Physics and Chemistry of Dissolution on Subaerialy Exposed Soluble Rocks by Flowing Water Films
Wolfgang Dreybrodt, Georg Kaufmann
Ni določena
Oznake:
The basic process active in the formation of subaerial features on karst rocks is chemical dissolution of limestone or gypsum by water films flowing on the rock surface. The dissolution rates of limestone and gypsum into thin films of water in laminar flow are given by F = α(ceq-c), where (ceq-c) i ...

Modelling speleogenesis in soluble rocks: A case study from the Permian Zechstein sequences exposed along the southern Harz Mountains and the Kyffhäuser Hills, German
Georg Kaufmann, Douchko Romanov
Izvirni znanstveni članek
Oznake:
Soluble rocks such as limestone, dolomite, gypsum, anhydrite, and salt can be dissolved by water flowing through voids in the rocks. The removal of the dissolved material from fissures and bedding partings by physical and/or chemical dissolution enlarges the permeability of the soluble rocks within ...

Modelling flow of subterranean Pivka river in Postojnska jama, Slovenia
Georg Kaufmann, Franci Gabrovšek, Janez Turk
Izvirni znanstveni članek
Oznake: modelling;hydrology;Postojnska jama
The sub-surface flow path through the Postojnska jama cave system has been monitored with 7 stations distributed along the flow path, monitoring stage and temperature. We have used the stage data to model flow through the cave system with the program package SWMM, simulating the active parts of Post ...

Fracture evolution in soluble rocks: From single-material fractures towards multi-material fractures
Georg Kaufmann, Douchko Romanov, Franci Gabrovšek
Izvirni znanstveni članek
Oznake: soluble rock;single fracture;dissolution and precipitation;inception horizon
We employ a numerical model describing the evolution of secondary porosity in a single fracture embedded in soluble rock (limestone, gypsum, and anhydrite) to study the evolution of isolated fractures in different rock types. Our main focus is three-fold: The identification of shallow versus deep fl ...

The creation of collapse dolines: A 3D modeling approach
Thomas Hiller, Douchko Romanov, Franci Gabrovsek, Georg Kaufmann
Izvirni znanstveni članek
Oznake:
We present a 3D numerical karst evolution model describing mechanisms governing the evolution of collapse dolines. The results confirm the current state of the art of the knowledge about the conditions necessary for a collapse doline to grow. We demonstrate that these geological features develop in ...
