Generally when an area floods the water comes from somewhere else. Not a lot you can do to prevent that. We must remember that flooding is a naturally occurring thing and that some of the best farmland in the world exists because of that flooding. Flooding drops nutrient rich silt on the soil.

depends on where the land in question is. if there's nutrient rich silt in floodwater, some place upriver must be eroding.
if floods occur because of high groundwater, improving drainage and digging ponds won't solve the problem.
if it is a natural flood plain then it should be left to nature, that is its purpose in life.
even putting in a pond once the pond fills and rain keeps soming then the plain will flood.
for me i would never conider buying any property that is on a flood plain.

A cold-adapted breed of upland rice might be worth considering, for the time being.
While it's flooded, the field won't have any weeds besides aquatic plants, and in that niche, azolla or similar will do the rice no harm. As the field dries out, the rice will continue growing, and have a considerable head start versus any terrestrial weeds.
I might experiment with broadcasting the rice before the flooding really gets serious.
