Snow campus III:Wonders of Winter...

After last post Wonders of Winters here another snow campus related phenomenon:

To repeat once more :) For a summer hydrologist winter is the "boring" time. Depending on the catchment location precipitation is solid and the catchment is in deep winter sleep without any reaction with only some liters of base flow. zzzz zzzz zzz 

Warm inside with a warm cup of coffee and x-mas sweets its nice to work on last seasons field data and see what happened. While working and thinking some times the falling snow flakes divert the attention and makes one wonder. Not only the light isotopic values of precipitation but even more: the self organizing abilities of water and the human factor. So looking outside the office window one sees ...   
... the world covered nicely under a layer of fluffy white stuff. All the world? No, all beside where human structures like sewer pipes. They releasing enough energy to melt the snow. Nicely seen in the picture below. Arrows in orange  are potholes and the green line with blue arrow is the sewer-pipe ~ 50cm below the grass. 

Picture showing the snow free area where a sewer pipe is.
