| description abstract | QUAL II, a stream model developed for the U.S. Environmental Protection Agency integrates a set of simultaneous differential equations representing the evolution of certain constituents over time. It is shown that whenever the concentration of any of the critical growth elements in the algae kinetics process is set equal to zero, QUAL II cannot operate as such as singularity problems arise. Because the model runs under those conditions it appears that by-passes in the program are used to avoid these problems. These corrective measures are only necessary due to a poor representation of the NO | |
