## Principles of surface water quality modeling and controlThis book teaches the fundamentals and principles which underlie the mathematical modeling techniques used to analyze the quality of surface waters. The text first provides an overview of the different bodies of water in which water quality problems need to be addressed before examining specific problems that occur across all bodies of water. |
