Effect of Gravel on Soil Porosity and Water Infiltration of Lime Soil in Southwest Karst Area
Shuitu Baochi Xuebao[Objective] Gravel is an important factor affecting soil porosity and water infiltration. Therefore, it is of great significance to determine the specific soil porosity characteristics that are impacted by gravel-induced changes.

Biological Reviews, EarlyView.ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Exploring Relationships Between Karst Terrains and Social Features by the Example of Gömör-Torna Karst (Hungary-Slovakia) [PDF]
, 2015 Human-environment relations have some special characteristics on karst terrains, and karstlands are usually less densely inhabited areas principally due to hydrologic, topographic and pedologic reasons.

Karst Geomorphology at Moira River, Ontario [PDF]
, 1986 This is the first study of the karst features found at Moira River karst. This study intends to investigate a number of different karst features of the area rather than concentrating on one highly specific problem.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas
Deep Underground Science and Engineering, EarlyView.This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Deep Underground Science and Engineering, EarlyView.To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...
