Monitoring of Buituri Slag Dump, Hunedoara County in Relation with Environmental Protection

Detailed analysis of appearance and relief evolution in mining areas cannot be done without mining engineering concepts. Over time, researchers around the world have responsibly been involved in this matter necessary for the development of society, also with obvious implications and repercussions over the quality of life. The purpose of the scientific research detailed in this paper comprises in monitoring the slag dump from Buituri, Hunedoara County using space geodetic technology. Slag dump is the result of steel production activities carried out under the steel factory Arcelor Mittal Hunedoara S.A., formerly known as the steel factory Hunedoara - Siderurgica S.A. Therefore it was decided to conduct monthly topographic measurements to monitor possible dynamic changes that may appear in the context of continuous exploitation of the above mentioned slag dump. Monitoring possible movements is performed by comparing transversal and longitudinal profiles drawn based on zero measurement carried out on 20.05.2011, with the ones obtained after processing of the monthly measurements realized throughout the years 2011, 2012, 2013, 2014, 2015 and 2016. Also, for observing the displacements, comparative charts or tables with records regarding coordinates differences are studied. The issue of measuring and graphic representation of settlements, horizontal linear movements and landslides for structures such as slag or sterile dumps, requires further studies and interdisciplinary research, creating links between specialists in the fields of terrestrial measurements science and geology

WebGIS Solution for Urban Planning Strategies

AbstractIn line with the objectives established by the “European capital of culture” initiative, the entire community is involved in embarking socio-economic and infrastructure projects supported by an information platform which ensures efficient data management for the municipality. This platform should provide a good visibility of the candidate city in the context of enhancing the contribution of culture to its long-term development in accordance with its priorities and strategies. In particular, an important role is played by the implementation of a spatial data geoportal at Local Administration level (Timişoara City Hall) to streamline the data workflow and provide easy access to it in order to increase the visibility of cultural and historical heritage of the municipality. The need of this geoportal arises from the fact that Timişoara has the widest architectural heritage area in the country, of important value to both Romania and Europe. The preservation of this cultural heritage is a duty for the authorities and also for the owners. The present paper brings forward proposals and trends in implementation of a dedicated geoportal for the management of heritage objects to complete the existing urban GIS primarily aiming to contribute to fostering the urban planning and the sustainability of the “European capital of culture” project. This geoportal should include the 3D models of the cultural heritage objects for better preservation over time or restauration purposes and offer virtual tourism tours if they are made available by means of webGIS. That is why, the authors propose a webGIS solution in order to make the geoportal available on the City Hall's webpage. The actuality of the paper is given by the fact that preserving cultural heritage and historical sites represents an important issue that must be taken into account when urban planning projects are required for developing the model of urban growth

Geodetic studies with significant contribution to landslide monitoring in south-western Romania – area with high risk potential

Cilj rada je upoznavanje s geodetskim istraživanjima koja su usko povezana s modeliranjem odrona zemlje i moraju se primijeniti za trajno nadziranje područja u kojima dolazi do geomorfoloških opasnosti. Iako se ponekad nedovoljno cijeni doprinos geodeta nekim projektima za nadziranje odrona u svrhu razvoja sustava za rano upozorenje ili izradu karata s prikazom mogućih opasnosti, kako je navedeno u FIG radnoj grupi (2006) [20], i promatra ih se jedino kao dobavljače izmjerenih geometrijskih podataka, njihov je doprinos važan u modeliranju dinamičkih sustava, kao što su strateške konstrukcije (brane, visoke zgrade itd.) ili odroni zemlje te u interpretaciji podataka. Istraživanje ponašanja tijekom vremena nekog objekta zahvaćenog odronom uključuje geodetska mjerenja obavljena u ranije utvrđenim vremenskim intervalima primjenom najsuvremenijih tehnologija, koje omogućuju obradu i pregled tako dobivenih podataka u trodimenzionalnom sustavu. Uz to, cilj je postaviti okvir za oblikovanje i optimizaciju mreža za nadziranje biranjem optimalnih istraživačkih metoda.This paper aims at presenting geodetic studies that are in close connection with landslide modelling and must be used for continuously monitoring the areas affected by geomorphological hazards. Although sometimes the geodesist’s contribution to certain projects for landslide monitoring meant to develop early-warning-systems or risk maps is not adequately appreciated as stated in FIG Working Group (2006) [20] and he is only seen as supplier of measured geometric data, the geodesist has a significant contribution through his abilities regarding the modelling of dynamic systems, like strategic constructions (dams, tall buildings etc.) or landslides and data interpretation The study of how an objective affected by landslides behaves in time implies geodetic measurements performed at pre-set time intervals using state of the art technologies, which allow processing and review of data thus obtained in a three-dimensional system. Moreover, the goal is to set the stage for the shaping and optimization of monitoring networks by choosing the optimal research methods to be used
