Shortening the coastline where technically possible
Numerous dyke plans developed by the Zuiderzee Vereeniging preceded this design by Cornelis Lely et al. After this plan many more appeared before construction started. Lely was not only an inspired engineer, he was also a shrewd politician. During World War I, he was Minister of Water Management, and from that position he manoeuvred the Zuiderzee plans through parliament. The 1916 flood disaster had made the need for intervention crystal clear, and despite great shortages, the plan for the Afsluitdijk was agreed to in 1918. In 1891, coastline shortening was already at the heart of the plan, only at that time it was entirely impracticable from a technical point of view. Realised in 1932, the Afsluitdijk remains a truly stunning feat of engineering. The plan was implemented more or less as envisioned in 1891. Owing to fierce resistance from the environmental movement, reclamation of the Markermeer was prevented. Safety is a common argument for reducing nature. Not much is left of that nature and today half a million people live there.

The Rhine River basin This elevation map of the Rhine River basin still shows national boundaries, but from a water management perspective, we need to look at the entire river basin. The Netherlands is heavily dependent on Rhine water, when it comes to quantity as well as quality. The melting of Swiss glaciers affects the…

Melting roof of Europe Many of the extensive glaciers depicted on this late 19th-century Alpine map, represented by the blue fields, have disappeared altogether, as evidenced by the Zapport Glacier (2b). During a dry summer, 20% of the Rhine’s flow comes from glacier meltwater, but what will happen in the future as glaciers continue to…
3. Cours du Rhin
‘Modernisation’ of the natural Rhine Before modern times, the length of the Rhine is about twice as long as a straight line from city to city: the river meanders considerably and flows slowly. As a result, it offers a great deal of storage capacity, especially with so many spacious floodplains and dykes far away from…
4. Belagerung von Strassburg
Water as an ineffective means of defence In the Franco-German War of 1870-1871, Strasbourg, one of France’s most modern fortresses, was besieged by troops from Baden and Württemberg. The extensive damage was attributed to the artillery shelling employed during the siege. This highlighted the vulnerability of traditional, static fortifications in the face of a highly…

The Rhine as a modern transportation route This atlas served as a navigational tool for ships in a time predating the advent of radar and GPS technology. Over the course of a century, the Rhine River underwent modifications to accommodate modern navigation requirements. It wasn’t until the salt discharges from Alsace, which continued until 1998,…
6. The Duitschen Rijn
The power of the swelling Rhine During periods of high water levels in the Rhine, the river valley experiences inundation. This flooding highlights the size of the valley, despite the protective dikes built along it for centuries. The changing climate and the loss of upstream catchment basins cause larger volumes of water to occasionally flow…

Room for the river, everyone wins In 1995, 250,000 people had to be evacuated from the Betuwe region due to the precarious state of the dikes. This event led to a shift in approach: The “Room for the River” initiative is a billion-dollar investment program with the aim of creating additional space for the Rhine…

Normalisation and regulation of the Rhine From 1765, the Rhineland surveyor and cartographer Melchior Bolstra initiated a systematic mapping of the Rhine. The river is measured in a standardised way and the symbolism on maps is normalised. This standardisation made far-reaching plans for regulation possible. The river is measured using standardised techniques, and the map…
9. The New Waterway
Rotterdam’s new oesophagus In the 19th century, the port of Rotterdam faced an increasing problem regarding accessibility as ships increased in size. Engineer Pieter Caland develops an audacious plan: create the shortest possible connection through the Hook of Holland and construct a dam at the confluence of the Old and New Maas rivers. The natural…

Endangered drinking water as a public good The Netherlands currently has ten public drinking water companies serving the entire country. In 1940 those companies numbered in the hundreds. In many municipalities there were only private wells, while the various sources of drinking water in a previous era were striking: Dune water, surface water around Rotterdam,…

Netherlands: terminus of river systems A fresh view on our nation is essential: viewing the Netherlands as the terminus of river systems.

17. Soil Drought
Water scarcity as a new problem In the near future, climate change is amplifying the intensity of extreme weather events. Despite a 10 to 15% increase in precipitation since the 1960s, we are experiencing drier springs and summers. This shift has consequences, illustrated by this interactive map: by the end of September 2020, large regions…
18a,b. Freshwater supply
We do not accept drought and salinization During long dry periods, the western part of the Netherlands increasingly experiences problems. As a result of the deepening of the Nieuwe Waterweg – Nieuwe Maas river, saltwater penetrates to the inlet pumping station near Gouda during low Rhine discharge. In increasingly hot summers, the water evaporates faster…
19. Heat Gradient
Weather is unpredictable, but climate typically appears more stable. Climate change historically involves slow shifts, from ice ages to warmer eras. The extensive use of fossil fuels has disrupted this natural progression. Since the industrial revolution, the climate’s behavior has shifted from occasional local heatwaves to a global trend of warming. The text on the…
