The gypsum karst of Italy [PDF]

open access: yesInternational Journal of Speleology, 1996
Gypsum karst has been studied in Italy since the last decades of the l9th Century. In 1917 the geographer Olinto Marinelli published Fenomeni carsici delle regioni gessose d Italia , a fundamental synthesis of the early research.

Ugo Sauro: Highlights of some human adventures in a karst environment: the case of the Monti Lessini (Venetian Prealps, Italy)

open access: yesActa Carsologica, 2017
The Monti Lessini, a mountain group located north of the town of Verona, has been the scene of many different human adventures, some of them related to the local karst environment and features.

Investigating the Factors Influencing on the Formation and Development of Karstic in Darparchin Basin in the North East of Iran [PDF]

open access: yesجغرافیا و توسعه, 2017
Areas of the earth, which are covered by limestone formations and dissolved by  water flows, are called karst areas. Due to the fact that karst forms play an important role in water resources, tourism and development activities, their study is considered

Karst Vadose Zone Hydrology Explored Through Cave Drip Water Dynamics: The Roles of Soil, Epikarst and Climate

open access: yesHydrological Processes, Volume 40, Issue 6, June 2026.
Cave drip rate monitoring in Nova Grgosova Cave reveals three types of drip sites: (1) predominantly constant, (2) seasonally varying and (3) mostly constant with occasional sharp increases. The observational data coupled with one‐dimensional water‐balance model demonstrates that evapotranspiration and soil–epikarst storage, rather than precipitation ...

Uncertainties associated with the use of erosional cave scallop lengths to calculate stream discharges

open access: yesInternational Journal of Speleology, 2020
Scallops are extremely valuable indicators of past water flows in caves because they often record events that cannot be safely witnessed nor measured. Qualitatively, the inverse relationship between their lengths and formative water velocities is useful ...

Simulation of Soil Water Content in Clayey Soils Where Dissolution and Precipitation of Pedogenic Carbonates Impact the Accuracy of Sensors Measuring Soil Water Content

open access: yesHydrological Processes, Volume 40, Issue 6, June 2026.
This study deals with limitations of frequency domain reflectometry sensors, including data drift, when monitoring clayey soils with pedogenic carbonates. Despite these inaccuracies, the results demonstrate that corrected measurements of soil water content can still successfully calibrate hydrological models.

Oases of endemism: Regional aquifer desert springs serve as biodiversity hotspots preserving vulnerable endemic taxa in the Great Basin and Mojave Desert regions

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts ...

Regional Patterns and Regulatory Mechanisms of Aquatic Carbon Transfer in China

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Inland waters constitute vital components in the global carbon (C) cycle. Nevertheless, the regional patterns of aquatic carbon transfer across China remain poorly quantified, and their impacts on the terrestrial carbon budget remain unclear.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.
