Modelling the hydrological process of the karst spring using a revised Vensim model

open access: yes地质科技通报, 2022
The conventional Vensim model uses two parallel reservoirs to simulate the slow and fast flows in karst systems, which can hardly simulate the existing nonlinear hydrological process.

The initial stages of cave formation: Beyond the one-dimensional paradigm

open access: yes, 2010
The solutional origin of limestone caves was recognized over a century ago, but the short penetration length of an undersaturated solution made it seem impossible for long conduits to develop.

Classification and characteristics of karst reservoirs in China and related theories

open access: yesPetroleum Exploration and Development, 2009
Karst reservoirs are distributed widely in China, for which integrated geological, logging, testing, and seismic identification marks can be made and their ages can be determined using unconformity surfaces, the lithologic features, and paleobiology of ...

New Method for Characterizing Internal Structure of Fault-Karst Reservoirs and Analysis on Acidizing Fracturing Effect: A Case Study in HLHT Oilfield, Tarim Basin, NW China

open access: yesLithosphere, 2021
Superimposed tectonic movement and karst erosion resulted in a combination of fractures and irregular caves in deep/ultradeep carbonate rocks, typically along major fault swarms.

Reactive-infiltration instabilities in rocks. Fracture dissolution

open access: yes, 2012
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surrounding rock matrix.

Climate change and its influence on the Karst groundwater recharge in the Jinci Spring Region, Northern China [PDF]

open access: yes, 2017
Due to climate change and human activities over the last fifty years, the spring flow volume of karst groundwater has sharply diminished in China. Climate change is one of the critical factors that initiates a series of karst hydrogeologic and water ...
