Book excerpt: Intended for a broad audience, this book is suitable for the science-minded layman and motivated students; it belongs in the library of anyone with more than a passing interest in the colder regions of the world. Students, permafrost specialists, and professionals in earth and environmental sciences will find most of the necessary and detailed mathematical material contained in the appendices, where it is accessible but not alarming to the less technically minded."--BOOK JACKET.

Download or read book Watershed Condition Classification Technical Guide written by U.s. Department of Agriculture Forest Service and published by Createspace Independent Pub. This book was released on 2012-08-15 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Agriculture (USDA) Strategic Plan for fiscal year (FY) 2010–2015 targets the restoration of watershed and forest health as a core management objective of the national forests and grasslands. To achieve this goal, the Forest Service, an agency of USDA, is directed to restore degraded watersheds by strategically focusing investments in watershed improvement projects and conservation practices at landscape and watershed scales. The Forest Service formed the National Watershed Condition Team and tasked it with developing a nationally consistent, science-based approach to classify the condition of all National Forest System (NFS) watersheds and to develop outcome-based performance measures for watershed restoration. The team evaluated alternative approaches for classifying watersheds (USDA Forest Service 2007) and developed the watershed condition classification (WCC) system described in this technical guide. The team designed the WCC system to—Classify the condition of all NFS watersheds; Be quantitative to the extent feasible; Rely on Geographic Information System (GIS) technology; Be cost effective; Be implementable within existing budgets; Include resource areas and activities that have a significant influence on watershed condition. National forests are required to revise the classification on an annual basis. The WCC system is a national forest-based, reconnaissance level evaluation of watershed condition achievable within existing budgets and staffing levels that can be aggregated for a national assessment of watershed condition. The WCC system offers a systematic, flexible means of classifying watersheds based on a core set of national watershed condition indicators. The system relies on professional judgment exercised by forest interdisciplinary (ID) teams, GIS data, and national databases to the extent they are available, and on written rule sets and criteria for indicators that describe the three watershed condition classes (functioning properly, functioning at risk, and impaired function). The WCC system relies on Washington Office and regional office oversight for flexible and consistent application among national forests. The WCC system is a first approximation of watershed condition, and we will revise and refine it over time. The expectation is that we will improve and refine individual resource indicators and that we will develop databases and map products to assist with future classifications. The WCC information will be incorporated into the watershed condition framework, which will ultimately be employed to establish priorities, evaluate program performance, and communicate watershed restoration successes to interested stakeholders and Congress. The watershed condition goal of the Forest Service is “to protect National Forest System watersheds by implementing practices designed to maintain or improve watershed condition, which is the foundation for sustaining ecosystems and the production of renewable natural resources, values, and benefits” (FSM 2520). U.S. Secretary of Agriculture Tom Vilsack reemphasized this policy in his “Vision for the Forest Service” when he stated that achieving restoration of watershed and forest health would be the primary management objective of the Forest Service (USDA 2010). This Watershed Condition Classification Technical Guide helps to implement this policy objective by—1. Establishing a systematic process for determining watershed condition class that all national forests can apply consistently; 2. Improving Forest Service reporting and tracking of watershed condition; 3. Strengthening the effectiveness of the Forest Service to maintain and restore the productivity and resilience of watersheds and their associated aquatic systems on NFS lands.

Download or read book Canada s Cold Environments written by Hugh M. French and published by McGill-Queen's Press - MQUP. This book was released on 1993 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low temperatures, wind-chill, snow, sea ice, and permafrost have been primary characteristics of Canada's northern and alpine environments during the past two million years. The evolution of Canada's cultural landscapes, the processes of settlement of rural areas, and the present interaction of Canadian industrial society with its biophysical environment are all deeply influenced, directly or indirectly, by the frigidity of the greater part of the country. The phenomenon of global warming, if it occurs, will lessen this coldness, but its impact on temperature extremes, sea ice regimes, vegetation, snow distribution, permafrost, glaciers, lakes, rivers, and mountain hazards are all the subject of intensive research -- the highlights of which are reviewed in Canada's Cold Environments. Eleven of Canada's leading geographers, geologists, and ecologists provide an authoritative yet readable scientific statement about the physical nature of Canada's coldness. They focus on the distinctive attributes of Canada's cold environments, their temporal and spatial variability, and the constraints that coldness places on human activity. The book is aimed at environmental scientists at all levels who need informed overviews of the substantive findings on a range of cold-related topics.

Book excerpt: The review discusses the state of thinking of each of the main national groups investigating sea ice and gives an overall appraisal of the field as a whole. Emphasis is placed on (1) the physical basis for interpreting sea ice strength (phase relations, air volume, and structural considerations), (2) theoretical considerations (strength models, air bubbles and salt reinforcement, and interrelations between growth conditions and strength), (3) experimental results (tensile, flexural, shear, and compressive strength, elastic modulus, shear modulus and Poisson's ratio, time dependent effects, and creep), and (4) plate characteristics. The paper includes a review of problems in sea ice investigations, relates the chemical, crystallographic, mechanical, and physical aspects involved, and concludes by showing how to utilize this knowledge to solve practical problems.
