    Kurzfassung: In the summer of 2008 the Prut river recorded a historical flow of 7140 m 3 /s at its entrance into Romania. This flow was the highest ever recorded of any Romanian river. The high value was generated by high amounts of rainfall recorded first on the territory of Ukraine and then in Romania. Unfortunately, there were some discrepancies between the data transmitted and intercepted from the Meteorology National Agency and Hydrology and Water Management National Agency. This is why the amount of precipitation which fell over the territory of Ukraine could not be monitored in time and punctually. Nor could the high flood wave moving rapidly from the upper basin to the lower basin. The high flow of the upper Prut caused the accumulation of an immense quantity of water in the Stanca–Costesti reservoir. Under the conditions of precipitation occurring in the lower river basin as well, the levels reached the flood quota and the reservoir reached the maximum accepted capacity, with 0·1% insurance. The release of supplementary water quantities from the reservoir would have produced catastrophic floods downstream. Keeping the water in the reservoir could have broken it and the flooding, through backwater eddies, or the riverbank settlements. In such a case, it would have produced the greatest tragedy in the hydrological history of Europe. The most significant damage was produced upstream of the barrage, next to the localities of Radauti Prut and Baranca–Hudesti, as well as in the area of the reservoir, as a result of the phenomenon known as ‘remuu’, or backwater eddies. The floods of the Prut river occurred between the end of July and the end of August. Copyright © 2011 John Wiley & Sons, Ltd.

    An inter‐basin backwater overflow (the Buhai Brook and the Ezer reservoir on the Jijia River, Romania)

    Kurzfassung: During the last few years, the north‐western part of Romania has been affected by catastrophic floods with most of the watercourses reaching their highest recorded discharges. This study reports the generation of a numerical terrain model and the simulation of a backwater phenomenon at elevation steps according to the volume of water accumulated at the confluence of the Buhai Brook with the Jijia River. The hydrological data are complemented by rainfall data and the careful recording of the flood behaviour during the entire period of its development. The main aim of the study is to identify the causes of the backwater phenomenon and to highlight the material damage inflicted on the town of Dorohoi. At the same time, the study uses cartographic model that was developed to establish which areas are at risk of flooding at various levels of probability. The catastrophic flood began on the Buhai Brook, a slow‐flowing stream that drains the areas to the west of the town of Dorohoi and discharged into the upstream sector of the Jijia confluence. The flood caused two types of backwater waves: one behind the bridges and the houses built on the floodplain and a second that followed the course of the main stem (Jijia) upstream from the confluence, flooding the Ezer Lake, which was created specifically to attenuate such floods. The spillway backwater phenomenon was inter‐basin as it did not occur in a single hydrographic basin. The causes of the catastrophic flash flood and of the inter‐basin backwater overflow are natural but also reflect anthropogenic influence. After the lake filled, the discharge into the Jijia was controlled and the flooding downstream was thus greatly diminished. Though fortuitous, the backwater flooding was important in mitigating the impact of the flood wave from the Jijia River. Copyright © 2013 John Wiley & Sons, Ltd.

    Kurzfassung: The hydrographic basin of the Miletin River is situated in the southeast of Europe, in a transitional temperate-continental climate, with considerable variations in the regime of precipitations. The purpose of this study is the spatial and temporal analysis of the mean seasonal discharges, meant to underline the need of implementing regulation projects for the Miletin stream. Furthermore, there are only a few specialized works on this hydrographic basin. The mean seasonal runoff presents significant seasonal and multiannual variations, caused by the high frequency of torrentiality, which characterizes the climate of the Miletin River area. Data from the rainfall stations of Nicolae Balcescu, Chiscareni, and Halceni, as well as from the hydrometric stations of Nicolae Balcescu, Sipote, and Halceni- downstream, respectively, were used. Unlike the stations with a natural runoff regime (Nicolae Balcescu, within the upper basin, Sipote within the middle basin, respectively), for Halceni-downstream (on the lower stream), the artificial runoff underlines a weak correlation with the rainfall regime. The data rows regard periods of 33-59 years, enough to conduct statistical analyses. Data from Halceni- downstream were analyzed, too, though the variables that characterize the hydrologic and rainfall regime within this region concern only 18 years. In the Miletin hydrographic basin, low and high discharge oscillations occur in all the four seasons. This characteristic is very different from those of the great hydrographic arteries that cross the east of Romania: Pruth and Siret.

    Kurzfassung: Recent climate changes mentioned in the Intergovernmental Panel for Climate Change (IPCC, 2013) report highlight the fact that in the past 50 years at the planetary level have occurred major changes in all climate components. In this regard the analysis of rainfall oscillations and of their impact on the hydric regime is particularly important, being witnessed in the surface and groundwater level variations. In the Suha River Basin, the year 2006 has been characterized by large rainfall quantities that have been generated, in particular, in June by persistent retrograde cyclonic activity (223 mm at Slătioara 3 hydrometric station, 269.1 mm at Gemenea 5 station, 271.6 mm at Valea lui Ion station and 351.8 mm at Stulpicani). On the main course of Suha, but especially on its tributaries (Gemenea and Slătioara) have been recorded very high flow rates (5% and 2% insurance) caused by the amounts of rainfall felt in a short time. To estimate the impact of rainfall on the Suha basin hydrological regime we used data collected by the Siret Basin Water Administration-Bacau, being analyzed the rainfall quantities, duration, intensity, tendency and effects.

    Loess-Scape in the Dobrudja Plateau (Romania). Landforms and Updated Typology
    Walter de Gruyter GmbH ; 2018

    Kurzfassung: The study of loess and loess-like deposits in Romania has developed considerably, over the years. C14 dating determined that the last three glaciations (Mindel, Riss, Würm) and, at least, two interglacial periods were recorded in the Dobrudja Plateau. Five other paleosol layers indicate the succession of the Quaternary interglacial stations. The loess of Dobrudja, is about 50 m in thickness. The term loess-scape is comprised of all the processes and forms specific to these deposits, which create a unique landscape, with local peculiarities. Natural and anthropic conditions created loessoid microforms (clastokarst) specific to the Dobrudja Plateau. The friability of loess-like deposits, the heavy rains, the lack of vegetation, the existence of a steep slope and of a low basic level, led to the development of a marginal (border) clastokarst on the western and northern side of the plateau (on the right of Danube bank). The aim of this study is to rename the microforms specific to loess-like deposits and to highlight new ones: solution clastic dolines, collapse clastic dolines, clastic resurgences (intermittent karst springs), piping clastic glacis, collapse clastic glacis, proluvial clastic glacis, clastic micro-waterfalls with clastic micro-cauldrons, clastokarstic curtains (drapes), and so on. Consequently, the loess-scape in the Dobrudja Plateau is distinct, just like the karstic, volcanic, glacial landscape, and so on. New clastokarstic microforms were highlighted and efforts were made to establish a proper terminology.

    The City-Port of Halmyris: An Integrated Geoarchaeological and Environmental Approach to the Last Roman Bastion on the Eastern Flank of the Danubian Limes
    Walter de Gruyter GmbH ; 2018

    Kurzfassung: The last Roman City on the eastern side of the Danubian Limes is Halmyris. It is a City-port which plays a primordially military role, situated at the link between the fluvial and the marine environment. The fortress is famous for its location at the foot of the legendary Peuce Island. Halmyris benefits from important natural resources from two environments with distinct characteristics: marine (Halmyris Bay) and freshwater (Danube Delta). When the city was founded, the St. George arm was the most important navigation artery of Danube. Therefore, the penetration upstream was monitored strictly by the City-port of Halmyris (customs). This study emphasizes on the existence of natural favorable premises for the city of Halmyris and it attempts to revitalize thematic tourism. The assessment of paleoenvironment evolution and present conservation stage has been achieved to improve the risk management plan.
