Woodland

Woodlands can help to attenuate floods through a number of hydrological processes, such as the interception of rainfall, increased use of water (evapotranspiration), and increased infiltration of water into the soil profile.  Woodlands also act to slow surface runoff and reduce sediment transport down hillslopes, by increasing the resistance to flow. Upland areas, which have higher rainfall, steeper slopes, gullies and often quite shallow soils, can deliver significant amounts of floodwater from headwaters to the lower catchment areas. Well sited and managed woodlands protect the soil from disturbance and improve soil structure due to the action of tree roots and high inputs of organic matter. These conditions enhance the soil infiltration pathways and the water storage capacity thereby reducing direct surface run-off, erosion and sediment transport.

Prioritising research and development gap opportunities for river woodlands report now published

A report has been published by CREW on prioritising research and development gap opportunities for river woodlands. The report was authored by a team of scientists from the James Hutton Institute and University of Aberdeen. River woodlands (RW) play a crucial role in protecting river ecosystems, for example by reducing flooding, storing carbon, filtering pollution, and benefiting local communities. However, nearly 55% of surveyed riverbank in Scotland show poor RW health. This highlights a need for RW restoration. This project aimed to:

Research article on the development of a decision framework selecting between riparian management measures for farmed land now published

A paper has been published on the development of a decision framework for selecting between riparian management measures for farmed land. The open access paper and tool is published in Water and Environment Journal and is authored by a team of scientists from the James Hutton Institute and Teagasc (Ireland). Agricultural mitigation measures should be correctly designed and sited to make effective barriers for diffuse pollution.

Paper published on the hydro-geomorphic effects of wooden leaky barriers in a steep headwater stream

A paper has been published on the hydro-geomorphic effects of wooden leaky barriers (LBs) in a steep headwater stream. The open access paper is published in Earth Surface Processes and Landforms and authored by a team of scientists in the James Hutton Institute. It focuses on a series of leaky barriers installed in a steep headwater channel of the Tweed. Detailed field monitoring and two-dimensional hydraulic modelling (HEC-RAS 2D) were used to assess the hydraulic impact of the structures and associated geomorphic changes.

Working with natural processes - webinar recording now available

A webinar recording is now available that summarises the new Working With Natural Processes Evidence Directory update. 

Working with natural processes (WWNP) aims to protect, restore and emulate the natural functions of catchments, floodplains, rivers and the coast to reduce flood risk. It is also referred to as natural flood management (NFM). The 2025 update report brings together evidence from natural flood management studies published after 2017. 

The webinar was hosted by the Environment Agency.

Working with natural processes: Evidence directory update published

The Environment Agency have published an update to the Working with Natural Processes evidence directory. This was developed in collaboration with JBA Consulting. 

The Working with Natural Processes Evidence Directory was first published in 2017 and captures what research says about NFM. Evidence of NFM has grown in recent years, building our confidence in the flood risk and wider benefits these approaches can bring. Therefore this update report brings in the latest evidence. 

Outputs from Scotland’s Flood Resilience Conference now published

Scotland’s Flood Resilience Conference 2025 was held in Edinburgh on the 28th and 29th January. The theme of the conference was on taking action to implement the Flood Resilience Stratergy. Organised by Verture, the event built on Scotland’s first National Flood Resilience Strategy, published in December 2024. With sub-themes of People, Place and Process and multiple breakout sessions, the event aimed to share good practice, inspire and provide learning opportunities to establish a new level of cross-sector collaboration.

Introducing SpongeScapes: Enhancing Europe's Climate Resilience with Sponge Measures

SpongeScapes is a Horizon Europe project uniting 14 case studies across Europe to advance the understanding and implementation of sponge measures—nature-based solutions that restore landscapes' natural capacity to absorb, temporarily store, and slowly release water. These measures play a vital role in mitigating floods, droughts, and other climate impacts while delivering co-benefits such as improved water quality, biodiversity, and community well-being.

What can be learnt from working with a community to identify what flood risk management measures are needed, are acceptable and which deliver the greatest multiple benefits?
The 'Land management for increased flood resilience' report was published by CREW and authored by Spray et al., (2015).  The main objectives of the project were to undertake: A large scale survey of farmers’ attitudes to NFM and to the use of potential policy instruments to promote its uptake and delivery; andFarm-scale economic analyses of the impact of NFM measures under different scenarios.See - https://www.crew.ac.uk/publication/land-management-increased-flood-resilience
In 2016, SEPA published this handbook to help local authorities and landowners implement NFM
