Water and mud inrush is one of the most important geohazards in underground engineering.
The paper presents a state-of-the-art review of the current understanding of this type of …

Due to a lack of awareness of environmental protection at the beginning of tunnel
excavation and the unique ecological vulnerability of karst areas, tunnel excavation is …

Geological hazards, particularly water inrush, pose frequent challenges in tunnel
constructions within karst regions. Drawing from the engineering experiences in addressing …

Water and mud/rock inrush has been recognized as one of the major geological hazards in
underground engineering, which resulted in huge casualties, financial losses, or …

We present a discussion of the state-of-the art on modelling geometrical characteristics,
hydrogeological behavior and geochemical evolution of karst aquifers of meteoric origin …

The groundwater drawdown caused by tunnel excavation can change the hydrogeological
flow system in karst areas. However, how to overcome the heterogeneity in karst aquifers …

Water inrush is a major hidden danger that decreases coal mining safety. Thus, preferential
flowpaths of water inrush in mining areas must be investigated to prevent water disasters …

Breakthrough curves (BTCs) are known as adequate evidence to characterize karst aquifers
which mainly specified by dual flow systems (matrix and conduit) as well as some degree of …

Protecting karst aquifers from nitrate contamination is an issue of global concern due to the
inherent vulnerability of karst aquifers to contamination and the negative health effects of …

Using the reservoir model theory, this study developed an equation for the relationship
between the transfer and recession coefficients under a matrix-restrained flow regime …
