Channel dynamics is one of the important features of the Ganga River. It has become a major concern for floodplain residents as well as for policymakers interested in riverine planning and management. The present study used remote sensing datasets for a period of about 46 years (1972 to 2018) and explored the spatial and temporal migration of the G...
Palaeo-channels are the former positions of river channels related to the geologic and climatic conditions of the past [1]. The morpho-hydrologic nature of the Sai-Ganga interfluve is very much controlled by past fluvial activities [2] that are still visible in forms of palaeo-channels and associated landforms. Studying the evolution of palaeochann...
With advances in remote-sensing technology and higher-quality products, the field of spectral indices has experienced a sizeable progressive evolution. These spectral indices computed by using different brands of remote-sensing products and applying additive, subtractive, or normalizing operations, have been and are being devised to detect diverse...
The palaeo-course of the Assi river in Uttar Pradesh, India was delineated through visual image impressions using remote sensing data. To corroborate on the existence of this palaeo-course 192 open wells and several ponds along and within the palaeo-course were observed showing very shallow groundwater table. Also, eight trenches dug within the cha...
Varanasi city has spread from its original place of origin over the natural levee into the flood basin and on to the low-level floodplain. More often the city of Varanasi suffers due to storm water logging than due to flood from the Ganga river along the bank of which it is situated. Especially during 2013 and 2016 there was large scale inundation...
Just like any other river in any part of the world, with a good number of people living
within its catchment and consequent upon the heavy industrialization, urbanization
and agriculture, lifestyle changes, other rural activities and deforestation, the Ganga
too is polluted. So is the case with Varuna and Assi rivers. Many tributaries and smaller a...
The Assi river in Varanasi, Uttar Pradesh, India, is now a small, local, ephemeral floodplain tributary of River Ganga, with a length of about 8 km and catchment area of about 22 km 2. It has also turned into a filthy drain. There are evidences in the form of palaeochannels, through patterns of water bodies and settlements along them, to suggest th...
Palaeochannels can be good possible reservoirs of groundwater and are good rechargeable aquifers. Bakulahi is a plain-fed tributary of the Sai River flowing from north-west to south-east direction with about 177-km length and about 841-km² catchment area. It emanates from interconnected series of tals (large- to medium-sized shallow depressions) si...
Accurate demarcation of river basin boundaries is an important input for any programme connected with watershed management. In the present study, the boundary of the Varuna river basin is automatically derived using coarse-and medium-resolution digital elevation models (DEMs) of SRTM-30 m, ASTER-30 m, Cartosat-30 m, ALOS Palsar-12.5 m and Cartosat-...
In the morning of 30thJuly 2014 at 07:30:00 (IST), a major part of the village Malin, located in the Western Ghats in Maharashtra was washed out and buried under a mass of mud, rock and plant debris. More than 150 peoples perished in the disaster. Primarily it was identified that extreme rainfall consecutively during 25 July to 30 July 2014 trigger...
