  • A summary of CRMD new research on landslides using multi-temporal InSAR techniques based on Sentinel-1 data

    Author: Iuliana Armaș

    Abstract: The new landslide research direction at CRMD aims to improve and develop new applications of ground-based validation techniques of satellite radar interferometry displacement products, based on Sentinel-1 data. The test area is the high slope instability ridge of the Carpathian and Subcarpathian Prahova Valley due to natural and anthropogenic factors. We use sets of single polarized synthetic aperture radar (SAR) satellite data acquired by historical (i.e., ERS-1/-2 and ENVISAT) and recent (Sentinel-1) satellites, and multi-temporal radar interferometry (InSAR) methodologies to provide maps of line-of-sight displacements. We apply some of the most advanced differential interferometric Synthetic Aperture Radar techniques at the moment, Persistent Scatterer Interferometry (PSI) and Small BASeline Subset (SBAS); both of them are applied for depicting areal or point deformations. Deformation maps and time series are integrated with Geographical Information System (GIS) multilayer analysis results derived from classical methodologies (i.e., geological and geomorphological methods), and field research. InSAR analyzes are calibrated and validated using GNSS techniques and GIS slope modelling based on Lidar and radar obtained DEMs. The short-term results are highly reliable interferometric measurements. On a long term, the results imply the understanding of slope dynamic in the context of major human environmental change. The latter achievement could offer the support to successful risk mitigation methodologies in mountain areas.

  • Navigating through historic Danube maps: a look at the fluvial islets between Giurgiu and Oltenita towns

    Author: Andreea-Florentina Marin

    Abstract: This paper presents a cartographical retrospective of the most relevant maps for the Danube River, focusing on the fluvial islets. The study area corresponds to the Giurgiu-Oltenita sector, one of the Danube's sectors displaying a relative stability regarding the number of such geomorphological landforms. If by the end of the 17th and the beginning of the 18th centuries the Danube River was drawn as a straight, wavy or curly lines, after this period the maps were made more detailed and precise, also depicting its fluvial islets and marshes. At the same time, information about the navigation, vegetation, topography and bathymetry is starting to be collected and mentioned. All these maps and aerial/satellite images provide an excellent record of historical locations and configuration of the Danube course and its islets.

    Keywords: historical cartography, old maps, fluvial islets, Danube River.

  • Relocated churches in the centre of Bucharest

    Author: Maria Bostenaru

    Abstract: The demolitions for the creation of the civic centre destroyed one fifth of the area of Bucharest. The destructions include a part of the architectural ambience of the streets, documented by Gheorghe Leahu for example in watercolours, important monuments such as the Brâncovenesc hospital or the Văcărești monastery. Apart of the demolitions, some monuments such as churches could be saved through relocation, an ingenuous method of the engineer Eugen Iordăchescu. This saved through relocation from their original place a number of monuments but lacking protection of the historical site. Other was demolished, the earthquake damage being abusively used as reason for the demolition. Although some religious buildings could be saved through that method, they were lacking the original monastery precinct and hidden behind blocks of flats. The boulevard of the so-called Victory of Socialism, named by some the Victory of Socialism on the city, cut the organic tissue resulting into streets transformed into dead ends of suddenly sectioned like the street of Rahova, sectioned by the boulevard, for which urban solutions are still looked for. The amplitude of the problem was clear in the international competition Bucharest 2000, won by the German office Meinhard von Gerkan. According to this solution, the monumental dimensions of the House of People could be put in scale only through the construction of some skyscrapers in the area remained park around it, where because of the rubbish from demolitions plants don’t grow adequately.

  • Methods of decision under certainty in applied emergency management

    Author: Ing. drd. Alexandru IFRIM, Ec. Raluca GHIMAN, Ph. Dr. Irinel Alexandru PRECUP

    Abstract: The present study shows how to develop information used during the decision-making process regarding procurement of equipment necessary to manage an emergency situation produced by floods.
    Moments method or Deutch-Martin method applies in case of decision making problems for which the criteria are equally important. The method has as a first step the normalization of consequences matrix. This method was used to analyse the purchasing of equipment for intervention in case of some major flooding events.
    Use of moments method optimally generates some clear results on procurement of goods and services that can be used in practice by the skilled professionals for emergency situations services.

    Keywords: Moments method or Deutch-Martin method, services for emergency situations, consequences matrix, normalized matrix.

  • Earthquake emergency plan analysis; a case study of Bacău County in Romania

    Author: Radu Ionescu

    Abstract: The work is structured as follows: First, it will briefly talk about an emergency plan’s function and structure. From this starting point the article will move on to the actual plan and highlight some of its major deficiencies. Special attention will be given to why having a model plan is a bad idea and to the link between emergency plans and policy/legislative context. In the end, a couple of the plan’s strong points will be discussed. The main point to be drawn from this plan’s analysis is that focusing on the policy and the deadlines it imposes without taking in to account local limitations leads to hastily, mass-produced plans, which are far removed from the recommended planning process.

    Keywords: Integrated Emergency Management, emergency planning, earthquake planning, landslide planning, emergency plan analysis.

  • 9/11, Elitism or Post-Modernism

    Author: Radu Ionescu

    Abstract: This paper will evaluate the way the events of 9/11 were interpreted. The evaluation will use two perspectives: Elitism and Post-modernism. The paper is structured as follows. After a short description of the events the concept of elitism is introduced. After that the focus moves on what disaster problems were identified after 9/11 from an elitist perspective, what policies this generated and what was the outcome of these policies. This same structure is kept in place in the second part of the paper where a similar evaluation happens, this time using post-modernism as a lens. The paper concludes that the two perspectives are complementary and proposes a solution grounded in cognitive psychology to what it sees as an issue of there being too many benefits associated with the creation of certain metanarratives.

    Keywords: Integrated Emergency Management, disaster narratives, elitism, post-modernism, disaster policy planning.
