inundation

The first season was the flooding, or inundation, when the Nile valley was essentially submerged in water for a few months or so.

So, naturally, their first calendar was divided up into three seasons, each based on the river's changes: inundation, subsidence and harvest.

The flashy brochures and pamphlets left by the sales reps are often followed up with meals at expensive restaurants, meetings in warm and sunny places, and an inundation of promotional gadgets.
