Spatio-temporal dynamics and drivers of drying conditions in the HRB: Unraveling the role of precipitation intensity and total precipitation in drying risk

Journal of Hydrology: Regional Studies
Study region: The Hangbu River Basin (HRB), located in eastern China, is the largest sub-basin of the Chaohu Lake Basin. Study focus: In recent decades, the HRB has experienced increased drying and spatial heterogeneity in its hydrological conditions ...

Modeling the evolution of natural cliffs subject to weathering. 2, Discrete element approach [PDF]

, 2011
The evolution of slopes subjected to weathering has been modeled by assuming Mohr-Coulomb behavior and by using a numerical approach based on the discrete element method (DEM).

Integrated modeling of blue and green water evolution in a headwater region of Chaohu Lake: Impacts of climate and surface environmental factors

Ecological Indicators
Understanding the dynamic changes of blue water (BW, surface and groundwater) and green water (GW, soil-stored rainfall used by plants via evapotranspiration) is essential for assessing water resource sustainability.

Elemental data for Gonghai Lake sediments show significant effects of human activities on weathering processes after 1550 CE

Frontiers in Earth Science, 2023
The international Anthropocene Working Group has recognized the mid-20th centrury (ca. 1950 CE) as the onset of the Anthropocene, but human activities in China altered the land cover and influenced weathering processes much earlier.

Sensitivity of the global carbonate weathering carbon-sink flux to climate and land-use changes [PDF]

, 2019
The response of carbonate weathering carbon-sink flux (CCSF) to its environmental drivers is still not well understood on the global scale. This hinders understanding of the terrestrial carbon cycle.

Relationship between mineralogy and the physico-chemical properties of till in central Finland [PDF]

Bulletin of the Geological Society of Finland, 1992
The chemical and physical characteristics of the fine fraction of till were examined in the area of the Raahe-Ladoga metallogenic belt in central Finland. Till, weathered bedrock and rock samples were collected from the area, where element concentrations

The Effect of Aspect and Elevation on Critical Zone Architecture in the Reynolds Creek Critical Zone Observatory: A Seismic Refraction Study

Frontiers in Water, 2021
In the northern hemisphere within snow-dominated mountainous watersheds north-facing slopes are commonly more deeply weathered than south-facing slopes. This has been attributed to a more persistent snowpack on the north facing aspects.

Chemical weathering and provenance evolution of Holocene–Recent sediments from the Western Indus Shelf, Northern Arabian Sea inferred from physical and mineralogical properties [PDF]

, 2012
We present a multi-proxy mineral record based on X-ray diffraction and diffuse reflectance spectrophotometry analysis for two cores from the western Indus Shelf in order to reconstruct changing weathering intensities, sediment transport, and provenance ...

Hydrologic Transport of Dissolved Inorganic Carbon and Its Control on Chemical Weathering [PDF]

, 2017
Chemical weathering is one of the major processes interacting with climate and tectonics to form clays, supply nutrients to soil microorganisms and plants, and sequester atmospheric CO2.
