Constraining the response of continental-scale groundwater flow to climate change

Scientific Reports, 2022
Numerical models of groundwater flow play a critical role for water management scenarios under climate extremes. Large-scale models play a key role in determining long range flow pathways from continental interiors to the oceans, yet struggle to simulate

Analysis of groundwater runoff patterns in Zhangguan-Paihuadong karst water system in the south of the Mingyue gorge anticline

Carsologica Sinica, 2022
The long-term interaction between groundwater and karst development in eastern Sichuan has created a unique groundwater runoff pattern and caused a complex hydrogeological problem of karst engineering. Hence, finding out the groundwater runoff pattern in

Response of redox zonation to recharge in a riverbank filtration system: a case study of the Second Songhua river, NE China

Hydrology Research, 2020
Bank filtration induced by groundwater pumping results in redox zonation along the groundwater flow path. Besides the river water, recharge from other sources can change local redox conditions; therefore, redox zonation is likely to be complex within the

Optimal Management of Flow in Groundwater Systems

Eos, Transactions American Geophysical Union, 2000
Groundwater simulation models are physically based mathematical models derived from Darcy's law and the law of conservation of mass. Various established solution techniques utilizing either the finite difference or the finite element method, or a combination of both, are available for solving the governing equation of the model, provided that model ...
