    sorry if i interpolate my profil 1 with elevation point layer result is there :

    0 36.89
    1.722648 37.1
    3.417569 36.78
    3.927871 36.93
    4.346167 36.82
    4.76373 37
    6.111168 38.12

    3 points are created and only two points are ok with z, the others are false

    for example, here is my profile 1:

    0 39.3
    1.722648 37.1
    3.927871 36.93
    6.111168 39.3

    here is my profile 1 imported with rasmapper :

    0 36.93
    1.722648 39.3
    3.927871 39.3
    6.111168 37.1

    here is my profile 1 interpolated with elevation point layer :

    0 36.89
    2.375541 38.34
    2.933068 38.24
    4.698927 41.96

    x values are ok but z values are false

    Hello,
    I have an error with velocity map (other maps are OK) :

    Does anyone know what it means ?

    Regards.

    Hello,
    You must open your file projet *.r01 with steady.exe

    Hello,

    OK for downstream condition, thanks! (My interest is near the bridge, downstream condition is far enough).

    Sorry, oscillations appears with 0.5m step interpolation, under 1 m. (it’s also depending on manning value).

    In this model, measuring station is unfortunately located near the bridge on supercritical flow, that’s why i must interpolate with very low step, and i founded that oscillation problem.

    Best regards.

    Thank you Robert!

    I thought Samuel’s equation must be used in case of unsteady flow data (relation time step and xs interpolation step)?

    I choose a low xs interpolation step because of warnings in cross section Output “…this may indicate the need for additional cross sections” I thought results always where best with a low step?

    best regards.

    – step 1m in the first image
    – step 2m in the second.

    The 2 xs are located after a bridge that make flow be supercritical.

    I dont understand why xs interpolation step can be so significant
