In recent years, the adequacy of collected water quality data and
the performance of existing monitoring networks have been seriously
evaluated for two basic reasons. First, an efficient information
system is required to satisfy the needs of water quality management
plans and to aid in the decision-making process. Second, this
system has to be realized under the constraints of limited
financial resources, sampling and analysis facilities, and
manpower. Problems observed in available data and shortcomings of
current networks have led researchers to focus more critically on
the design procedures used. The book is intended to present an
up-to-date overview of the current network design procedures and
develop basic guidelines to be followed in both the design and the
redesign of water quality monitoring networks. The book treats the
network design problem in a comprehensive and systematic framework,
starting with objectives of monitoring and elaborating on various
technical design features, e.g. selection of sampling sites,
sampling frequencies, variables to be monitored, and sampling
duration. The design procedures presented are those that the
authors have recently applied in a number of national and
international projects on the design and redesign of water quality
monitoring networks. Thus, the book covers real case studies where
not only the methods described in the earlier titles are used but
also new techniques are introduced. Where earlier methods are used,
they are assessed with respect to their efficiency and
applicability to real case problems. Audience: Essentially, the
framework adopted in the book applies as well to other hydrometric
data collection networks besides those of water quality. In this
respect, it is expected that planners, designers, scientists, and
engineers who are involved in hydrometric network design will
benefit from the in-depth approach assumed in this book. It will
also be of interest to research and data centers, international
programs and organizations related to environmental monitoring. The
book may also be used as a reference text in graduate courses of
water resources and environmental engineering programs.
This book presents the proceedings and the outcomes of the NATO
Advanced Research Workshop (ARW) on Integrated Technologies for
Environmental Monitoring and Information Production, which was held
in Marmaris, Turkey, between September 10- 14, 200 I. With the
contribution of 45 experts from 20 different countries, the ARW has
provided the opportunity to resolve the basic conflicts that tend
to arise between different disciplines associated with
environmental data management and to promote understanding between
experts on an international and multidisciplinary basis. The
prevailing universal problem in environmental data management (EDM)
systems is the significant incoherence between data collection
procedures and the retrieval of information required by the users.
This indicates the presence of problems still encountered in the
realization of; (1) delineation of objectives, constraints,
institutional aspects of EDM; (2) design of data collection
networks; (3) statistical sampling; (4) physical sampling and
presentation of data; (5) data processing and environmental
databases; (6) reliability of data; (7) data analysis and transfer
of data into information; and (8) data accessibility and data
exchange at local, regional and global scales. Further problems
stem from the lack of coherence between different disciplines
involved in EDM, lack of coordination between responsible agencies
on a country basis, and lack of coordination on an international
level regarding the basic problems and relevant solutions that
should be sought.
