  • A methodological framework for the morphometric analysis of the fluvial islets along the Danube River in the Giurgiu – Oltenita sector

    Author: Andreea-Florentina Marin

    Abstract: This paper presents a methodology exclusively based on using the Open Source GIS Technology for the morphometric analysis of the fluvial islets along the Danube course. The study area corresponds to the Giurgiu-Oltenita sector, one of the sectors displaying a relative stability regarding the number and distribution of such geomorphological landforms. In order to identify and achieve a morphometric analysis of the Danubian fluvial islets, we suggest a set of eight parameters: the total number of fluvial islets, maximum length, maximum width, elongation ratio, area, perimeter, perimeter/area ratio and shape index. The necessary geospatial data used to compute the morphometric parameters have been obtained from cartographic documents and ortorectificated aerial imagery, while in order to obtain the final results, a graphical geoprocessing model has been created and run.

    Keywords: methodology, morphometric analysis, fluvial islets, Danube, graphical model, GIS.

  • Participatory research methods applicable in geographic studies

    Author: Cristina Posner

    Abstract: The aim of this article is to present methods of participatory research and PGIS participative mapping and their applicability to geographic studies. Participatory research has emerged as a reaction to the traditional pyramidal research approaches. 2014's Future Earth Agenda indicates that there are issues regarding a) the need for the co-creation of knowledge and integration of academic and non-academic knowledge and b) development of collaborative research with different stakeholders in order to address current global environmental challenges in a sustainable manner. After a theoretical introduction, the author presents the applicability of focus groups interviews and PGIS participative mapping in a trans-disciplinary project concerning the Lower Danube Floodplain evolution. The PGIS research field is a domain, which links GIS with the critical geography thinking being based on the implementation of participatory research methods. The current international policy of Future Earth is raising awareness about the importance of participative research methods and the article presents two practical applications of such methods.

    Keywords: participative research, focus group interviews, PGIS participative mapping, Lower Danube.
