Evaluation of Drain Quality and Nutrient Loads Management Scenarios by Using QUAL2kw Model
Environmental Monitoring and AssessmentAbstract The examination of wastewater and effluents flowing into receiving water bodies is crucial for identifying pollutant sources and implementing scenarios to reduce them. In this study, QUAL2kw was used to identify, assess, and predict the pollutant load of a drainage canal located 6 kilometers away from Anzali Wetland.
