The inner shelf floor is carpeted by sand with varying grain sizes from coarse, medium and fine to very fine sand. The heavy mineral content of the surface sediments ranges from 0.19 to 4.05 wt% with an average of 1.10 wt%. Heavy mineral enrichment is noticed in the fine-grained sands exhibiting moderately sorted, near symmetrical to strongly negatively skewed and meso-to leptokurtic nature. Relatively higher abundances of amphiboles, orthopyroxenes, clinopyroxenes, garnet, epidote, kyanite and staurolite occur in the coarser size (> 250 µm) grade, whereas the predominance of opaques, with transparent minerals such as sillimanite, rutile, sphene and tourmaline occurs in the medium size (250 to 125 µm) grade. A relatively higher abundance of monazite and zircon occurs in the finer (125–63 µm) size grade. A major proportion of the light-heavy minerals viz., amphiboles, orthopyroxene, clinopyroxene and sillimanite shows a northward increasing trend between 10 and 20 m water depths, which could be attributed to the northerly drift of lighter heavies from the sediments by longshore current. The heavy mineral assemblage constitutes ilmenite, magnetite, amphiboles, pyroxenes, garnet, sillimanite, epidote, zircon, monazite, kyanite, staurolite, sphene, tourmaline and corundum, suggesting a provenance of mixed igneous and metamorphic rocks of Archean and Proterozoic age, reworked sedimentary rocks of Gondwana, Cretaceous and Cuddalore formation and coastal quaternary sediments of the hinterland. The northerly littoral drift might have brought these heavy minerals and redistributed them in the study area.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 5","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888713","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 paper investigates the root causes of this crisis and proposes viable solutions for effective mitigation. The city has experienced 37.75% less rainfall in 2023 compared to the decadal average annual rainfall. The stage of groundwater extraction has increased from 193% in the year 2022 to 217% in 2023, and the city is categorized as “over-exploited.” The study reveals that the rainfall deficit in 2023, coupled with escalating groundwater extraction rates and adverse land use practices, is exacerbating the depletion of aquifers and drying up of borewells. The demand of water in the city is estimated to be 1891 million liters per day (MLD) out of which the current supply after losses is calculated to be 1273 MLD leading to a deficit of 618 MLD. Furthermore, areas lacking a comprehensive Cauvery water supply exhibit deeper water levels, highlighting disparities in access to groundwater resources. To address these challenges, the paper suggests a multifaceted approach encompassing regulatory measures, technological interventions, and community engagement. Bengaluru’s water crisis stems from rapid urbanization, population growth, and groundwater depletion, requiring immediate and long-term interventions. Removing encroachments on lakes and desilting them can enhance groundwater recharge and mitigate flooding. Utilizing treated sewage water from BWSSB’s STPs for lake recharge and public use can conserve freshwater. Large residential complexes must implement recharge trenches, while bulk water suppliers should be regulated to prevent over-extraction. Enforcing rainwater harvesting laws, penalizing freshwater misuse, and promoting water-saving fixtures can further reduce demand. Additionally, exploring alternative surface water sources like Yettinahole and Mekadatu projects will help ensure Bengaluru’s long-term water sustainability.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 5","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879716","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}

A comprehensive testing initiative was conducted to assess the UCS, sieve analysis, Atterberg limits, and specific gravity of natural soils. To overcome the limitations of existing UCS predictive models in covering output variability for the fine-grained natural soil deposit, a diversity of input parameters defining natural soil attributes, such as the percentage of fines, sand, plasticity index (PI), specific gravity (Gs), and liquid limit (LL), were employed. Multiple ML models were developed through Python code with varying algorithm inputs, and the models with the best predicting abilities were analyzed. The ability of the ML models to predict based on the number of statistical performance indices (SPIs) such as correlation indices, i.e., coefficient of determination (<i>R</i><sup>2</sup>), Nash–Sutcliffe efficiency (NSE), and Pearson correlation coefficient (PCC); and error indices, i.e., root mean square error (RMSE), Willmott index (WI), and mean absolute error (MAE), were analyzed and found to be reasonable based on SPIs. Based on the rank analysis of SPIs, the XGB model was proposed to predict the UCS value of natural soils. Sensitivity and parametric analyses revealed that LL has the most significant effect on prediction in the proposed model, pursued by PI, fines, sand, and Gs.

The Sarayan basin is situated in the interfluve region of the Gomati and Ghaghara River within the Middle Ganga Plain. It is the left tributary of the Gomati River that flows within the Ganga Plain of Uttar Pradesh, India. Various parameters, including linear, areal, relief, geometric, and morpho-tectonic, were calculated to assess the basin’s shape, drainage pattern, and topographical characteristics. It is classified as a fifth-order stream. It exhibits a dendritic type of drainage pattern that covers an area of 1695 km<sup>2</sup>. The analysis reveals the basin characteristics by a mature alluvial river system, dendritic drainage pattern, indicating homogeneity in texture and underlying geology and stable geomorphic conditions. Linear parameters indicate a gentle ground slope and minimal soil erosion within the basin. Areal parameters further emphasize smooth topography, low runoff potential, gentle slope, lower susceptibility to soil erosion, efficient infiltration, and enhanced permeability, resulting in prolonged flow paths that facilitate effective groundwater recharge processes. Morphtectonic parameters, including the sinuosity index (1.60), reveal diverse levels of channel sinuosity within the basin. Values ranging from 1.07 to 1.27 signify low sinuosity, while those between 1.31 and 1.44 suggest heightened sinuosity and lateral erosion.

In this research, the western part of the Kopet-dagh Orogen, as the southern boundary of the Turan Plate, is selected as a case study for investigation on tectonic development and deformation patterns, using surface–subsurface structural studies together with complementary remote sensing and GIS environmental capability as a multi-disciplinary approach. The results of this research determined two sets of faults, consisting of (a) first-stage longitudinal reverse faults with a structural trend of N90–100 to N50–70 (Tangrah, Takal-Kuh, Marave-Tappe, and Golijeh faults), and (b) transversal right-hand strike-slip faults with a trend of N130–150 (Kalaleh, Ughcheh, and Sarighamish faults). These two sets of faults formed the structural framework of this zone and played an important role in the tectonic evolution (initiation, shaping, evolution of sedimentary basins, and forming a fold-thrust belt) of this orogen. A change in the mechanism of the first-stage longitudinal faults, as tectonic inversion, at the onset of the Late Alpine Orogeny caused the re-arrangement of P-axes and thus formed bi-vergent reverse faulting in the northern and southern edges of this zone. Subsequently, fault propagation folds were established due to this event. Finally, an extensive V-shaped compressional pop-up structure with bi-vergent thrusting and fold axial surfaces (as fault-related folds) was formed in the Kopet-dagh fold-thrust belt. Also, the mechanism of the second-stage transversal faults changed to right-hand strike-slip faults with some normal components at the onset of the Late Alpine Orogeny. The normal component of these faults (especially the Kalaleh fault) caused the settlement of the western part of this zone along them and formed the Gorgan-Gonbad plain.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 5","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821779","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}
