That's how water meadows used to work,it wasn't to make the grass grow
like rice in paddy fields. A thin layer of water was trickled over the
meadows by the "Drowners" and this warmed the ground enough to make
the grass grow earlier in the season .

Oh!

Not entirely sure I agree with that. Long before my time but, the
ancient water bailiff who taught me to shoot, showed me where the
temporary dams were located to flood our meadows. The river side
grassland here is not dead flat so a considerable depth was needed to
cover all.

I understand mist irrigation can be used to protect fruit blossom from
frost.... something like providing a source of energy to supply the
latent heat of melting ice rather than it being drawn from the blossom
itself.
