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.
