Advancing the degree of implementation of Natural Flood Management

Abstract

There is great potential to work with natural processes to substantially reduce flood impacts on villages and towns and potentially on our larger cities. Examples have now been shown at several locations that show at the local scale (10km2) that soft engineered structures can slow, store and buffer runoff whilst giving multiple benefits to sediment losses and pollution control. The space created for NFM feature such as ponds, modified ditches, woody debris dams and swales are also sites of improved ecological status and new habitats. The fundamental manipulation of hydrological runoff pathways and the modification of the local hydraulic and energy regimes during flood flow, can have tangible benefits downstream and could form the basis of a broader catchment based approach to catchment management. Projects such as the Belford Project (led by Newcastle and the EA) and other NFM demonstration sites have had high impact in terms shaping government thinking on the NFM potential. NFM is now encouraged by the EA as a viable approach to lower cost flood management, especially for locations that would be expensive to resolve using traditional methods. Newcastle is already working with the EA as part of the Working with Natural Processes Initiative which is seeking to improve NFM uptake in the UK.

However, several barriers to NFM uptake remain and it is hoped that this project will help resolve these issues. The funding structure for NFM and catchment management is piecemeal and fragmented and it is spread across many agencies. The contrast between traditional hard engineering and soft engineering (or nature-based solutions) is still high and a reconciliation between NFM work on local farms and the traditional flood management professionals is needed. The evidence base for NFM, although growing slowly, needs to be accelerated and captured in a compelling manner by using KE strategies that will encourage NFM uptake. Better understanding of River Restoration schemes methods and funding (which is already an ARUP specialism) is needed. How can the established river restoration methods be evolved and moved upstream to smaller streams to look at runoff management at source? Evidence that NFM works at the scale of single features is also strong, hence the need to upscale these approaches is vital. The scaling up issue will be best achieved by using sound scientific arguments based on scaling theory, new models and improved monitoring methods.

To this end ARUP and Newcastle University will create a realistic technological and cost effective funding model to show that NFM can be carried out across larger scales, with tangible benefits, which is quicker, cheaper and easier to deliver. The aim is to show the scientific basis for NFM and how the multiple benefits can be achieved and why. There is potential to further extend the NFM scientific basis into Catchment System Science to show that NFM can play a major role in catchment management in the future. The project team will continue to influence government policy on NFM methods and will attempt to create a new generation of NFM scientists and practitioners in the UK through our CPD courses and high profile publications.

Description The potential for NFM and catchment based management is enormous. However, there is still significant progress to be made to allow these techniques suggested by NFM research to be aligned with the operations and methods used by industry.
Exploitation Route The government and NERC have already started to address the needs of NFM and better catchment management. Significant research funding has been put forward by Defra and NERC to underpin NFM sciences.

There is a need to harmonise river restoration methods , Sustainable Drainage Systems to NFM. Equally NFM must be linked to Ecosystem Services and rural payments in order to exploit the potential of NFM

Description My role as a leading expert on Natural Flood Management, and my position during my internship allowed me to attend many workshops and engagement activities. This high profile role led to my appointment as a special advisor to the government EFRA committee. I was took part in the meetings arranged by the NERC team to create the current funding call for NFM research. The momentum for NFM research and the work of the EFRA Committee has also led to Defra funding £15 Million of NFM trials. In the last 2 years NFM has now become mainstream flood management activity being actively pursued by EA and NGO's. However there is till a demand for more evidence as reflected in the NERC NFM call. There are still many issues to resolve and the few next years will be critical. I feel that traditional consultants and contractors are still not ready for NFM but NGO's and new SME are embracing the technologies behind NFM
