The mitigation of human and property losses brought on by TCs depends heavily on the realistic forecasting of TC intensities at longer lead times. In this regard, Accumulated Cyclone Energy (ACE) is the most appropriate measure to access cyclone energy. The study examines the association between ACE and other driving parameters influencing its variability and identifies the robust precursor regions using modern-day machine learning techniques. Initially, the correlation between ACE and driving variables (vertical wind shear, sea surface temperature, specific humidity, tropical cyclone heat potential, relative vorticity, and total column water vapor availability) is assessed. The analysis demonstrates a significant robust association between ACE and associated driving factors over the main cyclogenesis regions. Subsequently, an innovative K-means clustering process and the Causal Effect Network (CEN) based technique employing the PCMCI algorithm are utilized to investigate the relationship among the clustered regions of variables and ACE. Finally, the main contributing regions (MCR) accountable for affecting the changes in the ACE values in the basin are identified. The causal and cluster graphs illustrate the MCRs that exert direct or indirect substantial influence on ACE value. These fluctuations results are caused by the variations of atmospheric and oceanic parameters. These methods may be useful for policymakers and researchers in precise prediction, tracking cyclones, and identifying areas that affect future cyclogenesis.</div></div>","PeriodicalId":101084,"journal":{"name":"Results in Earth Sciences","volume":"3 ","pages":"Article 100078"},"PeriodicalIF":0.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presently, heatwaves are intensifying in terms of frequency, duration, and severity, causing adverse effects such as increased illnesses, human mortality, and forest fires, both in India and globally. This study investigates six climatic zones in India—Arid, Semi-arid, Montane, Humid subtropical, Tropical wet, and Tropical wet &amp; dry—over 31 years (1990–2020), focusing on the summer season. Daily maximum temperature, relative humidity, wind speed, and solar radiation were used to analyze heatwaves, while the Universal Thermal Climate Index (UTCI) and Humidity Index (HD) measured heat stress and discomfort. Our study shows heatwaves are most prevalent in Semi-arid, Montane, and Humid subtropical zones. These zones exhibited a respective increase of (10.94 %, 21.35 %, and 7.03 %), (11.62 %, 22.03 %, and 7.70 %), and (11.76 %, 22.16 %, and 7.84 %) of heatwave events compared to the Arid, Tropical wet, as well as Tropical wet and dry zones respectively. In April 2010, India experienced widespread heatwaves, except tropical wet zone. The Tropical wet zone experienced minimal heat waves, with individuals facing moderate discomfort and heat stress. Thermal stress impacts were greater in the eastern coastal regions of the Tropical wet and dry climates, with notable instances of great discomfort, strong and very strong stress, and dangerous conditions, potentially leading to heat stroke. However, similar stress levels were also observed in the Arid, Semi-arid, and Humid subtropical zones, particularly in May, June, and July.</div></div>","PeriodicalId":101084,"journal":{"name":"Results in Earth Sciences","volume":"3 ","pages":"Article 100076"},"PeriodicalIF":0.0,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143479162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Development through huge accretion and erosion in the Harirampur Char, repeated movement of Amirabad Char from the left bank to the right bank, and straight geomorphological connectivity between Paler Char and Chhitar Char were the main occurrences in the Char lands of the Padma. The morphological changes in Char lands are seen to enforce changes in the banklines around them and, in some cases, in the other co-existing Char lands. The expansion rate of Harirampur Char and the erosion rate in the banks around the Char were mutually related in a half-decadal delay mode. Due to this enforcement, the cyclic evolutions of Char lands contributed to the repeating channel pattern of the Padma. The dynamics of the Ganges-Jamuna confluence enhanced the morphological changes of the Padma, particularly in the upstream segment. High-magnitude floods contributed to making the morphological pattern of the Padma unstable.</div></div>","PeriodicalId":101084,"journal":{"name":"Results in Earth Sciences","volume":"3 ","pages":"Article 100075"},"PeriodicalIF":0.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on surface, groundwater, and thermal springs water in the Larji-Rampur Window (LRW), Himachal Himalaya, with results revealing that the water was alkaline with an average pH of 7.91. The TDS ranged from 16.38 to 367.92 mg/L, while electrical conductivity (EC) varied between 26 and 584 µS/cm. Calcium (Ca^2 +) dominated the major cations (208–2424 µE), followed by magnesium (Mg²⁺), sodium (Na⁺), and potassium (K⁺), with bicarbonate (HCO₃⁻) being the main anion (200–3000 µE). Mixing diagrams, Gibbs plot, and ionic ratios indicated carbonate weathering as the primary factor, with contributions from silicate weathering. The first factor of principal component analysis (PCA) explains 66.44 % of the variance, indicating carbonates as the primary source of dissolved loads in the basin, with contribution from silicate weathering. The isotopic analysis (δ¹⁸O and δD) showed the samples’ alignment along the Global Meteoric Water Line (GMWL), with a slight compositional shift due to water-rock interactions. The δ¹³C values (-13.7 to −3.6 ‰), suggested their derivation from associated carbonate rocks.

This study aims to provide a comprehensive geotechnical and geological assessment of the site, focusing on soil and rock properties, seismicity, and hydrogeological conditions. The primary objective is to develop a geotechnical zoning map that incorporates parameters such as unconfined compressive strength (UCS), porosity, permeability, and resistance to inform safe and efficient mining practices. To achieve this, 15 boreholes were drilled to a depth of 15 m, and various geotechnical tests—including UCS, direct shear, and permeability tests—were conducted. The results revealed significant variability in soil and rock properties—with UCS values ranging from 1.25 MPa to 17 MPa—indicating areas that may require reinforcement. The study also identified low-permeability mudstones and marls—which can lead to increased pore water pressure and potential slope instability—particularly during heavy rainfall events. Seismic analysis indicated that the site is located in a region with a peak ground acceleration (PGA) of 0.30 g for a 475-year return period, which necessitates the incorporation of seismic design principles in construction. The findings underscore the importance of tailored foundation designs, with allowable bearing capacities estimated at 200 kPa for competent strata, along with recommendations for deep foundations in weaker areas.

Analysis of Landsat satellite imagery, combined with social surveys, reveals that despite ongoing land erosion, significant land accretion has occurred during this period. A notable event in 1999 saw the highest erosion rate, resulting in a 25.14 km² land loss. Over the study period, the island's area expanded approximately 42-fold, from an initial 2.44 km² in 1989 to its current size. The accretion of land positively impacted livelihood by increasing the farmland. On the other hand, frequent riverbank erosion displaced the people, damaged their property, and reduced their long-term economic stability and social security. The findings reveal that the livelihoods of people living in the Charland are primarily dependent on agriculture and fishing. However, challenges such as erosion and cyclones disrupt their way of life, pushing many into secondary or alternative jobs. These hardships also contribute to increased school dropouts, early marriages among girls, and a rise in crime and violence, which are closely linked to economic constraints and the lack of sufficient job opportunities.

The lamprophyres are porphyritic and holocrystalline and are composed of pyroxene and amphibole, some of the mafic minerals have been altered to talc. The granitoids are coarse-grained and composed predominantly of plagioclase, with minor quartz, microcline, biotite, and sulfides.

A cement slurry was developed for two liner intervals in the first exploratory well in the Minoo field, SW Iran, at a depth of over 6000 m. The thermal gradient was 1.62 °F/100 ft, significantly impacting cement performance; elevated temperatures can accelerate hydration reactions, potentially causing strength retrogression.
