From the post:
In the Netherlands, a complex system of dikes, canals, dams, and delta works provide much needed flood protection in a country where half of the land is less than a meter above sea level. These marvels of modern engineering actually shorten the Dutch coastline and, in places, create freshwater lakes out of what were once salt water inlets of the North Sea.
Constructing a system as large and complex as this requires a team of individuals with specialized skills. You need engineers to make plans, craftsmen and workers to build and operate the dikes and pumps, and managers to coordinate your efforts. In Pandemic: Rising Tide, you become a member of one such team, striving to modernize the Netherlands’ flood control systems. Like other games in the Pandemic series, you’ll take on a specific role and must use your special abilities to improve your team’s chances.
