Lateral migration of the Bhagirathi River temporally creates unavoidable geomorphic hazards in West Bengal, India. The Bhagirathi River flows SW for ~67.30 km between the confluence point of Ajay and Jalangi rivers in East Burdwan and Nadia districts of West Bengal. The course of Bhagirathi is notably migration prone and cultivates problematic changes along its course over time. In the study, we have looked into its migration tendency and unpredictability for past 238 years and then predicted the lateral shifting of river centerline using temporal satellite imageries
The study was carried out to assess some physico-chemical water quality parameters and pollution scenario of the Ichamati river. Water samples were collected from nine different selected stations at origin of the river Majhdia to Taki end portion of the Ichamati river during the pre-monsoon, monsoon and post-monsoon periods. A seasonal variation in these parameters was observed throughout the study period and monthly comparisons were made as monsoon, pre-monsoon and post-monsoon. The results of the present investigation was undertaken to asses seasonal and spatial variation in pH, Electrical Conductivity, Turbidity, Salinity, Chlorophyll, DO and Water Temperature are compared with literature values and investigation reveals that there is a fluctuation in the physico-chemical characters of the water, this will be due to ebb and flow and change in the temperature and salinity as season changes. All parameters except turbidity and conductivity have shown high concentration in pre-monsoonmonsoon and post-monsoon, overall the concentration of water quality parameters were governed by flushing of rainfall, river water flow, sea water intrusion runoff from agricultural fields. Turbidity content in the study area was higher because the Ichamati river is dynamic zone of lower stretch. This river only depends on upper stretch rainy season rain water; no tidal fluctuation but lower stretch of the river is high tidal fluctuation the salinity is must high then upper stretch the value of Salinity 3-8.5 ppm that the parallely fluctuation the huge amount of sediment continuing; the turbidity is very high 600-700 NTU.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
