Book Description
Once-monthly streamflow measurements were used to estimate long-term mean annual flow, mean monthly flow, and various points on the flow-duration curve for 72 sites in the mountainous areas of western Montana. The estimated flow characteristics at 56 measurement sites, together with data from 22 gaging stations, were used to develop maps showing the variability of mean annual runoff, in inches, for three areas.

Book Description
Successful management of water in mountain streams by the USDA Forest Service requires that the link between resource development and channel change be documented and quantified. The characteristics of that linkage are unclear in mountain streams, and the adjustability of these streams to land-use and hydrologic change has been argued in court. One way to quantify the adjustability of a stream is to examine its geomorphic history. An excellent source of historic geomorphic data are the records associated with stream gaging stations maintained by the U.S. Geological Survey. This report describes what records are available, how to organize the data on computer spreadsheets, and discusses 6 techniques that quantify the spatial and temporal magnitude of historic channel adjustments. The discharge measurements include physical measurements of the channel. In particular, USGS discharge measurements include physical measurements of the channel. By analyzing these measurements collectively, it is possible to quantify monthly, annual, and decadal scales of adjustment. Once the history of channel adjustment is determined, it can be compared to histories of climate change, flow regulation, and land use. These comparisons may link the geomorphic adjustments to particular patterns, events, or activities. Resource managers can use this knowledge to better assess the ramifications of resource development, land use, and restoration efforts on mountain stream systems.

Book Description
Since the publication of the first edition (1994) there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals. Stream Hydrology: An Introduction for Ecologists Second Edition documents recent research and practice in these areas. Chapters provide information on sampling, field techniques, stream analysis, the hydrodynamics of moving water, channel form, sediment transport and commonly used statistical methods such as flow duration and flood frequency analysis. Methods are presented from engineering hydrology, fluvial geomorphology and hydraulics with examples of their biological implications. This book demonstrates how these fields are linked and utilised in modern, scientific river management. * Emphasis on applications, from collecting and analysing field measurements to using data and tools in stream management. * Updated to include new sections on environmental flows, rehabilitation, measuring stream health and stream classification. * Critical reviews of the successes and failures of implementation. * Revised and updated windows-based AQUAPAK software. This book is essential reading for 2nd/3rd year undergraduates and postgraduates of hydrology, stream ecology and fisheries science in Departments of Physical Geography, Biology, Environmental Science, Landscape Ecology, Environmental Engineering and Limnology. It would be valuable reading for professionals working in stream ecology, fisheries science and habitat management, environmental consultants and engineers.

Book Description
A bedload trap is a portable sampler designed specifically for collecting gravel and cobble bedload (4 to 180 mm in diameter) in wadeable streams. Bedload traps consist of an aluminum frame with a 12 by 8 inch (0.3 by 0.2 m) opening to which a 3- to 5.5-ft (0.9 to 1.65 m) long trailing net is attached. Bedload traps are installed on ground plates that are anchored to the stream bottom with metal stakes. Traps do not have to be hand-held while sampling and have a large volumetric capacity. This permits collection of bedload over relatively long intervals, typically one hour per sample. In this document, we provide detailed guidelines for bedload trap construction and operation. We describe component parts and offer instructions for making the nets and assembling the sampler. Appropriate site selection and preparation are discussed as well as bedload trap installation, use, and maintenance. These guidelines also show how to process the collected bedload samples in the field and how to perform some of the typical calculations used in bedload evaluation.

Book Description
Mountains cover a quarter of the Earth’s land surface and a quarter of the global population lives in or adjacent to these areas. The global importance of mountains is recognized particularly because they provide critical resources, such as water, food and wood; contain high levels of biological and cultural diversity; and are often places for tourism and recreation and/or of sacred significance. This major revision of Larry Price’s book Mountains and Man (1981) is both timely and highly appropriate. The past three decades have been a period of remarkable progress in our understanding of mountains from an academic point of view. Of even greater importance is that society at large now realizes that mountains and the people who reside in them are not isolated from the mainstream of world affairs, but are vital if we are to achieve an environmentally sustainable future. Mountain Geography is a comprehensive resource that gives readers an in-depth understanding of the geographical processes occurring in the world’s mountains and the overall impact of these regions on culture and society as a whole. The volume begins with an introduction to how mountains are defined, followed by a comprehensive treatment of their physical geography: origins, climatology, snow and ice, landforms and geomorphic processes, soils, vegetation, and wildlife. The concluding chapters provide an introduction to the human geography of mountains: attitudes toward mountains, people living in mountain regions and their livelihoods and interactions within dynamic environments, the diverse types of mountain agriculture, and the challenges of sustainable mountain development.

Book Description
A hugely important text for advanced undergraduates as well as graduates with an interest in stream and river ecology, this second, updated edition is designed to serve as a textbook as well as a working reference for specialists in stream ecology and related fields. The book presents vital new findings on human impacts, and new work in pollution control, flow management, restoration and conservation planning that point to practical solutions. All told, the book is expanded in length by some twenty-five percent, and includes hundreds of figures, most of them new.
