I am looking at a close area near my home, which shows an unmarked areas round a small beck/river, can anyone please explain what these lines refer to, I am guessing at two options,1) contour lines, but not showing height above sea levels, or 2) a marked flood plain area, as they are shown all along the Beck / River until it reaches a major river source.

Enclosed an section in question taken from Drone Scene chart
The query is the continous dark line encompasing the Blue beck
As above, they are contours - every 10m.
Only every fifth has the value on it … so at 50m intervals.
Your area is pretty flat - so you might have to search a bit to determine the value of each of the ones between annotated contours.
In Drone Scene there’s also an “Elevation Tool”
If you click on that and then a location (or contour) it will tell you the height.
Clicking on the red dot (that I added) in your area gives a value of 20m (top left).
Also, in Drone Scene, there’s a location share button …
Using this, and pasting the link here, helps someone else know where your are referring to. “near my home” is less informative. 
A link example to the location you are referring to …

Thanks very much for the explanation, it was the lack of numbers showing heights that threw me, will look again in more details, thanks again
