The 19^th century industrialisation in Lodz heavily affected the city’s rivers, altering their ecosystems and hydrology. Many rivers in the densely built-up city were canalized. This resulted in a higher flood risk from runoff during heavy rain periods. Low water retention also implies reduction of soil moisture during dry spells, contributing to higher temperature and reduced air humidity (urban heat island). Based on climate change projections, it is expected that the intensity of heavy rain periods and higher temperatures will increase and exacerbate these problems.

A series of actions were taken to address erosion in the coastal area of Marche region in Italy. The interventions carried out in the section of coast between the municipalities of Sirolo and Numana represent an example of what has been implemented throughout the whole coast of the region. Interventions included: beach nourishment, cliff stabilisation and removal of a portion of artificial reef.

The Kruibeke Bazel Rupelmonde (KBR) Controlled Flood Area (CFA) is a key component of the Belgian Sigma Plan for the Scheldt Estuary. The Sigma Plan is an integrated flood protection plan that combines dikes, seawalls and flood areas to protect approximately 20,000 hectares of land from flooding.

Climate change impact assessment has been an integrated part of the design and planning of the Copenhagen metro since the first metro line was designed in the mid-1990s. For this scope, Metroselskabet, the Copenhagen metro company, developed a climate change adaptation strategy, which supports the integration of adaptation aspects since the planning and dimensioning phase of the metro system. Apart from the first metro line, opened in 2002, and related extensions in following years, in 2019 Metroselskabet put into operation a new city circle line (Cityringen line M3/M4).

At Nijmegen, the Waal River bends sharply and narrows. This creates a bottleneck, which often caused flooding of the historic city centre of Nijmegen, located on the south bank of the Wall. After the floods of 1993 and 1995 and faced with increased risk of flooding due to climate change, the city of Nijmegen decided to give more room to the Waal River, at the same time protecting nearby natural habitats and providing recreational space.

The Flemish coast is intensively used by many actors, embracing coastal towns, commercial ports connected to industrial areas, leisure marinas and touristic activities. It is exposed to flooding due to storm events and sea level rise. In 2007, the Flemish Government, after a safety test revealing an insufficient protection of the coast, started the elaboration of an Integrated Master Plan for Coastal Safety that was finally approved in June 2011.

The Sigma Plan is an integrated flood protection plan that was firstly established in 1977, in reaction to a major storm surge flood in 1976. The Sigma Plan offers protection against storm surges as well as river floods caused by excessive rainfall. Its objectives also include nature protection.

The rural district of Aurich in Lower Saxony is the northernmost district of Germany, bordering the Netherlands and the North Sea. Its natural environment is characterised by the Wadden Sea, by three islands off the coast and by more than 70km of coastline. Dominant habitats include coastal wetlands and inland moors and swamps. Large areas of the Aurich District are protected, the Wadden Sea National Park of Lower Saxony being only one example. In addition, large areas lie below sea level, both on the islands as well as a strip 2 and 15 km wide behind the mainland coast.

Hesketh Out Marsh is the biggest managed realignment project in the UK, and is one of the country’s most important estuary habitats for birdlife. The original saltmarsh was isolated from the estuary in 1980 by the creation of an outer wall, and was used for growing crops. With the sea level rising, it was necessary to create stronger sea defences. By a process known as “managed realignment”, seawater has been let back in to flood the land, re-creating saltmarsh and providing space for nature.

Over a century ago a sparsely populated landscape of water meadows was transformed into an industrial conurbation, and the untamed river Emscher, in the Ruhr area, turned into a man-made system of open waste waterways. Due to subsidence caused by mining, it was impossible to build an underground sewer system. Therefore, the Emscher and its tributaries were regulated and used to transport the wastewater together with rainwater on the surface. This made the Emscher simply a great open wastewater channel.
