The main objective of the Water Framework Directive in the European
countries is to achieve a "good status" of all the water bodies, in
the integrated management of river basins. In order to assess the
impact of improvement measures, water quality models are necessary.
During the previous decades the progress in computer technology and
computational methods has supported the development of advanced
mathematical models for pollutant transport in rivers and streams.
This book is intended to provide the fundamental knowledge needed
for a deeper understanding of these models and the development of
new ones, which will fulfil future quality requirements in water
resources management. This book focuses on the fundamentals of
computational techniques required in water quality modelling.
Advection, dispersion and concentrated sources or sinks of
contaminants lead to the formulation of the fundamental
differential equation of pollutant transport. Its integration,
according to appropriate initial and boundary conditions and with
the knowledge of the velocity field, allows for pollutant behaviour
to be assessed in the entire water body. An analytical integration
is convenient only in one-dimensional approach with considerable
simplification. Integration in the numerical field is useful for
taking into account particular aspects of water body and
pollutants. To ensure their reliability, the models require
accurate calibration and validation, based on proper data, taken
from direct measurements. In addition, sensitivity and uncertainty
analysis are also of utmost importance. All the above items are
discussed in detail in the 21 chapters of the book, which is
written in a didactic form for professionals and students.
