Morphometric features of the river network from the Bârlad catchment
Abstract: After a brief presentation of the Bârlad catchment, the hydrographic network is analyzed using the Horton-Strahler classification system. From the amount of morphometric parameters, the drainage and the slope patterns are taken into consideration for the entire Bârlad catchment and for the 13 hydrometric stations in the catchment that have data on water flows and suspended sediments. From those there were chosen the Vaslui hydrometric station as representative for the geomorphologic units of the Bârlad catchment and the Feldioara hydrometric station for the Berheci catchment. Based on the analyzed patterns there were determined a series of morphometric parameters specific to the river network for all the 13 analyzed stations and from their comparison one can see obvious differences between the obtained values for the basins in the Central Moldavian Plateau and the ones in the Tutovei Hills.

The Studineț Basin (Tutova Hills). Morphometric Indicators and Correlations
Abstract: The morphometric analysis doesn’t imply just the quantitative description of the relief, although it is frequently limited to it, but also a methodological approach that allows the typological classification of landforms and establishing some significant correlations between the selected parameters and other geomorphologic, geologic indicators etc. The testing and validation of such analyses is performed upon representative samples on different scales. This article aims to interpret some morphometric indicators and correlations within the Studineţ hydrographical basin (9669 ha), located in the central part of the Tutova Hills, in the eastern part of Romania. The region’s relief is grafted on sandy-clayey and clayey-loamy deposits from the Kersonian and Meotian, being characterized by a relatively high fragmentation for a hillyregion (Jeanrenaud, 1971, 1995). The maximum altitude gap ranges between 108.9 and 485.5 m, and the relief energy values facilitate morphodynamic imbalances expressed through different geomorphological processes. The main characteristic is the presence of cuestas with morphometric, morphodynamic and land use asymmetries. The present scientific approach analyzes every derived map by interpreting the unclassified rasters (pixel value) and the classified ones (class value), comparing the relevance of the results to obtain the optimal number of classes and to establish the limits that have the best geomorphological level of significance. Given the region’s features, the analysis of cuestas was favored to differentiate the cuesta fronts and backslopes. Finally, on a representative perimeter within the basin, the raster histograms (hypsometry, declivity, exposition) were compared, to highlight the differentiations caused by the map scale and pixel resolution.

Changes in air temperature and precipitation and impact on agriculture
Abstract: Air temperature and precipitation are among the main factors for agricultural production. The aim of the present research work is to analyse changes in air temperature and precipitation in non-mountainous part of Southern Bulgaria in terms of the opportunities for the development of agriculture in the region. The trend in variability of seasonal and annual air temperature and precipitation is determined by the linear regression method. An analysis of the combination between air temperature and precipitation gives a tool to classify the climate according to dry and wet conditions of the territory. For this purpose the Gaussen-Bagnouls classification method is used in the present paper. In terms of air temperature, the investigated area is favourable for growing thermophilic plants. In order to investigate thoroughly the impact of climate change, the quantitative research has been complemented by a qualitative study – case study of farmers from the region of Stara Zagora. Case studies show that farmers are vulnerable to various degrees to the expected annual variability and average changes in yields depending on farm size, crop varieties and availability of irrigation.
Keywords: air temperature, precipitation, Gaussen-Bagnouls classification, case study of farmers, climate change, agriculture

The sediment transport of the Siret River during the floods from 2010
Abstract: Beginning with 2004 in the Siret River Catchment there occurred exceptional flash floods that exceeded the maximum historical values recorded, on the main river and on its tributaries (2004, the Trotuş River; 2005, the Siret River, the Trotuş River, the Bistriţa River, the Putna River; 2006 – the Clit River from the Suceava River Catchment; 2008, the Siret River, the Suceava River). The 2010 summer flood from the Siret River also falls in this category. This paper uses hydrological data (water discharge, suspended sediment discharge) between the 20th of June and 10th of July 2010 from 5 gauging stations located on the Siret River: Siret, Hutani, Lespezi, Dragesti, Lungoci, and also meteorological data (rainfall) measured at different gauging stations from the Siret River Catchment. The rainfall recorded in this time of the year in the catchment was very high, with values up to 210 l/m2 in approximately 10 days. The hydrographs of the flash flood indicate the fact that the transit of the water trough the reservoirs system from the Siret River (Rogojeşti – Bucecea and Răcăciuni – Bereşti –Călimăneşti – Movileni) reduced the maximum water discharge with values between 7-27%. The values of the maximum sediment discharge also recorded a reduction while transiting this reservoirs system with approximately 60%. The evolution of the Siret river bed channel during this flood (aggradations with values between 15-100 cm and degradations starting from 65 cm until 200 cm, in different moments of the flood) is influenced by the high values of the water and sediment discharge and by anthropogenic interventions on the river bed (pit-ballast, regularization of the river bed, reservoirs). Processing the hydrological and meteorological data recorded during the flood (20th of June – 10th of July 2010) indicates two important features of this event: the climatic variability – exemplified by the big values of precipitations from the catchment and the anthropogenic impact revealed by the transit of the flood wave and the evolution of the river bed.

Rural Development Potential of Peripheral Areas – Case Study Bochov (Bohemia)
Abstract: This paper analyzes the microregion of the town of Bochov in the Karlovy Vary Region as an example of an area located in the internal periphery of Czechia and at the same time indicating typical characteristics of the borderland, the result of postwar population transfer. Long-term population development can be characterized by a decreasing population and at the same its concentration in the center. Educational attainment statistics indicate unfavorable findings. Employment is dependent on commuting. Possible strategies include ensuring good living conditions for the population, supporting small and medium businesses, regional marketing, developing tourism and landscape stewardship, and maintaining the rural characteristic of the microregion. Microregions such as the Bochov microregion do not nor cannot have the same preconditions for development as central microregions. Their development should be focused on improving quality of life for local residents and visitors.
