N
Deculverting; bank naturalisation; introduction of pools and riffles. Planning obligation with the developers to restore the Wandle through the site. +
S
Deculverting; installation of a fish pass. The Wandle is culverted through the Shepley Mill site, fragmenting the river corridor which impinges on fish passage through the Wandle and would also be a major barrier to other wildlife moving along the corridor, including any future released water voles. +
H
Deflectors installed along the Hogsmill river to improve habitat +
S
Deliver practical work such as habitat creation and restoration +
R
Delivery of DWPP actions to address land use impacts and to implement river improvement in the Loe Pool SSSI catchment. Dirty water separation, slurry lagoon improvement, soil management, track interception and other capital interventions +
E
Des échancrures ont été réalisées sur 14 ouvrages
dont la hauteur de chute oscille entre 1 et 2 m. En
outre, le maintien des ancrages et d’une partie des
ouvrages permet de préserver une certaine capacité
de retenue en amont lors de la montée des eaux
(effet local et temporaire de rétention). Globalement,
le parti pris a été de ne pas aménager le cours
d’eau, même lorsqu’il présentait des élargissements
après effacement, afin d’observer la dynamique
de reconstitution de sa morphologie « naturelle ».
Néanmoins, des banquettes enherbées et des plantations
d’arbres et arbustes d’essences locales adaptées
ont été mises en place au niveau de cinq ponts et de
plusieurs seuils, dont les surlargeurs étaient les plus
marquées et les plus visibles des riverains, afin de
resserrer le lit mineur et diversifier les faciès d’écoulements.
D’autres mesures complémentaires ont également
été réalisées comme la pose d’abreuvoirs et
la création de fosses pour abriter la faune piscicole. +

Restore riparian floodplain habitats maintained in reserve "Dolna topchia" and run off on his sleeve "Malka Tundzha" +
Design and construction of hydraulic structures on river Tundzha for recovery of riparian wetland biotopes maintained in reserve "Dolna topchia" and run off on his sleeve "MalkaTundzha."
The main objective of the project is to restore the conditions necessary for the maintenance of riparian biotopes. Main habitat is riparian floodplain forest - habitat code 91F0. There is good population of spring snowflake. The target of the project area is maintained reserve category " Dolna topchia " and is part of the Natura 2000 network –protected area "Reka Tundzha 2." To achieve the objective was built weir on the Tundzha river and channel with length of 900 m. The water intake includes the diversion weir, stilling, primitive channel, fish passage and water intake facility.
Through the construction of channel and water intake facility is carried out gravity connection between the river and sleeve " MalkaTundzha" by drainage channel along an existing irrigation canal that expanding, allowing hydration of 467.6 ha of habitat 91F0. The channel is lined and the bed of the "MalkaTundzha” will supply the groundwater in the area of the reserve. After the feedback between " MalkaTundzha " and river along the southern border of the reserve "Dolna topchia" will be implemented consistent circulation of water in reserve. +
Desire to enhance the brook has been flagged up in the revised management plan for Richmond Park. To create some inchannel and bankside diversity through a techniques such as timber fenders and marginal berms to encourage growth of plant species where poaching is less of an issue. Longer term benefits could include suitable habitat for water vole. Benefits for important bat populations, fish etc. Previous thoughts have raised potential for flood storage too. Straight channel with minimal inchannel and bankside vegetation. Heavily poached by deer and dogs in the channel. Extensive use of bank by people. No riparian vegetation. Channel is used by bats and kingfishers however.<br>

Environmental restoration of the lower section of the river Narcea in the municipalities of Salas and Pravia (Asturias) +
Despite its good condition, riparian forests are under human pressure (pipelines, agricultural practices) that have reduced its size and fragmented it. The pipelines have altered the natural processes of adjustment of the channels. Narcea River is one of the most important rivers in the North of Spain.
The main actions of this project are creating a river corridor and removal of the structures that limit the development of natural geomorphic processes; control of invasive species and ways to improve the composition and extent of riparian forest; actions to mitigate the impact of flooding; comply with the requirements of the WFD. +

Strengthening associated biodiversity of habitat 92A0 and control of Invasive Alien Species in the Segura River (LIFE + Ripisilvanatura) +
Despite the Segura River makes its way in many through unique vegetation in many sections of the stream, the riverside or riparian forest (ripisilva) is in serious danger due to the threat of invasive species which are gradually occupying its space. LIFE project "Ripisilvanatura" aims to control the expansion of Invasive Exotic Species existing on the riverbanks of the Segura River and promote the colonization of the riparian forest by native species.
As mentioned before, the main objective is to promote the recovery of the riparian forest, specifically of the habitats of Community interest 92A0 and 92D0 as well as their associated main habitats in the most degraded area of that habitat through the Segura River which is located after the largest reservoir of the entire basin (Cenajo reservoir). It is an area of maximum condition and progressive deterioration of the habitat corresponding to the Vega Alta del Segura in Moratalla, Calasparra and Cieza.
To achieve this goal, the project aims to fight against Invasive Alien Species (IAS) since they have colonized the original niche of such habitat. AIS are the key actors of the substantial problem for the River Segura in the Region of Murcia; the loss of primary habitat is an advantage for opportunistic species of both fauna and flora, entailing an obvious loss of the rich biodiversity that was traditionally linked to the Salicaceae and Populus ripisilva. Thus the main strategy pursues the recovery and protection of riparian forests from the middle course of the river basin in the stretch including the municipalities of Moratalla, Calasparra and Cieza by controlling invasive alien species primarily within the habitats listed as “priority” because the species of fauna that are the subject of this project find their niche in these habitats.
Fulfilment of the following specific objectives set will enable the success of the project:
• Creation of a green infrastructure between the two riparian nature reserves of the region.
• Regeneration and protection of the priority habitats of community interest and the habitats of interest associated with the river.
• Protection and conservation of priority and European special protection fauna.
• Elimination of invasive exotic plant species through hands-off management.
• Removal of ichthyofauna and exotic birds via citizen engagement and the competent administration.
• Prevention and eradication of fires along the riverbed.
• Creation of a Land Stewardship Network for the Vega Alta.
• Provision of ITCs as a very versatile tool for the fight against IAS and biodiversity conservation.
• Generation of protection measures for the threatened pre-existing ripisilva clumps.
• Publication of an Integrated Management and Control Strategy on Invasive Alien Species

Deux types de techniques de restauration ont été
testés en 2008 et 2009:
• 2008 : recharge en granulats employée seule;
• 2009 : retalutage de berges (déblai-remblai) et
recharge en granulats;
La présente fiche de retour d’expérience correspond
à la première phase test : recharge en granulats employée
seule.
Un apport de matériaux sur 30 cm d’épaisseur (en
moyenne), soit 400 tonnes de granulats, est fait dans
le lit du cours d’eau. Les matériaux sont composés
d’un mélange hétérogène de blocs, de pierres, de
cailloux et de graviers de granit issu d’une carrière
proche correspondant à la même nature géologique
que ce tronçon de cours d’eau. Les granulats dominants
composant la couche d’armure de ce type de cours d’eau en bon état sont composés de cailloux
et de petites pierres (16 à 128 mm). La disposition
hétérogène des granulats permet également de
reconstituer par pincement de la lame d’eau un lit
d’étiage dans les portions sur-élargies et de profondeurs
faibles et homogènes. Le rehaussement d’une
partie du lit mineur et la variation des épaisseurs de
sédiment (de 10 à 50 cm) permettent également de
reconstituer des faciès d’écoulement rapide dans les
portions qui en étaient dépourvues.
La recharge en granulats n’étant pas suffi sante pour
compenser l’incision du lit, deux microseuils et une
rampe latérale enrochée sont réalisés pour assurer la
franchissabilité de l’ouvrage amont (radier de pont
dénoyé). Une assise en gros blocs libres sélectionnés
à partir du tri manuel des éléments les plus grossiers
livrés par le carrier, est posée sur le fond du lit (sans
ancrage ni pose de géotextiles). Cette base a été
recouverte du même mélange de cailloux, pierres et
blocs utilisé pour la reconstitution du matelas alluvial.
Une pêche électrique de sauvetage est réalisée juste
avant les travaux. Les petits poissons sont stockés sur
une source latérale en vivier et remis en place à la
fi n du chantier. Les plus gros, plus diffi ciles à garder
en captivité, sont déplacés à l’amont immédiat de la
zone des travaux

Diffusing the Issue is a partnership project that will use CRF funds to improve watercourses in areas of the Ribble Catchment that are intensely farmed. Diffuse pollution, poor habitat and obstructions to fish passage are causing certain watercourses in these areas to fail to meet the required standards under the Water Framework Directive (WFD).
Work has already been undertaken by the Environment Agency and the Ribble Rivers Trust to address the reasons for failure. In order to ensure that the priority waterbodies achieve Good Ecological Status under the WFD, the creation of riparian buffer zones, farm infrastructure improvements and the reconnection of habitat are necessary. Through targeted farm visits, the Ribble Rivers Trust will seek to identify ways in which diffuse pollution can be reduced, in a way that is sustainable and beneficial to farmers and landowners, as well as the environment. +

Dike realignment took place utilising an area of former brickwork factory. The floodplain was widened by 200 meters and a new secondary channel created. The works also improved habitat connections, by increasing vegetation in the floodplain which will mature over time. The site is now popular for recreation, specifically for water sports, with Arnhem residents.
The channel capacity has increased to allow for significant changes in flow. There has been little effect on biological quality with regard to Water Framework Directive targets, as fish and benthic invertebrates were not monitored before the works were carried out. +
