In the present study, an effort was made in Kashmir Valley, NW-Himalayas to delineate potential groundwater areas using GIS and Analytical Hierarchy method (AHP) by incorporating remote sensing data with from other sources. These sets were used prepare eight thematic layers of slope, soil texture, drainage density, land/land cover (LULC), lithology, geomorphology, lineament rainfall. The analytical AHP pair wise matrix evaluate normalized weight these layers. All their corresponding classes...
Abstract Snow and glacier melt are significant contributors to streamflow in Himalayan catchments, their increasing contributions serve as key indicators of climate change. Consequently, the quantification these components holds importance for effective water resource management. In this study, we utilized spatio‐temporal variability isotopic signatures stream water, rainfall, winter fresh snow, snowpack, glaciers, springs, wells, conjunction with hydrometeorological observations Cover Area...
Intermontane basin aquifers worldwide, particularly in the Himalayan region, are recharged largely by adjoining mountains. Recharge these basins can occur either water infiltrating from streams near mountain fronts (MFs) as front recharge (MFR) or sub-surface block infiltration (MBR). MFR and MBR challenging to distinguish least quantified, considering lack of extensive understanding hydrological processes This study used oxygen hydrogen isotopes (δ18 O δ2 H), electrical conductivity (EC)...
Abstract The spatial distribution of water isotopes provides essential scientific data for understanding many hydrological, paleoclimate, and ecological processes. limited isotopic across the Himalayan River Basins (HRB) obstructs study basin‐scale hydrological New stable oxygen hydrogen from Indus, in combination with a comprehensive compiled set HRB, was used first time to create isoscapes (δ 18 O d‐excess) specifically representing surface water. δ d‐excess isoscape define clear...
<p>We have used stable isotopes of oxygen and hydrogen (δ<sup>18</sup>O δD) which are important tracers for understanding various hydrological processes, to assess the spatial temporal variability due dual moisture sources in Upper Jhelum River Basin (UJRB) north-western Himalayan region. The HYSPLIT back trajectory analysis shows large transport pathways over region during Southwest monsoon (SWM) is mainly restricted...
<p>The present study explores the signature of stable isotopes (δ<sup>18</sup>O and δD) major inorganic solute ion concentrations Satluj river water its tributaries to gain insight into dominant hydrogeochemical process that controls chemistry in River Basin (SRB), Himalayas, India. In isotopic geochemical terms, surface SRB is poorly characterized for whole length; their potential variability has yet be widely used as an...
<p>Isotopic landscapes or “Isoscapes” are a valuable tool for studying hydro-climatic processes and their impact on water supplies at various spatial scales. These isoscapes extremely useful because they enable the documentation visualization of large-scale hydrological occurring regional, continental, global scale. This study focuses surface isotope data (present published data) to interpolate, develop Himalayan basins (Indus, Ganga, Brahmaputra),...
