TRIPLE WOW!
Big progress today; Streams and rivers now cut their way through the terrain better: instead of going over the fields & crops (the lines are now interacting with the terrain textures)

Even with this extra task, all of EURW compiles in 1:20h on my 3 yr old laptop; not bad
Still a few minor bugs to fix, and 2 more features to build in and we should be good to go.
What an improvement !!!!!... I think I know exactly where that shot was taken.....
May I ask if the same logic will be applied to roads, which in many cases in the old EURW do not stop at river banks, but cross directly the stream on the water?
There's also another minor problem: when river beds are quite wide they are displayed as small lakes, while they should show up as a dry beds with a small stream in the middle.
It's the case of the Po Valley above, where the Po tributary rivers, flowing from the Alps southward, have a constant volume of water and bed shape throughout the year. They only raise their level during the wet season and in the spring when snow melts. They are all fed by glaciers, which keep them going even during summer.
On the other hand, the tributary rivers flowing northward from the Appennini are almost dry during summer with a sort of medium to low stream during the other seasons, but they are subject to sudden flash floods if big rainstorms hit the mountains. The Appennini do not reach the same altitude as the Alps, so there are no glaciers to keep a constat water feed to the northward tributaries.
This is what causes large bed rivers, normally paved with stones and corrosion debris, with a relatively narrow and shallow water stream in the middle, which can extend up to the banks in very little time during flash floods, expecially in summertime. Large river beds are also man-maintained as such, as a measure to allow enough room for flash floods to expand and slow down, instead of flooding the surrounding farmland or, worse, towns and cities. In the fall of 1966 this is exactly what happened with the river Arno when it flooded Firenze, caused by a containment dam up in the mountains that collapsed under a huge flash flood.
These Appenini rivers are very dangerous and we know them very well. Many people lost their lives because they were fishing while standing on the dry bed of the river and paying no attention to the sudden thuderstorm up in the mountains. It still happens every so often. Crossing these rivers that were normally small streams while, all of a sudden, became furious walls of muddy waters and debris, caused a lot of troubles to the advancing Allies during the liberation of Italy from 1943 to 1945.
I don't know if CFS2 can be instructed to display the areas where these dry river beds expand as such. The Italian boot is all like that, except north of the Po river. Zooming in the above screenshot shows all of them as small, narrow lakes which, in reality, are not there.
If it doesn't, I guess we'll have to live with it as we did so far.
Cheers!
