The Construction Industry Research and Information Association (CIRIA) has released a  natural flood management manual.

Natural flood management (NFM) is a tool to help reduce flood risk. It complements other flood risk management approaches and involves working across the landscape to protect, restore or mimic the natural hydrological processes that occur. These include increasing infiltration of water, slowing the flow of water across the landscape, storing water and holding back sediment.

Importantly, natural flood management can have a range of complementary, co-benefits such as habitat creation, carbon storage, water quality improvement and recreational and wellbeing benefits if delivered effectively and considered from the outset. These co-benefits can be maximised by working with others.

The report can be found here.
