Groundwater flow in eastern Ottawa

open access: yesCanadian Geotechnical Journal, 1970
A mile-long line of piezometers were installed at various depths in a clay terrace system east of the City of Ottawa. Measurements indicated a significant downward piezometric gradient through the clay layer to the underlying bedrock. The downward flow of water through the clay affects both existing effective stresses and the stress history of the ...

Numerical simulation of saturated-unsaturated groundwater flow and contaminant transport in a karst aquifer

open access: yes地质科技通报, 2022
Groundwater in karst aquifers is an important source of drinking water. Due to the complexity of hydrogeological characteristics, it is extremely challenging to analyze and evaluate the groundwater environment in karst aquifers by numerical modeling.

Characteristics of Groundwater Flow in Tidal Wetland in Pearl River Estuary under Heterogeneous Conditions

open access: yesRedai dili, 2022
Groundwater flow in tidal wetlands is an important part of coastal estuarine hydrological cycle. The results of previous studies were based on the condition that the aquifer was homogeneous. Moreover, the understanding of groundwater circulation in tidal

An Approximate Method of Images for Finite and Non-Linear Boundaries [PDF]

open access: yes, 2014
The method of images is used in many different modeling scenarios such as electrostatics, fluid mechanics, and groundwater flow modeling to create infinitely long linear boundaries, such as a no-flow boundary across which flux is zero.

Hierarchically MOF‐Based Porous Monolith Composites for Atmospheric Water Harvesting

open access: yesAdvanced Materials, EarlyView.
This review explores the design of hierarchical porous materials for atmospheric water harvesting, focusing on metal‐organic frameworks (MOFs) and porous monoliths. Emphasis is placed on integrating MOF nanoscale porosity with the microscale channels of monolithic scaffolds to enhance sorption‐desorption performance.

Cascade Electrocatalytic Reduction of Nitrate to Ammonia Using Bimetallic Covalent Organic Frameworks with Tandem Active Sites

open access: yesAngewandte Chemie, EarlyView.
Fabricating covalent organic frameworks electrocatalyst with bimetallic active sites and promoting cascade electrocatalytic reduction of nitrate to ammonia through the copper‐cobalt tandem mechanism. The Cu sites serve as the activation centers for adsorption and the initial 2e− process. The ‐N‐Co‐O‐ interface promotes water adsorption and dissociation,

Groundwater flow in a fissurised porous stratum

open access: yesNetworks & Heterogeneous Media, 2010
Barenblatt e. a. introduced a fluid model for groundwater flow in fissurised porous media. The system consists of two diffusion equations for the groundwater levels in, respectively, the porous bulk and the system of cracks. The equations are coupled by a fluid exchange term. Numerical evidence suggests that the penetration depth of the fluid increases
