Piggyback basins developed at the mountain fronts of collisional orogens can act as important, and transient, sediment stores along major river systems. It is not clear, however, how the storage and release of sediment in ...
Sensitivity of drainage morphometry based hydrological response (GIUH) of a river basin to the spatial resolution of DEM data

Sahoo, Ramendra; Jain, Vikrant (Elsevier, 2018-02)

Drainage network pattern and its associated morphometric ratios are some of the important plan form attributes of a drainage basin. Extraction of these attributes for any basin is usually done by spatial analysis of the ...
Seven 21st century challenges of arsenic-fluoride contamination and remediation

Maity, Jyoti Prakash; Vithanage, Meththika; Kumar, Manish; Ghosh, Ashok; Mohan, Dinesh; Ahmad, Arslan; Bhattacharya, Prosun (Elsevier, 2021-02)

Arsenic (As) and Fluoride (F) are two commonly occurring geogenic contaminants in groundwater environment, causing a range of carcinogenic and non-carcinogenic adverse health effects worldwide. Several studies have been ...
Simulating the gas hydrate behavior at equilibrium dissociation: a study from Mahanadi basin of eastern offshore, India

Ghosal, Dibakar; Ganguli, Shib Sankar; Singh, Rishi N.; Sain, Kalachand (Elsevier, 2018-12)

A suitable model is developed by analyzing the effects of external stimuli such as changes in pressure and temperature on the gas production behavior for the multi-phase fluid system. Our ultimate goal was to assess and ...
Simultaneous removal of Cong red and Cr (VI) in aqueous solution by using Mn powder extracted from battery waste solution

Kumari, Deepa; Mazumder, Payal; Kumar, Manish; Deka, Jyoti Prakash; Shim, Jaehong (Elsevier, 2018-09)

Adsorption capacity of manganese powder synthesized from spent battery waste solution was analyzed for simultaneous removal of congo red and hexavalent chromium. Manganese powder was synthesized by heat treatment followed ...
Spatio-temporal variability in stream power distribution in the upper Kosi river basin, central Himalaya: controls and geomorphic implications

Kaushal, Rahul K.; Sarkar, Ankita; Mishra, Kanchan; Sinha, Rajiv; Nepal, Santosh; Jain, Vikrant (Elsevier, 2019-10)

River processes in a drainage basin are strongly governed by spatio-temporal variability in stream power. Recently, various approaches have been developed to derive the spatial variability of stream power in a river basin; ...
Spatiotemporal variability of Neotectonic activity along the Southern Himalayan front: a geomorphic perspective

Dey, Saptarshi; Kaushal, Rahul Kumar; Sonam; Jain, Vikrant (Elsevier, 2018-09)

The Sub-Himalaya is arguably consuming ~100% of the total Himalayan shortening since early Quaternary. We compiled geodetic shortening rates, paleoseismic events (historical earthquakes), shortening rates deduced from ...
Structural variations in basal decollement and internal deformation of the Lesser Himalayan duplex trigger landscape morphology in NW Himalayan interiors

Dey, Saptarshi; Thiede, Rasmus; Biswas, Arindam; Chakravarti, Pritha; Jain, Vikrant (European Geosciences Union, 2020-06)

The Kishtwar Window (KW) of the NW Himalaya exposes the northwestern termination of the orogen-parallel anticlinal stack of thrust nappes, termed as the Lesser Himalayan Duplex and its evolution portrays rapid exhumation ...
Study of morphology and degradation of lunar craters using Chandrayaan–1 data

Agarwal, Nikita; Haridas, Athira; Khanna, Nitin; Srivastava, Pradeep; Jain, Vikrant (Elsevier, 2019-03)

Impact craters are essential and dominant features of the lunar surface. Under the presence of a very thin atmosphere, the degradation of the lunar craters takes place possibly due to gravity, slope processes, or solar ...
Sustainable removal of pernicious arsenic and cadmium by a novel composite of MnO2 impregnated alginate beads: A cost-effective approach for wastewater treatment

Shim, Jaehong; Kumar, Manish; Mukherjee, Santanu; Goswami, Ritusmita (ScienceDirect, 2019-03)

There is a dire necessity of developing low cost waste water treatment systems, for the efficient removal of noxious heavy metals (and metalloids) such as Arsenic (As) and Cadmium (Cd). Magnetic biopolymer (CABs-MO) was ...
Temporal profiling of uplift rate along an active fault using river long profile in the Kuchchh region, Western India

Sonam; Sahoo, Ramendra; Singh, Rishi Narain; Jain, Vikrant (Elsevier, 2020-11)
