All measurements are outright guesses. Others smarter than me will be able to guess better than me.

The idea is to dig trenches, maybe a foot wide and 10 feet deep. The ditches would be about 15, maybe 20 feet apart. I guess they would need some kind of grid cover for safety.

However, first, rocks, and or pebbles would be used to fill the trench. Pumps would be installed at the end of each trench. During flooding, the flood water could go into the trenches. During dry spells, the water could be pumped out of the trenches and over the crops.

If the flooding cannot be handled by trenches, the water could be pumped into tanks and used later.

I mean, why let the flood water ruin the crop? Why not save the flood water for later when it’s needed. Perhaps, instead of a tank, a pond could be used.

As I said, just a crazy idea. Just saying, if it just works once or twice; if if saves one or two crops…. Then what do I know. Twice I tried to grow tomatoes. As I say, I tried.
