Searching for the Sources of Ouse Dyke #5

alexkemp 于 2017年四月17日 以 English 发布 最后一次更新于2022年七月 4日。

(my problem is not in starting, it is in stopping)

  1. Begin
  2. Desk survey
  3. Sources found to Lambley Lane
  4. Culvert + stream traced to Willow Park
  • Q: When is a stream not a stream
  • A1: When it is dry
  • A2: When it goes underground

I got to Willow Farm Primary School & it should have been closed due to Easter, but the school gates were open. My good fortune, because the School Caretaker lives in the bungalow near the entrance & came to check me out. After a little conversation he took me to see the stream that ran alongside the school, travels in a culvert beneath the abandoned high-level mineral railway then empties into Ouse Dyke.

This is the stream on the other side of the metal fence but look carefully - there was no water in the stream when I took this photo:–

unnamed WFPS stream

And here is the culvert (middle of picture) that runs beneath the railway line:–

Update 4 July 2022

Mapillary has changed it’s download URLs & therefore all links within my diaries that used photos stored in Mapillary in the old format are broken. I’m slowly going through to update them. The new URLs are terrifyingly long, but show OK on my screen (and I hope also on yours).

Many streams and rivers in desert areas are dry most of the time. Use the tag ‘intermittent=yes’ and/or seasonal=winter, summer, spring, autumn? One such river has an annual regatta … the regatta was called off one year because there was water in the river. https://en.wikipedia.org/wiki/Henley-on-Todd_Regatta

Streams that go underground … layer=-1?

Hi @Warin61

I’ve added intermittent=yes as that was my experience on the day.

As it happens the culvert as mapped does have layer=-1 just like a ‘normal’ culvert. In fact, in this case the overhead railway is layer=1 & the culvert as built is layer=0, but in the same way as OSM does not render that situation correctly for the meeting of road & rail, I’m quite sure that the culvert would appear wrong, and thus has been ‘wrongly’ mapped (in my experience road bridging over rail gets mapped accurately, but rail bridging over road does not).
