The paper contains the results of classification of rivers and streams of the Republic of Moldova according to classic Strahler method. Mentioned method was applied to estimate the hierarchical rank of the stream segments situated in 50 pilot basins using modern GIS techniques and drainage network of the GIS for Water Resources of Moldova. It was estimated that the maximal order of segments is 7 specific for the Raut and Ialpug rivers. Overall, length of 1st order streams forms 50%, while that of 7th order streams - < 1%. Additionally, stream number and frequency as well as drainage density were calculated for pilot river basins.

The article briefly describes the fields of application of the theory of extreme values, including climatology. The data format and the analysis methods of the annual maxima and minima temperatures in Chisinau are presented. Free R software and the GUI in2extRemes graphical package are used. Estimating the parameters of the Generalized Extreme Value distribution and return levels vs return periods is done using the Maximum Likelihood Estimation (MLE) method.

With a total area of approximately 14,770 km2, which makes up 43.6% of the country's surface, DPBS DRB is characterized by modest water resources. Total surface water resources make up about 3.39 km3 / year (25.32% of the Republic of Moldova's water resources). In the multiannual leakage of both Prut and internal rivers from Prut - Nistru, several cycles with different leakage rates are recorded, a phenomenon probably influenced by the cyclicality of solar activity.

In the present work, the electromagnetic pollution caused by radiation of industrial frequency (50 Hz) was estimated in Orhei city. Five unfavorable loci were identified in residential areas of the city associated with noncompliance of the sanitary protection zone. Based the biotesting territory, it was found that the most sensitive morphophysiological traits of the test plant Polygonum aviculare L. are the length of the main stem and corolla coloring. It is observed that the greater transmission line voltage the longer of the main stem, and less the intensity of corolla color (from red to white).

The main purpose of this paper was to evaluate the climatic comfort and discomfort through one of the most representative bioclimatic indexes – thermo-hygrometric index (THI). The THI was calculated by using the monthly average of air temperature (°C) and relative air humidity (%). The data was obtained from 3 meteorological stations, for a period of 38 years (1980 – 2017). The recorded data at these three stations, represent each geographic region of the country (the north - Briceni, the centre - Chisinau and the south - Cahul) and were studied and presented in more details.

Aspectele educaționale in dezvoltarea ariei biosferei au fost discutate cu diferite autorități din regiune cât și cu representanții organizațiilor internaționale. Programele educaționale trebuie să se dezvolte in baza prevederilor Convențiior internaționale cu atragerea celor mai bune practici de management a ariilor biosferei și elaborării studiillor privind adaptarea la schimbările climatice, protecția biodiversității, dezvoltării sectoriale, atragerea investițiilor și dezvoltării sociale din regiune. Resultatele discuțiilor au fost propuse pentru includerea in agendele locale privind dezvoltarea sectorului educațional la toate nivelele.

The amount of organic substance, nutrients (nitrogen and phosphorus) from diffuse sources in the Răut Hydrographic Basin was evaluated. It was found that out of total nitrogen, 66% is produced by livestock, 29% is formed in human agglomerations, and 5% is nitrogen from household waste. Phosphorus is produced by livestock -46%, by agglomerations of -49% and by 5% of household waste. The spatial distribution of nutrients on small river basins is relatively uniform. The major risk for water bodies in the BHR not to achieve a "good environmental status", under the Water Framework Directive, is current land use, in particular the weight and management of agricultural land.

In the paper, after presenting the terraces identification methodology (field research, drilling data, fauna remains, cartographic materials, satellite images, and bibliographic sources), describes rock type structure and morphometric parameters of terraces and rivers beds levels in the area of the biggest hydrographic basin located between the Prut and Nistru rivers – the Raut river basin. They identified and described five Pleistocene terraces and two levels of the upper Pliocene age in the river’s valleys. A detailed rivers terraces levels analysis showed that fault and folded formations found in the sedimentary cover of Moldovan plate, together with hydrologic characteristics and basic level oscillations were part of the fluvial morphogenesis during Neogene and Pleistocene age.
