“…Vougioukli et al [14] stated that despite the disadvantages of this methodology (mainly related to the quality of source data), it can be used as a supporting solution in the decision-making process of SHP construction. At the design stage of a new facility, the environmental impact of small hydropower plants should also be carefully considered [15], preferably using GIS tools [16]. When designing new SHPs and LHPs, it is equally necessary to take into account the spatial arrangement of already existing hydropower objects.…”

Proper design of hydrotechnical structures should meet the basic principles of sustainable development, i.e., the investment should be designed and made in technical terms, in accordance with the applicable standards and regulations, provide certain economic benefits and guarantee the absence of environmental hazards. The article examines the work of a Small Hydropower Plant (SHP) in Jaracz in technical and hydraulic terms. It also provides the analysis of the effect of changes in parameters such as water head, flow rate velocity, and shape of trash rack bars on expected SHP profits. The assessment of hydraulic performance consisted of investigating the impact of reduced flow rate and water head on power output and energy production. The analyses were carried out for the Francis turbine installed in the facility. Since the loss of channel capacity is shaped by plant debris accumulated on trash racks, the hydraulic performance assessment was extended to include the analysis of the species and weight composition of such accumulation on fine trash racks located in the inlet channel. Field research involved collecting organic material from the growing season (spring, summer) and post-growing season (autumn). Technical conditions were developed on the basis of the current technical condition of the inlet channel; there were also made simulations of its deteriorating state, as well as its impact on the received energy and economic benefits.

The Baseu catchment basin is situated in the northeast of Romanian and it is a right-side tributary of the Prut River. At the end of spring the most significant floods occur on the Romanian territory. They are due to the maximum amounts of rainfall and to snow melting. The phenomenon is also specific to the Baseu catchment basin. The last 20 years have witnessed a change in temporal manifestation, with maximum intensities during the summer (the months of July and August) when heavy rainfall is recorded. In the last 40 years, several critical episodes occurred, which endangered the lives of 79,000 inhabitants. In order to assess the hazard associated with maximum runoff, a floodable stripe with an assurance of 1% (once every 100 years) was modelled. Flood modelling involved the manipulation in GIS setting of the parameters of digital elevation model (DEM) and of their relations with the hydrological system. The main objective of the study is the modelling of an exceptional flood with a probability of 1%, similar to the one of 1969, when the Stefanesti gauging station recorded a flow of 330 m 3 /s. Based in the analysis of the hydrological data spanning over 50 years, recorded at three gauging stations, a maximum flow of 248.1 m 3 /s was determined (the Stefanesti gauging station), using the Pearson III probability curve. The findings have highlighted the significant vulnerability of the human settlements situated in the flood plain of the Baseu River. A surface of 17,000 ha would be flooded, accounting for around 17.5% of the total basin surface.

“…The Trebes-Negel River Basin, considered as representative by the Romanian Waters, is an important objective in hydrological terms, for the Carpathian area, being monitored since 1980 [1]. The water resource is intensely studied at an international level [2][3][4][5][6][7][8] and national [9][10][11]. The problem is the quality of the surface water [12][13][14][15][16][17], the minimum and maximum drainage at different times of the year [18][19][20][21][22][23][24][25][26][27][28][29][30][31] and at the same time on the water requirement in different climates [32][33][34].…”

This study aims to analyze the surface waters of the Trebes River. The Trebes-Negel River Basin is also known as the representative basin and it is the right tributary of the Bistrita River. The monitoring of this river reflects in a database necessary for the analysis of the long-term tendency of the hydrological regime, both in natural conditions and influenced by anthropogenic activities. The contact area between the Eastern Sub-Carpathians, in their middle part, and the Central Moldavian Plateau present a series of morphological peculiarities determined by a corrugated and varied structure, by an alternation of tough hard rocks and the action of the flowing water. These morphohydrographic peculiarities corroborated with climatic conditions dependent on the latitude, orientation and altitude of the major relief forms are determinant for genesis and flow regime. The first advantage in studying small river basins is that the results can be extrapolated for larger basins. Also, the magnitude of the analyzed data is smaller. The results of this study can certainly provide important information and can contribute to the implementation of effective measures in order to protect and prevent floods. The results of this study play an important role in the elaboration of hydrological prognosis of immediate or long-term utility because it is necessary to know in detail the variability in time and space of some hydrological parameters. The current period is characterized by an economic distinguished soar that requests for increasingly more water as a component of technological processes or as an indispensable part of sanitation for large human agglomerations.
