Natural landscape

5 The cross sections describe the transformation process of the Dutch landscape in five phases. The natural landscape of the lowland polders would have looked much like the landscape in the previous photo.

In each of the landscapes described here, water and water levels play an important role. If natural forces of gravity no longer drain a landscape and man intervenes we refer to it as a polder landscape.
