Researchers have devised a better way to measure how fast sediment flows in rivers -- information that can help scientists and planners better prepare for flooding and weather-related events, ...

Many high-mountain rivers in Asia transport more sediment downstream compared to a few years ago. Changes in sediment levels have a particularly strong impact on agriculture, water quality, flood ...

Channel morphology in streams and rivers is a product of the watershed scale flux of sediment and water to the channel network. As a result the scaling of channel geometry downstream through stream ...

Journal of Urban and Environmental Engineering, Vol. 2, No. 1 (January to June, 2008), pp. 28-32 (5 pages) Abstract: The present work is a comparative evaluation of some of the well known sediment ...

The bed roughness in headwater streams is generally large in comparison to the flow depths required to initiate bed load transport The roughness produced by cobbles and gravels distorts the vertical ...

Soluble reactive phosphorus (SRP) transport/retention was determined in two rain forest streams (Salto, Pantano) draining La Selva Biological Station, Costa Rica. There, SRP levels can be naturally ...

The dry-looking stream in your backyard may play a major role in feeding U.S. rivers. Channels that flow only in direct response to weather conditions like heavy rain, called ephemeral streams, on ...
