Rapid assessment of water and mud inrush likelihood in karst tunnels based on decision tree model: A case in Siding tunnel of Guihe expressway

Carsologica Sinica
With the ongoing advancement of infrastructure projects, such as highways and railways, in China, karst tunnel construction is increasingly evolving towards longer, larger, and deeper dimensions. The problem of water and mud inrush in tunnels is becoming

MEVTV Workshop on Tectonic Features on Mars [PDF]

The state of knowledge of tectonic features on Mars was determined and kinematic and mechanical models were assessed for their origin. Three sessions were held: wrinkle ridges and compressional structure; strike-slip faults; and extensional structures ...

Study on the identification of karst surface collapse via UAV photography based on the YOLO model

Discover Applied Sciences
Surface collapse is a relatively common geological disaster in karst areas, characterized by sudden occurrence and continuous development. Large-scale ground construction operations need to identify it in advance to reduce its adverse effects. This paper,

Karst [poster] [PDF]

, 2005
Florida’s geology allows for the creation of many interesting features including sinkholes, underground rivers, springs, and caves. These features make up what is called karst topography which forms as flowing water slowly dissolves the limestone and ...

Distinguishing Areas of Cave Collapse: A Case Study Applied to Carter Caves State Resort Park, Kentucky, USA

Geosciences
While dissolution dominates the genesis of karst systems, physical erosion processes also play a significant role in their development. Lowering of the water table exposes caves to vadose conditions, reducing roof-supporting buoyancy and potentially ...
