TL;DR: In this paper, two approaches to risk attribution are discussed: Standards-based attribution, which is a deterministic approach, and sensitivity based attribution which apportions risk between the variables that influence the total flood risk.
Abstract: Flooding in urban areas represents a particular challenge to modellers and flood risk managers
because of the complex interactions of surface and sewer flows. Quantified flood risk estimates
provide a common metric that can be used to compare risks from different sources. In situations
where there are several organisations responsible for flood risk management we wish to be able
to disaggregate the total risk and attribute it to different components in the system and/or agents
with responsibility for risk reduction in order to target management actions. Two approaches to
risk attribution are discussed: Standards-based attribution, which is a deterministic approach,
based upon the performance of different engineering components in the system at their “design
standard”. Sensitivity-based attribution, which apportions risk between the variables that
influence the total flood risk.
Whilst both these approaches are feasible for the small system considered here, in practice
urban flooding systems involve tens of thousands of variables. The only feasible approach to
tackling this problem for large urban systems is therefore by hierarchical simplification of the
system, with the attribution analysis being applied in several tiers of detail. In this paper, the
applicability of a hierarchical approach is demonstrated in the context of sewer pipe blockages.
The results demonstrate the potential of attribution methods to support the development of
integrated urban flood risk management strategies, as they can identify the forcing variables and
infrastructure components that have the most influence upon flood risk.

TL;DR: In this paper, the effects of water transfer through a tunnel from Fatnicko Polje to Bileca Reservoir on the hydrologic regime of the Bregava River located in Eastern Herzegovina, in an area characterised by a predominantly karstic terrain, are studied.
