Hello everyone!
As the use of non-contact flow measurement methods and satellite EO methods for river flow is expanding, the need to have river cross-sectional information available is also increasing…
So, does your, (or any other) agency (or projects) store ADCP transects in a form that they might be made available for use with non-contact methods? Alternatively, does your country or agency have a programme of mapping river bathymetry…?
@Daniel Wennerberg, do I remember something in Sweden?
I can say that in the UK, the Environment Agency has done a limited amount of bathymetry mapping, which combined with their complete coverage with aerial LiDAR (although only at 1 metre resolution) has enabled me to calculate discharge from a drone video. If you are interested to see the data access site, click this link.

If you draw a box round the Thames close to where the attached image shows (just west of London), you will find multibeam bathy in addition to the now nationwide LiDAR coverage.
Doesn’t matter if your sensor is a radar or a camera, on a bridge, a drone or a satellite, you need the cross-section…!
In addition to obvious interest as a river flow measurement nerd, I’m involved a project identifying in-situ data requirements and resources for Copernicus satellite missions.
I’m grateful for any thoughts you have….
And thanks to Kristoffer for telling me – in no uncertain terms!! – to move my email conversation to this forum!
Tell me things – help advance our science!
