In order to improve the management and to better locate water losses, Water Distribution Networks can be physically divided into District Meter Areas (DMAs), inserting hydraulic devices on proper pipes and thus simplifying the control of water budget and pressure regime. Traditionally, the water network division is based on empirical suggestions and on ‘trial and error’ approaches, checking results step by step through hydraulic simulation, and so making it very difficult to apply such approaches to large networks. Recently, some heuristic procedures, based on graph and network theory, have shown that it is possible to automatically identify optimal solutions in terms of number, shape and dimension of DMAs. In this paper, weighted spectral clustering methods have been used to define the optimal layout of districts in a real water distribution system, taking into account both geometric and hydraulic features, through weighted adjacency matrices. The obtained results confirm the feasibility of the use of spectral clustering to address the arduous problem of water supply network partitioning with an elegant mathematical approach compared to other heuristic procedures proposed in the literature. A comparison between different spectral clustering solutions has been carried out through topological and energy performance indices, in order to identify the optimal water network partitioning procedure.

Sea-level rise (SLR) poses a range of threats to natural and built environments in coastal zones around the world. Assessment of the risks due to exposure and sensitivity of coastal communities to coastal flooding is essential for informed decision-making. Strategies for public understanding and awareness of the tangible effects of climate change are fundamental in developing policy options. A multidisciplinary, multinational team of natural and social scientists from the USA, the UK, and Brazil developed the METROPOLE Project to evaluate how local governments may decide between adaptation options associated with SLR projections. METROPOLE developed a participatory approach in which public actors engage fully in defining the research problem and evaluating outcomes. Using a case study of the city of Santos, in Brazil, METROPOLE developed a method for evaluating risks jointly with the community, comparing ‘no-action’ to ‘adaptation’ scenarios. At the core of the analysis are estimates of economic costs of the impact of floods on urban real estate under SLR projections through 2050 and 2100. Results helped identify broad preferences and orientations in adaptation planning, which the community, including the Santos municipal government, co-developed in a joint effort with natural and social scientists.

Capillary rise is a serious phenomenon that may have potentially devastating consequences within buildings (biological corrosion, worsening of indoor comfort parameters, worsening of thermal resistance, etc.). Therefore, measuring moisture in building structures is still a current research issue and time domain reflectometry (TDR) is considered one of the most-effective nondestructive methods for moisture estimation in porous media. This paper reports a research examining the effects of different kinds of mortar on the capillary rise in yellow volcanic tuff walls. To this aim, three model walls were built with tuff and three different kinds of mortar (a traditional cement lime mortar and two premixed mortars, one of which was specifically designed to prevent capillary rise), and then instrumented with TDR probes, to carry out continuous monitoring of volumetric water content without the need of sampling or material destruction. Preliminarily, the calibration relationship linking relative dielectric permittivity, provided by TDR measurement, with volumetric water content, measured gravimetrically, has been experimentally determined in laboratory with yellow tuff specimens. The obtained results suggest that TDR can be suitable to reliable in situ monitoring of moisture dynamics in tuff walls in a nondestructive way. The velocity and height of capillary rise resulted strongly affected by the adopted type of mortar. In particular, the wall made with simple premixed mortar was characterized by the highest water absorptivity, whereas the one made with the specific antirise mortar showed the lowest moisture increase. The obtained results also allowed a physical interpretation of the behavior of water uptake related to the different types of mortars.
