Abstract. Satellite gravimetry is used to study the global hydrological cycle. It is a key component in the investigation of groundwater depletion on the Indian subcontinent. Terrestrial mass loss caused by river sediment transport is assumed to be below the detection limit in current gravimetric satellites of the Gravity Recovery and Climate Experiment Follow-On mission. Thus, it is not considered in the calculation of terrestrial water storage (TWS) from such satellite data.

Quantifying process patterns can improve our predictive understanding of how different zones within delta systems will respond to future change.

Abstract:
The present study documents the first occurrence of the high-fin glassy perchlet, Parambassis lala (Hamilton, 1822), in the Upper Krishna River Basin, located in Maharashtra, India. This species is a small, translucent freshwater fish belonging to the family Ambassidae, previously known from the Gangetic plains, Brahmaputra drainage, and other eastern regions of the Indian subcontinent. Its occurrence in the northern Western Ghats represents a considerable westward extension of its known geoical distribution and suggests a potential shift in the ecological boundaries of the species.

Abstract:
Bangladesh is frequently flooded because of its position, which has an impact on livelihoods and housing structures. The Brahmaputra River runs through the Jamalpur District, making it extremely susceptible to periodic flooding. Heavy monsoon rains, coupled with riverbank erosion, further exacerbate the problem, leading to displacement and significant property damage. The rising threat of climate change is expected to intensify these challenges, necessitating innovative flood-resilient housing solutions. The purpose of this study is to create a sustainable and flood-resistant home concept that

Land of rivers, India annually faces the perennial problems of flood and siltation basically along the flood plain region since millennia. Situated on a tectonically active zone and transversed by the Brahmaputra and Barak river system, Assam has been recognized as the worst sufferer. Increasing magnitude and devastation of the hazard is much owed due to the great earthquake of 1950 along with both natural and human-induced factors and activities. The regions located at upper Brahmaputra valley are frequently inundated and eroded wiping away vast areas of cropland, properties, and human lives.

Hence, it is vital to understand the groundwater quality for the proper planning and management of groundwater resources to ascertain its use for drinking and irrigation purposes. This study was conducted in the districts of Biswanath Chariali and Sonitpur, Assam, India, to evaluate the groundwater quality and its suitability for irrigation and drinking purpose. Fifty-six wate

Therefore, there is a difference between the food security of the people living in the desert and the food security of the people living in the coastal areas. If you look at it from that side it is a combination of innumerable hills and plain areas. The diversity of its geographical and natural environment is remarkable. There are many rivers and sub-river

The Brahmaputra basin and the Ganga basin of North Bengal consist of many rivers and most of them originate from the hilly regions of Sikkim, Bhutan, Tibet, and Darjeeling. The Himalayan mountainous region in the state of West Bengal has an annual rainfall of 3000 to 6000 mm. These heavy rainfalls lead to landslides in hilly areas and severe floods in plains, mainly in North Bengal. Sewage discharged from municipalities in these basin areas enters the river water making it unusable even for outdoor bathing. For this reason, Paharpur to Siliguri is the polluted stretch of Teesta in 2018 and alo

Abstract Coastal Bangladesh has experienced large scale changes in erosion and deposition in the Meghna Estuary and the big islands due to the Ganges–Brahmaputra-Meghna stream background. Also, the coastal area is prone to natural disasters almost in every year which creates a change in the ground water level, increases the surface water infiltration, soil salinity, and flood level. Considering these facts of the coastal area of Bangladesh, watershed delineation can contribute to proper planning and management of watershed to mitigate the surface and groundwater problems.

The results indicated that evaporated waters from the Central and South Indian Ocean are the major contributors to the South Asian summer monsoon rainfall, followed by the contribution from the local recycling (precipitated water that evapotranspirated from the South Asian landmass), the Arabian Sea, remote sources and the Bay of Bengal. It was also found that although the direct contribution originating from the Bay of
