Provides critiques of current practices for environmental flow assessment and shows how they can be improved, using case studies. 

In Environmental Flow Assessment: Methods and Applications, four leading experts critique methods used to manage flows in regulated streams and rivers to balance environmental (instream) and out-of-stream uses of water. Intended for managers as well as practitioners, the book dissects the shortcomings of commonly used approaches, and offers practical advice for selecting and implementing better ones. 

The authors argue that methods for environmental flow assessment (EFA) can be defensible as well as practicable only if they squarely address uncertainty, and provide guidance for doing so. Introductory chapters describe the scientific and social reasons that EFA is hard, and provide a brief history. Because management of regulated streams starts with understanding freshwater ecosystems, Environmental Flow Assessment: Methods and Applications includes chapters on flow and organisms in streams. The following chapters assess standard and emerging methods, how they should be tested, and how they should (or should not) be applied. The book concludes with practical recommendations for implementing environmental flow assessment.

Environmental Flow Assessment: Methods and Applications is an excellent book for biologists and specialists in allied fields such as engineering, ecology, fluvial geomorphology, environmental planning, landscape architecture, along with river managers and decision makers.

Athletes are dependent upon a constant supply of accurate and reliable information from the environment whilst performing complex movements.

Visual Perception and Action in Sport examines the information which is perceived by the human visual system and the way it is utilised to support actions in sport. It focuses attention on the rich diversity of sport-related studies drawn together from a number of theoretical approaches. Divided into three sections, this book covers:

* indirect theories of perception and action* direct theories of perception and action* skill acquisition in the sports context.

Each of the sections features learning objectives, summary, and study questions to help facilitate student learning. Throughout the text, the integration of theoretical knowledge and practical expertise is emphasised.

All three authors are specialists have expertise in the teaching and researching of motor learning and control in sport.
