highlighting the problems of environmental management in highlands and headwaters. These regions consist of great reserves of natural resources which need to be exploited and managed sustainably.
