This study aims to make a comparison between flooded areas identified using the flood bands obtained with HEC-RAS hydraulic model, and the NDWI index resulted by processing Landsat 7-ETM+ satellite imagery. The study area was the upper sector of the Jijia River in Moldavian Plateau (North-Eastern Romania), affected by the July 2010 flood that was well caught in the satellite images. During that event the level of the Jijia River at Dingeni hydrometric station reached a value of 579 cm, far exceeding the level of flooding. Performing different flood simulations on the concerned river sector, a flooded area of 15.80 km has been revealed when applied the NDWI index, and a flooded area of 16.26 km when used the HEC-RAS hydraulic model. Following the field analysis, the values obtained with HEC-RAS are validated. The flooded area smaller by 0.46 km in the case of images Landsat 7-ETM+ could be explained by errors due to resolution or cloudiness.

In Devedamı area, Central Anatolian Ophiolites (CAO) are represented by Late Cretaceous massive hornblende gabbroic rocks, which contain hornblende, plagioclase and clinopyroxene in a holocrystalline granular and rarely holocrystalline porphyric texture. Mineralogical analyses show that the brown-green amphiboles are magnesiohornblende in composition. Geothermobarometer calculation suggests that the amphibole was possibly crystallized from a water-rich magma (H2O melt: ~5.41 wt.%), with ∆NNO 1.57-2.34 and logfO2 (-13.59 -13) in ~2.5 km oceanic depth .

Abstract. The results of geoarchaeological and archaeological research at the Rychnowo V site are presented. The archaeological site is located on the moraine plateau between two subglacial tunnel valleys currently drained by the upper Drwęca and Grabiczek Rivers. Relief of the moraine plateau is varied by hollows on post-glacial depressions of varying size and degree of filling. These lakes were formed in the Late Glacial and were filled in the Holocene by organic and clastic deposits. At the archaeological site, several settlement phases have been identified related to the Lusatian (main phase) and Wielbark cultures, Early and Late Medieval and Modern periods. Not found in the site permanent or long-term settlement. The site should be considered as group of rather short-lived camps. The most numerous traces of Lusatian culture are not a single phase, but rather multiple returns to the same area at short intervals (the homogeneous ceramics). The activity of the people of Lusatian culture (connected not with cultivation but grazing) at the beginning of the Subatlantic led to slope erosion and soil fossilization in endorheic depression.

The Vistula flood plain has a very complicated structure both in horizontal and vertical layout. This applies to both the facies' formation of the sediments and their stratigraphy. Within the site, two areas with distinctly different types of sediments can be distinguished (Fig. 6). The first refers to the extensive zone of sandy-gravel channel sediments from Late Glacial in the lower part and Subatlantic in the upper part. The second area includes the oxbow lake sequences. The Early Atlantic series, both the channel and the oxbow lake sequences of „Old Vistula”. The study confirmed the position suggested by Bąkowski [11], that the „Old Vistula" has been excavated, taking into account previous morphology. It was probably a lowering of the Early Atlantic abandoned channel.

The subject of research in the paper are the settlements and their functional development, which is the basis for the sustainability in a demographic, economic and social sense. The functional development is conditioned by several factors, such as physicalgeographical, social, economic and political, and is manifested by the presence of various economic and non-economic activities. The intensive changes in the human activities and needs are reflected in the functional characteristics and functional differentiation of the settlements, their role in the administrative-territorial organization, their place in the hierarchy of settlements, the gravitational power of the settlement and the extent of their sphere of impact. The functional development of the settlements is a potential for pulsating the development of micro, meso and macro levels and for balanced spatial, demographic, economic and regional development. The disproportion in the functional structure is a serious problem that complicates the network of settlements and affects their overall sustainability. The emphasis is placed on some of the factors that are a prerequisite for the functional structure of the settlements in Republic of Macedonia, such as the number of population, administrative-territorial organization, geographical characteristics of the area, etc.

Atmospheric precipitation is one of the most important features of the climate. The research of the territorial distribution of the precipitation amount has a considerable practical, applicative and theoretical interest. Thus, the study of all the extreme and complex conditions of formation and falling of precipitation in the central area of the Romanian plain is necessary for the use of water according to the distribution of the precipitation regime as well for the prevention and combating on their negative effects. These may have various causes: frontal rainfall in the case of Atlantic cyclones and Mediterranean cyclones on various tracks, and convective cells forming within the air masses or under the action of radiation cooling processes or by the development of thermal convection (clouds with vertical development). In this paper, we have analyzed the synoptic conditions that generate precipitation in the central part of the Romanian Plain. Thus, with the help of the ROCADA database, all the days between 1981-2013 time period that gathered more than 10 mm amount of precipitation were extracted. The data were chosen for an area delimited by 44°42’ and 43°37’ N, and 23°56’ and 26°35’ E coordinates, assigned to our study area. The days were analyzed from a synoptic point of view using the maps available in the Global Forecast System reanalysis, on the www.wetter3.de website. This brought about seven synoptic causes that generate precipitation, represented by the Atlantic cyclones, Mediterranean cyclones with a type I, II and IV track according to the Bordei-Ion classification [1], high altitude cut-off low cyclones and by the high atmospheric instability periods represented by the long-wave troughs and also by the warm air advection in a high pressure atmospheric condition.

Complex political and geographical circumstances in geopolitical space of Bosnia and Herzegovina, in the nineties of the last century, led to the entity division of Bosnia and Herzegovina, according to the criteria of the ethnic majority (Republic of Srpska) and bipolar ethno-geographic structure (Federation of Bosnia and Herzegovina). When accessing the issue, we start from the premise that contemporary demographic characteristics and processes in B&H have a political-geographical dimension. Mutual conditionality and interaction of political-geographical processes and demographic characteristics condition the sustainability of Bosnia and Herzegovina as a complex geopolitical unit, which is ultimately based on specific ethno-demographic formula 1+2+3, or more precisely, one country, two entities and three constituent people and religions. The subject of research in this paper will be essentially based on a comparative analysis of the Census in Bosnia and Herzegovina from 1991 and 2013 and identification of demographic changes in territorial deployment and ethnic structure of the population. The purpose of this paper is to indicate that the political-geographical processes, military conflicts, specific consequences and recurrence of the war period in Bosnia and Herzegovina in the nineties of the last century had a decisive influence on the contemporary spatial distribution and ethnic composition of the population. The paper is planned to be realized by general, as well as special methods of geographical research and data processing techniques (statistical, cartographic, graphical, GIS analysis), which are consistent with research of influence of political-geographical processes to contemporary geodemographic characteristics of Bosnia and Herzegovina.

Land use and land cover integrate various aspects of natural and socio-economic features of the environment. Land use and cover change reflect the interaction among the environmental features and processes and human activities. After the collapse of the socialism regime in 1989, Romania has undergone significant changes at the level of socio-economic and institutional profile, which determined land use scientists to consider our country to be an experimental territory for land use research. Considering land use and cover plots as pieces of landscape configuration, landscape metrics can provide valuable information about structural changes occurred in land use and cover spatial pattern. Using the Suceava River Basin from Romania as a case study, a hybrid geographical approach applying landscape metrics and GIS techniques was applied to analyse the spatial and temporal dynamics of land use and cover pattern changes between 1990 and 2012. In order to assess the land use and cover changes, we used a series of relevant landscape metrics at class and landscape level in order to quantify the landscape composition and its spatial configuration. The analysis was carried out using CORINE Land Cover datasets from 1990, 2000, 2006 and 2012 by means of geographic information systems to present the spatial distribution of the data, while FRAGSTATS software was employed to process landscape metrics in order to generate statistics about landscape structure. The results highlight an increase in the number of patches and edge density, while the mean patch size decreased during the span of 22 years. Consequently, the landscape structure of Suceava River Basin became more fragmented and heterogeneous. We hope that the present approach will underline the importance of using landscape metrics in monitoring land use and cover changes over time by decision makers as a powerful basis of sustainable land use planning at the entire basin level.
