Are there and concenrs i should lookout for when using QUALK2K as a desktop simplified modeling exercise? when I say simpliifed I mean focsing on just CBOD and ammonia, wihtout using nutrient dynamics or algae, mush like you might for a streeter-phelps model analysis. Is there any QUAL2K doumentation or literature that can referecned for this approach?

thanks,

Greg

Greg, I have attached an intro page and textbook pages scanned from Thomann & Mueller (1987). This will provide you with an example problem for 1d steady state BOD-DO-Nitrogen. I have used this problem for several years for model training courses for QUAL2K, WASP and EFDC.
