A start up in Ecuador is using a conveyor belt to skim off and remove plastic from rivers and working to stop polluters adding plastic to rivers in the first place
It is also likely that DOC removal is highly variable in space and time and DOC removal rates in streams and rivers depend on the lability of DOC inputs in addition to environmental conditions that regulate microbial activity [Raymond et al 2016] Nonetheless our modeling exercise allows us to identify a plausible value of DOC uptake at the
River surface cleaning work involves collection of all kinds of floating matter in river by employing motorized machine/ equipment The motorized machine is called as Trash Skimmer The waste collected by Trash skimmer shall be disposed off at specified location on shoreline The collection transportation and disposal of waste shall be in
Ecological remediation is one of the most practical methods for removing nutrients from river ecosystems In this study transformation and fate of nitrate and ammonium among four different ecological restoration treatments were investigated by stable 15N isotope pairing technique combined with quantitative polymerase chain reaction and high throughput

The Elastec Brute Boom is a heavy duty debris containment boom for surface and submerged trash litter natural debris and large floating objects in rivers reservoirs oceans and lakes Brute Bin The purpose of the Elastec Brute Bin is to capture floatables from stormwater conveyances and outfalls before they reach our waterways
The spatio temporal dynamism of sediment discharge Qs in rivers is influenced by various natural and anthropogenic factors Unfortunately most rivers are only monitored at a limited number of stations or not gauged at all Therefore this study aims to provide a remote sensing based alternative for Qs monitoring The at a station hydraulic geometry AHG power law
Streams and rivers play a major role in the global carbon cycle as they collect transform and deliver terrestrial organic carbon to the ocean The rate of dissolved organic carbon DOC removal depends on hydrological factors primarily water depth and
Dissolved organic carbon DOC in large river networks is an important carbon pool in the global biogeochemical cycle DOC compositions vary spatially at global and regional scales which influences DOC degradation and subsequent in stream removal in river networks The Changjiang River Network CRN is the third largest river system worldwide and plays an
