DTRIP is a partnership project that will use CRF funds to manage restoration work and to deliver habitat improvements in the Dart and Teign catchment. The partnership, led by the Westcountry Rivers Trust, has been working together for many years, carrying out river restoration and addressing the causes of Wa-ter Framework Directive issues.Through restoration work, the project will address issues including: sediment, which has a direct adverse effect on water quality; diffuse pollution from agriculture and roads, which can impact on river ecology and causes WFD failures; barriers to fish migration, preventing fish from reaching habitat where modeling shows they should be present; interrupted conveyance of river gravels, resulting in reduced spawning habitats for salmonids; habitat loss of wetted and wooded land that has an important role to play in improving water quality & quantity; acidified moorland that creates low pH levels that are detrimental to ecological health of the rivers. +

Dam was removed in the River Stenån to help the salmon and other migratory fish to swim upwards the stream. Also other measures to impove fish migration and reproduction has been made by biotope improvements. Wood depris and rocks and gravel has been added to stream bed. Now the stream meanders and flows through a lovely maple forest.
Also the stream and lakee in the Stenån water system are acidified and limed since 1986. +

Day lighting the channel as the brook is in culvert for the entire length of the park. Re-naturalisation and Water Quality improvement works. Biodiversity, access to nature is a great attraction. North to south walking route. Possible flood storage area<br>RRC have been asked to conduct a scoping report (Dec 2010) and are set to go out on site in Jan 2010. +

Daylighting of a previously culverted stream in a suburban area. The culvert was old and under dimensioned, thus it had to be either exchanged with a larger culvert, or removed. Based on a cost-benefit analysis, the latter was chosen, and the land owner decided on three main goals for the daylighting: 1) improve the water quality to good ecological status, 2) reduce bank erosion after removing the culvert, 3) increase the natural recreational area within this suburban zone.
The project was planned and prospected in 2015, the daylighting, flood protection and reconstruction of the riparian zone was conducted in 2016, and monitoring was conducted in 2017 and 2020. +

De Astense Aa was een rechte beek met steile oevers. Door deze eigenschappen wordt water snel afgevoerd. Dit zorgt voor wateroverlast bij extreme neerslag en voor droogte in periodes waarin het weinig regent. Dit is geen ideale situatie. Daarnaast was de situatie ook niet zo aantrekkelijk voor planten en dieren. Daarom richt het waterschap Aa en Maas de Astense Aa in fases opnieuw in. +

De Beekloop is voor het grootste deel gegraven door de mens en ontspringt in de bossen tussen Aalst en Hezen en uitkomt in de Kleine Dommel ter hoogte van natuurgebied Hulsterbroek. De waterloop ligt bij de overgang van het Kempisch plateau in België tot een lager gelegen gebied in Noord-Brabant, wat resulteert in een relatief groot bodemverhang. De beekloop is betrokken geweest bij vele beekherstel projecten tussen 2010 en 2015, waarbij sommige projecten geclassificeerd kunnen worden als traditioneel beekherstel (TB) en sommige projecten met de focus op Bouwen met Natuur (BmN). Voor trajecten (152 t/m 159) zijn zowel BmN werkzaamheden uitgevoerd als traditioneel beekherstel (Factsheet NL27_BO_3_2). De belangrijkste BmN maatregel die hier is toegepast is het toevoegen van dood hout. Dit is gedaan over een totale lengte van 750 meter ter hoogte van stuw 't Schut. Daarnaast zijn er ook 6 vispassages aangelegd en is er beschaduwing toegepast. +

De Doorbraak is a newly created stream near Almelo. Its creations has several purposes. In terms of water quantity, the stream helps create more space for inundation, so that there is less of a need to discharge water out of the area. This is supposed to help retain more water in the region in wet periods and prevent drought in dry periods. De Doorbraak is also part of a plan to improve the water quality of the Regge basin. It contributes to a separation of urban and rural waters, so that less polluted water ends up in the Regge. To achieve this goal, an underpass is created in the Twentekanaal, so that its more polluted water does not mix with the cleaner Doorbraak water.
Finally, this stream provides and ecological link between Twente in the northeast and the hills of the Sallandse Heuvelrug in the southwest. The topsoil of this stream valley was removed over a length of 13 km and a width of 50 m. This created a large area that the stream can inundate. Abandoned meanders and pools were conncted to the main stream. Vegetation removal is managed by grazers, with additonal mowing, if necessary. +

De Lactariabeek ontspringt in Limburg. Deze beek ligt in een natuurlijk beekdal. De beek is daarom getypeerd als (R4) langzaam stromende bovenloop op zand. De beek is op veel plaatsen sterk genormaliseerd en vergraven. Toch heeft de beek hier en daar nog steeds een natuurlijk verloop. Op de Brabants-Limburgse grens kruist de beek het Afwateringskanaal met een sifon. De beek loopt deels door een bosgebied, waar de beek in de zomermaanden kan droogvallen. Vervolgens stroomt hij door een gebied met overwegend landbouw. +

De-culverting of the existing Norbury brook; re-alignment; in channel works; possible wetland creation and assessing the likely flood risk benefits using the river Wandle ISIS model. Reasons for enhancement:<br>Biodiversity; Visual amenity and access to nature; Possible FRM benefits; Inclusion of climate change Adaptation +

De-culverting through the park & re-naturalisation of the river. The Cran Brook flows through Valentines Park and has been straightened and encased in concrete. This linear section of the brook comprises an artificial channel with stepped terraced banks. +

Debenham (Map 1) has suffered from historic flooding, most notably in 1912, 1936, 1937, 1944, 1947, 1956, 1968 and 1993. Managing flood risk in the village town is complex because 3 tributaries of the River Deben meet in the village and the costs of many traditional flood management measures are prohibitive. This case study uses hydraulic modelling to assess the effect of 10 Natural Flood Management (NFM) features on flood risk in Debenham and establishes their effect on property damages for a range of return periods.
Modelling has shown that installing 10 NFM features providing 34,250m3 of storage across 3 subcatchments (~34km2) that drain in to Debenham would reduce the annual average damages to properties and farmland by 31%. The proposed NFM measures would also reduce the total numbers of properties at risk of flooding across all return periods. For the 1 in 10 and 1 in 20 year flood events, installing NFM features reduces the risk of flooding for 24 properties. Total damages to properties across all return periods would be reduced. For example, for the 1 in 75 year flood event installing NFM features would reduce total property damages by £421,400. +
W
Deculvert River; provide walk as part of water link way; river edge planting; re-meandering. Channel currently within culvert under car park. Deculverting removes fish blockage and enhances habitat. +
F
Deculverting and naturalisation of ordinary water course and control of non native species. Site is planned to be developed, mitigation for this development with nature conservation improvements as well as potentially providing amenity and recreational land for local population and education opportunities. +
B
Deculverting of Whitton Brook. One aspect of the Big Yellow storage development. +
P
Deculverting through Parloes Park and naturalisation. Bank improvements and creation of features, creation of associated wetland areas in Goresbrook Park. Flooding of Parsloes occurs during intense rainfall events, the manholes blow their lids. Flood risk could be massively improved. The Gores brook is culverted through Parloes, so this would perhaps have priority. +

Deculverting through the park. Scope for accompanying lake enhancement/ fisheries project. Loxford Water is heavily urbanised, degraded and a in a concrete culvert for the most of its length. Through the park there is space available for re-naturalising the river. At the moment it is fully concreted bed and banks or rip-rap further downstream adjacent to the lakes. +
