This series of five volumes proposes an integrated description ofphysical processes modeling used by scientific disciplines frommeteorology to coastal morphodynamics. Volume 1 describes thephysical processes and identifies the main measurement devices usedto measure the main parameters that are indispensable to implementall these simulation tools. Volume 2 presents the differenttheories in an integrated approach: mathematical models as well asconceptual models, used by all disciplines to represent theseprocesses. Volume 3 identifies the main numerical methods used inall these scientific fields to translate mathematical models intonumerical tools. Volume 4 is composed of a series of case studies,dedicated to practical applications of these tools in engineeringproblems. To complete this presentation, volume 5 identifies anddescribes the modeling software in each discipline.
