Flood protection

Persistently low water levels on the Moson-Danube since 2002, caused by the sinking of and loss of supportive effect from the Danube, caused severe ecological, agricultural and water flow problems (Reference 12). The project, funded by the EU through the Széchenyi Development Plan, was aimed at improving water management and rehabilitating the degraded ecosystem of the area (Reference 1).
The project consists of two phases: the reconstruction and regeneration of the river in the entire Moson-Danube area, and the creation flood gate at the delta. The first phase was completed in 2015, the second phase started in 2017 and is planned to finish in 2021 (Reference 12 and 13).

This intervention aimed to address low water levels and low water quality in the Sandall Beat Wood and Cantley Park. The problems have been identified by the council and this project was planned to improve the water levels as well as the water quality. This also helped in improving the gross water flow of the regions and protected the wetland habitats. In addition to the above-mentioned benefits, the project successfully engaged local communities. (Ref 2).

"Renaturation and flood control works on the Grémillon stream are being undertaken in the Nancy agglomeration. The stream is subject to overflows and was highly artificialized during the urban development of the Nancy agglomeration, which caused a slow degradation of the natural environment during strong storms. In order to solve these problems, Grand Nancy has decided to implement a set of measures designed to protect the populations from overflowing of the stream and to support the regaining quality of the natural environment"(Ref. 1).

Green public space in the city with 60 new trees, large lawn areas, two water features and a rain garden that manages the site’s surface water. (2) This diversely planted area will manage surface water for the northern half of the space, improving the city’s flooding resilience and establishing an ecologically rich habitat in a part of the city that is still recovering after the banks of the River Aire burst in December 2015. (3, 4) The space serves as a gathering place for workers and visitors, providing a place for rest and reflection among natural elements. (5)

The £1 million project aimed to transform the area from arable land to a high-quality wetland by creating a number of interconnected reed beds and water bodies. The project recreates part of the old wetland landscape that used to exist on the edge of Doncaster 200 years ago before it was drained for other uses. A major benefit of expanding the wetland will be to provide better quality water for local communities and reduce the impact of flooding in the area. The project is a collaboration among WWF, HSBC, Yorkshire Wildlife Trust and the European Union. (Ref 1)

The once rich in fish Nidda river in the north of Frankfurt was canalized and dammed in the 20th century. River loops were pierced, filled in or made into oxbow lakes. Newly built weirs stopped the fish migration. The expansion provided good protection against flooding, but the river became a canal (2).
In the 1990s, the Nidda neighbours developed a program for the renaturation of the river, the concept "Natural Nidda". It was decided by the city council of Frankfurt am Main in 1998 (2). The project consisted of many measures aiming at the restoration of the natural course and ecosystem of the Nidda river, the creation new habitats for flora and fauna, the expansion of the floodplain area and thus the river's retention capacity, the deconstruction of weirs, the renovation and building of bridges and the reconnection of disconnected branches of Nidda. Besides the environmental aspects, another project goal was to make the riverside more accessible for local offering various ways for relaxation and recreation. (2,7)

The major objective of the project is the ecological recovery of five of the most important lakes of Bucharest in order to strengthen its tourist potential and attract new investments and tourists. The following lakes went under construction: Băneasa, Herăstrău, Floreasca, Tei, Pantelimon II. (1)

The project area comprises the morphological floodplain of the Rhine to the north and south of the city of Karlsruhe and sections of the river Alb, covering an area of about 7.665 hectares in total. Alongside Karlsruhe, five smaller communities in the neighbourhood contribute to the project as partners. Due to the channelling of the Rhine, the construction of dykes and the isolation of river channels, the area has lost its natural floodplains and precious habitats and became more vulnerable to flooding. Major objectives of the project are the re-introduction of natural floodplains and the enhancement of natural habitats for local flora and fauna. (Ref. 7). The project included an exceptionally wide range of measures including species protection measures, the complete desludging of parts of the Rhine, the re-establishment of softwood and hardwood forests typical of the floodplain, the construction of bridges, the natural remodelling of the entire river Trench systems and the creation of new bodies of water. (Ref. 9) The project also provides environmental education, informing the public about activities and encouraging their participation (Ref. 7)

The Mab Lane Community Woodland was planted on a former playing field at Mab lane and Croxdale Road West in Liverpool. It is a part of the larger Mersey Forest initiative which has been increasing the amount of woodland and green spaces across Cheshire and Merseyside since 1991.
The new woodland which has a network of native trees, wildflower meadows a community orchard as well as seasonal wetland areas and footpaths, was officially opened by the local community in 2010. It also includes new pathways for walkers and cyclists and areas for family picnics (Ref. 2, 10). Mab Lane Community Woodland is a partnership project involving the Forestry Commission, Northwest Development Agency, Mersey Forest, Big Lottery, Riverside Group, Liverpool City Council and the Local Community (Ref. 10).

46.5 hectares of nationally-important habitat was restored in Doncaster as part of an Environment Agency-led project benefiting communities and wildlife. The work across seven woodland areas was designed to help improve water quality, reduce flood risk, and enhance natural habitats for protected species. By providing additional flood storage the project is able to help attenuate both peak and flood flow from rainfall events, reducing flood risk and damage and reducing the financial and carbon cost of pumping water from the Torne catchment. Although this project extended beyond Doncaster, Sandall Beat in Doncaster was part of the key sites (Ref 1).
