This book presents a comprehensive overview of the first longitudinal study of the downstream response of a major river to the establishment of a large hydropower facility and dams. Peace River, a northward flowing boreal river in northwestern Canada was dammed in 1967 and the book describes the morphological response of the 1200 km downstream channel and the response of riparian vegetation to the change in flow regime over the first forty years of regulated flows. Beginning with a description of the effect of regulation on the flow and sediment regimes of the river, the book proceeds to study changes in downstream channel geometry on the main stem, on the lowermost course of tributaries, and on the hydraulic geometry, the overall morphology of the channel, and riparian vegetation succession. The river is subject to annual freeze-up and break-up, so a chapter is devoted to the ice regime of the river. A chapter compares the effects of two extraordinary post-regulation flood events. The penultimate chapter presents a prediction of the ultimate equilibrium form of the regulated river based on rational regime theory. An online database of all the main observations will provide invaluable material for advanced students of river hydraulics and geomorphology. This book carefully brings together a range of studies that have been previously inaccessible providing a rare and comprehensive analysis of the effects of a big dam on a river, a river that itself represents an example of the kind of system that is likely to receive considerable attention in the future from dam engineers and environmentalists. • An invaluable reference to river scientists, hydroelectric power developers, engineers and environmentalists • Focus on a northward flowing boreal river, a type that holds most of the remaining hydroelectric power potential in the Northern Hemisphere • Exceptional separation of water and sediment sources, permitting study of the isolated effect of manipulating one of the two major governing conditions of river processes and form • Unique example of water regulation and both natural and engineered flood flows • Detailed study of both morphological changes of the channel and of the riparian vegetation • Online data supplement including major data tables and numerous maps. Details of the main observations and provides material for problem study by advanced students of river hydraulics and geomorphology are provided
This study estimates the effect of the unemployment insurance wage replacement rate on reemployment wages in the U.S. using the sample of men in the 1996 and 2001 Surveys of Income and Program Participation. I model employment search behavior in a dynamic discrete time hazard setting with three possible outcomes: finding a full-time job, finding a part-time job, or staying unemployed (continuing the job search). I find that reemployment wages decrease with the unemployment insurance wage replacement rate. Furthermore, the wage replacement rate depresses the prospect of finding full-time work while increasing the prospect of finding part-time work.
A Long-Ago And Forbidden LoveThough Sarah Longford's days were marked by the sorrow of an ancient curse, her nights were filled with dreams of a life of privilege and passion. A life she had known in another time… and another body.Yet fate had allowed her to live again as the tempestuous Bianca, a woman who had sold herself in marriage, only to discover she had made a terrible mistake. And now it was up to her to prevent the bloodshed, and save the life of her beloved Alessio. Don't miss this fascinating tale!
The Thames has been a highway, a frontier and an attack route; it has been a playground and a sewer, a source of water and a source of power. Every stretch has its own character, atmosphere and stories. Thames: Sacred River explores the river from source to sea. Peter Ackroyd, bestselling author of London: The Biography, tells the story of the river and the people who have lived on and by it over the centuries. In part two, The Working River, we discover the wherries, barges and bridges, the industries, lawmakers and lawbreakers who form the life of the river.
Filling a niche in the geomorphology teaching market, this introductory book is built around a 12 week course in fluvial geomorphology. ‘Reading the landscape’ entails making sense of what a riverscape looks like, how it works, how it has evolved over time, and how alterations to one part of a catchment may have secondary consequences elsewhere, over different timeframes. These place-based field analyses are framed within their topographic, climatic and environmental context. Issues and principles presented in the first part of this book provide foundational understandings that underpin the approach to reading the landscape that is presented in the second half of the book. In reading the landscape, detective-style investigations and interpretations are tied to theoretical and conceptual principles to generate catchment-specific analyses of river character, behaviour and evolution, including responses to human disturbance. This book has been constructed as an introductory text on river landscapes, providing a bridge and/or companion to quantitatively-framed or modelled approaches to landscape analysis that are addressed elsewhere. Key principles outlined in the book emphasise the importance of complexity, contingency and emergence in interpreting the character, behaviour and evolution of any given system. The target audience is second and third year undergraduate students in geomorphology, hydrology, earth science and environmental science, as well as river practitioners who use geomorphic understandings to guide scientific and/or management applications. The primary focus of Kirstie and Gary’s research and teaching entails the use of geomorphic principles as a tool with which to develop coherent scientific understandings of river systems, and the application of these understandings in management practice. Kirstie and Gary are co-developers of the River Styles® Framework and Short Course that is widely used in river management, decision-making and training.
