.
Why are polders so important?
They built dykes,
dug canals and began draining the waterlogged areas
. By the 15th century, the now-iconic windmills were built to help drive water pumps, making polder-draining much more efficient and reclaiming larger swamps and lakes possible.

at risk from flooding at all times
, and care must be taken to protect the surrounding dikes.
How do polders affect the environment?
Numerous shallow, salt or freshwater lakes were pumped dry, changing the lakes into polders
. These persistent pumping activities have caused substantial land subsidence in the areas surrounding these polders.
Why did the Dutch build dikes?
The farming opportunities began to appeal to the Dutch who dug up marshes to create farmland. … But as the marshes were drained, the groundwater was lowered and the land began to sink. It therefore became imperative to build a series of linked major
dikes to protect the land from flooding
.
Why were windmills important to the Netherlands?
Historically, windmills in Holland served many purposes. The most important probably was
pumping water out of the lowlands and back into the rivers beyond the dikes so that the land could be farmed
. In the fourteenth century, hollow-post mills were used to drive scoop wheels to drain the wetlands.
How do the Dutch dikes work?
River dikes
prevent flooding from water flowing into the country by the major rivers Rhine and Meuse

the Dutch have built dikes

What did the Dutch built to hold back the sea?
In their most ambitious project, the Dutch built three giant sea walls, called
storm surge barriers
, to protect the fragile inlets and dikes. The barriers remain open in normal weather — but during a storm surge 63 hydraulic-powered sluice gates, each 20 feet tall, keep the rising waters out.
Why is most of Australia unsuitable for agriculture?
