Providing Evidence for Natural Flood Management
Our Hydrologists use high resolution surface water modelling to aim to improve the understanding of of the impact of catchment-scale Natural Flood Management.
Evidence for the effectiveness of NFM measures under different rainfall event magnitudes, at the catchment scale, is limited. This is because of the scientific uncertainty about the cumulative impacts of NFM measures within catchments, and the relative immaturity of numerical modelling tools for making predictions about the effectiveness of NFM measures.
Recent innovations have unlocked the potential to quantify the cumulative impacts of many small NFM measures distributed across catchments of varying scales.
A desk-study and catchment walkover were initially undertaken to gain an understanding of the physical and hydrological characteristics of the catchment, then a 2D whole-catchment hydrodynamic model of the catchment was developed.
