I've wondered about these salt evaporation ponds a lot. It's the traditional way sea salt has been harvested in Japan from the sea and also in the mountains of the Andes from mountain deposits of salt water. And it is still harvested industrially like that on some islands.

The thing I'm really curious about is this is happening on a large enough scale does it begin to affect the amount of precipitation that can occur? I'm wondering if it can be utilized to increase rainfall during times of drought

Maybe even long canals to transport the ocean water far inland in very shallow streams that are meant to be evaporated by the sun over time. This uses almost no energy on our part, produces salt, and might possibly help increase rainfall?

Salt kills most plants. Bringing it inland would basically stop agriculture for hundreds of meters surrounding the canal. If it goes into the aquifer it's even worse.

Also, inland is usually higher than sea level (where it's lower you get lakes / ponds / swamps, unless it's actively managed), so you would be creating ditches a hundred meters deep if not more.

I'm also not sure that local water would increase rainfall, any amount of wind would sweep moisture off immediately. The most it can do is to increase the humidity of the surrounding area when windless.

Remembering that water flows downhill, and places a long way inland are likely to be significantly higher than sea level, I'm not sure how feasible digging long canals many miles inland will be.

Particularly if they will then fill up with salt.
