Schnoor Wiley-Interscience, New York, 1996 ISBN: 0-471-12436-2 COURSE OBJECTIVES: The modeling of flow and contaminant transport in river systems has long been an important challenge for the civil and environmental engineering community. Considering the complications regarding not only the underlying physical background but also the mathematical difficulties with respect to its numerical solution, this topic is currently one of the most active research areas of the community. The stringent regulations for the preservation of river water quality necessitates that these systems are fully understood and managed. Thus, modeling the river ecosystem has become an important objective of all management plans developed in the last few decades. Based on these fundamentals, this course is intended to provide the graduate student with an advanced level of understanding for modeling water quality in rivers. Having completed this course, the students are expected to know the fundamentals of flow and contaminant transport in rivers from a particular point of view of distributed modeling concepts and are further expected to complete a modeling task from start to finish for any river system. Finally, the course is also intended to provide the details of the commonly used modeling software including but not limited to QUAL2EU, CEQUAL-RIV1 and MIKE group of models. IV.

To teach the student the details of flow and contaminant transport modeling in rivers. 2. To establish a solid foundation such that a student could develop a water quality model of a river from start to finish. 3. To introduce students to the numerical solution procedures of commonly used models. Contents: The course starts with an introduction to flow and contaminant transport modeling in river systems. Within this context, the fundamentals of the hydraulics of flow and the transport of contaminants in rivers are discussed. The constituent reactions and interrelations are given together with dimensionality concepts of typical river models. The course then presents the numerical solution procedures and algorithms for flow and contaminant transport modeling. Finally, the course introduces several computer models that are commonly used for modeling river systems. TEACHING AND LEARNING METHODS The course is taught in standard lecture format with class presentation and discussions. All class members are expected to attend the courses, prepare and present a term project. TEXTBOOK None ASSESSMENT Term project Midterm exam Final exam
