This book was released on 2010 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the results of a project done to assess the potential for impacts and changes to the peak-flow regime throughout various sub-basins of the Fraser River Watershed. The vast size and the physical complexity of the Fraser River Basin make it extremely difficult to directly measure the hydrologic effects of beetle kill and salvage harvesting. As a result, a hydrology model has been used to assess the hydrologic consequences of the current outbreak. The project is part of a larger effort in quantifying the water resource impacts of the pine beetle and salvage harvesting across a range of watershed scales.--Includes text from document.

Download or read book Forest Hydrology and Watershed written by Fan-Rui Meng and published by MDPI. This book was released on 2019-08-20 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrological processes in forested watersheds are influenced by environmental, physiological, and biometric factors such as precipitation, radiation, temperature, species type, leaf area, and extent and structure of forest ecosystems. Over the past two centuries, forest coverage and forest structures have been impacted globally by anthropogenic activities, for example, forest harvesting, and conversion of forested landscapes for plantations and urbanization. In addition, since the industrial revolution, climate change has resulted in profound impacts on forest ecosystems due to higher carbon dioxide (CO2) concentration or CO2 fertilization, warmer temperatures, changes in frequency and intensity of extreme weather events and natural disturbances. As a result, hydrological processes in forested watersheds have been altered by these natural and anthropogenic factors and these changes are expected to accelerate due to future changing climatic conditions. Hence, understanding how various environmental, physiological, and physical drivers interactively influence hydrological and biogeochemical processes in forest ecosystems is critical for sustainable water supply in forested watersheds. About 21% of the global population depends on water sources that originate in forested catchments where forest coverage larger than 30%. Furthermore, there are knowledge gaps in our understanding of the mechanism of hydrological and hydrochemical cycles in forested watersheds. This Special Issue addresses these gaps in our knowledge and includes twelve papers in the following three major research themes in forest watershed areas.
Download or read book Management of Mountain Watersheds written by Josef Krecek and published by Springer Science & Business Media. This book was released on 2012-04-24 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book aims to address the interdisciplinary targets of watershed management in mountain regions based on the current knowledge of the subject. The focus of the book is particularly on monitoring, research, and modelling the interactions between the climate, water cycle, and aquatic ecosystem. The issues of watershed management in mountain regions in different parts of Europe, Africa, America and Asia have been the central theme of the book, which is basically divided into five sections: Institutional aspects in control of mountain regions; Stream-flow processes in mountain catchments; Water chemistry and biota in mountain streams and lakes; Effects of forest practices and climate change on hydrological phenomena; and Soil conservation and control of floods and landslides. The contributions have been peer-reviewed and the interdisciplinary team of authors includes experts from the specialised areas of geography, hydrology, chemistry, biology, forestry, ecology, economy and sociology. The practical applications and management strategies mentioned in the book, deal with the integrated resource management approach, based on the compromise between the development, conservation/ protection of the nature. Finally, the socio-economic and cultural aspects, and ecosystem prevalent in a mountain catchment are discussed in detail.
Download or read book Mountain Pine Beetle written by Fred L. Bunnell and published by . This book was released on 2011 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a synthesis of recently completed studies to assess the ecological consequences of forest management after attack by mountain pine beetle or other large-scale disturbances. Studies are assessed for their contributions to gaps in knowledge previously identified in the Mountain Pine Beetle Initiative Working Paper "Evaluating effects of large scale salvage logging for mountain pine beetle on terrestrial and aquatic vertebrates," which was published in 2004. This report focuses on studies developed through the federal Mountain Pine Beetle Initiative, the federal Mountain Pine Beetle Program, and the complementary BC Forest Science Program. Relevant information from other jurisdictions is sometimes included to augment those studies. Topics examined are: the impacts of beetle kill and salvage operations on habitat attributes; the impacts of beetle kill and salvage operations on attendant processes, such as snag fall rates, light interception, and snow accumulation; and the wildlife response to large-scale beetle outbreaks and management strategies. For each of these three topics, we provide a summary of: research to date; pertinent findings to date; and gaps in research.
Download or read book A Synthesis of the Hydrological Consequences of Large scale Mountain Pine Beetle Disturbance written by Markus Schnorbus and published by . This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current synthesis is a review of research examining the effects of large-scale mountain pine beetle (MPB)-related disturbance conducted predominantly over the past five years. The emphasis is on research that explicitly examines the impact of beetle kill (or biotic disturbance in general) and the cumulative effects of large scale salvage harvesting operations in response to beetle kill. In general, forest disturbance has been found to increase snow accumulation and melt, reduce interception loss and evaporation, and increase runoff and stream flow.--Document.

This book was released on 2009 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was developed to identify a set of risk indicators to predict the risk of summer-ground loss at the watershed level within the Vanderhoof Forest District (VFD) and others, subsequent to the mountain pine beetle (MPB) infestation of lodgepole pine stands. This report was done in relation to the VFD annual cut of stands, and the following difficultings that operators found in running their equipment in wet versus dry soils in harvest years. Risk indicators were selected from available GIS information, aerial photographs, and local knowledge. The most effective indicators for predicting the risk of wet-ground areas at the watershed level were found to be lodgepole pine content, understorey, drainage density, sensitive soils, and the topographic index, all of whose values are available from provincial databases. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.

This book was released on 2009 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The epicentre of the mountain pine beetle (MPB) outbreak at this time is in the Fraser River drainage basin in British Columbia. Due to the infestation's area and associated salvage harvest options, the potential exists for widespread and significant local and regional hydrologic impacts within the basin. The main objective of this paper is to estimate impacts from land-cover change on average peak flows for all third-order (1:50,000) watersheds in British Columbia because peak flows are a major concern for flood hazard, erosion and sedimentation impacts, and other hydrologic consequences. The goal is to provide a model that can be applied to all watersheds and, in particular, ungauged basins throughout the province.--Includes text from document and publisher's website.
