Abstract. Water shortages are a chronic and severe problem in South Africa. Allocation of this limited water resources, environmental quality, and policies for sustainable water use are issues of increasing concern that require accurate and timely information to evolve strategies for dynamic natural resources management. Specifically, this paper is aimed to assist the planning, restoring and to rationally allocate the water resources in any river basin in resolving the current water stresses in many parts of South Africa, by using integrated knowledge from simulation and integrated river basin management approach. The developed system dynamic (SD) allocation system was used to investigates the extent to which the framework is ‘sustainable’ in the medium and long terms in evaluating existing and future water allocation among conflicting users at Mkomazi River Basin (MRB), KwaZulu-Natal Province, South Africa The invented SD framework confirms agricultural water use as the highest demand when compared with other users. The optimal sustainability performance index (0.25) of the system at 70% dependable flow shows an integrated scenario that combines rainfall variation with improved irrigation water use efficiency as a suitable framework plan. The study uses integrated knowledge from simulation and integrated river basin management approach as a feasible method to assist the planning, restoring and to rationally allocate the water resources in any river basin with similar attributes to the study area in resolving the current water stresses in many parts of the country. Water resources managers would find these tools beneficial in understanding the complex nature of water resources allocation and in determining priorities area which required prompt attention and intervention.

Abstract. The research presents the results of the non-invasive survey campaign conducted at the archaeological site of the city of Verghina in Macedonia. Through the consolidated processes of the disciplines of representation, such as digital surveying, point cloud, flat surface processing, 3D modeling and multi-resolution visualization, it is proposed a path of knowledge of the city and the finds that are the subject of the research. Of great interest is the operational process illustrated both on the basis of the problems that emerged and the solutions adopted in the survey phases. As part of the study, the structures present in the city of Verghina and in the natural area known as the Great Mound, where the Royal Tombs are located, were investigated. The hill of land 13 meters high and 110 meters wide preserves the remains of the ancient city buried in the second century BC to escape the pillage of enemy armies. The research has dealt with the three structures present, namely the Tomb of Philip II, the Tomb of Alexander IV (son of Alexander the Great) and the Tomb of Persephors. The investigations conducted aim to document the current state of the places through digital surveys and parametric modelling, proposing, in addition, the visualization of 3D images through multi-resolution systems derived from the bases of the survey previously carried out.

Abstract. Over the last few years, the world has seen many social, industrial, and technological revolutions. The latter has enabled a combination of expertise from different fields in order to manage a wide range of multidimensional issues such as integrated societies and industrial ecosystems achievement, urban planning, transport management, sustainable development and environmental protection and currently pandemics management. Super smart society's vision that is driving the 5.0 social revolutions is at the heart of the current situation that requires system resilience, sustainability, proactivity, interoperability and collaborative intelligence between society, economy, and industry. Establishing communication bridges between different entities, of different natures and with different objectives implies solutions that reinforce the development of efficient, dynamic, and communicating business models on a large scale, merging cyber and physical spaces. Through this paper we explored the potential of digital twins for the development of a new vision of world global dynamics under the aegis of a virus whose parameters are still elusive to date.

Abstract. Great effort has been recently employed for the development of a modern and competitive agriculture in Morocco, growth in the agricultural sector is determined largely through the realization of thousands of new projects, and the support of the smallholder farmers at a national scale. Modernization of irrigation systems, and enlargement of the extent and spatial distribution of irrigated areas holds the key to increase annual productions. In this context, we established a unique procedure for monitoring the agricultural surfaces not fully exploited in terms of potential and production, in the semi-arid zone of the Haouz plain, central Morocco. We derived Normalized Difference Vegetation Index (NDVI) time series from Sentinel-2 (S2) and Landsat 8 (L8) high spatial resolution satellite images from 2016 to 2018. Seasonal phenological changes and land-cover dynamics, in addition to elevation models and landscape slopes, helped determine periods and thresholds suitable for classes separability, and establish a set of rules to be implemented in a Decision tree classifier model for a detailed land-cover mapping of the last three years. The agricultural zone was successfully separated from mountains and hills, and the derived maps of the three years yielded satisfying result with an OAthat reached above 91% for quite detailed landscape-type information. The outputs of this work hold promise to provide valuable information for planners, decision-makers and regional offices, to help smallholder farmers. Although this approach has been developed at regional-scale, it holds the potential to be adapted to larger scales, with the appropriate selection of land-cover types, and carful adjustment in the threshold values.

Abstract. Nowadays, cities need sustainable approaches that take care of the future in order to meet the needs that arise with population activity. Accordingly, for making cities more livable, the necessity of ensuring efficient use of urban sources and planning urban infrastructures brings the smart city concept into the forefront. The smart city solutions are frequently applied by many local governments and stakeholders. For this reason, there is a need to support the collaboration of all relevant actors and to provide a common national strategic perspective among smart city stakeholders. In the Strategic Plan of the Ministry of Environment and Urbanization, the objectives of smart cities and national geographic information services are determined as “to make infrastructure works in order to establish smart cities, to improve the spatial management in cities with the help of technology, to share data to improve public services and to be the focus of national geographical information” and studies on these objectives have been completed. Accordingly, the “2020–2023 National Smart Cities Strategy and Action Plan” has been prepared in order to establish a national strategic view on smart cities and draw a road map under the policy ownership of the Ministry of Environment and Urbanization. By the implementation of this strategy and action plan with the vision of "Livable and Sustainable Cities that Add Value to Life", a new process of transformation and change will be provided to cities that take care of the real needs of citizens, adopting participatory governance by using resources effectively.

Abstract. Servers are systems that set up to run for years, but it may be necessary to migrate to a new, better server when they have completed their lifetime or become inadequate. In this study, the open-source iRedMail e-mail server has been successfully migrated to another high-capacity physical server which uses an open-source CentOS operation system. Migration is a process that every step has to be very well planned. However, although planning is well done, unexpected errors may occur. For this reason, it is also essential to choose migration time. The experience gained as a result of the study is a guide for the new ones.

Abstract. The Vehicular Ad-hoc Network (VANET) is a fast-growing and highly motivated area of research to provide Intelligent Transport Systems (ITS) services to end-users; these services are also responsible for providing an efficient driving environment. in VANET networks, several routing protocols have been designed, but still networks are vulnerable to many threats in the presence of malicious nodes. Today, security is a major challenge in various VANET applications where a bad message can directly or indirectly affect human lives. In this paper, we examine some routing attacks such as Black hole & Wormhole attacks, as well as available solutions for such attacks in existing VANET protocols.

Abstract. “Earthquakes” may cause dangerous results for people, which can damage buildings and hurt people, and may even cause death. Turkey lays down in a highly earthquake-prone region. Earthquakes are unpredictable and uncontrollable natural events; however, the people have to find ways to reduce these damages on people. One of the ways is to build “earthquake-resistant buildings”. It is also one of the main necessities to build smart city under the focus of housing quality, quality of life. In this paper Building Control System in Turkey is presented in the frame of the legal basis in a general view. Also surveying documents related to building control system are introduced because land surveying studies are compulsory-preliminary works before building construction.

Abstract. This study aims to investigate the possibility to automate the image selection process for the target building from Mapillary images through a web application where the user only initiates one image of the target building as a query. Using the data provided with Mapillary API and Overpass API, all images having full or partial coverage of the target building were selected. Then the images were segmented by using a pre-trained U-Net model to discard any images having less than 20% building coverage. The experiments showed promising results yielding 0.971 and 0.887 of overall accuracy after segmentation steps for two different target buildings.

Abstract. The adoption of an ecological sanitation system, meeting the requirements hygienic and sanitary, constitutes a feasible and technically and economically acceptable solution in the future smart city. This new sanitation concept has the advantage of solving the problems of pathogens of human waste at source, thus offering the possibility of reusing them after treatment (recycling) in order to improve the standard of living of the population and protect the environment. The aim of this study is to evaluate the efficiency of a vertical Multi-Soil-Layering system (MSL) system to treat domestic wastewater under three hydraulic loading rates: 250 L/m2/day, 350 L/m2/day and 500 L/m2/day, in Moroccan conditions. To do this, a vertical MSL system measuring 20cm × 60cm × 78cm (L × W × H) was designed to treat domestic wastewater and his performance was investigated. The results showed high removal of organic matters and nutrients under the three hydraulic loads tested; the performance averages recorded are upper than 84 % for organic matters, 83.1 ± 7.2 % for ammonium and 72.4 ± 14.1 % for orthophosphate. The quality of the treated wastewater was evaluated according to Moroccan reject limit value. Consequently, this system could be considered an effective solution to be adopted for decentralized domestic wastewater treatment in Moroccan conditions.

The adoption of an ecological sanitation system, meeting the requirements hygienic and sanitary, constitutes a feasible and technically and economically acceptable solution in the future smart city. This new sanitation concept has the advantage of solving the problems of pathogens of human waste at source, thus offering the possibility of reusing them after treatment (recycling) in order to improve the standard of living of the population and protect the environment. The aim of this study is to evaluate the efficiency of a vertical Multi-Soil-Layering system (MSL) system to treat domestic wastewater under three hydraulic loading rates: 250 L/m2/day, 350 L/m2/day and 500 L/m2/day, in Moroccan conditions. To do this, a vertical MSL system measuring 20cm × 60cm × 78cm (L × W × H) was designed to treat domestic wastewater and his performance was investigated. The results showed high removal of organic matters and nutrients under the three hydraulic loads tested; the performance averages recorded are upper than 84 % for organic matters, 83.1 ± 7.2 % for ammonium and 72.4 ± 14.1 % for orthophosphate. The quality of the treated wastewater was evaluated according to Moroccan reject limit value. Consequently, this system could be considered an effective solution to be adopted for decentralized domestic wastewater treatment in Moroccan conditions.","PeriodicalId":14757,"journal":{"name":"ISPRS - International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences","volume":"11 4 1","pages":"391-398"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84927902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
