The present report summarizes the field campaigns of the project MOSAIC.pt, performed between January and March 2019 in the Cova-Gala, Vieira and São Pedro de Moel beaches, located in the Portuguese west coast. The campaigns aimed to characterize the response of the beaches, with diverse typology, to the hydrodynamic forcing and included topographic surveys by GNSS-RTK, drone surveys, superficial sediment sampling and the report of the territorial elements affected.

This report stands for the PROPER project deliverable 1.3 and concerns the results from task 1.3: Roadrunoff monitoring data and representative sites.Following the literature review and the evaluation of the models conducted in previous tasks from WP1,the aim of the present task is to gather road runoff monitoring data from representative sites acrossEurope. The data will be used in task 1.4 of the project to assess the consistency and suitability ofselected tools to predict road runoff characteristics.In order to accomplish the task objectives, the data should comprise the requirement inputs that areneeded to implement the tools such as the characteristics of the road and of the traffic, climate featuresand monitoring data from precipitation and runoff events.A total of 22 case studies were gathered from 7 different countries, namely Norway, England,Switzerland, France, the Netherlands and Portugal. The roads and the monitored pollutants arecharacterized in the present report.For the purpose of this project and the planned following activities, the objectives were achieved, and aset of roads with wide range and diverse characteristics was gathered.

A 3rd edition of the Replicability and Transferability Plan was produced, building on the 2018 and 2016 editions. This plan defines a strategy for the valorisation of the results.

This document reports the communication, dissemination and development activities of LIFE Impetus project for the 3 years that follow the date of completion of the project.

This document presents relevant indicators that may affect the impact of LIFE IMPETUS project actions, as well the results of a Future Scenarios Design exercise, in order to address a sustained approach to their potential.

The main objective of this work is the development and presentation of a three-dimensional finite element program, DamSlide3D, to study the behavior of gravity dams for scenarios of sliding through the dam-foundation interface. The DamSlide3D, developed using MATLAB, includes cube-type finite elements with 20 nodal points ("serendipity") and finite interface elements with 16 nodal points (joint elements). Initially, we present the fundamental equations of Solid Mechanics, referring to the main simplified hypotheses considered in the computationally implemented formulation, which is presented mathematically as a problem of boundary values using a displacement formulation. For the structure body and for the foundation, the hypothesis of isotropic materials with linear elastic behavior is assumed and for the interfaces the hypothesis of non-linear behavior is considered using the Mohr- Coulomb criterion. The DamSlide3D input data is provided in an excel file and includes structure geometry data, material properties, support conditions and load parameters. As output, the program graphically displays the stress field (principal stresses) and the displacement field (deformed structure). The program was verified throughout three numerical tests with known theoretical solutions. In these tests a simple structure was used, composed by a column discretized in 3DFE. At the contact surface between the column and the base (horizontal surface) it was considered an interface discretized using joint finite elements. A plane surface that crosses the column with a given slope is also considered, discretized using the same type of joint finite elements. In the first test, the field of elastic stresses at the base, due to self-weight (SW) and hydrostatic pressure (HP), was compared with the theoretical results. In the second test the nonlinear column response was studied for different values of thefriction angle at the inclined interface (in this test the structure is only submitted to SW). In the third test, for the main SW + HP loads, the stability of the column is studied for a variation of the friction angle, and for a variation of the water level. In these three numerical tests the results were always consistent with the theoretical solutions. Finally, as an example of application, a gravity dam structural behavior was analyzed considering the non-linear behavior in the dam-foundation interface. The dam was subjected to self-weight and hydrostatic pressure. A parametric study was developed in order to study the dam stability for differentvalues of water level and friction angle.

Neste relatório é apresentada a apreciação final do Estudo Prévio das fundações e estruturas da plataforma e reforço complementar do Terminal Fluvial sul e sueste no que respeita à segurança antissísmica. São avaliados os aspetos relacionados com o modelo geotécnico considerado pelos autores do Estudo Prévio, com as metodologias de análise de segurança dos taludes em situações de projeto sísmicas e com as interferências com as infraestruturas do Metropolitano de Lisboa no Terreiro do Paço. É emitido um Parecer de sentido positivo face às soluções de obra baseado nos resultados de análise de desempenho sísmico, condicional à observância de recomendações na elaboração do Projeto de Execução as quais visam a confirmação daqueles resultados, cuja representatividade é naturalmente limitada pela natureza simplificada própria de uma análise em estudo prévio.

The growing concerns about the climate change and the negative environmental impacts of heating andcooling systems operated by fossil fuels, have led the technical and the scientific communities to find out more environmentally and sustainable energy alternatives, such is the case of shallow geothermal sources. Shallow geothermal systems use the ground as a heat reservoir, transferring thermal energy from the ground to a building, or vice-versa, with the help of a heat pump, to provide warmth in winter and cooling in summer. A proper evaluation of the thermal properties of the soil is essential in their design process and for a sustainable system. Thermal conductivity is the most important parameter for this evaluation. Thermal conductivity can be estimated or measured by several methods, namely by means of empirical correlations, and experimentally, either in situ, by means of the well-known Thermal Response Tests (TRT), or in the laboratory, under steady state or transient conditions. This work presents a series of thermal conductivity measurements on dry sand samples obtained by means of a high accuracy system with reference TPSYS02 Hukseflux equipped with Non-Steady-State Probes (NSSP) (TP02 or TP08). The system was acquired in the aim of an FCT research project. The work includes the completion of a guide to procedures to the use of the thermal measurement system. Details of its calibration as well as results from tests in soil samples are also presented.
