For the Instructor
These student materials complement the Coastal Processes, Hazards and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

The terp mounds were a very resilient system against flood protection. However, the size of the constructed mounds was limited and they could only support small villages. With continued population growth and the need for more protected space in villages, the Dutch began building ring dikes around towns. As settlements continued to expand into the low, coastal areas, the land was drained using increasingly elaborate means (diteches, windmills, steam pumps). This drainage, coupled with peat harvesting and poldering (a method used to reclaim land from the sea), caused extensive subsidence, which increased flooding vulnerability. The increasing populations and value of property inhabiting lowlands required higher and stronger dikes, so much so that now most of the Dutch population and economic activity is supported by areas below sea level that are protected from floods by massive, nearly-indestructible dikes and surge barriers. With such high consequences of flooding, dikes and barrier structures for much of the country are designed to protect against a flood with a 1 in 10,000 year recurrence interval.
