* River Self-Purification Modeling(AguaRio 2.0) is a simple numerical tool, developed based on the first order reaction of BOD (Biological Oxygen Demand) and the modified Streeter and Phelps equation, in order to determine the variations of DO (Dissolved Oxygen) and of BOD along the studied river reaches.
* The software, operated on Windows-based environment, considers various impacts of environmental factors, such as the different type of discharges (concentrated/punctual discharge source, tributary contribution and distributed discharge source), nitrogenous BOD, BOD sedimentation, photosynthetic production and benthic demand of oxygen.
* The software can be used to model the DO profile, with the aim to simulate, improve and manage the water quality and also the alternative assessment and analysis of pollutant treatment engineering.
Uses: Simulation and evaluation of water quality along 1D steady river reaches; also teaching courses relative to environment and pollutant transport.
