appearance of water

[Kenyeri]

Hello! I have a problem that if I change the level of the ground surface, water appears, which I have also noticed, car traffic does not work, changing the region grid region starts traffic but water appears. The last build in which this does not appear is 123801, and the following ones are included. What can be the solution to this?
Thank you in advance for your help.

I change the level of the ground surface, water appears,

The water you are seeing is the Water Effect Layer which covers the entire route at just below 0m. If you lower the ground surface below 0m it will appear. This layer can be raised to any height when required to show the water (e.g. a dam, river, pond, harbour, etc) where it is needed and lowered to any height to hide the water (dry land) where it is not needed.

It is easy to fix, just delete the Water Effect Layer and add a new one (if you want one) at a lower height.

• In Surveyor 2.0 open the Layers Palette, right click on the Water Layer and select the Delete option. See the forum thread https://forums.auran.com/threads/working-with-water-height.180961/ for more details about the Water Effect Layer in Surveyor 2.0.
• In Surveyor Classic select the Edit Effect Layers from the Display menu then select the Water Layer and hit the small red x button on the right.

When developing a route I delete the default Water Effect Layer and only recreate it (or them - you can have more than one Water Effect Layer each with different coloured water and surface effects) after all the terrain work has been completed.

Thank you for this advice Peter, but may I please run a possibly more complex issue past you.

Am running TR22PE, Build 132285. Have a 50 mile TransDEM derived WIP of the GWR Carmarthen to Aberystwyth line and am using Surveyor Classic set at 5mm grid. The sea/tide/shoreline is represented at each end of the route and is set at a height of 2.8 metres. All waterways above that height have been created using the River Spline Muddy Water PBR asset.

OK, two gremlins have surfaced. I was adjusting track heights at a point some 12-15 miles inland to create a more level surface for the site of Pencader Station. The TransDEM determined elevation for the track was originally 129.38 metres but I reset the track height cursor down
to 119.00 metres and then hit the level track button. The depression formed by this action while showing the stretch of track at its new adjusted height was now also full of water as per the Water Effect layer, possibly at an elevation height of about 120/121 metres. Examination of the larger site area using the Show Wireframe facility revealed a lake extending out over an area roughly 25 x 4 grid squares. Further examination of adjoining areas revealed a second, similar, water effect contamination roughly the same total area but set at an angle following the contours of a track embankment.

I've no idea how I managed to create these two inland water effects, one at a height of 120 metres and the other on a slope ranging in height from 140 upto 175 metres, particularly when I'd already created a portion of the Bristol Channel and the Irish Sea, both at 2.8 metres. Nevertheless, I've clearly hit the wrong button with the parameters set at the wrong settings at some point in time. As I don't appear able to erase the two gremlins by any common method and am trying to avoid making more mistakes, can you (or anybody) please point me toward a solution.

Many thanks

I have never used TransDEM so I do not know if it comes with any water effects or water layers.

Your statement that one water effect has a slope on it indicates to me that it is a water effect layer (you can add a slope to them, probably for water skiing ).

I'd already created a portion of the Bristol Channel and the Irish Sea, both at 2.8 metres.

That confuses me a bit. By "both" do you mean that you have created two water effect layers, one for the Bristol Channel and the other for the Irish Sea? If so then from my experiences with water effect layers you only need one layer. A water effect layer will automatically cover the entire route at the set height. You can then adjust that height up or down or even give it a slope in different areas using the brush tool. So the one water effect layer can be used to create rivers, lakes, ponds, farm dams, oceans, etc all at different heights (and slopes) if needed in different locations.

The only time I add a second water effect layer is when I want the new water surface to have a different appearance (e.g. different colour and/or surface effects such as roughness, etc) from the first water surface.

So is it possible that the mysterious "lakes" you have at different heights are from the same water effect layer(s) that you have added for the Bristol Channel and/or Irish Sea?

Because they are easy to create one simple test would be to save your route (to create a backup if something goes wrong) then delete your Bristol Channel/Irish Sea water effect layer(s) to see if that removes the "lakes". If it does then simply add a new single water effect layer at 2.8 metres for both the Bristol Channel and the Irish Sea.

As to how this can happen? Is it possible that you had, at some point, selected the water effect layer instead of the ground layer when you were terraforming the landscape and this altered the water height in those areas? There are other possibilities and I have encountered a similar issue when working on a very large route - it was easily fixed with the layer Delete button.
