In this context, porous concrete paving represents a sustainable alternative, as it controls rainwater runoff and has a high albedo, a property that quantifies the amount of light reflected by the surface. Clogging is a phenomenon that involves the obstruction of the pores of the porous concrete, which occurs due to the entry of sediments and leads to the loss of the useful path of the porous concrete flooring. Therefore, this study aims to analyze the effects of clogging on porous concrete pavements, focusing on thermal behavior, thermal conductivity and evaporative process. Initially, the influence of air temperature and relative humidity on the surface temperatures of porous concrete pavements in the clean state was analysed, in which a significant sensitivity to environmental conditions was observed, highlighting the importance of these factors. Comparing clean and clogged sidewalks, it was found that while clean sidewalks had slightly higher surface temperatures during sun exposure, clogged sidewalks cooled faster. Thermal conductivity analysis highlighted a discrepancy between floors in a clean and clogged state, highlighting the influence of clogging on the heat capacity of the material. The presence of sand as a sealing material reduced the void content, increasing thermal conductivity, which is directly related to heating and heat dissipation. In the evaporation test, the clogged plates showed a slightly higher evaporated mass than the clean plates, this increase in evaporated mass was attributed to the clogged sand's ability to retain water between its voids. Therefore, the results suggest that clogging brought better results than pavement in the clean state in terms of thermal and evaporative performance.

However, the implementation of these structures depends on an adequate assessment of the geotechnical behavior of marine soils, especially carbonatic sandy soils present on the Ceará Continental Shelf (CCS), which exhibit mechanical characteristics distinct from those of conventional quartz sands. In this context, this study aims to analyze the performance of offshore monopile foundations installed in carbonatic sandy soils along the Ceará coastline through three-dimensional numerical simulations. Initially, two carbonatic sands representative of the region were considered and characterized based on drained triaxial compression (CD) tests, whose results served as the basis for calibrating the constitutive parameters. The back-analysis of these tests was carried out using the PLAXIS 2D software, adopting the Hardening Soil (HS) constitutive model in order to adequately reproduce the stress-strain behavior of the soils. Subsequently, three-dimensional models were developed in PLAXIS 3D to simulate the soil–structure interaction of different monopile geometric configurations subjected to monotonic loading. The results allowed the evaluation of the influence of soil density state, embedment length, and L/D ratio on the lateral load-displacement behavior of the foundations. Finally, the performance of the monopiles was assessed according to the applicable normative criteria, considering both Serviceability and Ultimate Limit States. The results indicate that the carbonatic sands of the Ceará coastline show potential for the installation of offshore monopile foundations, provided that the geotechnical particularities of these soils are properly considered in the design process.

In this context, this study evaluates the stability of unsaturated granular slopes of an earth dam located in the Brazilian semi-arid region, considering the influence of climatic actions and reservoir water level fluctuations over time. The case study was developed using real data from a representative earth dam, with analyses performed for distinct hydrological years selected based on differences in rainfall regimes. The methodology was based on transient numerical modeling using the GeoStudio software package, with integrated application of the SEEP/W and SLOPE/W modules, enabling coupled simulation of unsaturated flow and slope stability. Hydraulic and mechanical parameters of unsaturated granular soils were adopted, including the soil–water characteristic curve, suction-dependent permeability, and shear strength parameters incorporating the effect of matric suction. The results show that the safety factor varies significantly over time, following reservoir water level oscillations and the hydraulic response of the embankment to rainfall events. A reduction in the safety factor was observed during periods of intense precipitation, associated with suction reduction and increased pore-water pressures, highlighting the importance of transient analyses for safety assessment. It is concluded that explicitly considering climatic conditions and unsaturated soil behavior is essential for a more realistic evaluation of earth dam stability in semi-arid regions.

This aspect of engineering is often subject to subjectivity regarding numbers, as it includes values ​​that are often not objectively measured numerically. Therefore, this work seeks to evaluate the real value of properties and conduct a comparative analysis between two cities belonging to the Metropolitan Region of Fortaleza: Maracanaú and Eusébio, based on the price per square meter of each and their respective investigations. In order to guarantee a better result in this valuation process, the most current information in the field of property valuation will always be verified, in addition to being in contact with professionals who do this in their daily work. Therefore, by conducting research in bibliographic references, standards, and with professionals, the goal was always to fulfill all the requirements of an evaluation that would bring accurate results so that the necessary guidance could be drawn and a parallel as close as possible to reality could be established.
