Surface Water Resources Assessment and Planning with the QUAL2KW Model : A Case Study of the Maroon and Jarahi Basin (Iran)
Mathematical models are useful for predicting the reactions of watercourses such as rivers due to the entry of contaminants. Some of these models are able to simulate the effects of present and future loadings as well as aid managers and officials in making decisions even if the data are sparse. In other words, river water quality preservation requires more investment in wastewater treatment and/o
