This paper presents the performance quantification of different green-grey infrastructures, including rainfall-runoff and infiltration processes, on the overland flow and its connection with a sewer system. The present study suggests three main components to form the structure of the proposed model-based assessment. The first two components provide the optimal number of green infrastructure (GI) practices allocated in an urban catchment and optimal grey infrastructures, such as pipe and storage tank sizing. The third component evaluates selected combined green-grey infrastructures based on rainfall-runoff and infiltration computation in a 2D model domain. This framework was applied in an urban catchment in Dhaka City (Bangladesh) where different green-grey infrastructures were evaluated in relation to flood damage and investment costs. These practices implemented separately have an impact on the reduction of damage and investment costs. However, their combination has been shown to be the best action to follow. Finally, it was proved that including rainfall-runoff and infiltration processes, along with the representation of GI within a 2D model domain, enhances the analysis of the optimal combination of infrastructures, which in turn allows the drainage system to be assessed holistically.

Mitigation Effort

During a flood alert, the decision to evacuate a threatened collection of a library is an important one. If not thought out carefully, a hastily executed move can expose valuable collections to unforeseen threats. Although floods are usually slow to develop in Paris, the decision to make a preventive evacuation must be taken at the appropriate moment, considering the time needed for the relocation, the reality of the threat and the need for service continuity. In the context of its flood protection plan, the National Library of France has conceived a box model that contributes to saving time in case of a flood and prevents damage during an evacuation. Combining accessibility to documents with security requirements, this model can be implemented in different contexts.

The Impact

Abstract. Considering the likely increase of coastal flooding in Small Island Developing States (SIDS), coastal managers at the local and global level have been developing initiatives aimed at implementing Disaster Risk Reduction (DRR) measures and adapting to climate change. Developing science-based adaptation policies requires accurate coastal flood risk (CFR) assessments, which are often subject to the scarcity of sufficiently accurate input data for insular states. We analysed the impact of uncertain inputs on coastal flood damage estimates, considering: (i) significant wave height, (ii) storm surge level and (iii) sea level rise (SLR) contributions to extreme sea levels, as well as the error-driven uncertainty in (iv) bathymetric and (v) topographic datasets, (vi) damage models and (vii) socioeconomic changes. The methodology was tested through a sensitivity analysis using an ensemble of hydrodynamic models (XBeach and SFINCS) coupled with an impact model (Delft-FIAT) for a case study at the islands of São Tomé and Príncipe. Model results indicate that for the current time horizon, depth damage functions (DDF) and digital elevation model (DEM) dominate the overall damage estimation uncertainty. We find that, when introducing climate and socioeconomic uncertainties to the analysis, SLR projections become the most relevant input for the year 2100 (followed by DEM and DDF). In general, the scarcity of reliable input data leads to considerable predictive error in CFR assessments in SIDS. The findings of this research can help to prioritise the allocation of limited resources towards the acquisitions of the most relevant input data for reliable impact estimation.

Legislative Framework

The article deals with state and regional actions taken to eliminate the effects of natural disasters. It focuses on clarifying the causes, extent and impact of flood damage in the years 1997–2010, not only in the Czech Republic but also in neighboring countries within each river basin crossing the border. The legislative framework is given by the European Union´s Directive on the assessment and management of flood risks. The directive is followed by the strategy of flood protection in the Czech Republic according to the specifications of the assets of the state, municipalities, citizens and businesses. Action plans for flood protection are then processed in accordance with individual river basins, the ones discussed in this article being the Elbe, Danube and Odra. A chronological summary of floods during the 1997–2010 period presents relevant data on these events, including comparisons with previous periods. In conclusion, the authors present data on the number of claims, the extent of the damage, and the total sum of insurance claims paid out by member associations of the Czech Insurance Association. It also deals with problems concerning the underestimation of insurance coverage, especially among small and medium-sized businesses.

The City

Extreme flooding events are increasingly common due to climate change and the City of Madison, Wisconsin is uniquely at risk. The City can mitigate further flood damage by encouraging development of green infrastructure. We recommend the City incentivize green infrastructure by creating a small grants program for residential green infrastructure projects, modeled after a successful program in Milwaukee and funded by pairing federal grants with an increase in the water rate structure. The grant program could be supplemented by altering the City’s stormwater fees to shift cost to residents generating the most runoff and by a volunteer program that would engage community members.
