Abstract: Streamwater quality is affected by a number of natural and human processes. Major types of chemical compounds which may affect water quality include nutrients (nitrogen and phosphorus). Nutrients are of particular interest in the study of environmental quality within the Pusiano/Lambro River basin as they turn out to be critical for the water quality in the lake. This paper briefly details a methodological approach used for implementation of water quality models, with an aim of defining water quality in the lake’s immissary as a result of all different pollution-generating activities within the basin. A steady-state simulation model (QUAL2E) was adopetd to predict changes in the concentration of in-stream nutrient concentrations in the Lambro River within the Lake Pusiano watershed (Northern Italy). Simulation of local hydrology as a preliminary study was conducted using the HEC-HMS model. In this study, watershed analysis is carried out with the “Soil and Water Assessment Tool” (SWAT) package. This paper describes therefore parts of an integrated hydrologic, catchment and stream nutrient modelling system. The river modelling system is designed to simulate at first, and subsequently to develop reduction plans, nutrient loads delivered to lake.
