This study examined trends in eight precipitation and ten temperature extremes in Odisha, India, using RClimDex in R studio with data from the India Meteorological Department, Pune, covering 1980 to 2010 for Khordha, Keonjhar, and Sambalpur. Statistical significance was tested through linear regression and Mann-Kendall tests. Results show a significant shift in climate, particularly in Sambalpur and Khordha, where nine and seven out of ten temperature indices, respectively, exhibited significant changes. The mean maximum temperature increased significantly in Khordha (0.03 °C/year) and Sambalpur (0.026 °C/year), while the mean minimum temperature rose significantly in Khordha (0.03 °C/year) but decreased in Keonjhar (-0.029 °C/year) and Sambalpur (-0.061 °C/year). Cool nights significantly decreased in Khordha (-0.229 days/year) and increased in Sambalpur (0.557 days/year). Warm nights rose significantly in Khordha (0.484 days/year) but declined in Sambalpur (-0.421 days/year). The warm spell duration indicator showed significant increases across all regions, with increments of 0.308, 0.438, and 0.689 days/year in Khordha, Keonjhar, and Sambalpur, respectively. Warm days also rose significantly in Khordha (0.301 days/year) and Sambalpur (0.379 days/year). Regarding precipitation, Khordha showed positive trends in all eight indices, with a significant change in heavy rainfall days. In Keonjhar, no significant changes were observed, while Sambalpur experienced a significant decrease in total annual rainfall (-9.621 mm/year). These findings highlight a significant shift in climate patterns within Odisha, with Sambalpur and Khordha more vulnerable to extreme events compared to Keonjhar.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 1","pages":""},"PeriodicalIF":1.827,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142811179","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 comparison between fixed base and flexible base models is conducted to analyze key design parameters including lateral displacements, inter-story drifts, foundation rotation, natural frequencies, and response spectra. The study focuses on a specific soil profile (Soil profile-1) in Dhaka, comprising cohesive and non-cohesive soil layers. A 42-story structure with four basements, situated on Dhaka soil, is modeled using finite element analysis with Midas GTS NX software. Results reveal that the settlement of the mat foundation exceeds permissible limits for tall buildings supported by a cohesive layer of Dhaka soil, advocating for the practicality and cost-effectiveness of a mat on piling foundation in such scenarios. Dynamic soil-structure interaction analysis demonstrates that although the flexible base model exhibits larger lateral displacement and inter-story drift compared to the fixed base model, these values remain within acceptable limits. Nominal foundation rotation is observed in the mat on pile foundation for Dhaka soil. The study concludes that employing a pile-mat foundation while neglecting soft soil does not significantly alter the analysis for tall buildings with multiple basements in Dhaka, validating the importance of considering SSPSI effects in structural design and analysis.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 1","pages":""},"PeriodicalIF":1.827,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798524","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}

The Hooke and Jeeves algorithm is a local optimization method that can reach a local or global optimum solution depending on the starting model. To prevent convergence to a local optimum, in the present study, the solution is constrained by well-log data. To optimize parameters, the algorithms are first assessed on synthetic data followed by the coal coking and wedge model. The algorithm’s performance is very satisfactory, according to the error analysis between the inverted and anticipated outcomes. Further, a real data application from the Blackfoot field, Canada, has been performed in two steps: First, a composite seismic trace close to the well location is retrieved, inverted into an impedance, and compared with the well-log impedance. The analysis shows how well the well-log impedance corresponds to the inverted impedance. Finally, in the second step, the entire seismic reflection data is subjected to the Hooke and Jeeves–based inversion, and the volume of acoustic impedance and porosity in the inter-well region is predicted. The paper demonstrates that when local optimization is utilized and is constrained by well-log data, the algorithms yield higher-resolution subsurface information. A low impedance anomaly (ranging from 7000 to 9500 m/s g/cc) was detected between 1040 and 1060 ms of two-way travel time, according to the study of inverted impedance. Additionally, the same zone contains an estimated high porosity anomaly (&gt; 12%) that is thought to be a sand channel/reservoir.

The technique used for resource estimation not only estimates dynamic resources, as it has in the past, but also estimates static groundwater resources in weathered aquifers. It has been found that static resources are more than three times more abundant than dynamic resources that go unutilized.

These depressions contain considerable drainable static groundwater resources that can be exploited for sustained extraction by implementing area-specific Aquifer Storage and Retrieval or Artificial Recharge and Retrieval system.

The spatial impact of the seismic wave component propagation with elevation was discovered by the examination of the time-history of accelerating. The suggested law of variation damping ratios for the propagation of seismic wave components used processing half-power bandwidth as well as the Fast Fourier Transform (<i>FFT</i>). Its main frequency for propagation of seismic waves was quantified using the spectral ratio of the horizontal component spectrum (<i>H</i>_c) to the vertical component spectrum (<i>V</i>_c), and the predominant frequency of propagation was obtained quantitatively. Furthermore, piecewise spectral curves were refined, and the frequency and specific period spectral differences of the speed increase components at different vibration stages were characterized. The findings demonstrated that when relative height rose, the peak acceleration ratio of the horizontal and vertical components also increased. When the weak structural plane is present, the horizontal acceleration component can propagate directly through the weak structural surface. Vertical acceleration occurs at this point of seismic wave reflection and propagation. The weak structural face has a significant blocking effect on the acceleration amplification of the overlying slope. The slide bed and landslide mass’s horizontal component featured a rich low-frequency component. The primary frequency component spanned from 1.5 to 14.1 Hz.

First, the dam body and its foundation were accurately modeled in PLAXIS 3D. The datum was collected from official reports. A specific section of the dam and foundation in which some instruments were placed was selected and a comparison of settlements in different parts was made between instrument data and finite element method (FEM) analysis. Since there was no favorable fitting, back analysis seemed to be crucial. Response surface methodology (RSM) was adopted to make some equations that can replace the hardening soil model and be easy to be optimized for desired settlements. Since the runs in the FEM software, PLAXIS 3D would take considerable time and energy, a new approach to use RSM was introduced which is called two-step RSM. It could be seen that if sensitivity analysis is performed on a linear RSM model at first, the second-order model of soil behavior can accurately be predicted with much less effort. Some statistical tests such as <span>({sigma }^{2})</span> and <span>({R}_{adj}^{2})</span> were considered to prove the adaptability of the new method. Two second-order RSM equations, for both core and shell, were optimized with the help of a genetic algorithm. The results suggested an acceptable fit when compared to instrumental data.
