About the book:


The hydraulic engineering is nowadays more and more branching into two complementary professions - "hydro-informatics specialists" who are deve-loping numerical methods and crea-ting complex computer codes, and "hydraulic engineers" who are solving practical problems. As a consequence, the former professionals are more and more lacking the opportunity of practical experience, while the latter ones are becoming increasingly defi-cient in theoretical knowledge. This book by prof. M. Jovanovic has the quality to equally address both cate-gories of river engineering experts: to present and future "hydroinformatics people" it gives the rationale behind the technical task to be accomplished, while to the "practicing engineers" it clarifies theoretical principles behind numerical methods used in hydro-informatics. This approach is not only significant at the present moment, but will certainly became crucial in the years to come...
