A person who travels or works along dikes, or historically, a casual laborer who hops from one dike-building job to another.
Compound word: 'dike' (embankment) plus 'hopper' (one who hops, from 'hop' meaning to jump or move quickly). This combines Dutch infrastructure terminology with English occupational naming conventions.
In medieval Low Countries, dyke-hoppers were seasonal migrant workers who literally moved from one embankment project to another, making them among history's first contract workers. Their seasonal movement across water-logged landscapes was as essential to survival as the dikes themselves!
