Compute 2D plots (cross section.)
•Rearrange data and add reference velocity
•Grid meshing and interpolatation
•Compute volume (measured to reference level)
Compute 3D plots (over the whole channel.)
•Rearrange data and add reference velocity

•Compute volume (measured to reference level)
Plot and save
•velocity vectors in the cross section (quiver)
•velocity vectors in the cross section with additional points
•tangential velocities over the cross section (isolines)
Plot and save
