The Natural Flood Management (NFM) manual
The Natural Flood Management Manual provides information to help practitioners select and implement natural flood management measures.
Documents
The natural flood management manual was published by the Construction Industry Research and Information Association (CIRIA) in May 2022. It can be downloaded for free from the CIRIA product page C802F (subscription required). Once your request is processed you will be able to download:
- the full manual
- part A of the manual - a 23 page overview of natural flood management
- separate graphics which illustrate:
- runoff management
- runoff storage
- leaky barriers
- floodplain reconnection
Summary
Natural Flood Management (NFM) helps to manage flood risk by protecting, restoring and emulating natural processes. The NFM Manual brings together evidence and case studies from the delivery of natural flood management projects. It provides a step-by-step guide to natural flood management measures from identification through to implementation. It’s written for those carrying out natural flood management projects in their local catchment.
Background
This project builds on the findings of the Working with Natural Processes Evidence Directory, which outlined the efficiency of different natural flood management measures.
Approach
The project was developed and co-funded by many of the organisations carrying out natural flood management and published by CIRIA.
The manual
The first section of the manual is a summary guide, which includes an overview of natural flood management and a high-level checklist of implementation steps (this is the extract). The summary directs the reader to later sections for more detailed information. The manual is available to download as a full report or an extract of the first section. Four measures are considered in detail:
- runoff management
- runoff storage
- leaky barriers
- floodplain reconnection
Summary information is provided for a further eight measures:
- upland peat management
- soil and land management
- cross-slope woodland
- riparian woodland
- floodplain woodland
- catchment woodland
- offline storage
- river and channel restoration
