npub1vypq6jrs2melhg7y3ug2jn6dguqs6kzxhmtcd3a3qezelautzyvquxaghx (npub1vyp…aghx) Occasional drizzle, but not a lot.

I've pondered whether one could dam up flows by spreading sodium polyacrylate to turn rainwater into an improvised marsh. Stores 100-200kg water per $ of material. Could probably roughly harden 1kg of lava per kg water, depending on lava temp. $10k (3t) = 517m³ wall. Triangular profile = 7m tall x 150m long. Not that it'd neatly form a wall, just slow the flow, like marshes do.

I'm not sure how quickly it desiccates after rain, though.
