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...
A Method for Quantifying Stream Network Topology over Large Geographic Extents
stream network topology upstream cell count landscape ecology digital elevation models
2015/8/14
An understanding of stream network topology is necessary for a landscape-level perspective of stream hydrology and ecology. We present a method for quantifying stream network topology that overcomes c...
RELATIONSHIP BETWEEN STREAM WATER TEMPERATURE AND AMBIENT AIR TEMPERATURE
RELATIONSHIP STREAM WATER TEMPERATURE AMBIENT AIR TEMPERATURE
2009/10/29
The water temperature of streams and rivers is required for various
practical purposes and is frequently obtained by calculating the heat
budget. This method is tedious and yields rather inaccurate ...
SNOWMELT-RUNOFF MODEL FOR STREAM FLOW FORECASTS
SNOWMELT-RUNOFF MODEL STREAM FLOW FORECASTS
2009/10/29
Following the development of rainfall-runoff models the attention of the
international hydrologic program is now increasingly focused on the snowmelt-
runoff. The present simple model is based on ta...
Longitudinal Dispersion in a Stream Calculated by One Dimensional Numerical Model
Longitudinal Dispersion Dimensional Numerical Model
2009/10/28
A one-dimensional numerical model was used to simulate water stage and
dispersion of matter in a stream. The calculated results show quite good
agreement with field measurements.
Studies concerning...
Application of integral pumping tests to investigate the influence of a losing stream on groundwater quality
integral pumping tests groundwater quality losing stream
2009/10/10
Losing streams that are influenced by wastewater treatment plant effluents and combined sewer overflows (CSOs) can be a source of groundwater contamination. Released micropollutants such as pharmaceu...
