Human impacts to mountain streams

Geomorphology, 2006
Mountain streams are here defined as channel networks within mountainous regions of the world. This definition encompasses tremendous diversity of physical and biological conditions, as well as history of land use. Human effects on mountain streams may result from activities undertaken within the stream channel that directly alter channel geometry, the

The mountain stream of infant development

Infancy, 2023
AbstractDevelopment is complex. It encompasses interacting domains, at multiple levels, across nested time scales. Embracing the complexity of development—while addressing the challenges inherent to studying infants—requires researchers to make tough decisions about what to study, why, how, where, and when.

A mountain stream flowmeter

Flow Measurement and Instrumentation, 2002
Abstract A new method of continuously gauging the flow in steep mountain torrents has been investigated. Seismic vibrations in the bedrock, resulting from the tumbling water flowing in a mountain stream, have been recorded from a site in north Wales and have been compared to direct current meter flow measurements over a wide range of flow conditions.

Iron Photoreduction and Oxidation in an Acidic Mountain Stream

Science, 1988
In a small mountain stream in Colorado that receives acidic mine drainage, photoreduction of ferric iron results in a well-defined increase in dissolved ferrous iron during the day. To quantify this process, an instream injection of a conservative tracer was used to measure discharge at the time that each sample was collected.

Dispersion in Mountainous Natural Stream

Journal of the Environmental Engineering Division, 1982
A chronological and critical review is made of existing methods for predicting coefficients and the area of the longitudinal turbulent dispersion, which were chosen by their importance and applicability to open natural streams. For natural mountain streams, a suitable method for calculating dispersion coefficient on the basis of flow parameters is ...

Nitrogen transformations in a small mountain stream

Hydrobiologia, 1985
Ammonium, urea, and nitrate were added to Bear Brook, a second and third order stream in the Hubbard Brook Experimental Forest, New Hampshire. Removal of ammonium and urea during downstream transport coincided with the release of nitrate. Nitrate removal did not occur when it was added alone or with dissolved organic carbon.

Channel geometry of mountain streams

2011
Channel networks in the glaciated mountain basins of Coastal and southern interior British Columbia (Ashnola River Basin) offer opportunities for morphometric studies relating the parameters of the flow area (A) - discharge (Q) relationship to readily available channel and basin parameters.

Streams and Sources, Forests and Mountains

2016
The history of Ch’an/Zen and the Thai Forest Tradition is told from their respective genesis stories. The actions and attitudes of Bodhidharma and Mun and their immediate disciples are identified as revivalist rebels. In the case of the forest monks, their history as a general social movement is traced to the earliest days of the sangha in India and ...
