Land Degradation Within the Bahluieţ Catchment
DOI 10.1515/pesd-2016-0008 PESD, VOL. 10, no. 1, 2016 LAND DEGRADATION WITHIN THE BAHLUIEŢ CATCHMENT Ionela Popa1, Ion Ioniţă2 Key words: land degradation, soil erosion, gullying, landslides, sedimentation Abstract. The Bahluieţ catchment, located in the Moldavian Plateau, at the contact between the Jijia Rolling Plain, the Suceava Plateau and the Central Moldavian Plateau, has 54,866 hectares in size. The sculptural landforms are prevailing, described by elongated rolling hills, and are underlain by the Bessarabian layers laid in marine brackish facies. In turn, the typical plateau relief (Coasta Iasilor and the eastern border of the Suceava Plateau) is developed in coastal facies also Bessarabian in age. This paper focuses on the spatial distribution and intensity of land degradation processes and associated controlling factors within the Bahluieţ catchment. The most characteristic geomorphological processes, playing an essential role in the morphogenesis of the landforms are soil erosion and landslides, while gully erosion and sedimentation have a reduced intensity. Soil erosion is ubiquitous, being the process with the highest extension. Therefore, the soils on the arable land, affected by moderate-excessive erosion, hold a weight of 38%. The slopes subjected to landslides are stretching on 19,040 ha, representing 35% of the studied area. Nowadays, most landslides show high degree of stability, due to the drier period of time since 1982. The gully erosion has a reduced incidence resulting from the prevailing Bessarabian clayey-sandy facies. The average rate of sedimentation in reservoirs, after the year 1986, is around 2 cm yr-1. Land degradation within the Bahluieţ catchment occurs on steeper slopes, mainly in the shape of cuesta fronts, usually northern and western facing, but also on some degraded cuesta back slopes. -
Exceptional Floods in the Prut Basin, Romania, in the Context of Heavy
1 Exceptional floods in the Prut basin, Romania, in the context of 2 heavy rains in the summer of 2010 3 4 Gheorghe Romanescu1, Cristian Constantin Stoleriu 5 Alexandru Ioan Cuza, University of Iasi, Faculty of Geography and Geology, Department of 6 Geography, Bd. Carol I, 20 A, 700505 Iasi, Romania 7 8 Abstract. The year 2010 was characterized by devastating flooding in Central and Eastern 9 Europe, including Romania, the Czech Republic, Slovakia, and Bosnia-Herzegovina. This 10 study focuses on floods that occurred during the summer of 2010 in the Prut River basin, 11 which has a high percentage of hydrotechnical infrastructure. Strong floods occurred in 12 eastern Romania on the Prut River, which borders the Republic of Moldova and Ukraine, and 13 the Siret River. Atmospheric instability from 21 June-1 July 2010 caused remarkable amounts 14 of rain, with rates of 51.2 mm/50 min and 42.0 mm/30 min. In the middle Prut basin, there are 15 numerous ponds that help mitigate floods as well as provide water for animals, irrigation, and 16 so forth. The peak discharge of the Prut River during the summer of 2010 was 2,310 m3/s at 17 the Radauti Prut gauging station. High discharges were also recorded on downstream 18 tributaries, including the Baseu, Jijia, and Miletin. High discharges downstream occurred 19 because of water from the middle basin and the backwater from the Danube (a historic 20 discharge of 16,300 m3/s). The floods that occurred in the Prut basin in the summer of 2010 21 could not be controlled completely because the discharges far exceeded foreseen values. -
The Economy of a Regional Metropolis. Case-Study: Iaşi, Romania*1
THE ECONOMY OF A REGIONAL METROPOLIS. CASE-STUDY: IAŞI, ROMANIA*1 Claudia POPESCU Claudia POPESCU Professor, Faculty of International Economics and Business, Academy of Economic Studies, Bucharest, Romania Tel.: 0040-213-319.1900/378 E-mail: [email protected] Abstract The city of Iaşi with a population of over 300,000 people is the biggest European Union city at the border with the former-Soviet space. The article, part of an extended study on territorial development of Iaşi and its peri-urban area, focuses on the role of the city to trigger regional growth and to enhance cross border cooperation. Recent processes at work generating economic cohesion and integration are explored drawing on the catalytic factors of development and the specialization of local economies. The paper discusses also the externalities of urban growth such as the urban sprawl that causes land use conflicts at the rural-urban fringe. It argues that human capital and higher birth rates than the national average are the strengths, and low connectivity and accessibility are the weaknesses for regional growth. The regional polarization of the city is based on the supply of high level services over the entire North-East Region and opportunities to cross border cooperation through the expansion of an agro-alimentary supply-chain are highlighted. Building on the main capabilities and assets of the * The paper is part of the research conducted between 2009 agglomeration economies of Iaşi, the paper finally and 2010 in the view of drafting the Master Plan of the Iaşi identifies some of the mechanisms and structures Municipality, Romania. -
Water Developments and Their Impact on Runoff in the Upper Tisa Catchment
Water developments and their impact on runoff in the Upper Tisa catchment Károly Konecsny The 157 200 km2 large catchment of the River Tisa1 is situated in the eastern part of the Carpathian Basin, also known as the Central Danube Basin. The upper catchment down to the village Záhony is 32 782, that down to Tokaj 49 449 km2 large. The origin of the name Tisa is still unclear, some linguists trace it back to an Indo European root supposed to mean muddy, or silty. In Roman documents the river is mentioned under the names Parsiou, Pthirus, Tigas and Tisianus, while in the mediaeval Latin chronicles in the forms Tisia and Tysia. Keywords: hydrology, Upper Tisa, Carpathian Basin The Upper Tisa and her tributaries in the Ukraine The headwaters of the Tisa are in the Maramuresh Alpine Mountains, the name Tisa is used downstream of the confluence of the Chorna Tisa and Bila Tisa. Of her 962 km total length, the mountain section is only 200 km long. From the confluence of the Chorna Tisa and the Bila Tisa down to the mouth of the Vi§eu the average slope of the valley floor is very steep, 6.33 m/km, between the Vi§eu and the Tereblja 2.28 m/km, flattening down to Tiszabecs to less than l m/km. Over the mountain section the valley is narrow, the river having carved her up to 50 m wide bed between steep banks. The normal depth is a few decimetres. Beyond her emergence into the plains at Hust the Tisa becomes a typically lowland river meandering in a spreading valley. -
Impact of the Abundant Precipitations of 22-27 July 2008 in the North and North-East Moldova
PRESENT ENVIRONMENT AND SUSTAINABLE DEVELOPMENT, NR. 3, 2009 IMPACT OF THE ABUNDANT PRECIPITATIONS OF 22-27 JULY 2008 IN THE NORTH AND NORTH-EAST MOLDOVA Liviu Apostol1, Ovidiu Machidon2 Key words: abundant precipitations, floods, damages Abstract: In the last decade of the month of July 2008, the appearance and the persistence of a retrograde cyclone for a few days in the northern and northeastern area of Moldova determined the production of precipitations that had especially high intensity and that were taken over by the Prut and Siret Rivers and their tributaries. The high flow of the Siret River’s tributaries was mainly caused by the large quantities of precipitations fallen in the area in contact with the higher flanks of the Carpathians. The flash flood flow registered a few days later by the Prut River at the entrance to Romania was mainly caused by the rains fallen in the southwestern area of Ukraine. This paper presents the evolution of the process, quantities registered by the meteorological stations and the rain-gauge stations, the hydrological consequences and the impact of these pluviometric events on the environment of the northern and northeastern Moldova. Floods of the end of July and beginning of August 2009, in the northeastern part of Romania follow closely those of the end of 2005. The last decade witnessed in this area a succession without precedent of very hot and dry periods and rainy periods, some of them constituting records of the entire observation period. The cause was, as for the majority of Moldova catastrophic floods, a retrograde cyclone. -
Geomorphological Observations on the Valea Oilor Catchment
LUCRĂRILE SEMINARULUI GEOGRAFIC “DIMITRIE CANTEMIR” NR. 35, 2013 GEOMORPHOLOGICAL OBSERVATIONS ON THE VALEA OILOR CATCHMENT Ionela Popa1 Abstract. The Valea Oilor catchment, located in the Moldavian Plateau, at the contact between the Suceava Plateau in the west and the Jijia Rolling Plain in the east, has 9.723 hectares in size. The present study required both a Geographical Information System (G.I.S.) approach by using topographic maps at a scale of 1:5.000 in order to analyse the geomorphometric parameters, and field mapping. The general monoclinal structure of the surface geological layers resulted in development of a cuesta landscape. The sculptural landforms, represented by hilltops and especially slopes, with the average altitude of 150 - 200 meters, are prevailing. Valea Oilor valley highlights the first structural asymmetry, where the left valleyside is a south-looking cuesta backslope, while the right valleyside is a cuesta front with northern orientation. Land degradation processes are very active through soil erosion, gully erosion, landslides and sedimentation. Landslides are the most characteristic geomorphologic process, while gully erosion has a reduced incidence. Key words: G.I.S., cuesta, soil erosion, landslides 1. Introduction The Valea Oilor catchment, located in the North-Eastern Romania is integrated in the Bahlui hydrological system. The catchment lies between the Suceava Plateau, in the west and the Moldavian Plain (Băcăuanu V., 1968) or the Jijia Rolling Plain (Ungureanu Al., 1993) in the central and the eastern part. This involves a large range of physical and geographical conditions which influenced the formation and the evolution of the local landscape, with multiple implications concerning the present day geomorphic processes. -
The Distribution of Salt Massifs and The
Section Hydrology and Water Resources THE DISTRIBUTION OF SALT MASSIFS AND THE EXPLOITATION OF ANCIENT AND CURRENT RESERVES OF MINERALIZED WATERS WITHIN THE SIRET HYDROGRAPHICAL BASIN (ROMANIA) – CASE STUDY FOR THE EASTERN AREA OF THE EASTERN CARPATHIANS Professor Dr Gheorghe Romanescu1 Associate Professor Dr Marius Alexianu2 Research Assistant Dr Andrei Asăndulesei3 1 “Alexandru Ioan Cuza” University of Iași, Faculty of Geography and Geology, Department of Geography, Romania. 2 “Alexandru Ioan Cuza” University of Iași, Faculty of Letters, Romania. 3 “Alexandru Ioan Cuza” University of Iași, Interdisciplinary Research Department – Field Science, Romania. ABSTRACT The present study proposed to underline the importance of salt-water reserves in the life of the local communities and to quantify the value of certain basic elements that can affect their chemical properties. The salinity does not produce pollution, but only a restriction of water use in certain domains. There is a close connection between the genesis of salt reserves and the emergence of springs, the type of rock, the regional and local climatic regime, the type of hydrographical network supply, and the liquid discharge. The waters within the Carpathian mountainous and sub-mountainous area can be influenced directly by the emergence of salt deposits on the surface. The poorest springs are situated in the area of the Moldavian Subcarpathians, where there are diapiric outcrops. The Neolithic settlements in the east of the Eastern Carpathians attest the oldest use of salt springs in the world. Some springs may be underlined by the humans through animals, mostly the sheep, which looked for salinized fields for their optimal water intake. -
The Assessment of the Cultural Heritage's
European Journal of Science and Theology, April 2013, Vol.9, No.2, 233-242 _______________________________________________________________________ THE ASSESSMENT OF THE CULTURAL HERITAGE’S VULNERABILITY TO FLASH FLOODS IN BAHLUI RIVER BASIN, IASI COUNTY Irina Dana Tutunaru*, Tudor Viorel Blidaru and Ionuţ Claudiu Pricop Prut Bârlad Water Basin Administration, 10 Th. Văscăuţeanu Str., 700462, Iasi, Romania (Received 25 June 2012, revised 10 February 2013) Abstract Floods are natural phenomena with significant impact on population, material goods and landscape. Flash floods are characterized by a high degree of risk, primarily due to reduced possibilities to make effective forecasts, but also because of weather and climatic characteristics that changed in the last decades, thus limiting the possibilities of application of appropriate defense and adaptation measures. In this context, the paper aims to make a preliminary assessment of vulnerability to flash floods, using hydrological simulation models based on GIS techniques applied in sub- basins, allowing a ranking of risks within relevant locations, especially concerning the cultural heritage in the county of Iasi. The development of methods for addressing such conditions creates the scientific basis for planning the required resource allocation for the protection of the cultural heritage hence for the implementation of water resources management plans and territorial development plans. Keywords: flash floods, cultural heritage, GIS, hydrological simulation 1. Introduction It is a well-known fact that each nation is defined, amongst other, by its history, its religious beliefs and its culture. Iasi city and Iasi County contain a large number of monuments and historical sites classified as cultural heritage, which cover a long historical period, from the famous Cucuteni culture to the medieval churches, from the Iron Age until the 20th century. -

This overall decline in population is not entirely true for the towns and cities of the North-East Region, as during the same period they recorded both decreases and increases in population due to positive natural balance. The North-East Region (partially superimposed over the historic region of the western Moldova) is considered the poorest region in the European Union and a disadvantaged area. The rural young population of Moldova is a reservoir which supplies urban areas and especially large cities. In these circumstances, the small towns of the North-East Region are seeking balance (demographic, economic, functional). This paper examines the demographic evolution of the small towns located in the area under analysis, in the post-communist period, illustrating the types of fluctuations in statistical methods as regards demographic changes and the risk of depopulation in the future, correlated with a lower overall population of Romania. Keywords : demographic evolution, small cities, post-communist, North-East Region INTRODUCTION The analysis of demographic trends is an important area for the adoption of appropriate policies to prevent depopulation. The North-East Region has a special status as the poorest European Union Development Region, the east central area of this region being a disadvantaged area (Iano ş et all., 2009), while registering a generally positive natural balance during 1990-2007. -

Sadoveanu 3, Romania Received 10 March 2013; received and revised form 29 March 2013; accepted 7 April 2013 Available online 1 June 2013 Abstract The influence of 3 tillage treatments (moldboard plough – MT, chisel – CT, disc-harrow – DT) and 50 rapeseed cultivars (41 hybrids and 9 open-pollinated varieties) was assessed within a 2-year study that was carried out on a cambic phaeozem (RSTS-2003) in Suceava Agricultural Research and Development Station for highlighting farmer oriented crop management options regarding tillage and rapeseed cultivar. MT>CT>DT in terms of yield for the entire period, and all pairwise comparisons showed significant (p≤0.05) differences between treatments. The differences among cultivars of the same seed company were insignificant (p≤0.05). Despite having the highest costs, MT remained the most efficient tillage option in Suceava Plateau when compared with both minimum tillage treatments. Keywords: tillage, cultivar, yield, economic. 1.Introduction Oilseed rape is the third most important source of vegetable oil [2] used both in human Nowadays, the major challenge became nutrition and animal feeding, and for biofuel as it achieving food security for more than 7 billion produces at least two times more oil per hectare than people, a world population that is projected to reach soybean [3].
