This case study describes the flood risk management plan and the related restoration of a formerly canalized eight kilometres stretch of the Isar river in the city of Munich (the so called “Isar Plan”). Still in the beginning of the 19^th century, the Isar was a typical wild alpine river with wide gravel islands and sandbanks and a constantly changing riverbed. In the middle of the 19^th century after repeated flooding suffered by the Lehel, Au and Thal districts in Munich, hydraulic regulation began, and the riverbed was canalized.

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.

Klaipėda is a coastal city with almost all of its territory located on coastal lowland, and the Smeltalė river situated in the Southern part of the city, falling into the Curonian Lagoon within the city area. Regular floodings of the southern city areas due to flash floods in the Smeltalė River and Baltic Sea level fluctuations are the main problem of the Klaipėda city case study area.

The City of Växjö is situated in the southern part of Sweden, surrounded by forests and lakes. As many parts of the central city of Växjö were built upon wet and swampy areas they are vulnerable to floods after heavy rainfall events. One of the most affected parts is the street Linnégatan which is built on a previously existing small stream and which is situated much lower than the surrounding built areas. In past years, rainwater often flooded the street and the nearby buildings’ basements and cellars.

In 2000, the governments of Bulgaria, Romania, Ukraine and Moldova pledged to work together – with the signing of the Lower Danube Green Corridor Agreement - to establish a green corridor along the entire length of the Lower Danube River (~1,000 km). All partners recognized a need and shared responsibility to protect and manage the Lower Danube in a sustainable way.

Situated in East Anglia, Norfolk Broads (Broadland) is one of the finest areas of wetland in Britain. It includes both open water, the Broads themselves (a network of mostly navigable rivers and lakes), and the low-lying marshland surrounding the tidal reaches of the Yare, Waveney, Bure rivers and their tributaries. These rivers reach the sea at Great Yarmouth.

IRRINET is an IT irrigation system aiming to advise farmers on efficient water management. This web service was developed with public funding by the CER (Canale Emiliano Romagnolo, a water consortium located in the Emilia-Romagna region) based on a 1984 project which tested the use of telematics tools in agriculture in Emilia-Romagna. In 1999, with the arrival of Internet, IRRINET started to be developed in a web form and is still active and operative in this Italian region.

Amphibians suffer a global decline. This has made them the most threatened group of vertebrates on the planet, with more than a third of the species under some degree of threat. The main threats include the destruction of their habitat, changes in climate, emerging diseases and the disappearance of places of reproduction.

The LIFE BOSCOS Menorca project, launched in January 2009 by the Menorca Island Council, has as its central objective the adaptation of Mediterranean forest ecosystems to the adverse impacts of climate change through sustainable forest management practices. This five-year project seeks to directly address the challenges imposed by climate change on Menorca, an island that, due to its geography and climate, faces unique environmental risks that require specific adaptive solutions.

The Manzanares River, as it passes through the historic Royal Site of El Pardo, has undergone various hydromorphological alterations over the years, profoundly transformed both the riverbed and its banks. These transformations have resulted in the significant loss of fluvial space, habitats diversity, both longitudinal and transversal connectivity of the river, and public accessibility to its banks.
