Course Description: Introduction to water quality and hydrodynamic modeling. Brief introduction into numerical methods to solve momentum and advective-diffusion
problems. Use of CE-QUAL-W2 (http://www.ce.pdx.edu/w2) as a teaching and modeling tool. Applications to practical water quality problems of river, lake, reservoir, and estuary
systems.

Prerequisites: Fluid mechanics, environmental engineering and upper division or graduate standing, or consent of instructor.

Assignments:
Class Modeling Project: The class will work on setting up CE-QUAL-W2 for a local water body, for example, the Kishon river including part of the Port of Haifa, Lake Kinnereth, or the Jordan River. Class members will work together on obtaining data for setting up the model.
Model Calibration Projects: The instructor will provide the class with example applications where the model needs "calibration" in order to ma tch field data. The student will complete the calibration. The student will evaluate the correctness of the model set-up and adjust model coefficients or boundary conditions as required.

Grading: Class Modeling Project (100/ 100)
4 Model Calibration Projects (50/ 50 each)
