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 subjectThis 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.
