Rivers play an imperative role in the development of nation and sustenance of life, which are being polluted due to acquisitive nature of human. Hydrobiology of river Ramganga from Kalagarh (upstream) to Moradabad city (down stream) also known as Brass city , have studied for three years. Spatio-temporal variations in several physico-chemical parameters, ichthyodiversity and fishing activities in the river were undertaken. The study exploring that the downstream of the river were heavily polluted due to excessive discharge of untreated industrial effluent containing heavy metals. The fish diversity includes total 26 species belonging to 9 families. Decreasing trend in the species richness was observed when moving to downstream which was related to less DO content and high load of pollution in the river. On the basis of Water Quality Index (WQI) the river was classified into permissible, slight, moderate and heavily polluted.Multivariate statistical methods were used for interpretations of hydrochemical parameters. The book would be of interest to Academicians,Aquatic Scientists, Researchers,Water works department,fishery department, Planners and Policy makers of river basin.
The research presents water quality analysis of Bhadravathi in Karnataka State, India. Fourteen physico-chemical and biological parameters were considered for the analysis. The raster maps created using GIS are used to represent the spatial distribution of the parameters for both pre and post-monsoon seasons. Using physico-chemical parameters, Water Quality Index (WQI) was determined. The WQI shows 11% of the surface water samples fall under very good category during pre-monsoon and 78% in post-monsoon. The water sample at New Bridge site shows sign of pollution throughout year with WQI in the range 50-100 and hence unfit for use. In groundwater samples, 20% of samples in the pre-monsoon and 50% samples during post-monsoon fall under good quality. 50% of water samples during pre-monsoon and 60% of samples during post-monsoon fall under good category and water sample at Haladamma temple are found unfit. Further, QUAL2K model predicted the DO and BOD values considerably well along the Bhadra River from Lakkavalli to Bhadravathi Town. However, the Streeter Phelp s model estimated higher DO as compared to QUAL2K model. This is due to provision of outfall effect in Streeter Phelp s model.
Surface water ecosystems are complex with interlinked physical, chemical and biological systems. Day to day activities of Human causes changes in these attributes thus affecting the aquatic living resources over time. In the case of fresh water resources, municipal sewage, agricultural run-off and industrial effluents gets discharged into streams, lakes and rivers thereby making these water resources unsuitable for drinking purpose. Since water is a universal solvent, most of the pollutants get dissolved easily which degrades the overall surface water quality. Therefore, it is necessary to conduct periodic monitoring of water resource. It not only helps in recording the levels of various pollutants in water bodies but also help policymakers, government bodies to formulate policies that can help protect the human health and the environment.
The degree of treatment or treatment efficiency of wastewater treatment plant depends primarily on the condition and best usage of the receiving stream. Work is carried out here for a city which is one of the highly industrialized cities and has number of small and medium scale textile units scattered all over the city. This city has waste water treatment plant which treats the waste water and dispose the effluent in the river. Last few years the river is facing lot of pollution problems. It is necessary to study the river assimilation capacity, possible modifications to the treatment efficiency of waste water treatment plant by studying river pollution parameters. Computer programming shall be used to study the effect of different parameters on pollution treatment efficiency. Present book deals with one of such approach, prime aim of which is having to find the sensitivity of river pollution parameters. This book also involves calculating Water Quality Index (wqi) of the river water.
