This studyis part of a collaborativeeffortbetweenMontanaTechand AtlanticRichfield Companyto find solutions for treating metal-contaminated surface runoff from the surrounding city of Butte, Montana. The runoff flows into a storm drai% which transports the suspended and dissolved metals into nearby Silver Bow Creek, a tributary of the Clark Fork River. The study compared percent removal of metrd...

This paper reports on hydrocarbon-degrading microbial consortia immobilized in biofilms on gravel particles in the intertidal zone of the Arabian Gulf coast. These microorganisms contribute to the self-cleaning of the coasts and, in addition, could potentially be used for cleaning oily industrial waste before its disposal in the open environment. Each gravel particle was found coated with about...

In this work we demonstrate the potential of permanent magnet based magnetic resonance sensors to monitor and assess the extent of pore clogging in water filtration systems. The performance of the sensor was tested on artificially clogged gravel substrates and on gravel bed samples from constructed wetlands used to treat wastewater. Data indicate that the spin lattice relaxation time is linearl...

Sediment-maintenance flushing flows designed to mimic the action of natural floods in removing the accumulated fine sediments from the channel and loosening the gravel bed have been increasingly proposed as an effective alternative in dam management and a required component of riverine restoration programmes. However, reservoir releases are generally associated with financial and environmental ...

An experiment with different filter beds and macrophytes was carried out to study their phytoremediation capacity on the efficiency of domestic wastewater treatment through constructed wetland (CW) from November March 2017-18 at University Agricultural Sciences, Dharwad campus, Karnataka. Twenty combinations involving five types (FB-1: gravel, FB-2: gravel-sand-gravel, FB-3: gavel-sand-brick-gr...

A diverse flora has been discovered in a dark clay lens in upland gravel in southern Maryland near Brandywine. More than 49 taxa have been identified in the assemblage, which includes leaves, seeds, fruits, pollen, and a Taxodium (bald cypress) trunk. The vegetation is dominated by deciduous trees and vines. Four taxa are now absent from North America but survive elsewhere; one is extinct. A la...

The study was aimed to evaluate the selected improvements of nature restoration in a depleted gravel pit. The study site consisted of four water reservoirs of different shapes and sizes, flooded after the gravel extraction ended. Ecological succession monitoring, conducted by the Warsaw University of Life Sciences students associated in the Student Scientific Association of Animal Sciences Facu...

We report gravel of the River Euphrates, capped by basalt that is Ar-Ar dated to ∼9 Ma, at Shireen in northern Syria. This gravel, preserved by the erosion-resistant basalt, allows us for the first time to reconstruct the history of this major river during the Late Miocene. In response to progressive regional surface uplift, the Euphrates extended SE by ∼800 km between the early Middle Miocene,...
