I have found out the likely reason that tactile paving markers on dual-use paths are the wrong way round!

A page on the UX StackExchange discusses tactile paving on dual-use paths and the best explanation is that it can be uncomfortable to walk on longitudinal ridges, whereas transverse ones are OK.

(Apparently the usual terms are "tram" vs "ladder".)

I occasionally get a painful twinge in my ankle when I tread on the edge of a badly laid paving stone, so I can sympathise. But surely tactile paving is supposed to be felt by the feet, so it should not hurt people who tread on it even inadvertently!

Ah from https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/289245/tactile-paving-surfaces.pdf (dated 1998)

"On the cyclist side, the surface should be laid with the bars
running in the direction of travel (Figure 29 page 75).
This arrangement was chosen because it was felt the rumble
effect created by the transverse pattern would deter cyclists from
entering on the pedestrian side. "

Ironically, experts say the summer storms have produced 'the wrong kind of rain': intense downpours that run off the rock-hard ground, as opposed to soaking down in the underground acquifers which give most individuals drinking supplies. 'When the bottom is baked, it really runs off,' explains Morley. 'You need very long periods of rain to obtain the ground soft, then it actually starts to absorb water.' ,water systems (http://watersinfo.org/house/drinking_dater_filter) house water filter (http://watersinfo.org/ind/commercial_water_purifiers)
