Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. This book: - Presents cutting edge thinking and assessments in forest hydrology across all latitudes and terrains, including state-of-the-art modelling techniques and methodologies - Describes the latest challenges facing forest hydrology, such as increased occurrence of disturbance, due to extreme floods, drought, disease, and fire, potentially caused by climate change - Is written by an internationally renowned team of scientists, engineers, and managers to give a well-rounded review of the subject The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

This book provides a series of exercises of various types covering matters of hydrology and watershed management. The exercises include true/false questions, multiple choice questions, and numeric, graphical, and analytical exercises. The questions draw on the basic disciplines of hydrology and physics, with some stress placed on correct or appropriate units. The questions reflect the authors' many years of teaching watershed management at undergraduate and graduate levels. Questions cover: 1. Terminology and measurement of flow (and units) 2. Quantifying stream networks 3. Concepts of water balance and evapotranspiration 4. Slope recharge, groundwater hydrology, and water-table/phreatic aquifers 5. Single and paired watershed experiments 6. Impacts of fires on watersheds 7. Concepts and measurements of water quality 8. Flooding forests 9. Valuation of water 10. Protection of forest stream by buffers 11. Urban watershed concepts The book is self-contained, and designed to be used at any time in any place, either for revision or as source material for teaching. The work is graded so that easier questions are presented early, followed by harder questions. Answers are concise but contain enough information to help students study and revise on a topic-by-topic basis. The book concludes with suggestions for student exercises and projects and is an invaluable resource for both students and instructors.

Forests cover about a third of the world's land surface area. They represent a distinct biotic community, provide a living for many millions of people, and provide fresh water to sustain communities. Forests capture part of the precipitation and pass the remainder into the soil. Some of this is then passed back to the atmosphere along with some to streams as a regulated outflow. Forest cover is generally the preferred land-use for clean water supplies, recreation, tourism, and other ecosystem benefits around the world. In many cases the value of the water exceeds the value of other forest products. The discipline "forest hydrology" was developed in the 19th and 20th Century with the aim of putting such water cycling processes into a scientific framework incorporating forest watershed management. The 21st Century has seen proliferations of new technologies that have changed society, our living environment, and this discipline. Forests are also facing unprecedented threats from land conversion, fire, drought, and the changing climate. The discipline of forest hydrology must address these issues with innovation and new ideas. The 2nd Edition of Forest Hydrology: - Presents advances of understanding of key forest hydrologic processes (particularly evapotranspiration) - Presents cutting-edge thinking and assessments in global forest hydrology, including state-of-the-art modelling and methodologies - Presents innovative findings about the impacts of forest fires on the rate of catchment formation and how past fires have led to the catchments we take for granted - Describes the latest challenges facing forest hydrology, such as increased occurrences of disturbance due to extreme precipitation and floods, drought, disease, fire, and their association with climate change - Reviews the latest perceptions of the value of forested catchments compared to alternatives such as desalination plants - Is written by an internationally renowned team of scientists, engineers, and forest managers to give a well-rounded view of the subject This book is essential reading for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

This book provides scientific evidence to underline the notion that forests offer the most reliable water catchments in the natural environment. The unique Australian ecosystem provides valuable information on the water yields and hydro-ecology of forests. Insights can be transferred to other climate zones and conditions. In this second edition, the author puts a particular focus on the most prominent challenges of our time, in relation to water management. Ground salinity, climate change, and droughts have all been newly added to this updated edition. One of the most important concepts is highlighting the accumulated contribution of smaller catchments and minor streams. Finally, readers will also get information on the economic dimension of water management. With its incisive, disciplined, and quantitative (and occasionally humorous) approach, this book helps scientists, students, and regulators to understand water-driven conflicts andoffers guidance on management.

For the last three centuries forests have been recognised as providing the best water catchments and valued for their sustained output of high quality water. In Australia, work which was commenced fifty years ago has come to fruition and is providing new information on forest hydrology issues. The book focusses on the issues of small streams, including catchment definition, slope, hydrograph formation, water quality measurement, and annual water yield. The world-wide management issues of sustaining riparian forests are examined, using the River Murray forests as an example. Finally a large amount of information is drawn together to examine the management of forested catchments for water supplies. This book presents an incisive, disciplined, quantitative approach to dealing with forest hydrology matters. Although world-wide in application, the book particularly draws on Australian studies. It is written with the needs of students and forest practitioners in mind.
