Title: The accuracy of precipitation measurement in windy conditions and its role in the assessment of flood risk in urban areas 

Proposers: Arianna Cauteruccio , Luca G. Lanza.

Curriculum: Risk and Resilience Engineering for the Natural, Industrialized and Built Environments

Description:  Flood risk assessment and mitigation in urban areas relies on the accurate quantification of the flood hazard, deriving from the knowledge and understanding of the space-time evolution of intense precipitation events. This is obtained from measurements based on in-situ instruments and remote sensors. While traditional catching-type instruments measure the integral properties of rainfall (i.e., rainfall intensity and cumulative rainfall), more recently developed non-catching instruments (including disdrometers) can also measure the microphysical properties of rainfall including the drop size distribution (DSD). The research aims to fill knowledge gaps in precipitation measurements and their use in flood risk assessment. It focuses on assessing the accuracy of disdrometer measurements with respect to wind effects and instrumental biases and developing a suitable disdrometer correction method (DCM).  Results will assess the impact of using corrected rainfall intensity and DSD data on estimating measurement biases due to environmental conditions, evaluating weather radar estimates, improving statistical analysis of rainfall time series at climatological scales, investigating joint rain/wind climatology features at selected test sites, deriving extreme rainfall event statistics and trends aimed at enhancing the resilience of the urban environment to the risk of flooding.

Title: Fragility analysis of roof structures in low-rise buildings subjected to non-synoptic outflows

Proposers: Luisa Pagnini, Giuseppe Piccardo and Maria Pia Repetto 

Curriculum: Risk and Resilience Engineering for the Natural, Industrialized and Built Environments

Description:  Recent catastrophic events in Italy and Europe have highlighted the vulnerability of roof structures to extreme wind induced uplift, often resulting in large economic losses and disruption for those assets. The most destructive events are frequently associated to non-synoptic winds, such as tornadoes and downbursts. The present proposal is addressed to investigate the vulnerability of roof structures to extreme wind actions by means of fragility curves. Fragility curves are extensively adopted in seismic field (e.g. [1]). The same procedure can be reformulated to consider wind loadings and its inherent random nature in speed and direction (e.g. [2]). Specifically, the transient aerodynamic effects caused by downburst accelerated flows will be analyzed through experimental tests in the Giovanni Solari Wind Tunnel, using an innovative active grid capable of replicating the main characteristics of non-synoptic outflows. The results of the proposed project, combined with hazard characterization, will facilitate the study of risk analysis of existing buildings and historical heritage sites against downburst extreme events. Moreover, it will be helpful for determining retrofit options to strengthen existing buildings against this type of extreme meteorological phenomena.

Title: Participatory Approach to Planning Urban Resilience to Climate Change

Proposers: Francesca Pirlone, Anna Palla, Fabrizio Bracco

Curriculum: Risk and Resilience Engineering for the Natural, Industrialized and Built Environments

Description:  

The planning of urban resilience to climate change is addressed with particular attention to the pluvial flooding risk. The adoption of the methodologies typical of participatory processes capable of involving different stakeholders with different techniques (quantitative and qualitative), both in person and online are here foreseen in order to define effective strategies at the levels. The main objective of the present research is to develop a participatory/experiential georeferenced mapping (in GIS) for the planning of urban resilience to climate change. The participatory/experiential georeferenced mapping will be implemented in the city of Genoa for specific case study areas. This research stands out for the important inter-disciplinarity approach of the methodology and subsequent application; the involved interdisciplinary sectors (represented by proposers) are: urban planning, hydrology, and psychology/training science.

Title: 3D-printed artificial rocks for coastal ecosystem restoration

Proposers: Antonio Caggiano (DICCA) and Valentina Asnagni (DISTAV)

Curriculum: Risk and Resilience Engineering for the Natural, Industrialized and Built Environments

Description:  This PhD offer aims to develop 3D-printed artificial rocks using sustainable, cement-based materials and/or geopolymers to restore coastal ecosystems. Coastal regions (i.e., those of Ligurian region) are vulnerable to erosion, habitat degradation, climatic change, extreme weather events and rising sea levels. By designing environmental-friendly artificial rocks that mimic natural formations, this PhD offer can be dedicated to creating durable structures that support the growth of ecologically relevant macroalgae, contributing to ecosystem restoration and enhancing marine biodiversity and ecosystem services provided to human populations.

The project focuses on "green concrete" technologies, emphasizing sustainable materials like geopolymers, which exhibit lower carbon footprints than traditional concrete. At the same time, alternative binders can offer a lower alkalinity in comparison to very high pH values of Portland-based concrete, which range from 13 to 14. 3D printing enables precise control over rock geometry, allowing us to optimize fracture mechanics properties and underwater fatigue resistance to ensure the structures stand for harsh marine environments. By fostering macroalgae colonization, these artificial rocks also contribute to carbon sequestration and the overall health of coastal ecosystems.

Key areas of study will include chemical (ph, composition, TGA, SEM) and mechanical characterization (fracture and fatigue behavior) of the 3D-printed materials under submerged conditions and their interaction with marine flora and fauna. The project will pull forward the capabilities of 3D printing of artificial designs to enhance both mechanical resilience and ecological function of coastal ecosystem restoration.
