Traditional slope calculation algorithms cannot accurately predict river slopes as these are based on cell-by-cell calculation, which is only suitable for hillslopes and small mountainous streams.
Identified sources of contamination could be useful to local authorities for the control of surface water pollution and the obtained results will help to design a future spatial sampling strategy in an optimal manner for mountainous streams of the region.
Because land use transformation and removal of wooded riparian areas increase clogging and simultaneously reduces the input of CPOM, our findings stress the importance to include the management of river basins in the conservation strategies of mountainous streams.
In this study we investigated the effect of near streambed turbulence in terms of turbulent kinetic energy (TKE) on the composition and architecture of biofilms matured in two mountainous streams differing in dissolved nutrient concentrations.
Local police, who declined to comment further on the Sept. 24 killing near the town of Haverstraw, have been unable to find Palmer, an experienced outdoorsman, despite a search of Harriman Park's 46,000 acres (19,000 hectares) of mountainous woods, streams, lakes and caves.
It is triangular, rugged, and mountainous, with many streams and fertile soils.
In a 2008 episode of the BBC's Life in Cold Blood, Attenborough encountered this bright yellow poisonous frog as it wrestled and courted females in the mountainous tropical forest streams of El Vallé de Anton in Panama, and demonstrated the endearingly unique wave it uses to communicate.
Rivers are an important source of CO2 to the atmosphere, however, mountainous rivers and streams with high emission rates are not well studied particularly in China.
Our calculated CO2 areal fluxes were in the upper-level magnitude of published data, demonstrating the importance of mountainous rivers and streams as a global greenhouse gas source, and urgency for more detailed studies on CO2 degassing, to address a global data gap for these environments.
To understand the importance of non-free ionic fractions (NIF) of major metals in freshwater streams, Na, Mg, Ca, silicon (Si), and fulvic acid-like materials (FAM) were measured in streams of mountainous adjacent headwater catchments dominated by different vegetation types (planted evergreen coniferous forest and natural deciduous broadleaf forest).
