Abstract :

River erosion in the Brahmaputra basin is a common phenomenon, but it also causes adverse effects on human beings and the environment. This study illustrates the dynamics of channel shifting and bank erosion for the last five decades of the mighty Brahmaputra River. It was found that the Brahmaputra River was expanding/widening over time and is about 45% from its previous width in 1972. During 1972-2020, a total of 199.00 sq. km of land (agriculture/vegetation) area was eroded by the…

CFD Analysis of Blood Flow through Bifurcated Carotid Artery (of Human): Newtonian vs. Non Newtonian Blood Model

Corresponding Author : Md. Syamul Bashar (md.syamul-mee@sust.edu)

Abstract :

Blood behaves like either a Newtonian or Non-Newtonian fluid depending on the shear stress it experiences. In the current study, a 3D model of a human bifurcated carotid artery was used to get insights into the differences between Newtonian and Non-Newtonian blood flow. As the experimental or numerical setup will be made simpler by representing blood as a Newtonian fluid. We are interested in whether it makes sense to represent blood as a Newtonian fluid. Fluent (ANSYS, 15) software was…

Analyzing Groundwater Potential Recharge Zones Using AHP, RS and GIS Techniques in Bishwamvarpur Upazila, Bangladesh

Corresponding Author : Towfiqul Islam Khan (khan-gee@sust.edu)

Abstract : This study shows the demarcation of capacity zones where groundwater can get recharged in Bishwambharpur Upazila in Sunamganj, Bangladesh by using analytic hierarchy process, remote sensing, and geographic information system techniques. To create thematic maps of several geospatial factors having an immediate or indirect effect on the availability of groundwater, geology, slope, geomorphology, soil, LULC (land-use land-cover), drainage density, lineaments density, and rainfall distribution, remotely sensed and conventional statistics have been obtained from several reasserts and analyzed in GIS software.…
