A research site where the thickness of the aquitard reaches 100 m, was instrumented with piezometers, benchmarks and extensometers and monitored for 10 years. Data are analyzed to understand the main drivers and quantify their contribution to the process of land subsidence in Mexico City. Total settlement amounted to 3.661 m, at an average rate of 0.314 m/year. Increase in total stress due to new infrastructure built near the site (a highway) at the start of the monitoring period amounts for 35% of the observed total settlement; this deformation takes place from 0 to 36 m within the aquitard, where pore pressure maintained a hydrostatic distribution. Our analysis shows that the main driver for land subsidence is groundwater pumping from the regional aquifer as most of the deformation due to consolidation (2.128 m) was registered below a depth of 82 m. Since the thickness of the aquitard at the research site is 100 m, numerical simulation shows that most of this deformation most probably takes place at interbedded compressible lenses within the regional aquifer.

Adequate knowledge and understanding of this resource are lacking in this region where water demand has already been increased manifold owing to growing urbanization and climate change. In the present study, prospects of springs have been investigated under different physiographic conditions in the HKH region of Upper Indus Basin, Pakistan for sustainable water resource management. Among 3864 springs identified in the region, a maximum of about 14.9 % springs lie within 1500–2000 m elevation range followed by 14.8 % within 1000–1500 m and 14 % within 3500–4000 m range. A maximum of 1612 springs were observed over high mountains (&gt;3000 m), followed by 927 springs over low mountains (1200–2000 m) and 842 over middle mountains (2000–3000 m). The spring density was observed maximum in the Himalaya (i.e., 0.05 springs/km²) followed by the Hindu Kush range (i.e., 0.04 springs/km²) and the Karakoram range (i.e., 0.01 springs/km²). Overall the density was found to be over 0.03 springs/km² in the three HKH ranges. The spring indicated a positive relationship with annual rainfall (R² value 0.79) highlighting the influence of rainfall in sustaining spring resource in the area. The adoption of an integrated water resource management approach and efficient water use are essential to sustain spring resource in this mountainous region. In-depth research on the hydrodynamic characteristics of springs is essential in the context of changing climate and land use to meet growing water demands and improve communities’ livelihoods in the HKH region in future.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"29 ","pages":"Article 101437"},"PeriodicalIF":4.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly crucial when different mass transfer processes happen at different rates and temporal scales. In an attempt to depict the limiting conditions of multispecies mass transfer within the temporal scales, the present study simulates the fractional mass transfer phenomena in porous media by considering different levels of time fractionation by solving a set of partial differential equations using finite difference method. The incorporation of the time fractionation provides new insights to the solute transport behavior in complex systems, highlighting the changes in the temporal concentration profiles and tailing phenomena. Further, the sensitivity of the flow and transport parameters such as flow velocity, dispersion coefficient, retardation coefficient and contaminant reaction rates are found to be enhanced within the flow domain.

The Minab River Basin, situated in southern Iran, is acknowledged as one of the most extensive basins in the area. Water resources in the area have been reduced significantly as a result of decreases in the flow of the river. Besides drought, human activities were a key factor in decreasing the river discharge. The main object of this research is to assess the effects of various drought-related factors alongside human activities on the water resources surface in from 1995 to 2021. It used statistical analysis to investigate changes in aquifer water and surface flow. Also, meteorological and hydrological drought data were measured by the Standard Precipitation Index (SPI) and Stream Drought Index (SDI). The results show that surface flow decreased by 73% with 32% attributed to climate conditions and the remaining 68 % resulting from human activities. The results obtained also suggest that water levels in the Rudan, Mosafarabad, and Jaghin Tu Kahur aquifers had decreased by 9.47, 8.30, and 16.63 m, respectively, which means the river can no longer receive water from the aquifers. The existence of unauthorized farm dams numbering about 84, the diversion of rivers for floodplain agriculture, and the presence of pits resulting from sand extraction, especially in the Rudan sub-basin are some factors leading to the reduction in water flow into the dam. The presence of dams within river branches during flood events results in a decrease in the volume of water flowing through the rivers.

This review comprehensively evaluates current measurements and trends in GW depletion, along with its causative factors such as excessive pumping, water footprint, and climate change, and their various implications. We reviewed 160 journal articles, along with supplementary data and reports from GW, agriculture, and meteorological authorities. Our focus was on GW depletion in India, with particular emphasis on GRACE satellite data, <em>in situ</em> observations, and the influence of hydrogeological conditions, anthropogenic activities, and climatic disturbances. GRACE observations reveal significant depletion, particularly in Eastern Uttar Pradesh at 7 cm/yr rate from 2002 to 2022, while localized <em>in situ</em> data highlight Punjab as the most rapidly depleting area, with a rate of 46 cm/yr (2003–2012). The intensification of tube well irrigation, the adoption of water-intensive agricultural practices, and poor water management have exacerbated GW depletion. Additionally, Rajasthan and Punjab exhibit high extreme rainfall trends in July and September, indicating unstable monsoon periods in the region. Despite heavy rainfall causing high runoff, Rajasthan shows notable recharge, likely due to its sandstone aquifers' high permeability. In contrast, Punjab is one of the most critically depleted GW hotspots in the country, driven by high depletion trends, deep tube well intensification, increased extreme events, and reduced rainfall recharge.
