Contribution of standardized indexes to understand groundwater level fluctuations in response to meteorological conditions in cold and humid climates

Journal of Hydrology, Journal Year: 2024, Volume and Issue: 634, P. 131105 - 131105

Published: March 24, 2024

Understanding the fluctuations in groundwater levels response to meteorological conditions is challenging, especially given slow transit time associated with reservoirs and short duration of series for levels. Nevertheless, this knowledge crucial water resource management, that global warming will drastically impact hydrological dynamics cold humid climates. The objective work was quantify how standardized indexes contribute understanding level climates (10 23 years). relationships between precipitation index (SPI), temperature (STI), climate indexes, (SGI) were analyzed. reactivity examined 2000 2022 using measurements from 152 wells located 46°N 52°N province Quebec (Canada). results showed available sufficient provide new insights into role on fluctuations, demonstrating usefulness indexes. One main contributions study hydrogeological systems go through an annual reset due prolonged freezing period. This one drivers isolating year-to-year conditions, contributing short-duration droughts.

Estimation of Groundwater Recharge and Assessment of Groundwater Quality in the Weining Plain, China

Water, Journal Year: 2025, Volume and Issue: 17(5), P. 704 - 704

Published: Feb. 28, 2025

The Weining Plain is in the semi-arid northwest region of China, with groundwater as its main source for various purposes. This research provided a detailed investigation into exploitation status Plain, analyzed quality different purposes, and estimated recharges using water budget analysis end member mixing analysis. entropy index was applied to assess overall drinking water, industrial several agricultural indicators were used assessment uses. findings showed that recharge area primarily comes from irrigation infiltration leakage canal system which account approximately 50–60% total recharge. poor, over 80% being moderate poor requiring treatment. A large proportion suitable irrigation. However, has corrosive effect on boilers, there high risk boiler scaling foaming. Only 12.41% samples have good use, treatment uses needed. study can help local decision-makers understand availability resources manage reasonably.

Evaluation and Prediction of Water Quality of Typical Wetlands in the Source Region of the Yangtze River

Water, Journal Year: 2023, Volume and Issue: 15(8), P. 1612 - 1612

Published: April 20, 2023

Wetlands play an important role in water storage and conservation, but with global climate change, the degradation of wetland ecosystems is accelerating. In this study, we conducted research on current situation future prediction quality typical wetlands source region Yangtze River to provide a scientific basis for protection restoration River. The Bayesian assessment method Yao Zhiqi evaluation were used evaluate from 2016 2021 based change scenarios three RCPs (Representative Concentration Pathways) under CMIP5 (Coupled Model Intercomparison Project Phase 5) model SWAT (soil tool) hydrological model, 2022 2100 was predicted. results show that inter-annual changes CODMn, NH3-N, TN downward trend, while temperature DO concentration upward trend 2016–2021. temperature, conductivity within year are abundant season > flat dry season; DO, NH3-A, TN, TP concentrations opposite. has reached Class II above. From 2100, future, TP, will continue rise, decline. Therefore, pressure resources further aggravated, so it urgent strengthen protection.

Spatiotemporal Variation and Influencing Factors of Grain Yield in Major Grain-Producing Counties: A Comparative Study of Two Provinces from China

Land, Journal Year: 2023, Volume and Issue: 12(9), P. 1810 - 1810

Published: Sept. 20, 2023

The exploration of the spatiotemporal variations and influencing factors grain yield in major grain-producing regions is greatly important to maintain stable sustainable agriculture. Taking Henan Province Heilongjiang as examples, this study reveals characteristics at county level by using multisource data on economy, society, natural geography from 2000 2021 employing methods such coefficients variation, standard deviational ellipses, spatial autocorrelation analysis. Moreover, geographical detector geographically weighted regression models are combined explore differences significant between these provinces heterogeneity coefficients, respectively. following findings drawn: (1) Grain both gradually increased, with notable annual growth rate, proportion, level. (2) number high-yield counties significantly increased their distribution became more concentrated, indicating a shift main regions. (3) overall correlation steadily local transitioned random gradual aggregation. (4) There were factors, where environment, socio-economic input all affected provinces. In summary, provides scientific reference for governments worldwide formulate rational effective food production policies, thereby contributing global security social development.

Extreme Hydrological Drought in Southern Quebec (Canada): Natural and Anthropogenic Factors Interactions on its Spatio-Temporal Variability

International Journal of Environmental Sciences & Natural Resources, Journal Year: 2023, Volume and Issue: 32(5)

Published: Oct. 4, 2023

Despite the relatively humid character of their climate, many cold temperate regions face increasingly extreme hydrological droughts that turn rivers from steady to intermittent.The spatio-temporal variability these depends on interaction natural and anthropogenic factors.The objective this study is determine factors in southern Quebec (Canada).The annual daily minimum flows (1-day) 17 rivers, grouped into three homogeneous hydroclimatic regions, were analyzed during period 1930-2019.With regard spatial variability, comparison flow averages by means ANOVA Kruskal-Wallis tests revealed north shore (southwestern region) are average twice as higher than those (Southeastern Eastern regions).Linear correlation analysis negatively correlated with agricultural areas snowfall but positively wetlands watershed mean slopes.As for temporal southeastern region river flows, most agricultural, have increased significantly over time due significant decrease increase amount rainfall.In eastern region, generally decreased autumn snowfall.Finally, southwestern less overall, no change occurred, probably low fall snowfall, which was offset rainfall.This reveals vulnerable snow, main source Quebec.Finally, few correlations observed between climatic indices flows.
