Description: 

This study contributes to addressing the lack of sufficient knowledge base to accelerate wider acceptance and uptake of NbS. It also addresses the question of the effectiveness of different types of NbS (i.e., small- and large-scale NbS) and their hybrid combinations with grey infrastructure in three scenarios: combination of small-scale NbS and local grey infrastructure measures; combination of large-scale NbS and local grey infrastructure measures; combination of small- and large-scale NbS and local grey infrastructure measures. The results suggest that the effectiveness of small-scale NbS is limited to smaller rainfall events whereas the larger (or extreme) events necessitate combinations of different kinds of measures with different scales of implementation (i.e., hybrid measures).
