A Method for Extracting Stream Channel Flow Paths from LiDAR Point Cloud Data
LiDAR Point Cloud Streams
2015/8/14
Traditional methods of delineating stream channel networks use gridded raster elevation data. Direct use of LiDAR point clouds, without first creating a raster or grid, could improve efficiency and ac...

Fuzzy rule-based model for contaminant transport in a natural river channel
Fuzzy rule-based model contaminant transport natural river channel
2009/12/4
Fuzzy rules are used to model solute dispersion in a river dead zone, such that the turbulent diffusion is determined by a fuzzy inference system which relates the local mean velocity shear to the lon...
Fuzzy rules based model for solute dispersion in an open channel dead zone
Fuzzy rules based model solute dispersion open channel dead zone
2009/12/4
A method has been developed to estimate turbulent dispersion based on fuzzy rules that use local transverse velocity shears to predict turbulent velocity fluctuations. Turbulence measurements of flow ...
THREE-DIMENSIONAL STABILITY ANALYSIS OF OPEN CHANNEL FLOW OVER AN ERODIBLE BED
THREE-DIMENSIONAL STABILITY ANALYSIS OPEN CHANNEL FLOW ERODIBLE BED
2009/10/29
The formation oP ripples and dunes (lower range bed waves) is assumed to
be related to the transport of sediment as bed load. From the present
theory it is concluded that the formation of the upper ...
CHANNEL EROSION IN THE OPA BASIN, SOUTHWESTERN NIGERIA
topographic attributes channel sediment OPA BASIN
2009/10/12
This study examines the relationship between topographic attributes and channel sediment yield in nineteen 1st order, five 2nd order, one 3rd order and one 4th order river basin under different land u...
Salt intrusion in multi-channel estuaries：a case study in the Mekong Delta, Vietnam
multi-channel estuaries Mekong Delta Salt intrusion
2009/5/15
There is a well-tested theory for the computation of salt intrusion in alluvial estuaries that is fully analytical and predictive. The theory uses analytical equations to predict the mixing behaviour ...
Rapid channel incision of the lower Pearl River (China) since the 1990s as a consequence of sediment depletion
channel incision lower Pearl River water discharge sediment depletion
2009/5/13
This paper reported a dramatic channel incision (>10 m in the deepest cut) during the past 10 y or so in the lower Pearl River, the second largest river in terms of water discharge in China. The chan...
