A SIMPLE MODEL FOR DISSOLVED OXYGEN IN A STREAM: Purpose - to illustrate basic modeling concepts which can be applied to predict the movement and fate of contaminant. - Keep in mind D.O. is used as an example, but the principles can apply to any pollutant. - The equations developed are general - i.e., as applicable to reactors as they are to streams and lakes within the constraints of the simplifying assumptions we will make. We will initially consider two idealized types of systems: a. complete mix system b. plug flow system (with no mixing) [We'll deal with more complicated flow regimes later in the course] (Or a well-mixed lake) To approximate the lake To approximate the stream
