Role of sediment in speleogenesis; sedimentation and paragenesis [PDF]

open access: yesGeomorphology, 2011
Although the effects of sedimentation in caves have been recognised for many years, its role in speleogenesis is frequently overlooked. Influxes of sediment into a cave system fundamentally alter the way cave passages develop, either by alluviation in a vadose environment, forcing lateral corrosion and the development of notches, or by upwards ...

The in vitro influence of the burrowing polychaete Nereis diversicolor on the fate of petroleum hydrocarbons in marine sediments [PDF]

open access: yes, 1994
The in vitro fate of the saturated hydrocarbon fraction (SF) of Arabian Light crude oil has been studied in PVC cores filled with a coastal marine sediment defaunated by sieving.

Supercarriers of antibiotic resistome in a world’s large river

open access: yesMicrobiome, 2022
Background Antibiotic resistome has been found to strongly interact with the core microbiota in the human gut, yet little is known about how antibiotic resistance genes (ARGs) correlate with certain microbes in large rivers that are regarded as ...

Soil carbon and nitrogen erosion in forested catchments: Implications for erosion-induced terrestrial carbon sequestration [PDF]

open access: yes, 2015
Lateral movement of organic matter (OM) due to erosion is now considered an important flux term in terrestrial carbon (C) and nitrogen (N) budgets, yet most published studies on the role of erosion focus on agricultural or grassland ecosystems.

A Machine Learning Model Relating Xrain and Rain Gauge

open access: yesProceedings, 2022
In the last decade, rainfall radars have been deployed at volcanoes such as Mt. Merapi in Indonesia and can even cover a whole country such as in Japan, where the X-Rain (eXtended Radar Information network) product has been available for local research ...

Trends of surface humidity and temperature during 1951−2012 in Beijing, China [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
In this paper, two datasets, a long time series (1951–2012) of daily surface observations at one meteorological station and a shorter time series (1979–2012) of three-hourly data with 0.1°×0.1° spatial resolution were analysed by using non-parametric ...

Study on the influence of industrial structure optimization on water environment and economy: A case study of Changzhou city

open access: yesFrontiers in Earth Science, 2023
Economic development and large amounts of industrial production have led to environmental deterioration. The assessment and prediction of water environment capacity (WEC) are crucial supports for water quality target management.

Study on Ecological Scheduling of the Xiaolangdi Reservoir Based on the Ecological Needs of Estuarine Fishes

open access: yesMATEC Web of Conferences, 2018
The total water amount into the Yellow River estuary is significantly reduced with the construction of a series of reservoirs in the Yellow River, which has a lot of adversely effects on the fishes and fishery resources in the estuary.

The Hydrodynamic Characteristics Induced by Multiple Layouts of Typical Artificial M-Type Reefs with Sea Currents Typical of Liaodong Bay, Bohai Sea

open access: yesJournal of Marine Science and Engineering, 2021
Artificial reefs are effective measures to improve the marine ecological environment and increase fishery production. However, there are several geometries being investigated nowadays and their setup, including the spacing between groups of them, can ...

A physical model for seismic noise generation from sediment transport in rivers [PDF]

open access: yes, 2012
Measuring sediment flux in rivers remains a significant problem in studies of landscape evolution. Recent studies suggest that observations of seismic noise near rivers can help provide such measurements, but the lack of models linking observed seismic ...
