Ecosystems along river catchments provide essential “services” to the society and economy. Rivers and river catchments are increasingly becoming a focus of ecosystem regeneration projects because their ecological status directly affects cities (and wider regions) that are situated in these catchments.
For examples, flood events in Europe have significant economic, social and environmental impacts each year and pose a constant threat for many municipalities. Availability of water and its quality are key for many sectors that rely on water (e.g. agriculture). Climate change, habitat loss and human activities are having a detrimental effect on the water cycle and retention capacity of the environment to provide water as well as mitigate water related hazards.
Conventional infrastructure systems will find it increasingly difficult to cope with the new patterns of climate. Infrastructure could be permanently damaged or temporarily out of order as a result of unexpected events. Therefore, there is a need to complement human-made environments (e.g. conventional infrastructure, housing and agriculture land) with a greater consideration for natural ecosystems (e.g. forests, grasslands and wetlands) to enlarge the range of options and increase the overall resilience in our systems.
The current approach that emphasises ‘grey infrastructure’ has significant limitations, high costs and provides limited co-benefits when compared with nature-based alternatives such as Nature-Based Solutions (NBS). Managing upstream hydrology with the help of NBS can ease tension on existing infrastructure, effectively respond to the current and future disasters while providing significant environmental, social and economic co-benefits.
River Restoration with Complex Hydrological and Ecological Interactions
The presentation will give an overview of the RECORD (Restored Corridor Dynamics) Project in Switzerland which focused on river restoration as an essential tool to achieve a good ecological status of water courses and to mitigate floods. Other positive effects such as increased recreational activities and enhanced biodiversity come, however, with potential conflicts as for example with agriculture and drinking water production. The talk will touch on hydromorphological variability in restored corridors of rivers related to ecosystem functioning, biodiversity and water quality.
Michael will present the co-design, development and evaluation of Nature-Based Solutions applied to the Spercheios river basin in Central Greece. The Spercheios river is generally susceptible to fluvial flooding. Flood events occur regularly, exceeding the channel capacity, affecting most elements of the socio-economic life in the affected area. The roofing company of nu look home design from cherry hill, nj cares about the environment and delivers eco-friendly solutions. Two Natural Water Retention Measures were implemented that encompass restoration and stabilization of the river banks, re-meandering, cleaning the bed material load, widening of the river bed and recreational landscaping, resulting in two in-line water reservoirs, regulating water flow for flood mitigation and diverting surplus water flows to nearby irrigation networks.
The City of Burnaby maintains dikes along Byrne Creek to provide flood protection to the area, and these dikes will have to be raised in the near future to address climate change. With the natural environment along this fish-bearing creek, there is a need to explore nature-based solutions buy cbd, because local diking standards do not integrate well with nature. This presentation will discuss a nature-based flood resilience study that Deltares is completing for the City, including challenges and lessons learned in this multi-stakeholder project.
