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.

To predict the behavior of solutes and suspended particles in wetlands, it is necessary to estimate advection and
longitudinal dispersion. To better understand these processes, measurements were take...
