In the Q-NFM project, part of the NFM Programme, we want to constrain model uncertainties at the micro-scale using accurate measurements, so we can reduce uncertainties when we try to model the effectiveness of NFM at the macro-scale.
Whilst we have developed a modelling framework capable of scaling up hillslope processes and hydrodynamics around channels in flood, we have been recently getting to grips with modelling the micro-catchments, including the everyday issues faced by hydrologists.
The image is from some preliminary micro-scale modelling where telemetry from recent storms is being used to attempt to model different types of NFM – this example shows hydro-hedges at Stock Beck, Cumbria.
Barry explained how Q-NFM are working to scale things up, but also other types of new evidence are still needed to improve large scale and whole-system models.

Lydia gave an overview of the the work of the Environment Agency’s flood risk research team and how they identify research needs and deliver applied research which fills gaps in policy and practice. She explains the Environment Agency’s NFM research framework. In particular she covers work that summarises evidence behind NFM and how it has informed Government policy through the 25 year environment plan and how it is being used by practitioners implementing NFM schemes. She also describes current research on Carbon offsetting and Sustainability.
Integrating local knowledge in to NFM work: Insights from lowland catchments in the Landwise project

The Landwise project is looking at how effective land-based natural flood management (NFM) measures (such as woodland planting, changes to land and soil management and woody dams) may be at reducing the risk from flooding from surface runoff, rivers and groundwater in groundwater-fed lowland catchments. Integrating local knowledge with technical field and modelling work is a key feature of the project.
Chris and Angie spoke about their work bringing together local stakeholders with knowledge on current land use and management to find out which types of NFM measures they believe are acceptable (both culturally or socially) and feasible in certain landscape areas across the West Thames area. They presented preliminary findings from a recent farmer knowledge survey and from a series of NFM scenario building workshops. They outlined how outputs will be used to create catchment scale scenarios for modelling experiments to look at how land-based NFM could affect flood risk. Finally they shared some learning on their top tips for stakeholder engagement concerning NFM.

Ian talked about his research, in particular the outputs of the COMPACT project, a NERC funded project, under their Soil Security Programme This involved investigation of the impact of arable and pastoral land management practices on soil health and structure, focusing on the process of soil compaction, and second, the link between field scale variations in compaction and catchment scale flood risk. It identified significant spatial variations in soil physical properties, using traditional sampling approaches, CT scanning and Ground penetrating radar.

Cover crops as catchment management measure
Click here or on the image below to access the recording. Password 3mGm643i.
Summary: Water companies are increasingly looking into catchment management strategies to deal with floods, water pollution and water scarcity. Measures based on cover crops are known to mitigate these issues as they slow down runoff, increase infiltration and soil cohesion. However, to support the design and prioritisation of investment decisions in their catchments, catchment managers need evidence about the magnitude of cover crop benefits at catchment scale, and the sensitivity of those benefits to species mixes and spatial coverage. Related to the BBSRC funded project ‘Using roots to bio-engineer soil’, Andrea’s talk covered the combined use of lab controlled trials and modelling to assess the effectiveness of cover crops on infiltration and soil erosion in the River Lea catchment.

Working with farmers and landowners to help them adopt management practices that realise benefits including flood risk reduction and biodiversity enhancement whilst at the same time using supporting them to improve soil and pasture health, and their bottom line.
Niels is a researcher, adviser, educator, designer and tree nurseryman. His goal is to help create regenerative landscapes and farms in the UK and Europe, with a focus on agro-ecological systems that are low maintenance yet productive.
Niels delivers specialist training courses for farmers, growers and land managers across the UK. He advises on: soil health practices; planned grazing; agroforestry; whole-farm planning; infrastructure: water, fencing etc; composting & manure management; monitoring of soils & pasture; on-farm trials.

Optimising NFM in headwater catchments to protect downstream communities. Moorland restoration, including gully blocking, Sphagnum reintroduction and upland woodland planting.

The UK supports 15% of the world’s blanket peat cover, but much of this vital resource is significantly degraded. As such, the restoration of eroding UK peatlands is a major conservation concern. Landscape-scale restoration through the re-vegetation of bare peat and damming of gullies is extensive in areas of upland Britain. Understanding the hydrological impacts of these restoration interventions is critical for flood risk management. Martin and Emma talked about their research in the Southern Pennines.
