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.
- Describes historical and recent
trends in environmental flow
assessment
- Directly addresses practical
difficulties with applying a
scientifically informed approach in
contentious circumstances
- Serves as an effective introduction
to the relevant literature, with many
references to articles in related
scientific fields
- Pays close attention to statistical
issues such as sampling, estimation of
statistical uncertainty, and model
selection
- Includes recommendations for methods
and approaches
- Examines how methods have been
tested in the past and shows how they
should be tested today and in
the future
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.
