O presente relatório descreve de forma sucinta a atividade desenvolvida no âmbito do projeto DAMFA - Soluções de ponta para a avaliação sustentável das fundações de barragens de betão, até ao final de 2017.

The presence of emerging contaminants (ECs) in drinking water and treated wastewaters is a recent raising concern in water and wastewater treatment plants (WTPs and WWTPs), as some compounds were already implied in risk cancer increase, bacterial resistance to antibiotics and reproductive abnormalities in aquatic organisms.The control of ECs in WTPs and WWTPs is therefore a priority that requires the assessment of the risks involved, the improvement of the current barriers and, if necessary, their rehabilitation with advanced treatment technologies. Activated carbon-based technologies have been considered one of the best available solutions for they minimize the by-products formation, but their sustainability and cost-efficiency still calls for activated carbon development and process optimization.To overcome the exhisting challenges for activated carbon full-scale application and upgrade WTPs/WWTPs for ECs control our research group is working with several environmental applications of activated carbon based technologies, per se or coupled with biodegradation and membrane processes. This communication presents examples of applications and main achievements.

No legal requirements have been set for pharmaceutical compounds (PhCs) discharge into surface water bodies; however, changes in legislation may arise as a result of their monitoring in the water bodies (e.g. through the watch list of the environmental quality standards directive) and sound cause-effect (e.g. risk cancer increase or reproductive abnormalities) studies. The largest input source of PhCs into the aquatic environment is through wastewater treatment plants (WWTPs) and, since many of such compounds are resistant to conventional treatment, it is important to anticipate solutions for improving the performance of those infrastructures as crucial barriers for controlling PhCs, and ultimately for the preservation of drinking water sources and the development of safe water reuse projects. The development of technology safety credits towards PhCs control is essential for assisting risk assessment studies, key tools for effective safe water reuse programs. In this perspective, our team has been developing two approaches for controlling PhCs in reclaimed water, on one hand the enhancement of conventional treatment and, on the other hand, the use of advanced wastewater treatment, presenting in this communication one case study for each. Case study I (LIFE Impetus project) focuses the chemical enhancement of conventional activated sludge (CAS) treatment through the addition of commercial and local vegetal waste-based tailored powdered activated carbons (PACs). Case study II (LIFE aWARE project) focuses a PAC/loose nanofiltration (PAC/NF) process for advanced treatment of a membrane bioreactor (MBR) effluent from a Spanish WWTP plant.In case study I, lab adsorption studies and modeling allowed calibrating predictive models of the PAC adsorption capacity and rate. Results anticipate that the addition of 6 mg/L PAC to a well-mixed bioreactor with 12 h of contact time is able to remove 80% of target PhCs. A long-term pilot-scale demonstration with PAC addition to activated sludge systems is on-going in two Portuguese WWTPs.In case study II, two PAC/NF lab configurations were selected and tested at lab scale: i) one with a single PAC dose at the beginning of the filtration cycle (pulse dosing) and ii) another with continuous PAC dosing. No pressure increase was observed during the filtration cycles and high removals of the target PhCs were observed, with 58-89% for the continuous dosing of 50 mg/L PAC. The results were successfully used in the design and operation of the PAC/NF pilot for the technology demonstration in El Prat WWTP (Spain).

As some of these compounds are resistant to conventional wastewater treatment plants (WWTPs) though prone to adsorption, the addition of powdered activated carbon (PAC) emerges as a low capital cost and efficient complementary barrier against PhCs in the treated water. This paper reports the potential application of a newly developed waste-derived PAC for PhC removal in conventional activated sludge WWTPs, during the secondary treatment. The results obtained show that a dose of 6 mg/L of PAC will assure > 80% removal of the three PhCs tested (diclofenac, carbamazepine and sulfamethoxazole).

Neste sentido tem-se vindo a desenvolver a técnica de deteção de dano através de ensaios de caracterização dinâmica ambientais, realizados in situ sem restrições ao funcionamento das obras.Nesta comunicação apresenta-se a aplicação dessa técnica de ensaios na ponte antiga de Foz do Dão, atualmente desativada. A ponte apresenta danos evidentes nos seus elementos estruturais, em parte resultantes de reações expansivas no betão. Foram efetuados ensaios de caracterização dinâmica durante os últimos anos, permitindo um acompanhamento da evolução do seu estado de conservação geral e dos efeitos desses danos no comportamento estrutural global. Na análise da evolução das características dinâmicas tiveram-se em consideração os efeitos das condições ambientais e operacionais.

A challenge in wastewater treatment and water reuse relates to the presence of micropollutants in raw water, the latter often related with pharmaceutical compounds (PhCs). Although WWTPs are crucial barriers against PhCs, many of these compounds are resistant to conventional treatments, thus cost-effective and resource efficient solutions based on existing infrastructure are essential.LIFE Impetus project (LIFE14 ENV/PT/000739) aims at demonstrating feasible measures for improving the control of PhCs in urban wastewater treatment plants (WWTPs) with conventional activated sludge (CAS) treatment. Namely, strategies based on chemically enhanced barriers, with adsorbent and/or coagulant addition, are underway. New powdered activated carbons (PACs) are being developed from industrial wastes available in Portugal (cork, carob processing residues and pinion shell) by chemical and steam activation. The novel biomass-derived PACs (apparent surface areas > 1000 m2/g) are being benchmarked against commercial counterparts.Selected lab-made PACs were already used in laboratory tests assessing the competitive adsorption of a short-list of representative PhCs (diclofenac - DCF, carbamazepine - CBZ and sulfamethoxazole - SMX). Adsorption studies were conducted in synthetic inorganic matrix and in real wastewater effluents from one of the CAS-WWTPs selected as case study. For the carob-derived PAC, 10 to 20 mg/L are needed to attain, in 5 h of contact time, 80% removal of the target PhCs in the mixed liquor of that WWTP.

Technical standardization can play an important role in eliminatingtechnical barriers to the circulation and trade of products and services by unifyingprocedures and criteria. Standardization is a framework of agreements aiming that theprocesses associated with the creation of a product or the performance of a service areaccomplished within a set of guidelines. Its goal is to voluntary define the level ofquality safety that should be recognized and approved in a given field.The European standard EN 16941-1:2018 "On-site non-potable water systems - Part 1:Systems for the use of rainwater", published in January 2018, can help to buildconfidence in the quality and safety of rainwater harvesting. This standard specifies therequirements and gives recommendations for the design, sizing, installation,identification, commissioning and maintenance of rainwater harvesting systems for theuse of rainwater on-site as non-potable water. The rainwater harvesting systems aredescribed through four main functional elements: collection, treatment, storage, anddistribution.

This work presents a reliability analysis, using the response surface method (RSM), for the case study of the left bank excavation slopes of the Baihetan arch dam foundation, which is one of the case studies of Margarida Espada's PhD thesis. The aim was to approximate an implicit limit state function by computing safety factors, using a discrete element model of the Baihetan left bank developed in 3DEC software, where the shear strength parameters of two important rock discontinuities were considered as random variables. The probability of failure was then obtained through an iterativeprocess, using approximation methods. This work presents the 3DEC model developed to analyse thestability conditions in the Baihetan left bank and the results of the reliability analysis.

A three-dimensional finite element model was developed to simulate the biaxial test on the overcored rock specimen and to compute the strains at the location of the strain gauges. Different optimisation algorithms were tested and the most suitable one was selected. The back analysis procedure was tested for identification of the five elastic parameters and the two orientation angles that characterise a transversely isotropic rock core. In spite that, with the developed methodology, convergence was reached and all those parameters could be identified, sensitivity analyses demonstrated that the results obtained were not stable and therefore they were not reliable. By introducing constrains based on common practice and previous experience, a stable and robust methodology was achieved: the three elastic parameters, E1, E2 and Transversely isotropic rock; Numerical method; Rock test; Optimisation; Triaxial strain probe; In situ stress; Overcoring; Biaxial test Espada, M.; Lamas, L.

However, in a temperateclimate, passive ventilation and cooling techniques can reduce energy consumption when the outdoortemperatures are favourable, e.g., at night. Nevertheless, decorative components like the suspended ceiling (SC)contribute to insulation, preventing the desired thermal exchange with the slab. This work investigates an innovativesolution to the optimization of the night cooling phenomenon by using a SC with a peripheral gap andtaking advantage of the plenum formed by the space between the slab and the SC for cooling purposes. Theexperiments were carried out on a reduced scale model. It was found that a SC with a gap allows part of the heatdissipated in the room during the occupation period to be used to heat the slab, thus reducing the air temperatureduring the day, in comparison with a conventional SC with no gap. Moreover, a SC with a gap, and withsupply and extraction slots placed above it, improves the air cooling during the night, and reduces the temperaturesin the occupation zone during the following day, in comparison with a conventional SC with no gap,and with the ventilation slots located below it.

Relations between the EU and China have developed rapidly since the first diplomatic ties were established in 1975. Since 1998, EU-China summits have been held almost every year. The creation of the EU-China Comprehensive Strategic partnership in 2003 has deepened and broadened collaboration in a wide range of areas. The EU-China 2020 Strategic Agenda for cooperation, jointly signed and adopted in 2013, provides strategic guidance for the relations between these two regions of the world on many topics, including science, technology and innovation.In fact, both the EU and China need to foster science, technology and innovation (STI) development to address the economic, social and sustainability challenges they encounter. Interactions between the two regions have also been growing across themes such as environment, energy, climate issues and many others.Within the field of environment, water is a priority for the cooperation with China. An EU-China water platform (CEWP) was established in 2012 to promote policy dialogue, joint research and business development in the water sector.The European partners of the PIANO project (Policies, Innovation, And Network for enhancing Opportunities for China-Europe water cooperation) have worked on the development of this Strategic Research and Innovation Agenda (SRIA) in close cooperation with the representatives of the Chinese institutions, who signed a letter of intent to be involved in the project activities at the time the proposal was presented to the European Commission for its funding by the programme Horizon 2020. Then, in 2015, the EU-China Research and Innovation Co-funding mechanism was not yet in place and Chinese researchers could not be proper partners in the PIANO project activities. Nevertheless, they have provided a very relevant and effective contribution to this SRIA.This Strategic Research and Innovation Agenda is conceived to be a forward-looking document that sets out the direction of future collaborative EU-China research and innovation activities in the water sector, with a special attention to the thematic areas identified and focused on by the PIANO project. This document builds on strategic agendas of European and international actors in water management and internal and external consultations among experts and relevant stakeholders of both areas of cooperation.The PIANO SRIA aims to support the activities of the China-Europe Water Platform in its research pillar being the reference document for the implementation of further initiatives of joint international cooperation between Europe and China in water innovation, a sector which offers increasing opportunities to all interested actors, in particular European small and medium enterprises (SMEs) able to produce advanced technological solutions.This SRIA identifies needs and priorities in the EU-China cooperation in water innovation. It also highlights the main opportunities for the development of further collaborative actions engaging public and private partnerships based on the sharing of knowledge and good practices. In this way, strategic long-term agreements involving multi-stakeholders in research and innovation applied to water management will be fostered. Researchers, governmental agencies, innovative enterprises and private stakeholders should combine synergies to strengthen innovation capacity and promote social and economic cooperation in both regions of the world.Moreover, the PIANO SRIA intends to contribute to the achievement of the United Nations

The present report summarizes the 4th field campaign of the project UBEST, performed in the Tagus estuary on May 10, 2018. This campaign was the first in the Tagus estuary and was representative of spring conditions. Seven stations were chosen along the estuary where in situ measurements of temperature, salinity, pH and dissolved oxygen (% and mg/L) were carried out and water samples were collected to determine in laboratory the concentration of nutrients, chlorophyll a, total suspended solids, and confirm dissolved oxygen and pH on samples where pH sensors were not available. The data acquired will contribute to better understanding the biogeochemical functioning of the Tagus estuary and to calibrate and validate numerical models (hydrodynamic and biogeochemical), that will attempt to predict the response of the estuary to future scenarios of climate change and anthropogenic inputs.

In situ measurements of temperature, salinity, pH and dissolved oxygen (% and mg/L) were carried out and water samples were collected to determine in laboratory the concentration of nutrients, chlorophyll a, total suspended solids, and confirm dissolved oxygen and pH on samples where pH sensors were not available. The data acquired will contribute to a better understanding of the biogeochemical functioning of the Tagus estuary and to calibrate and validate numerical models (hydrodynamic and biogeochemical), that will attempt to predict the response of the estuary to future scenarios of climate change and anthropogenic inputs.
