Abstract Given that the concentration of 222 Rn in groundwater is much higher than surface water and its radioactive half‐life (3.83 d) short, an effective tracer groundwater–surface interactions. In this study, a new mass balance method presented, which can be used to estimate specific interactions within river reach. Three possible situations interaction between are considered, equations based on conservation formulated for judging processes calculating flux. A case study was conducted...
Abstract This study explores the potential of machine learning algorithms for earthquake prediction, utilizing fluid chemical anomaly data from hot springs. Six springs, located within an active fault zone along southeastern coast China, were carefully chosen as hydrochemical monitoring sites extended period two and a half years. Using this data, prediction model integrating six was developed to forecast M ≥ 5 earthquakes in Taiwan. The model's performance validated against recorded events,...
Abstract. The change of climate and environmental conditions has obviously affected the evolution propagation drought in river basins. Hun River basin (HRB) is a region seriously troubled by China, so it particularly urgent to evaluate hydrological investigate threshold triggering HRB. In this study, standardized runoff index (SRI) was applied reveal characteristics drought. Meanwhile, based on duration severity identified run theory, copula function with highest goodness fit selected...
Abstract The evolution of meteorological drought under global warming is great significance to risk management. Meanwhile, driving factors that influence hydrological and water cycle processes play an important role in assessment. Hun-Taizi River basin (HTRB) a region seriously troubled by China. Therefore, we reveal the characteristics its factors. First, standardized precipitation index (SPI) was adopted characterize drought. copula functions with highest goodness fit were established...
The Dongying geothermal resources are an important part of the deep in Tianjin Binhai New Area, and these will determine whether demand target can be met. There is urgent need to find favorable areas for develop safely, stably efficiently. recoverable potential reservoir different positions calculated by simulating predicting water level, which as index zoning evaluation. By using analytic hierarchy process (AHP), comprehensive indexes exploration development regionalization quantified. A...
Dongying’s Paleogene geothermal resources are an important part of the Tianjin coastal region. The extent fluid and supply relationship have become increasingly important, will determine whether demand targets can be met. formation in regions is widely distributed to east Cangdong fracture, but it absent west fracture. On basis introducing geological characteristics depositional Dongying formation, we analyzed hydraulic conductivity fracture reservoir from aspects condition, dynamic...
Karst groundwater samples were collected in the Xiongxian geothermal field for δ18O and δ2H data analysis. Both oxygen (-8.4‰ to -8.6‰) hydrogen (-72.4‰ -73.0‰) isotopes found enriched than precipitation (-9.4 -11.7‰ -76‰ -85‰ δ2H, respectively) late Pleistocene, when karst was recharged. The isotope is attributed water-dolomite interaction low-middle temperature field. ratio calculated as 0.3, based on exchange. deduced be caused by bacterial SO42− reduction.
Baiyangdian Lake, recognized as the largest freshwater body in northern China, plays a vital role maintaining regional eco-environment. Prior studies have pointed out contamination of sediments with heavy metals, raising concerns about eco-environmental challenges. Therefore, it is imperative to evaluate current pollution levels and ecological threats related metals found Lake well its inflow rivers. In May 2022, surface depth less than 20 cm were analyzed for Cu, Zn, Pb, Cr, Ni, As, Cd, Hg...
Intensive agriculture and industrial activities have resulted in contamination rivers groundwater quality, which threatens human health. In this study, we used comprehensive physiochemical indicators to assess the quality of for drinking irrigation addition potential risks local residents a riverbank filtration site. Human health through water intake dermal contact were also estimated. Moreover, analyzed spatial distribution regularities risk values The assessment results revealed that...
Abstract Geochemical responses of saline aquifers toward large quantities CO 2 injection are important to the monitoring and safety assessment storage. Detailed studies on water‐rock‐CO interactions non‐marine through three batch‐reaction experiments were carried out under simulated reservoir conditions (T = 100°C, P 10 MPa). pH decreased by 1∼2 TDS increased 268 mg/L ∼561 mg/L. Water type evolved from original Cl·SO 4 ‐Na HCO 3 with a water/rock ratio 3:1. Chemical components , Ca, Mg K...
Accurate prediction of non-point source water pollution is conducive to the prevention and control rural pollution.To improve accuracy agricultural achieve timely control, a model based on grey correlation method designed.According historical data nonpoint pollution, influencing factors degree are determined by using method, standardized pretreatment carried out.The results transformed into function expression forms, original sequences different generated, which brought table results,...
Groundwater is the main irrigation water source in Upper Peacock River. As fast enlargement of areas continues recent years, groundwater level declines continuously and has posed a threat to sustainability local agriculture ecology. A numerical model was established with code MODFLOW–2000 order predict declining trend formulate measures counter overexploitation, which river–aquifer interaction elaborated characterized by field survey. The results show that under current intensity withdrawal,...
Geothermal systems represent discrete and relatively homogenous habitats for extremophiles; investigation into the microbial community is key to revealing geochemical environment evolution of fluids in geothermal reservoirs. The reservoir Lindian field Northeast China, highly reducing rich methane, but pathways methane generation related structure are still unclear. In this research, five thermal water samples were collected tested, diversity analyzed. results show that sandstone belonging...
Unreasonable exploitation of groundwater resources in the Kongque River region has led to a decline table, salinization, and other geo-environmental problems.Therefore, this study supplements studies on soil water salt transport region, provides new method for prevention salinization arid semiarid regions.In study, column experiments were carried out investigate influence lithological structures unsaturated zone, quality, methods irrigation transport.Based data from experiment,...
