The Wolf Creek Research Basin project was initiated in 1992 to provide a dedicated site to carry out applied research in the Yukon sub-Arctic. The project used an ecosystem approach through contaminants, waste, water, and environment/economy integration. This report describes the Wolf Creek area, the project's objectives, the background to the project's establishment, and research activities in 1992/93, 1993/94, and 1994/95. Research projects included watershed characterization, water quality monitoring, snow and vegetation survey, streamflow monitoring, snowpack monitoring, wind redistribution of snow, snow accumulation and depletion, snowmelt, evapotranspiration, and runoff modelling.

Cryosols – permafrost – occupy a unique part of the earth and have properties greatly different from other soils. They also occur where the greatest impact of global warming is predicted. This is the first book bring together the leading researchers in the area of permafrost soils to produce a review of the geography, cryogenic soil forming processes, ecological processes, classification and use of soils that are affected by permafrost.

These proceedings contain two hundred and eighteen papers representing the work of authors from countries across the world. They cover a wide range of research and applications in safety and reliability issues that concern all types of systems, processes and structures.

This book presents decade-long advances in atmospheric research in the Mackenzie River Basin in northern Canada, which encompasses environments representative of most cold areas on Earth. Collaborative efforts have yielded knowledge entirely transferable to other high latitude regions in America, Europe and Asia. This book complements the first volume coming from the GEWEX project, dealing with the region's atmospheric dynamics.

Due to its height, density, and thickness of crown canopy; fluffy forest floor; large root system; and horizontal distribution; forest is the most distinguished type of vegetation on the earth. In the U.S., forests occupy about 30 percent of the total territory. Yet this 30 percent of land area produces about 60 percent of total surface runoff, the major water resource area of the country. Any human activity in forested areas will inevitably disturb forest floors and destroy forest canopies, consequently affecting the quantity, quality, and timing of water resources. Thoroughly updated and expanded, Forest Hydrology: An Introduction to Water and Forests, Third Edition discusses the concepts, principles, and processes of forest and forest activity impacts on the occurrence, distribution, and circulation of water and the aquatic environment. Brings water resources and forest-water relations into a single, comprehensive textbook Focuses on the concepts, processes, and general principles in forest hydrology Covers functions, properties, and science of water; water distribution; forests and precipitation, vaporization, stream flow, and stream sediment Discusses watershed management planning and practical applications of forest hydrology in resource management In a single textbook, Forest Hydrology: An Introduction to Water and Forests, Third Edition comprehensively covers water and water resources issues, forest characteristics relevant to the environment, forest impacts in the hydrological cycle, watershed research, watershed management planning, and hydrologic measurements. With the addition of new chapters, new issues, and appendices, this new edition is a valuable resource for upper-level undergraduates in forest hydrology courses as well as professionals involved in water resources management and decision-making in forested watersheds.

In March, 2004, Water Survey of Canada and the Canadian Society for Hydrological Sciences co-hosted a workshop in Yellowknife to discuss how to improve our community's abilities to predict streamflow in the Mackenzie Valley and similar cold regions of Canada. The workshop's objectives were to: 1) provide outreach to practitioners of the results of recent studies in cold water regions hydrological regimes in the context of predicting streamflow; 2) assess "state of the art" techniques to predict streamflow in ungauged basins in northern landscapes, and; 3) define technical needs and recommend a research agenda that can deliver these over the next decade. This book summarizes presentations by invited speakers on the subjects of: statisical hydrology and hydrometric network planning; cold regions hydrological processes; application of hydrological models to cold regions; and advances in distributed hydrological modelling.
