Bistability in a simple fluid network due to viscosity contrast

, 2010
We study the existence of multiple equilibrium states in a simple fluid network using Newtonian fluids and laminar flow. We demonstrate theoretically the presence of hysteresis and bistability, and we confirm these predictions in an experiment using two ...

Analysis of the influence of tunnel engineering on groundwater resources in karst mountain areas: A case study of a tunnel in Wushan county of Chongqing City

Carsologica Sinica
Tunnel construction can disrupt the groundwater balance, impacting the drainage of both surface water and groundwater, as well as causing other eco-environmental effects. This study takes a water-diversion tunnel as the research object.

Hazards caused by natural and anthropogenic changes of catchment area in karst

, 2004
International audienceDetermination of the catchment area is the starting point in most hydrological analyses. It serves as a basis for many hydrological and water resources management calculations. The catchment boundaries and areas in karst regions are

A new method for predicting the oil displacement volume by waterflood huff-puff of the fractured-cavity type carbonate oil reservoirs

Frontiers in Energy Research
Introduction: More than two billion tons of oil reserves have been discovered in the fractured-cavity type carbonate reservoirs in Tarim Basin, which is a key field for increasing reserves and production in the future.

Optimization of Development Strategies and Injection-Production Parameters in a Fractured-Vuggy Carbonate Reservoir by Considering the Effect of Karst Patterns: Taking C Oilfield in the Tarim Basin as an Example

Energies
The spatial structural characteristics of fractured-vuggy units vary greatly in different karst patterns, which significantly influence the study of remaining oil distribution patterns in ultra-deep fractured-vuggy reservoirs and the determination of the

Infiltration processes in karst using an event-based conceptual model of flow and transport of dissolved organic carbon

, 2011
International audienceThe aim of this study is to characterize karst infiltration processes during flood events using a rainfall-discharge model coupled with a transport model for non-conservative solutes.
