Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...

Sinkhole Physical Models to Simulate and Investigate Sinkhole Collapses

Sinkholes and the Engineering and Environmental Impacts of Karst: Proceedings of the Fourteenth Multidisciplinary Conference, 2015
Florida is one of the most susceptible states for sinkhole collapses due to its karst geology. In Florida, sinkholes are mainly classified as cover subsidence sinkholes that result in a gradual collapse with possible surface signs, and cover collapse sinkholes, which collapse in a sudden and often catastrophic manner.

Interpreting a Legacy Fossil Assemblage Excavated From Waribruk (New Guinea II Cave), GunaiKurnai Aboriginal Country, Snowy River National Park, Southeastern Australia

Archaeology in Oceania, Volume 61, Issue 2, Page 253-276, July 2026.
ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

A Statistical‐Process Hybridized Approach to Modeling Permafrost Distribution in a Boreal Wetland Ecosystem, Whatì, NT, Canada

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 323-341, July/September 2026.
ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.

Hydrogeochemical processes controlling water and dissolved gas chemistry at the Accesa sinkhole (southern Tuscany, central Italy)

Journal of Limnology, 2014
The 38.5 m deep Lake Accesa is a sinkhole located in southern Tuscany (Italy) that shows a peculiar water composition, being characterized by relatively high total dissolved solids (TDS) values (2 g L-1) and a Ca(Mg)-SO4 geochemical facies.

North Pacific Extreme Storms Reconstructed With a Novel Approach to Estimating Storm Frequency and Uncertainty

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Sedimentary archives of tropical cyclones have been primarily developed in back barrier settings and karst basins at low to mid‐latitude sites in the Atlantic. Here, a unique record of high‐latitude storms is presented from Skan Bay, Unalaska in the Eastern Aleutian Islands. Storm‐induced coarse deposits in a 20.5 m composite sediment core are

Quantifying the Role of Karst Groundwater on Mountain River Discharge

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract In snow‐fed, mountainous karst regions, aquifers sustain and are connected to streamflow via springs and distributed groundwater exchanges (DGE) including inflows (DGI) and losses (DGL). Despite their significance, there is limited understanding of the complex flow paths linking aquifers and streams, particularly regarding flow path source and

Post‐Eruptive Deformation and Faulting Caused by Dike Channel Retraction, Material Drain‐Back and Contraction of the 2021 Tajogaite Craters (La Palma)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Young scoria cones fed by dike channels or conduits may undergo rapid and substantial post‐eruptive morphological modification; however, the structural controls and mechanisms governing topographic degradation remain poorly constrained. This knowledge gap limits our ability to reliably interpret topography, faults, deposits and the evolution ...

Some human actions in the destruction and construction of culture and nature – the Merafong region as a case study

The Journal for Transdisciplinary Research in Southern Africa, 2006
For at least the past 180 years the Merafong Municipal region in the Gauteng Province of South Africa, (of which the Wonderfontein Catchment forms a part) has strongly relied on the primary sector for its economic existence and development.
