Recreational use of urban rivers is becoming popular since may act as amenity corridors with the potential for exhibition, recreation, leisure, relaxation and retreat. However, several point non-point pollution sources contribute to degradation rivers’ water quality, thereby impeding their beneficial uses amenities. The physicochemical microbiological quality a Greek river (Kifisos–Athens) was ...
The development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. Quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. As a result, an integrated multi-parameter water quality index has been developed. It is based ...
Lakes and marshes are valuable water resources and natural environments for the human beings, it is necessary to preserve and improve their water quality. Since experiencing severe pollution problems during the 1950s and 1960s, Japan has been strengthening its environmental policy. Regulations over the quality of water were enforced under the Water Pollution Control Law, resulting in the succes...

This research applied the model that simulates the effects of inflow water quality, treatment flow rate and outflow water quality on drinking water treatment plant. The model is not a physical chemistry model. However it can evaluate the performance of sedimentation process as a statistical model. The model used transfer function ARIMA model for the prediction of turbidity on sedimentation rese...
The present study aimed to calculate the water quality index (WQI) by the study of nine physico-chemical parameters on the basis of Weighted Arithmetic Index in order to assess the suitability of water for drinking purpose and other human uses in Ranebennur Taluka, Haveri District, Karnataka, India. WQI, a tool of rating water quality, is a valuable model to assess spatial and temporal changes ...
