[CEST2019_00888] Soil erosion as a consequence of climate change
by Hupková D.

The climate change and relevant negative impacts are currently widely discussed topic. The agricultural soil erosion represent the risks generated also by agricultural activities reflected in soil quality. Rapid climate change can cause the instability of most agricultural and forest ecosystems. Climate change is expected to affect the conditions under which agricultural production is done in many ways. In Slovakia, agricultural soils are potentially at risk of water erosion of varying intensity. Wind erosion is not a serious problem in Slovakia in recent years. Despite the fact that soil erosion level shows in Slovakia in recent period a slight decline however the adoption of soil conservation practices are necessary for future sustainability

by Potamianou N., Papadopoulou C.-A., Papadopoulou M.P., Charchousi D.

The future sustainable development constitutes a critical issue at a global scale. It builds upon the concepts of combating poverty & inequality, mitigating climate change impacts as well as protecting natural & cultural resources through innovation & adoption of eco-friendly solutions. It is a human-centric approach that places people at the core of its priorities. Seventeen Sustainable Development Goals (SDGs) have now been set by the United Nations (UN) for the year 2030, each accompanied by a set of indicators measuring their performance. This paper focuses on the contribution of each sustainability indicator to the accomplishment of the respective goals, especially in case of drylands. A general overview of the SDGs & the relative indicators are analyzed. Then, indicators related to climate change impacts are explored following by an assessment of the contribution of these specific indicators to the management of drylands under climate change conditions.

[CEST2019_00605] Coal ash zeolite as a self-catalytic-chemisorption system for conversion of carbon dioxide to hydrocarbons
by Boycheva S., Zgureva D.

In our study, initial attempts on the convertion of carbon dioxide to hydrocarbons based on the catalytic activity and the atmospheric moisture-retaining ability of coal fly ash derived zeolites (FAZ) are provided. The experimental investigations on the CO2 chemisorptions were performed in a static reactor at pressure of 5.5 MPa over FAZ of Na-X type. The conversion of CO2 to hydrocarbons was established by IR-spectroscopic and differential thermal studies. This study outlines new research challenges for the development of technological solutions for the effective reduction of greenhouse gases by converting CO2 into synthetic fuels.

[CEST2019_00573] Thermal Swing Adsorption in a Carbon Capture System
by Zgureva D., Boycheva S., Miteva S., Lazarova H., Marinov I., Popova M.

In the last years, the post-combustion capture of CO2 based on physical adsorption has been extensively studied in terms of economy, ecology, and process efficiency. The industrialization of the process involves the construction of adsorption columns in which adsorption and desorption mass transfer occurs. Each one solid-gas system has individual mass and heat transfer properties. In this study, the adsorption and desorption processes in the fly ash zeolite (FAZ) - CO2 system were investigated in dynamic conditions. The breakthrough curves were built performing series of experimental measurements under varying conditions in order to establish the optimal desorption temperature. Multiple adsorption/desorption studies were performed in the temperature range 50-200 oC at the maximum leakage concentration of 5 vol % CO2 in the exhaust gas stream versus the time. The small variation in the adsorption capacities achieved and the minimal deviation in the break point determine suitability of the FAZ-CO2 system for low thermal swing adsorption process at 50 oC.

[CEST2019_00590] Comparative studies of the equilibrium adsorption of CO2 onto coal ash zeolites Na-X and Na-Ca-X
by Boycheva S., Marinov I., Miteva S., Zgureva D.

Coal-fired Thermal Power Plants (TPPs) are the main source of greenhouse gas emissions in the atmosphere, but they also generate huge amounts of solid by-products, including fly ash (FA). Thanks to its aluminosilicate nature, FA is investigated to be converted into zeolites for applications in gas cleaning systems. The development of technologies for CO2 capture by fly ash zeolites (FAZ) will provide a join solution for the two main ecological problems concerning coal supplied TPPs, namely utilization of solid residues and implementation of carbon capture technologies. In the present study, the comparative studies were performed on the adsorption of CO2 onto FAZ of Na-X and Na-Ca-X types in relation to their specific surface and porosity.

[CEST2019_00568] Heat of Adsorption in the Fly Ash Zeolite – CO2 System at Dynamic Conditions
by Zgureva D., Boycheva S., Marinov I., Miteva S., Asenov A.

Recently, the global warming is one of the major world problems considering that coal-fired power generation accounts for 40 % of the total CO2 emissions. The post-combustion capture of CO2 based on physical adsorption has the greatest potential to meet the industrial needs. The nature of the adsorption processes is complex and is described by many empirical constants that are determined experimentally for individual contact systems.
In this study, the heat of adsorption in the fly ash zeolite (FAZ) – CO2 system was investigated experimentally. The technique used includes online measurements of temperature rise during the exothermic adsorption process carried out by passing CO2 through a laboratory-assembled column filled with FAZ. Based on the experimental results, the calculated specific heat of adsorption amounts to Hads=-36.83 kJ/kg.

[CEST2019_00529] The Influence Of Danube River Hydrographic And Thermic Factors On Fish Stocks Dynamics In Razim-Sinoe Lagoon System
by Chioveanu M.C., Simionov I.A., Patriche N., Tenciu M., Dragomir E., Cristea V., Minzala D.N.

The Romanian fishing areas extends over 7000 km2 and 50% of the numbers of authorized fishers conduct their activities in the Danube areas. Inland fisheries are highly important for income, food security and nutrition. Inland peri-rural fisheries face degradation due to climate change. According to the European Commission, the dominant factor driving the change in water resources in Danube River basin is climate change. Global mean surface temperatures have increased, fact which causes a constant increase in water temperature as well. Razim-Sinoie Lagoon System represents the largest lagoon (1145 km2) in Romania and stands out for its ecological, historical and socioeconomic importance. The lagoon is connected to Danube River through the channels Dranov and Dunăvăț and receives significant river intake. This present study points out the vulnerability of fish stocks and Romanian fisheries in the context of climate change and global warming. Thus, the aim is to evaluate the influence of multiannual hydrographic and thermic regime on fish stocks status and structure from Razim-Sinoe Logoon System, between the years 2016-2018. Thus, a strong positive correlation was observed between the water temperature and the total quantity of fish catches. In case of fish stocks, a simultaneous decline of ichthyophagous fish species, while increasing the stocks of non- ichthyophagous fish species, is recorded.

[CEST2019_00478] A web-based GIS tool for environmental footprint estimation of agribusinesses
by Hliaoutakis A., Papadopoulos S.N., Kydonakis A., Doula M.K., Papadopoulos N., Sarris A.

The deterioration of environmental quality and vulnerability to climate change of the Balkan Peninsula are escalated by the lack of specific financial and strategic measures that can promote sustainable resource management. Environmental problems of the Balkan countries need to be addressed under a unified context targeting the development of common strategies to improve environmental quality and reach European and international markets. To this end, the INTERREG project “Towards farms with zero carbon-, waste- and water-footprint. Roadmap for sustainable management strategies for Balkan agricultural sector - BalkanROAD” aims to provide Balkan agribusinesses with protocols and Information Technology tools conformed to the particularities of the Balkan Peninsula, in order to promote products of high quality and value to the European and international market. Within the project’s framework, a web-based GIS application tool was developed, the so-called, ROAD, that assesses all production and processing stages, namely from field to the market, capable to identify processes that can be improved and provide alternatives for reducing carbon, waste and water footprint of the final marketable products. In this work we describe the ROAD tool implementation steps, as well as some of its key functionalities.

[CEST2019_00296] The role of sustainability rating systems in delivering infrastructure and building engineering’s contribution to climate change mitigation and adaptation
by Venables R.K.

working on infrastructure and buildings to assess what relevant action they should be taking in their designs and construction. In parallel, scientists working on construction or environment-related topics often need guidance on the key construction areas that need further investigation to assist with the challenges derived from the need for climate change mitigation and adaptation.
Over the last few years, rating systems have been developed for the environmental performance of buildings and infrastructure, and more recently their sustainability performance. Their development has included the formation of assessment questions and criteria that direct designers and constructors towards improved environmental and social performance. Alongside those rating systems, tools such as carbon calculators have also been refined to enable option comparisons.
This paper explores a selection of climate change-related issues assessed in or by such rating systems and tools, and how the nature of assessment questions, scoring systems and measurement tools can drive improved performance. Through that improved performance, design and construction teams can maximise their contribution to climate change mitigation and adaptation, and scientists identify the key areas for further examination.

[CEST2019_00094] An Analysis of the Expected Climate Change Effects in the Vicinity of the Main Harbors from the Black Sea
by Rusu L.

The objective of this work is to analyze the dynamics of the environmental matrix in the context of climate change in the vicinity of the main harbors from the Black Sea. The main environmental parameters considered for analysis are wind and waves. The climatic wind fields provided by the Rossby Centre regional atmospheric model are analyzed until the end of the 21st century, considering the results corresponding to the Representative Concentration Pathway scenario 4.5. These wind fields are used to force a wave modelling system based on the SWAN (Simulating Waves Nearshore) model. In this way, the wind and wave data expected along the entire 21st century in the vicinity of the most important harbors of the Black Sea are provided. From the analysis of these wind and wave data, an enhancement of the extreme wind conditions can be noticed. On the other hand, due to the high variability in the wind direction, the amplitudes of the extreme waves are expected to slightly decrease.

[CEST2019_00120] Reactivation of former watercourses to support urban stormwater management
by Simperler L., Glanzer M., Ertl T., Kretschmer F.

In recent decades many urban water courses have been heavily modified by land gaining measures aiming at canalising, straightening and draining existing water systems. Additionally, urbanisation causes a higher degree of sealing which results in higher surface runoff during rainfall. To support related problem-solving, the presented work investigates the question of whether the reactivation of former water courses could make a positive contribution to urban stormwater management. Based on the case study of an Austrian municipal area the research work follows a two-target approach: First, the collection, digitalisation and verification of the former water courses in the investigated area based on historical maps and recent planning documents. Second, a GIS-based overlap of the verified (still existing but inactive) natural water courses with the current sewage and stormwater network to derive potential options for relieving the strain on the entire urban drainage system. Results show, that reactivation of former water courses can be an interesting and promising component of an integrated and thus more natural urban stormwater management approach.

[CEST2019_00053] Assessment of Concrete Footpath Upheavals in Heatwaves
by Bradford M.

Most concrete footpaths are cast without steel reinforcement and in segments between bituminous joints, with the joints intended to accommodate thermal expansions of the pavement. However, a combination of prolonged heatwave conditions and the ingress over time of material into the joints produces a situation in which the thermal movements are not in the plane of the pavement, but instead the pavement experiences an upheaval buckle. Within a framework of global warming and heatwaves, assessments of the potential for such buckles which pose a risk to safety are essential. This paper presents a solution in closed form for the combination of key parameters at buckling needed to undertake such an assessment.
