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. |

For the mass balance at the outfall, the notation of Fig. 2.9 provides the starting
point. The principal statement for the mass balance is: Mass rate of substance
upstream + mass rate added by outfall = mass rate of substance immediately ...

Therefore If t* is calculated to be less than zero, then Dc occurs at the outfall.
Equations 6.83 to 6.86 represent the DO response in a river due to a single point
source discharge of CBOD. It can be noted (Eq. 6.85) that the critical deficit (Dc)
or ...
