Time-averaged flow structure in the central region of a stream confluence
Carrying capacity ; Channel geometry ; Confluent ; Fluvial dynamics ; Fluvial hydrology ; Illinois ; Runoff ; Stream flow ; United States of America
This paper examines the time-averaged, two-dimensional (downstream and cross-stream) flow sructure within the central region of the confluence hydrodynamic zone (CHZ) at a small stream confluence with an asymmetrical planform. It also examines how
On the nature of spatial and temporal variations of bedload transport in a gravel-bed stream
Carrying capacity ; Flood ; Fluvial hydrology ; Montana ; Mountain ; Rocky Mountains ; Roughness ; Seasonal variation ; Sediment load ; Stream ; Stream flow ; United States of America
To obtain an understanding of the hitherto unknown high resolution, continual temporal and spatial nature of bedload transport in gravel-bed streams, measurements were undertaken over 2 magnetically sensitive bedload detector logs at Squaw Creek
Reaeration of a low-gradient tropical rainforest stream in the Amazon Basin of Peru
Amazonas River ; Deforestation ; Ecosystem ; Forest ; Heavy metals ; Human impact ; Oxygen ; Peru ; Riparian vegetation ; Stream ; Tropical rain forest ; Water quality
This study is an investigation of the processes of integration of the atmospheric, hydrologic, biologic, and geologic environmental subsystems that interact to maintain a dissolved oxygen flux in a first-order stream in the Amazon rainforest. Stream

transport events associated with the daily rise and fall in stream discharge were investigated. This paper reports the results of this study designed to describe fully the adjustment of river bed and turbulent flow to the unsteady passage of a pebble bedload.
Australia ; Braided channel ; Carrying capacity ; Channel geometry ; Riparian vegetation ; Sand ; Stream ; Stream flow ; Tropical zone ; Western Australia
This paper examines the existence of sand-dominated ridge-form anabranching rivers in the Kimberley region of Western Australia. It describes their channel and ridge morphology, sedimentology and stratigraphy, discusses stream flow and sediment
Nature and dynamics of an active block stream, Kunlun pass, Qinghai Province, People's Republic of China
Block stream ; China ; Grain size distribution ; Meltwater ; Mountain ; Periglacial features ; Permafrost ; Qinghai ; Slope dynamics ; Soil moisture ; Soil temperature
This paper describes the results of a five-year study of the physical characteristics and movement of an active rock stream on the north slope of the Kunlun Shan whose thermal regime was previously described. It appears that the surface blocks tend
Dambreak flood impact on mountain stream bedload transport after 13 years
Carrying capacity ; Catastrophe ; Colorado ; Flood ; Grain size distribution ; Impact ; Mountain ; Sediment transport ; Stream ; United States of America
The aim of this study is to simulate the uncertainty that arises from using the law of the wall in shallow streams, using a specific case-study to assess the extent to which estimates could be in error. More particularly, the effects on bed shear
Where along a river's length will vegetation most effectively stabilise stream banks?
Australia ; Bank erosion ; Channel geometry ; Floodplain ; Mass movement ; Meander ; Riparian vegetation ; River bed ; Stream ; Vegetation ; Victoria ; Watershed
This paper describes the scale analysis approach as applied to the Latrobe River in Gippsland, Victoria, Australia. It illustrates a structured decision-making approach for assessing the role of vegetation in stream bank erosion at different points
Catastrophic landslides and their effects on the Upper Indus streams, Karakoram Himalaya, northern Pakistan

of meters of the Upper Indus stream valleys have been dominated by epicycles of aggradation, trenching, and downcutting that mainly reflect the scale, timing and history of each barrier. The landforms involved are only indirectly related to the late-glacial

there are also three (floodplain, flood channel, low-water channel). Combinations of these three categories define the diversity of patterns. The critical stream power values and hydrological regime together define the channel pattern, and analysis of the pattern
