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 ...

Stagnation lines and its control of nested groundwater flow systems in three-dimensional Tóthian basins

open access: yes地质科技通报, 2022
The theory of groundwater flow systems proposed by Tóth, which was based on the two-dimensional profile flow field, has become the theoretical basis for studying basin-scale groundwater circulation.The stagnation points on the two-dimensional profile can

Thermal Impact by Open-Loop Geothermal Heat Pump Systems in Two Different Local Underground Conditions on the Alluvial Fan of the Nagara River, Gifu City, Central Japan

open access: yesEnergies, 2022
An alluvial fan is a good area to install open-loop geothermal heat pump (GHP) systems due to shallower aquifers, faster groundwater flow, and fewer land subsidence risks.
