Room for the River Regge, Netherlands - restoring the river dynamics

Historically, the Regge was a free-flowing shallow lowland river which meandered through a landscape containing marshes, wet meadows and sandy levees. To facilitate shipping, from 1848 onwards the river was straightened by cutting off meanders, and the river channel was deepened and widened. Dams were built to better regulate the river flow, and the floodplain was embanked to protect the adjacent land from flooding. In 1935, the river was almost completely canalised, reducing its length from roughly 70 km to 50 km.

Regional flood management by combining soft and hard engineering solutions, the Norfolk Broadlands

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.

A transboundary depoldered area for flood protection and nature: Hedwige and Prosper Polders

The Hedwige-Prosper polders project is part of the Belgian Sigma Plan: this integrated plan is reinforcing dikes and quay walls and opening flood areas to protect land along the Scheldt Estuary and the upstream basin against floods. In this specific project, the outer defences of the Hertogin-Hedwige (hereinafter referred to as Hedwige) and the Prosper polders – low lying areas of reclaimed land are being removed, reopening these areas to the tides.

Restoration of the Oka River’s upper estuary, part of the Urdaibai Biosphere Reserve

The estuary of the Oka River is located within the Urdaibai Biosphere Reserve, on the coast of Biscay, Basque Country, north of Spain. It is an area of high ecological value. Its landscape has been transformed over the years by human activities, as it has been inhabited since Prehistoric times. The most important activities affecting the landscape of the estuary have been agriculture, cattle rising and a shipyard. While the first two have practically disappeared, the shipyard activity is still on-going, although with less intensity than in previous decades.

Rainwater saving and use in households, Bremen

In Germany, for a long time a single fee for both rainwater and wastewater was levied in all communities. After some German court decisions the fee for rainwater was separated from wastewater one and is now based on the extension of impervious property surface (m2), which directs water into the public sewage system. Collecting rainwater on private property with e.g. rain barrel or infiltration system (as for example green space) is then likely to reduce sewage costs due to lower loads to be treated by the treatment plant.

Flood risk management for hydropower plants in France

Hydropower is an essential part of the energy mix in France, accounting for around 20% of installed capacity. Climate change is projected to increase the frequency and intensity of extreme precipitation events and to accelerate snowmelt, which would result in increased flood risk. Flooding can adversely affect dams causing overtopping, outages, damage to equipment and adverse downstream impacts. It is essential that dam operators take these risks into consideration and implement adaptation measures as needed.

IRRINET: IT irrigation system for agricultural water management in Emilia-Romagna, Italy

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.

Use of insurance loss data by local authorities in Norway

Losses and damages related to urban flooding and storms are likely to increase due to climate change. The insurance industry can potentially play a key role in climate change adaptation by contributing to the understanding of risks associated with climate change. By sharing data on the location of insurance claims associated with extreme rainfall or storms, the insurance industry can enable better-informed adaptation planning and risk management.

Flood defence framework for National Grid substations in United Kingdom

The United Kingdom has historically experienced severe flood events, including that of summer 2007, which resulted in the loss of essential services including water and energy supply, as well as the destruction of infrastructures, with estimated costs exceeding £3.2 billion. About half a million people were immediately affected by this event, in terms of temporary absence of energy supply. In any of such flood event, once energy supply is impacted, so are other services as water distribution, transport, communication and health care.

Environment-friendly urban street design for decentralized ecological rainwater management in Ober-Grafendorf, Lower Austria

The municipality of Ober-Grafendorf is located at an elevation of 280 m in a typical pre-Alpine landscape in the Mostviertel region in the western part of the Austrian province Lower Austria. With 4,612 inhabitants on a municipal territory of 24.6 km2, Ober-Grafendorf has a population size only slightly above the statistical average of Austrian municipalities, and it is among the 98% of Austrian municipalities with less than 20.000 inhabitants.
