Mathematical Modelling of Water Quality and Engineering of Pili River Stream in Nagpur District of Maharashtra

Abstract

The working plan deals with the preliminary proposal for mathematical modelling of water quality and engineering of Pili River stream located in Nagpur District of Maharashtra (India). The total length of Pili River within the city is about 16.7 Kilometres. Its width varies from 20-40 meters and depth ranges from 2 to 4.5 meters. There has been growing concern for maintenance of water quality and ecosystem along Pili River at both Legislative and Judiciary levels. Therefore it is need of the day to rejuvenate its water quality and habitat. Urbanization had created ecological threat due to immense dumping of domestic wastewater. General background information about natural characteristics of the selected stations along the Pili River and main source of pollution was made for a better understanding of this problem. The calculation was divided into three stages, and the problem was solved using the so-called “combined catch-up / feedback method”. Computer memory space is saved as well as calculations speeds up using this method. The complicated hydraulic conditions in stream networks make it very difficult to estimate parameters. While the present developed model can be used for varied stream networks, it is necessary to estimate the parameters of the model according to the local measurements.
