Quaternary tectonic control on channel morphology over sedimentary low land:A case study in the Ajay-Damodar interfluve of Eastern India

Geoscience Frontiers 2015年第6期6卷 927-946页

作者： Suvendu Roy abhay Sankar Sahu Department of Geography University of Kalyani

The style of active tectonic on the deformation and characterization of fluvial landscape has been investigated on three typical skrike-slip fault zones of the Ajay-Damodar Interfluve（ADI） in Eastern India through field mapping,structural analysis and examination of digital topography（ASTER-30 m）,multispectral imageries,and Google Earth images,Channel morphology in Quaternary sediment is more deformed than Cenozoic lateritic tract and igneous rock system by the neotectonic activities,The structural and lithological controls on the river system in ADI region are reflected by distinct drainage patterns,abrupt change in flow direction,offset river channels,straight river lines,ponded river channel,marshy lands,sag ponds,palaeo-channels,alluvial fans,meander cutoffs,multi-terrace river valley,incised compressed meander,convexity of channel bed slope and knick points in longitudinal profile,Seven morphotectonic indices have been used to infer the role of neotectonic on the modification of channel morphology,A tectonic index map for the ADI region has been prepared by the integration of used morphotectonic indices,which is also calibrated by Bouguer gravity anomaly data and field investigation.

Effectiveness of basin morphometry, remote sensing, and applied geosciences on groundwater recharge potential mapping： a comparative study within a small watershed

引用

Frontiers of Earth Science 2016年第2期10卷 274-291页

作者： Suvendu ROY abhay Sankar SAHU Department of Geography University of Kalyani Kalyani Nadia-741235 West Bengal India

A multidisciplinary approach using the inte- grated field of geosciences （e.g., geomorphology, geotec- tonics, geophysics, and hydrology） is established to conduct groundwater recharge potential mapping of the Kunur River Basin, India. The relative mean error （RME） calculation of the results of three applied techniques and water table data from twenty-four observation wells in the basin over the 2000-2010 period are presented. Nine sub- basins were identified and ranked for the RME calculation, where the observation wells-based ranking was taken as standard order for comparison. A linear model has been developed using six factors （drainage density, surface slope, ruggedness index, lineament density, Bouguer gravity anomaly, and potential maximum water retention capacity） and a grid-wise weighted index. In a separate comparative approach, the sub-basin and grid-wise analyses have been conducted to identify the suitable spatial unit for watershed level hydrological modeling.

Amorphous and nanophase microstructures of bulk Se-based chalcogenide alloys

引用

Optoelectronics Letters 2012年第3期8卷 165-167页

作者： abhay Kumar Singh Department of Physics Indian Institute of Science

The composition-dependent microstructural morphology variations of Se89Zn2Te5In4 and Se87Zn2Te5In6 chalcogenide alloys are investigated. Glassy and nanophase surfaces and structural morphologies of these alloys have been described with help of scanning electron microscope (SEM) and transmission electron microscope (TEM), and their elemental concentrations are confirmed from the energy dispersive X-ray spectroscopy (EDX). Experimental results demonstrate that the microstructure of Se89Zn2Te5In4 alloy belongs to pure glassy state, while the Se87Zn2Te5In6 alloy is with nanophase structure.
