DIEX-Flow ver.1.0 was only applicable to surface velocity data.
Now, in order to expand the scope and application, DIEX-Flow ver.2.0 supports all point & line velocity data at everywhere.
By energetic development, various types of velocimeter has been put into practical use.
Because the study of velocity inter/extrapolation is quite rare, there is not new technique.
Point or Line velocity measured by velocimeter is interpolated and extrapolated over across-section with the proper physical background by using DIEX (Dynamic Interpolation and Extrapolation) method.
According to the precise verification using ADCP, evaluation error of discharge is less than 5% on average.
DIEX method, which interpolate and extrapolate the velocity based on the dynamics balance in the cross-section, can calculate discharge with high accuracy even if the missing occurrs, or river bed shape is complicated.
DIEX-Flow does not matter the type of velocimeter.
Reference
DIEX-Flow support you to create input files.
Input data will be visualized, and it is easy to confirm the observation data & setting status.
Start calculation for velocity inter/extrapolation and discharge.
DIEX-Flow visualize automatically
- Cross-sectional velocity distribution
- Lateral profile of depth-averaged velocity
- Time series of discharge
