WWF’s Danube-Carpathian Programme, together with residents of Mindya (Veliko Tarnovo), reconnected the Veselina River to a former meander near the village. When the bend was cut off in the past the channel incised by ~150 cm, so a low sill was built (works 2007–2008) to raise water levels and route flow back into the old course.
The reconnection now creates slower, warmer waters that support breeding habitat for fish and birds and add retention during high flows.
Project timeline: initiated 2005, works completed April 2008; total cost ≈ €76 k funded by WWF and the DOEN Foundation. The reach lies on WFD water body BG1YN130R029, classified as HMWB.
In May 2012 the site was legally designated the “River Veselina” Protected Area, announced by the Ministry of Environment and Water on the International Day for Biological Diversity; the designation explicitly includes the restored meander. The protected area covers about 98.6 ha between Kapinovo and Mindya.
Since designation, local biodiversity work has documented amphibian and reptile assemblages within the protected area, adding evidence of habitat value.

Along the Ill between Colmar and Strasbourg, a basin-wide programme combines classical flood protection (dykes, optimisation/automation of barrages) with NWRM (riparian forest restoration, oxbow reconnections, stream re-naturalisation) to lower flood peaks, increase storage, curb erosion and enhance biodiversity. Initiated by the former Alsace Region, delivery today is ensured by the mixed association now called “Rivières de Haute-Alsace” (created in 2017; name adopted in 2020). The 2014–2024 Ill management scheme (~€19 m) included major works at Erstein’s Steinsau barrage: full refurbishment with a fish pass equipped for video-counting and six fish-friendly Archimedean screws for hydropower; Steinsau and nearby Boeschey are presented locally as multi-functional (flood safety, ecology, leisure, energy). The strategic framework continues in cycle-2 planning: the 2022–2027 Flood Risk Management Plan for Rhin-Meuse keeps priority on risk reduction, nature-based retention and space for rivers, while the SAGE “Ill–Nappe–Rhin” remains the operational reference (CLE renewed by prefectural order on 16 May 2024). Natura 2000 objectives in the Grand Ried also support reconnection and management of side arms to sustain floodplain habitats and functions.

Gerai (Balta Geraiului), a Danube floodplain between Gârcov and Islaz, was restored under the LIFE+ “Green Borders” project. Works completed in 2011 reinstated the hydrological regime on about 1,000 ha to secure breeding water levels and open-water patches for Ferruginous Duck (Aythya nyroca) and Pygmy Cormorant (Microcarbo pygmaeus). Since then, the area has gained stronger protection and outreach: on 13 June 2012 it was designated as part of the Olt–Danube Confluence Ramsar Site (46,623 ha), and in June 2013 WWF, APM Olt and local communities opened a visitor observation point at Gerai. Governance has also been updated: in May 2023 Romania approved the official management plan for the Natura 2000 sites ROSPA0024 “Olt–Danube Confluence” and ROSCI0044 “Corabia–Turnu Măgurele”, which cover the Gerai area. Recent pressures include recurring reed/grass fires; in August 2022, over 600 ha around Islaz in the “Teleorman Delta”, including Balta Geraiului, burned. Overall, the project’s hydrological reconnection and bird-habitat aims remain relevant, now framed by Ramsar and Natura 2000 planning, while fire management is an ongoing challenge.

Restoration of the length of the Borova stream, increased by 6.3 km a shallow meandering stream bed, where sections of speedily running water alternated with sections of a slow stream were created, financed by the Ministry of Environment of Czech Republic.
Today this project is still relevant and effective, although it would need reconstruction in places.

The national Landscape Revitalisation and Integrated River Basin Management Program (2010) aimed to curb ecosystem degradation and flood/drought risk by retaining rain where it falls, especially in damaged parts of the landscape. It deployed many small water-retention elements across 488 municipalities, restoring landscape storage via basins, ponds and similar measures. Early phases created ~7,700 seasonal jobs with about €43 million invested; the programme was adopted by Government Resolution 744/2010.
Following a change of government in 2012, the national programme was wound down; only ~4% of planned funds were disbursed and monitoring was not established in time. Yet many structures remained in place. In the Košice region alone, ~250,000 m³ of green/retention works were completed in 2010–2012, and the approach continues there under a region-wide Restoration Programme approved in 2021 with a 2021–2030 horizon. The Ministry of Agriculture is also preparing a ‘Climate Fund for Soil’ to support such measures.

The 75 km-long Vezouze river regulary overflows, leading to increasingly violent floods especially in the urbanized sector of Lunéville, worsen by the degradation of the natural river bed upstream. After the violent 1983, 1998 and 2004 floods, the local municipalities launched restoration work to reduce the impacts of future floods. It involved widening parts of the riverbed by leveling a levee on the left bank. Two one-meter-wide flood channels were excavated over six hectares, creating 60,000 m³ of cleared material. Wetland habitats like ponds and side channels were established, with trees and helophytes planted.

The Salt of Life project (LIFE11 NAT/BG/000362) restored the lagoon’s water-management infrastructure at Atanasovsko Lake by repairing dykes and barriers, dredging 23 km of the perimeter channel and rehabilitating 20.5 km of embankments to secure long-term habitat conditions for roosting and breeding birds. Building on this, Lagoon of LIFE (LIFE17 NAT/BG/000558, 2018–2024) scaled up restoration: three major earth dikes (~5.8 km) were rebuilt, 17.6 km of mini-dikes restored and 14.3 km of internal saline channels cleaned; the North sea sluice was repaired in 2021. These actions increased water exchange more than fourfold, stabilised water levels and salinity, improved oxygen, and reduced chlorophyll-a - directly improving ~220 ha with positive effects across >700 ha. A pilot, low-impact method using a mini-excavator to build/maintain mini-dikes reduced cost, time and disturbance and has been widely applied. Macrophyte recovery advanced with Ruppia maritima transplanted (TERFS/Chimove), establishing three self-reproducing colonies. In 2024, Greater Flamingo bred here for the first time in Bulgaria. An After-LIFE plan and an active Public Advisory Council support ongoing maintenance with Black Sea Salinas, strengthening resilience to extreme rainfall and safeguarding salt-extraction infrastructure and lagoon habitats.

Leidsche Rijn is no longer only “under development”: the VINEX new town has largely been delivered (c. 1997–2025; ~30,000 homes). The original ambition was to retain stormwater on site, minimise imports of poor-quality water, and use extensive SuDS. It has been realised as a near-closed urban water system. Rainwater is stored and infiltrated via wadis/bioswales, canals and ponds; the Haarrijnseplas functions as the seasonal buffer and as a public bathing lake. The system is actively managed by water authority HDSR through circulation and level control with large pumping stations (e.g., Vleuterweide and Terwijde; Vleuterweide’s two pumps move ~107 m³/min). Utrecht has tightened rainwater policy, prioritising reuse → retention/infiltration → discharge and incentivising disconnection from sewers. Routine monitoring now covers wadi performance (annual coring for 10–15 pollutants and renewal of the top layer when saturated); vertical sand/reed filters are used to polish water before inflow to Haarrijnseplas. Recreation and ecology remain integral, with recent seasons reporting good bathing-water status.

The Nagyszéksós-tó project aimed to safeguard the natural and recreational functions of the protected lake area by improving retention of 1.2 million m³ of water from excess periods and supplying surplus water from the nearby village’s treatment plant, with extra polishing in a newly created wetland. Other objectives included enhancing groundwater recharge, restoring drainage capacity to avoid prolonged waterlogging of farmland, and providing Mórahalom with improved recreation, cultural and educational opportunities.
Since completion, the site has become a key habitat, supported by buffalo grazing for vegetation management and seasonal hydrological cycles typical of saline lakes. In recent years, summer drying has recurred, seen by conservationists as a natural phenomenon, though it poses challenges for tourism. A major eco-tourism development started in 2024–2025, led by the Kiskunság National Park Directorate and Mórahalom municipality, will deliver a new visitor centre, thematic trails, birdwatching towers and educational facilities, scheduled to open in 2026, aiming to balance habitat protection with sustainable public access.

The Lippenbroek project, launched in 2006 in Hamme (Belgium) as part of the Sigma Plan, implements an innovative sponge measure that combines flood protection with ecological restoration through a Controlled Reduced Tide (CRT) system. Established on a former 10-hectare polder, the site receives tidal water through regulated culverts, recreating an intertidal environment favorable to freshwater wetland habitats. The objectives were to store floodwaters, restore estuarine habitats, and test the CRT concept for future applications. The results have been highly positive: improved water quality, rapid vegetation development, increased biodiversity, and natural morphological evolution. The site’s success makes it a model for estuarine restoration in the Scheldt estuary.
In 2025, it remains very relevant as a demonstrator site, and still is a research area.
