Verified

Mohammad Shamsudduha, Richard G. Taylor, Laurent Longuevergne

Journal: Water Resources Research
Year: 2012
Citations: 242

Satellite monitoring of changes in terrestrial water storage provides invaluable information regarding the basin‐scale dynamics of hydrological systems where ground‐based records are limited. In the Bengal Basin of Bangladesh, we test the ability of satellite measurements under the Gravity Recovery ...

Effects of ion temperature on electrostatic solitary structures in nonthermal plasmas

Verified

A. A. Mamun

Journal: Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topicsYear: 1997Citations: 167

Effects of ion temperature on compressive and rarefactive ion-acoustic solitary waves, which have been found to coexist in non-thermal plasmas, are investigated by the pseudopotential approach, which is valid for arbitrary amplitude solitary waves. It is shown that the effects of ion temperature cha...

Satellite-derived surface and sub-surface water storage in the Ganges–Brahmaputra River Basin

Verified

Fabrice Papa, Frédéric Frappart, Yoann Malbéteau, Mohammad Shamsudduha et al.

Journal: Journal of Hydrology Regional StudiesYear: 2015Citations: 95

The Ganges–Brahmaputra (GB), a major river basin of the Indian Sub-Continent (ISC), is the host of more than 700 millions people. In addition to monsoons and strong climate variability, GB is facing growing demands for freshwater availability by a continually growing population and rapidly developin...

Understanding Terrestrial Water Storage Declining Trends in the Yellow River Basin

Verified

Wenlong Jing, Ling Yao, Xiaodan Zhao, Pengyan Zhang et al.

Journal: Journal of Geophysical Research AtmospheresYear: 2019Citations: 72

Abstract Under dual impacts from climate change and human activities, the Yellow River Basin (YRB) of China suffers from droughts and water scarcity. Understanding variations of terrestrial water storage (TWS) over the YRB is significant and beneficial to regional water resources management and sust...

Some new Wyman–Leibovitz–Adler type static relativistic charged anisotropic fluid spheres compatible to self-bound stellar modeling

Verified

Mohammad Hassan Murad, Saba Fatema

Journal: The European Physical Journal CYear: 2015Citations: 60

In this work some families of relativistic anisotropic charged fluid spheres have been obtained by solving the Einstein–Maxwell field equations with a preferred form of one of the metric potentials, and suitable forms of electric charge distribution and pressure anisotropy functions. The resulting e...

Influence of magnetic field on MHD mixed convection in lid-driven cavity with heated wavy bottom surface

Verified

Mst. Umme Mahmuda Maya, Md. Nur Alam, Ahmed Refaie Ali

Journal: Scientific ReportsYear: 2023Citations: 57

This study investigates the influence of a rectangular heat source on magnetohydrodynamic hybrid convection flow in a lid-driven cavity. The effects of various parameters, such as the heat source size, magnetic field strength, and heat absorption/generation, are analyzed. The results show that incre...

Nonlinear propagation of ion-acoustic waves in a hot magnetized plasma with vortexlike electron distribution

Verified

A. A. Mamun

Journal: Physics of PlasmasYear: 1998Citations: 54

Effects of external magnetic field, ion temperature, and vortexlike electron distribution are incorporated in the study of nonlinear ion-acoustic waves in a hot magnetized plasma that consists of a positively charged, hot ion fluid and trapped, as well as, free electrons. It is found that, owing to ...

Nils‐Axel Mörner

Journal: Energy & EnvironmentYear: 2010Citations: 51

Morphological and stratigraphical observational facts in the Sundarban delta provide data for a novel sea level reconstruction of the area. This sea level documentation lacks traces of a global sea level rise. This implies totally new perspectives for the future of Bangladesh. No longer are there an...
