Numerical modelling study on non-steady-state groundwater flow systems in response to changing rainfall

open access: yes地质科技通报, 2023
Objective Geological, climatic, and topographical conditions control regional groundwater flow systems. Previous researchers have made significant advancements in developing the theory of groundwater flow systems under steady-state climatic conditions ...

Suitability of Natura 2000 sites for threatened freshwater species under projected climate change

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1872-1887, December 2022., 2022
Abstract As part of the world's largest coordinated network of protected areas, Natura 2000, European Union member states designate special areas of conservation (SACs) to maintain or achieve favourable conservation status for imperilled aquatic species listed under Annex II of the Habitats Directive.

Effects of coal mining and tunnel excavation on groundwater flow system in karst areas by modeling: A case study in Zhongliang Mountain, Chongqing, Southwest China

open access: yesJournal of Groundwater Science and Engineering, 2023
A karst groundwater system ranks among the most sensitive and vulnerable types of groundwater systems. Coal mining and tunnel excavation can greatly change the natural hydrogeological flow system, groundwater-dependent vegetation, soil, as well as ...

Flow and Storage in Groundwater Systems [PDF]

open access: yesScience, 2002
The dynamic nature of groundwater is not readily apparent, except where discharge is focused at springs or where recharge enters sinkholes. Yet groundwater flow and storage are continually changing in response to human and climatic stresses. Wise development of groundwater resources requires a more complete understanding of these changes in flow and ...

Young children's perspectives of time: New directions for co‐constructing understandings of quality in ECEC

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

A multi-criteria approach of assessing groundwater potential, recharge and flow in the transboundary Tuli Karoo Basin

open access: yesWater Practice and Technology, 2022
Quantitative estimates of amount of groundwater resources are required in the transboundary Tuli Karoo Basin to better manage and promote sustainable conjunctive use of the aquifer. Unfortunately, such important data and information are lacking.

Lumped cluster analysis for understanding spatial and temporal patterns of groundwater geochemistry and hierarchically nested flow systems

open access: yes地质科技通报, 2022
Hydrogeochemical tracing is an important tool to identify groundwater flow systems.However, the complexity of regional hierarchically nested groundwater flow systems makes it more difficult to explain chemical compositions of groundwater.This study takes

Functional Flows in Groundwater-Influenced Streams: Application of the California Environmental Flows Framework to Determine Ecological Flow Needs

open access: yesFrontiers in Environmental Science, 2022
Environmental flows, or the practice of allocating water in river systems for ecological purposes, is a leading strategy for conserving aquatic species and improving river health.

Reflections on Bayesian inference and Markov chain Monte Carlo

open access: yesCanadian Journal of Statistics, Volume 50, Issue 4, Page 1213-1227, December 2022., 2022
Abstract Bayesian inference and Markov chain Monte Carlo methods are vigorous areas of statistical research. Here we reflect on some recent developments and future directions in these fields. Résumé L'inférence bayésienne et les méthodes de Monte‐Carlo par chaîne de Markov sont des domaines dynamiques de la recherche statistique.
