This paper proposes an integrated framework of remote sensing and machine-learning techniques to predict municipal wastewater influent biochemical oxygen demand (BOD5) in treatment plants (WWTPs). The study compares the performance several supervised algorithms, specifically decision tree, random forest, adaptive boosting, gradient boost, extreme boosting against received by two WWTPs South Kin...

The Beshar River is one of the most important aquatic ecosystems in the upstream of the Karun watershed in south of Iran which is affected by point and non point pollutant sources . This study was done in order to evaluate the effects of pollutants activities on the water quality of the Beshar river and its aquatic ecosystems. This river is approximately 190 km in length and situated at the geo...
