Abstract	Deposit salt in Romania has extremely important reserves, considered even inexhaustible at the current exploitation level. The biggest salt resources are found in the intra-Carpathian arch, represented by Transylvania and Maramures. Most sources of salt outcrops are disseminated on the edge of the Transylvania Depression, in the diapir folds formed following salt migration. The salt mines – Turda, Praid, Ocna Mures, Ocna Dej, Ocna Sibiu, Cojocna, Ocna Sugatag – represented an important source of incomes, reason for which important human settlements formed around them. All these localities have turned nowadays into balneal and climacteric resorts that fully use the beneficial effect of the atmosphere within galleries (Praid, Turda). The most important incomes from tourism are represented by the galleries of the mines of Turda (one of the 10 wonders of the modern world) and Praid. The balneal and climacteric resorts also developed around the salt lakes installed in the areas of collapsed mines: Sovata, Ocna Sibiu, Ocna Dej, Cojocna. The most well known human settlements and the most important balneal and climacteric resorts, implicitly, are disseminated on the external branch of the Transylvania Depression (Sovata, Praid, Ocna Mures, Baile Figa, Cojocna thermae, Ocna Dej, Ocna Sibiu) and of the Maramures Depression (Ocna Sugata, Costiui, Vad). The oldest mining exploitation is situated at Figa (county of Bistrita-Nasaud) was founded around the year AD 3000. From this point of view, it is one of the oldest mining exploitations on Earth. The existence of the world-important archaeological site can invigorate the development of the surrounding localities, but mostly of the city of Beclean.

Abstract	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.

Abstract	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.

Abstract	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.

Abstract	The main objective of the paper is focused on water quality research in the village of Bivolari, Iasi County. The Bivolari settlement is situated in the Prut meadow and develops along the road connecting Iasi and Stefanesti. The research done in this paper starts from the collection of data on water pH, water LDO (oxygen concentration), CDC (dissolved salt content) and water temperature. The parameters were measured for 7 months using the HACH-LANGE multiparameter of the Geoarchaeology Laboratory at Alexandru Ioan Cuza University of Iasi (Inter-disciplinary Platform ArheoInvest). The study is structured in two sections: scientific substantiation and applicative research. The scientific substantiation part analyzes the water features in the context of the integrated management approach as well as an analysis of the quality aspects of the water supply. The applied research part required monthly field measurements in 50 fountains (without the winter season). The approached subject is is complex and up-to-date because the citizen is a priority for EU Member States (EUPAN, 2009): the aspect of “customer satisfaction” represents a capital priority. Finally, the database is structured into two categories: spatial information such as maps; tabular information attached to spatial data. The paper also follows the transition from the field of research into the field of application by presenting models of data representation, which are at the same time tools adapted to the practical needs. In order to achieve this goal, the concept of quality (both in terms of product - drinking water and local consumer) is defined and addressed in an integrated manner. Of the 50 wells monitored, only one had a water shortage in the last 10 years, and in two other cases there were problems with household waste and dead animals that damaged the water supply. Some fountains can dry at intervals of 3-4 years.

Abstract	Understanding how climate and land cover currently shape species distributions and community structure is crucial to inform conservation decisions. Unfortunately, limited information is available for the relative importance of climatic and land use variables in determining the distribution of amphibians and reptiles. Here, we studied amphibian and reptile communities from the Carpathian Mountains, asking (i) to what extent is the distribution of reptiles and amphibians determined by environmental gradients, (ii) does the response to these factors differ between amphibians and reptiles, and (iii) are reptile and amphibian communities at higher altitudes more similar to each other than communities from lower altitudes. We found that forests, pastures, and heterogeneous arable land best explain the composition of the herpetofauna, with mountain communities associated with coniferous forests, and lowland species with mixed or broad-leaved forests and pastures. Our results also suggest that reptiles and amphibians respond idiosyncratically to the influence of climate and land use. Reptiles responded more to land use and less to climate variables compared with amphibians. Of the three amphibian hybrids registered, one (Bombina) was associated with heterogeneous arable land. These results have potential implications for future conservation planning, especially in the light of global climate change and changes in land use. Hence, local and regional processes are important in shaping amphibian and reptile communities.

Abstract	Within the context of shoreline alteration, the impact of hydrotechnical works on coastal processes has been increasingly discussed in the literature. In this study, we analysed the Romanian deltaic littoral, which is situated between the mouths of the Chilia arm (North) and Midia Cape (South) of the Danube Delta, with a total length of 166 km. The present study examines the hydrotechnical works constructed at the mouth of the Sulina arm and the inlet of Portita. In 1858, the European Danube Commission (which was created in 1856 but whose projects were initiated previously to that date) built the first hydrotechnical works at the mouths of the Danube. The maritime sector between the two river mouths (the Sulina and the St. Gheorghe) is 33 km long and is impacted by maritime forces that run both parallel and perpendicular to the mouths of the river. The continuous advancement of dams, which currently reach lengths of 9 km, has altered the shore. As the dams advance towards the sea, the north–south current is forced to deviate from its original route. The northern current, which is at its maximum extent during the winter months, is eroding the areas located next to the Imputita brook (north) and the Sondei channel (south). These areas of the shore are also influenced by the southern current, which moves in a south–north direction and is at its maximum during the summer season when it pushes the northern current towards the “alluvial trap”. Therefore, the maximum erosion occurs next to the Imputita brook (north). In the “alluvial trap” located south of the advancing dams, the particle size of the sandy deposits is slightly different from that of deposits in the erosive sector of the Imputita-Sondei. The jetties curve south, which causes a slight decrease in the rate of the “Sulina bar” formation because the waves coming from offshore do not directly enter the channel mouth, and thus the deposition of alluvium is slowed. Lateral erosion is visibly increased between the two river mouths due to a decreasing alluvial budget. Intense erosive processes also affect the Razim-Sinoie coastal barrier, which closes the lagoon of the same name. The first major hydrotechnical alterations were erected in the 1970s (when channels connecting to the St. Gheorghe mouth were first dug, and contact with the sea was totally or partially interrupted), and the inlets and outlets of the lagoon complex are now human-controlled. The hydrotechnical works led to an alteration in the direction and force of the littoral currents as well as a decrease in the amount of alluvia, thus altering the sedimentary budget. Over 60% of the entire deltaic littoral is currently eroding and the other 40% is accumulating.

Abstract	The year 2010 was characterized by devastating flooding in central and eastern Europe, including Romania, the Czech Republic, Slovakia, and Bosnia-Herzegovina. This study focuses on floods that occurred during the summer of 2010 in the Prut River basin, which has a high percentage of hydrotechnical infrastructure. Strong floods occurred in eastern Romania on the Prut River, which borders the Republic of Moldova and Ukraine, and the Siret River. Atmospheric instability from 21 June to 1 July 2010 caused remarkable amounts of rain, with rates of 51.2 mm/50 min and 42.0 mm/30 min. In the middle Prut basin, there are numerous ponds that help mitigate floods as well as provide water for animals, irrigation, and so forth. The peak discharge of the Prut River during the summer of 2010 was 2310 m 3 s −1 at the Rădăuţi-Prut gauging station. High discharges were also recorded on downstream tributaries, including the Baseu, Jijia, and Miletin. High discharges downstream occurred because of water from the middle basin and the backwater from the Danube (a historic discharge of 16 300 m 3 s −1 ). The floods that occurred in the Prut basin in the summer of 2010 could not be controlled completely because the discharges far exceeded foreseen values.
