Evaporite karst geohazards in the Delaware Basin, Texas: review of traditional karst studies coupled with geophysical and remote sensing characterization [PDF]

open access: yes, 2017
Evaporite karst throughout the Gypsum Plain of west Texas is complex and extensive, including manifestations ranging from intrastratal brecciation and hypogene caves to epigene features and suffosion caves.

Spatial Markov Model of Advective‐Diffusive Transport in Heterogeneous Domains

open access: yesWater Resources Research, Volume 62, Issue 1, January 2026.
Abstract Spatial Markov models (SMM) are an efficient approach to simulate transport in heterogeneous media across scales. They represent particle transport by equidistant spatial transitions with correlated random velocities, which renders the associated transition times correlated random variables.

Evaporite sinkholes of the Friuli Venezia Giulia region (NE Italy) [PDF]

open access: yes, 1991
Sinkholes are common in the Friuli Venezia Giulia (FVG) Region (NE Italy), where the presence of karstifiable rocks favours their occurrence accelerated by intense rainfalls.

Hydrochemistry and stable isotopes (δ 18 O and δ 2 H) tools applied to the study of karst aquifers in Southern Mediterranean basin (Teboursouk area, NW Tunisia) [PDF]

open access: yes, 2018
Karst aquifers receive increasing attention in Mediterranean countries as they provide large supplies water used for drinkable and irrigation purposes as well as for electricity production.

The creation of collapse dolines: A 3D modeling approach

open access: yesActa Carsologica, 2014
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.

Preliminary validation of an indirect method for discharge evaluation of Pertuso Spring (Central Italy) [PDF]

open access: yes, 2016
This paper deals with the results of the first year of the Environmental Monitoring Plan, related to the catchment project of Pertuso Spring, which is going to be exploited to supply an important water network in the South part of Roma district.

Detection of Karst Features in the Black Hills Area in South Dakota/Wyoming, USA, Based on Evaluations of Remote Sensing Data [PDF]

open access: yes, 2018
Landsat 8, Sentinel 2, Aster, RapidEye and PlanetScope data and Sentinel 1- and Advanced Land Observing Satellite (ALOS)-Phased Array type L-band Synthetic Aperture Radar (PALSAR)-radar images have been evaluated for a karst feature inventory in the ...

Vegetation cycles in a disturbed sequence around the Cobb-Mountain subchron in Catalonia [PDF]

open access: yes, 2008
A 52 m-long lacustrine sequence has been recovered from the basin of Bòbila-Ordis, near Banyoles (N-E Spain). The presence of Early Biharian rodent teeth (Early Pleistocene) and of a c.

Emergence of Tri-Phasic Muscle Activation from the Non-linear Interactions of Central and Spinal Neural Network Circuits [PDF]

open access: yes, 1991
The origin of the tri-phasic burst pattern, observed in the EMGs of opponent muscles during rapid self-terminated movements, has been controversial. Here we show by computer simulation that the pattern emerges from interactions between a central neural ...
