The Role of Runoff Attenuation Features (RAFs) in Natural Flood Management
Round 1
Reviewer 1 Report
The major issue addressed in the paper include:
Natural Flood Management (NFM). Under this theme the paper tried to focus the role of run off attenuation features (RAFs) in NFM. The focus of course covered solely on the UK catchment based measures. The literature review sufficiently covered RAFs, what they are and how they can be explained. Moreover, the paper covers recent development of RAFs in the UK and original thinking on the RAFs for the future. Having said that, the paper missed the opportunity to highlight for the readers more recent development in the area of NFM and RAFs in the UK. Presentation of the state of recent socio-economic and political developments in the UK have been missing. NFM or RAFs programs in the future cannot be seen in isolation. In the recent future, a major global climate change event is going to be held in Egypt where 200 member countries of the UN will participate. Unfortunately, the UK's participation expected to be low key. The new PM has refused to attend this global event on climate change to be held in the Middle-East.

Reviewer 2 Report
The work deals with a very interesting topic, NBS for flood control.
It makes an overeview of some techniques adopted and highlights the positive and negative sides of the use of the RAF.
Throughout the work except for the dimensions of the reference catchment area, no design engineering data and actual values ​​of the effects of these attenuation techniques are given, but only qualifying adjectives are used, it would be useful to have orders of magnitude on the speed reductions , on stored volumes and on the flood attenuation effect. Another important fact that is only mentioned is the maintenance of these devices (burial due to sedimentation, water treatment due to the accumulation of pollutants). Line 256 also talks about the possibility to cut into a riverbank and create a swale to carry flow onto a floodplain and into a pond or wetland, but it is not taken into account for what type of event to do this operation because in severe events the overtopping embankments become a problem rather than a solution.

The work has been improved and I think it can be published
