Nature-based solution enhances resilience to flooding and catalyzes multi-benefits in coastal cities in the Global South
Jérôme Chenal, Paolo Perona, Charlotte Grossiord, Emmanuel Qays Dubois, Montana Marshall
Coastal cities are facing a rise in groundwater levels induced by sea level rise, further triggering saturation excess flooding where groundwater levels reach the topographic surface or reduce the storage capacity of the soil, thus stressing the existing i ...
2024rrechaRge an R package for integrated groundwater recharge modelling
Context • Groundwater major water resource throughout the world that is heterogeneously distributed and sustains diversified uses • The sustainability of groundwater usage highly dependent on the relative rates of groundwater abstraction e g via pumping) a ...
2024Contribution of standardized indexes to understand groundwater level fluctuations in response to meteorological conditions in cold and humid climates
Understanding the fluctuations in groundwater levels in response to meteorological conditions is challenging, especially given the slow transit time associated with groundwater reservoirs and the short duration of time series for groundwater levels. Nevert ...
2024Data-driven statistical optimization of a groundwater monitoring network
Andrea Rinaldo, Gianluca Botter
We propose a comparative study of three different methods aimed at optimizing existing groundwater monitoring networks. Monitoring piezometric heads in subsurface porous formations is crucial at regional scales to properly characterize the relevant subsurf ...
Elsevier2024Watertable fluctuations in coastal unconfined aquifers with a sloping sea boundary: Vertical flow and dynamic effective porosity effects
David Andrew Barry, Zhaoyang Luo
Interactions between the tide and sloping sea boundary make watertable fluctuations in coastal unconfined aquifers complicated. Based on a perturbation method, we derived a new analytical solution to predict watertable fluctuations for coastal unconfined a ...
2023Effects of Unsaturated Flow on Salt Distributions in Tidally Influenced Coastal Unconfined Aquifers
David Andrew Barry, Zhaoyang Luo
Unsaturated flow influences both the seawater extent under steady-state conditions and the propagation of tides in coastal aquifers. However, its effects on salt distributions in tidally influenced coastal aquifers are little investigated. The present stud ...
2023Spatially adaptive machine learning models for predicting water quality in Hong Kong
Rongrong Li, Qiaoli Wang, Yu Xu
Water quality prediction in the spatially heterogeneous environment is challenging as the importance of water quality parameters (WQPs) and the performance of prediction models may vary across space. Thus, this study proposed spatially adaptive machine lea ...
ELSEVIER2023Development of a magnetic calcium-alginate hydrogel-sphere encapsulated with Fe-Mn-Zr ternary metal composite for heavy metal adsorption
Heavy metal contamination has become one of the greatest global environmental problems. In this study, a magnetic calcium-alginate hydrogel-sphere encapsulated with Fe-Mn-Zr ternary-metal composite (MCHETC) was prepared through a combined co-precipitation ...
2023Advances in polymer-based nanocomposite membranes for water remediation: Preparation methods, critical issues and mechanisms
Membrane technology is a growing tool for contaminants removal from polluted water. Although various types of polymeric membranes have been developed for water remediation, the common drawbacks like fouling, hydrophobicity and low mechanical strength are y ...
London2023Structure of a membrane-bound menaquinol:organohalide oxidoreductase
Christof Holliger, Henning Paul-Julius Stahlberg, Julien Maillard, Dongchun Ni, Lorenzo Cimmino
Organohalide-respiring bacteria are key organisms for the bioremediation of soils and aquifers contaminated with halogenated organic compounds. The major players in this process are respiratory reductive dehalogenases, corrinoid enzymes that use organohali ...
