The Dutch Coast |
The Dutch coast is dominated by broad sandy beaches and extensive dune ridges. The Wadden region - with its dune islands and the abundance of birds and seals - belongs to the most important nature areas in Europe. The mainland coast (provinces Noord-Holland and Zuid-Holland) contains the most important sea resorts of the country, and they are surrounded by impressive dune areas. These dunes protect the low coastal plain - with its polders and peat meadows - against the sea, since 25% of the Netherlands lies below sea level; without dikes, two-thirds of the Netherlands would be periodically flooded. The southwestern part of the country (the "Delta") has developed as complex estuary of the rivers Rhine, Meuse and Scheldt, with a wide variety of salt and brackish ecosystems. The new dikes of the Delta Plan protect the islands against the sea. Coastline length: 523 km, of which 353 km North Sea coast (incl. 254 km with dunes); the rest concerns the coast of the Wadden Sea and the Westerschelde estuary (towards Antwerp).
Nature & Landscapes
Sea
The sea is the largest nature area of the Netherlands, with many kinds of fish,
shellfish, crabs, shrimp, worms, etc. The coastal waters are important nurseries
for the whole North Sea and have the most abundant animal life. The marine ecosystems
are under severe fishing pressure; the seafloor is constantly being ploughed
and various fish species are being threatened by extinction.
North Sea:
natural habitat of about 200 fish species, including Smelt, Haddock, Plaice,
Sole, Sprat, Pollack, Herring, Mackerel, Cod and Whiting; in the open sea Harbour
Porpoise, a mammal belonging to the Dolphin family, is present. Sometimes in
autumn, Sperm Whales come from the north and get lost in the North Sea; when
they get into shallow areas they have difficulty getting back and sadly get
stranded.
Wadden Sea: part
of an international tidal area, an outstanding nursery for the North Sea. This
area hosts Harbour Seals (more than 1000), Grey Seals and numerous coastal birds,
fish and shellfish.
Voordelta:
in the shallow sea in the south-west, a tidal area with sandbanks and channels
has developed in front of the sea dikes. This Voordelta is important as a marine
nursery, as well as for seals and coastal and sea birds.
Remnants of the former Zuyder Zee after the creation of dams and polders are:
IJssel lake:
shallow, fresh inland lake of great importance for water birds and for water
management.
Marker lake:
shallow, fresh water lake, important for water birds e.g. diving ducks and swans.
The dike Enhuizen-Lelystad was the start of a land reclamation project; due
to the importance of the area for water birds and especially the Smew, the reclamation
has not been realised.
Estuaries
In the southwestern part of the country most estuaries have been turned into
coastal lakes by the Delta dams; the largest lakes are:
Haringvliet:
now a large fresh water lake; on the island, Tiengemeten a nature restoration
project has started in the 1990-ies;
Grevelingen:
now a salt water lake with some sandy islands
The following areas deserve special attention:
Biesbosch: a
former freshwater tidal area, now almost without tides due to the Delta dams.
Oosterschelde:
this estuary has partly kept its tidal character after the creation of the famous
storm surge barrier, but the natural values have decreased considerably. National
Park (in formation).
Westerschelde:
the last natural estuary, a funnel-shaped tidal outlet, of which the inland
part gradually changes into the river mouth of the Scheldt.
Salt marshes
and mud flats
Along the edges of the Wadden Sea and the estuaries mud and sand flats occur;
the higher ones (only flooded at very high tides) are covered with halophytic
vegetation; daily high tide does however fill the channels, which keep shifting
their position.
Dune landscape
Younger Dunes occur along almost the whole North Sea coastline, with total surface
area of 40 000 hectares. Some examples:
Schiermonnikoog: National
Park (in formation)
Dunes of Ameland
Dunes of Terschelling
Dunes of Vlieland
Dunes of Texel: National
Park (in formation)
North Holland Dune Reserve
Zuid-Kennemerland:
National Park
Amsterdamse
Waterleidingduinen
Meijendel
Older dune forests
Only the forests in the sand barrier region between Haarlem and The Hague resemble
the once forested sand barriers and Older Dunes.
Cultural landscapes
Behind the dunes is a varied collection of cultural landscapes: peat meadows,
polders and reclaimed marshlands with many ditches and traditional windmills;
The Bulb district between
Haarlem and Leiden; the greenhouse area of the Westland (south to Den Haag).
The Delta area offers some spectacular achievements of civil engineering: the
harbour of Rotterdam (the largest in the world) and the Delta Plan with its
dams and bridges which connect islands and at the same time have to guarantee
the safety of those islands.
Nature management
Despite the high population density, the Dutch coastal zone still has a lot
to offer in terms of nature and nature oriented recreation. For a major part
this is due to continuous efforts of non-governmental organisations, some of
which are collaborating under the name "Kust en Zee", at the initiative of EUCC
- The Coastal Union; since 1977 Stichting Duinbehoud has played a pioneer role
for dune conservation. Fortunately, the conservation of the coastal landscape
now has a high priority in the Dutch government's nature policy. Natural values
now play an important role in the overall policy for the coastal zone, e.g.
concerning coastal defence.
Visitor centres
The most important centre for the Wadden and the North Sea is:
EcoMare:
visitor centre with a seal sanctuary; member of "Kust & Zee". Internet: www.ecomare.nl.
In the dune area there is a considerable number of visitor
centres; see also the various regional pages.
History
Origin.
Hundreds of millions of years ago, the country was part of a shallow coastal
sea. During the various Ice Ages, the southern North Sea area dried up. At the
end of the Riss Glacial (200-125 000 years ago), the glaciers deposited lateral
moraines: the Veluwe, Utrechtse Heuvelrug, Urk, Friesian cliff coast, Wieringen
and Texel. After a period of flooding, the southern North Sea area dried up
again during the next and last Ice Age (Würm Glacial, 70-10 000 years ago) and
was completely covered by wind-borne sand deposits. Under the influence of the
rising sea level, these sand deposits formed salt marshes and sand barriers
about 10 km west of the current coastline. In those days, most of the country
was a huge Wadden area. After a period of further sea level rise, the sand barriers
moved towards the continent until they arrived more or less at their current
position, ca. 5000 years ago. Low dunes developed on these sand barriers, the
so-called Older Dunes; this process lasted to about the Roman era. Large peat
moors developed in the Wadden landscape behind the sand barriers. These peat
moors were often flooded and covered by sea clay. Due to differences in the
supply of sand, the size of the sand barriers and the location of the large
rivers, three completely different types of coast have formed between 3000 and
1000 years ago: the Wadden coast, the closed dune coast (coast of Noord-Holland
and Zuid-Holland) and the estuarine coast (the Delta).
Wadden coast. The relatively low sand barriers in the Wadden area were
interrupted by large tidal inlets, namely Zijpe (at first near Bergen, later
more north above Camperduin), Vlie (between Vlieland and Terschelling) and the
Eems estuary. Because these tidal inlets caused a continuous inflow of salt
water in the northern area, this remained a wadden area, a shallow basin with
tidal areas, sand banks, salt marshes and channels and a relatively small tidal
difference (2-3 m). It was a relatively calm environment in which tiny particles,
consisting of young sea clay from the southern North Sea, were deposited. The
Wadden area included Lauwerszee (between Groningen and Friesland), Middelzee
(right through current Friesland) and Vlie. In the 11th century, the Vlie expanded
at the expense of Almere, a number of large peat swamps southeast of Enkhuizen:
this is where the Zuyder Zee came into being, which would then become a lot
larger, partially due to a large number of storms in the 13th century, which
also caused the Dollard to come into existence. The sand barriers were swallowed
by the sea and provided sand for a series of young Wadden isles. Due to the
storm tide on All Saints' Day in 1570, the island Texel was permanently divided
from Huisduinen (Den Helder) by the Marsdiep channel.
Coast of Holland. Between the Wadden coast and the estuary of the Meuse,
the relatively broad belt of sand barriers was only interrupted by the old Rhine
estuary near Leiden. Behind the beach barrier an enormous lagoon developed with
fresh water. In this area new peat developed on top of the sea clay: the Holland
peat. Small rivers and brooks crossed this vast area. The western parts of the
sand barriers were washed away in the 11th and 12th century, a part was covered
by Younger Dunes (1000-1600), and the rest of the area was cultivated: the "geestgronden"
(sandy soils between the dunes and the polders, now the bulb fields).
Delta area. In the south west, the sand barriers have always been interrupted
by a series of estuaries: tidal outlets connected with the deep, funnel-shaped
river mouths of the lower Rhine (Lek and Waal), the Meuse and the Scheldt. The
relatively large tidal differences (3-6 m) have profoundly influenced this area,
with channels up to 40 m deep. This caused a group of islands to form, with
dunes on the most western tips. High tides and storms resulted in sea clay depositions,
partially on the old sea clay (salt marshes and mud flats) and partially on
the remnants of the peat area.
Occupation and reclamation. After the last Ice Age, 4500 years ago (Stone
Age), inhabitants appeared in the coastal zone again, and after that many cultures
left their traces: the Vlaardingen culture, Celts, Friesians and other German
tribes and - after ca. 50 B.C. - the Romans. After the collapse of the Roman
Empire (shortly after 400 AD) the whole coastal region was conquered by the
Friesians; a population increase led to the cultivation of the sand barriers.
In the 6th, 7th and 8th century the climate was calm, so peat growth was fast
and the ground level rose. Inhabitants of the peat and clay area built terps.
Canals were dug to remove water from the peat areas and the beach plains located
between sand barriers. In the dry period around 900 AD, large peat areas were
reclaimed. However, Vikings raided the coastal area and the locals built strongholds
to protect themselves against these plunderers. These strongholds can still
be recognised by the name "burg", like Den Burg (Texel) and Middelburg (Zeeland).
The climate in the 10th and 11th century was more stormy and the sand barriers
often broke, which caused peat areas and islands to be partially swallowed by
the sea. It became necessary to build dikes around the land; which was done
on a much larger scale since the 11th century. Monastic communities took the
lead. With these dikes (made of a combination of clay, turf, seaweed and wood)
the first polders came into being, which were drained by sluices, which were
opened at low tide. At first the building of dikes had a defensive nature, but
in the 12th century it was more often aimed at land reclamation.
A gradually increasing activity in the peat areas, inside and outside the dikes,
was selling peat soil and cutting turf. Peat was collected at all possible places.
After peat was being collected beneath the water table, large lakes developed
in the peatlands by storms.
Political development. Proceeding from the Frankish kingdom after 800
AD, a number of relatively independent countries developed: counties, dukedoms
and the diocese of Utrecht. After the splitting up of the Frankish kingdom,
the current Dutch provinces belonged to the German Empire, while the current
Belgian provinces were lieges to the French king. During the 15th century various
counties became united again under the dukes of Burgundy, who convened all the
states in 1463: the first "States General". The name "the Netherlands" dates
from this time because they were near ("neder") the administrative centre Brussels.
Partially inspired by the Reformation, Prince William of Orange started an independence
war in 1568 against the kings, which had moved to Spain: the "Eighty Years'
War". Around 1600 this led to the separation of the Northern Netherlands and
the establishment of the Republic of the Seven United Provinces. During the
17th century ("The Golden Age") the Republic became an economic super power
thanks to international trade and shipping and due to large-scale collection
of turf in the peat areas. After the French occupation and the defeat of Napoleon
near Waterloo (1815), the Netherlands, Belgium and Luxembourg became united
under King William I, until Belgium separated itself in 1830.
Large scale developments. The prosperity and the associated need for
space gave strong impulses for the battle against the ever-growing lakes in
the peat areas; the peat washed away up to the old sea clay layer and during
storms farmlands and even cities became threatened. Some disastrous storms (e.g.
the storm tide on All Saints' Day in 1570), the rising sea level and the collapse
of many peat areas made the government decide to reclaim many lakes and small
inland seas in the 17th and 18th century, with the help of numerous windmills,
starting in Noord-Holland. One of the last is the series was the huge Haarlemmermeer
(18 000 ha) between Haarlem and Leiden, in 1852. In the 19th century followed
large scale building projects to level the Older as well as some of the Younger
Dunes between Den Haag and Haarlem; these flat sandy soils ("geestgronden")
became to be used for the cultivation of flower bulbs.
The shipping, which was so prosperous during the 17th century, did not survive
the protectionist policies of England (Cromwell) and France and the resulting
military conflicts in the 18th century. Not until the second half of the 19th
century did the Rotterdam harbour get an unprecedented economical upsurge that
made it Holland's first harbour and a little later the largest harbour in the
world.
Plans to tame the Zuyder Zee were realised by building the IJsselmeer Dam (Afsluitdijk)
in 1932. This dike caused large changes in the Wadden Sea and also caused erosion
in the northern part of the dune coast of North Holland. Gradually the IJsselmeer
changed from saltwater into freshwater and was made smaller by the creation
of a series of polders.
The storm tide in 1953 resulted in the realization of the so-called Delta Plan,
which provided the building of a series of connecting dams between the islands
in the Delta Area.
