Abstract This paper aims to assess the requirement of load reductions and flow augmentation enhance assimilation yield Yamuna River, Delhi. The framework QUAL2kw was used predict river quality. model calibrated confirmed in critical conditions pre-monsoon periods. Three strategies were established for varying pollutant loads. dissolved oxygen (DO) concentration predicted with changing biochemic...

Abstract The variations in pH and Dissolve Oxygen (DO) concentrations were analysed surface river water samples for three seasons Pre-Monsoon, Monsoon Autumn (January to December 2022) four major rivers Ganga, Yamuna, Gomti Hindon flowing through Uttar Pradesh, India. For Ganga range varied from 7.65 8.47 DO 6.4mg/l 9.26mg/l. Yamuna 7.31 10.5 0 8.1mg/l. showed, between 7.2 8.48, while 0.63mg/l ...

The formation and occurrence of urban heat island (UHI) is a result of rapid urbanization and associated concretization. Due to intensification of heat combined with high pollution levels, urban areas expose humans to unexpected health risks. In this context, the study aims at comparing the UHI in the two largest metropolitan cities of India, i.e., Delhi and Mumbai. The presence of surface UHI ...

Identification of the precise nature and attributes of the time series of climatological data is very important and is usually the first step for water resources planning and management. Such exercise is very important for hydro-climatic extremes. In many instances, a climatic time series is generally not statistically independent but is comprised of patterns of persistence, cycles, trends or s...

RAPD was used to delineate the hilsa populations sampled from the Ganga, Yamuna, Hooghly, and Narmada Rivers at six different locations. Six degenerate primers were used to generate the fragment patterns from the samples collected. All primers were highly polymorphic and generated high numbers of amplification products. Nei's genetic distances were calculated between locations. The overall aver...

 In contrast to existing trends and expected deteriorating water quality in the river Yamuna in Delhi which carries potential cultural economical and health importance, March 2016 water data showing improvement despite large public gathering at river bank during Cultural Festival. The reasons and factors were investigated. The paper presents the test reports of eco- enzyme which was found to be...
