Ebook: Water Quality Modelling for Rivers and Streams

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.  Read more...
