As a result of the reduction of the number of hydrological gauge stations, on the basis of which natural and disponible water resources can be assessed, it is proposed to assess them by identifying climate runoff. The obtained results allow the forecast of the changes of the water resources in the conditions of the environmental changes. Climate runoff is essentially determined as a difference between annual precipitation and evaporation, which depends on the geographical position and the orographic specificity of the studied territory. It is logical that they are subject of geographical zoning. In the paper are evaluated the climatic water resources based on whi ch the natural and disponible ones from the Răut river basin were calculated.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ROSCI0076 Dealul Mare- Hîrlău site represents the largest protected area from Moldova’s Plateau where forest habitats occupy a majority surface. A total number of 10 Natura 2000 forest habitats were identified on the site’s surface. Among them, the majority are 91Y0 - Dacian oak hornbeam forests and 9130 - Asperulo-Fagetum beech forests. These are comprised of 79% natural forests, while planted forests represent 19%. The main age ranges between 40 and 80 years, with compact areas with young forests, as well as with forests older than 100 years. Forest habitats are stable from an ecological point of view, ensuring optimum conditions for the development and colonization of species presented on the site’s map.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

India generates about 12 million tonnes of SPM annually and hence, needs effective management. The present study delves into the use of SPM as a ternary blend in cement-lime stabilization of an expansive soil. An expansive soil was stabilized using a combination of 4.5% lime (determined from the Eades and Grim pH test) and a fixed cement content of 1%. The effect of the stabilization was studied by casting cylindrical specimens of dimensions 38 mm x 76 mm and curing them for periods of 7, 14 and 28 days. This process was modified by blending it with SPM as a ternary additive up to 5% in increments of 1%. The optimal dosage of SPM was evaluated for enhanced strength gain which was then subjected to a wet-dry cycle to understand the effect of variation in moisture content. The results of the investigation revealed that cement-lime stabilization of the soil was significantly better than lime stabilization alone. 1% SPM was found to be the optimal dosage required for maximum strength gain. Based on the results, it was concluded that ternary blending of SPM can potentially be beneficial in soil stabilization.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"14 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Globally, landslides represent the geomorphologic hazard that produces the greatest damages, the losses being both economic and human. In Romania, the damages caused by landslides are, in most cases, economic. This study was developed because the mountainous area of Neamț county is one of the most susceptible to landslides areas, Bistrița Val ley from Borca and up to the area of Piatra- Neamț Municipality being very affected by this type of erosion. One of the reasons this study was developed is the lack of landslide susceptibility maps for the left side of the Izvorul Muntelui Lake bank, the only official maps being drawn up at county level, a too coarse approach for studying the susceptibility to landslides in a more detailed way. This study was carried out using the maximum entropy method, eleven landslide causal factors, two geomorphometric variables obtained by combining several geomorphometric derivates and the existing landslides position data that occurred over the past 15 years. A very conclusive result of this study is the very high impact of the National Road 15 and the high slope deforested areas on the onset of the landslides and the statistical modeling of the susceptibility.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70910713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It presents a danger for aquatic biological diversity in concentrations from 0,03 to 2,00 mg/dm 3 NH 3 depending on the species and age. This conditions also are specified in Chapter II (Specific substances to be introduced into surface waters, pt. 8) of the Republic of Moldova Government Decision no. 802 of October 9, 2013. The study includes evaluation of non-ionized ammonia in the water of some portions of the Dniester and Prut river tributaries, which crosses the Central Development Region of the Republic of Moldova. In the rivers R ă ut (upstream of B ă l ț i town and downstream of Varvareuca village), Ciulucul Mare, Ciulucul Mic, Camenca (Gura Camencii village) the ammonia concentration in different years (1981-2019) was low, but in the R ă ut river water, downstream of the Orhei town at 5 O C was of 0,029-0,35 mg/dm 3 and at 15 O C - 0,065-0,528 mg/dm 3 . The calculation of the NH 3 content in the water from the left tributaries of the Prut river that crosses the Central Development Region of the Republic of Moldova at a temperature of 5 O C and 15 O C shows high values in the water of the Gârla Mare river, Medeleni and Catranâc villages (0,394-0,818 mg/dm 3 ), river Gârla Mic ă , liman (0,141-0,327 mg/dm 3 ), Delia river, Pârli ț a village (0,84-1,78 mg/dm 3 ), Nârnova river, Nisporeni town and Leu ș eni village (0,27-0,73 mg/dm 3 ), L ă pusna river, Voinescu village (0,277-0,65 mg/dm 3 ). Thus, in the water of different years (1981-2019) on many portions of the Dniester and Prut rivers tributaries, which crosses the Central Development Region of the Republic of Moldova, the concentration of ammonium (NH 3 + NH 4+ ) was high, and depending on the pH and temperature the calculated non-ionized ammonia content exceeded the value of 0,025 mg/dm 3 .","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, the purpose of the research is the mapping of the grasslands of Arad county and their analysis in correlation with the altitude and slope of the terrain. For Arad county, the grassland areas were identified and mapped, as follows: the Corine Land Cover database, 2018 edition, on a medium scale, was completed on the basis of orthophotoplans and cadastral plans at a scale of 1:10000, a process that obtained representation of grasslands on a large scale. The calculations show that 12% of the area of Arad county belongs to grasslands. The overlay analysis allowed the study of grasslands in correlation with other environmental factors, which can influence the floristic composition or their spatio-temporal dynamics. Thus, 89% of the grassland areas are located between 80.8 and 300 m altitude and 96% are located on slopes with an inclination below 15º. The application of GIS techniques in the research of grasslands in a given territory, offers the possibility of a holistic approach or for particular cases.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The territory of the country (including the Transnistrian region), from the point of view of the administrative-territorial structure, is made up of 983 units. Thus, the analysis of eroded lands was carried out on administrative units at the level of villages, communes and cities, according to the data of the 2021 year from the Land Cadastre, developed by the Agency for Land Relations and Cadastre of the Republic of Moldova . The created database was later imported into a GIS (Geographical Information Systems) program and processed using ArcGIS software. The mapping and classification of the data regarding the proportion of eroded agricultural land (total; strongly, moderately and weakly eroded) allowed the identification of the most vulnerable areas to these processes - the Central Moldavian Plateau (Codrilor), the Ciuluc Hills, the Dniester Plateau etc. The frequency rate of agricultural land in total per country was 73.7%, including arable land constituted 54.9%. Of the entire agricultural area, 73.2% was monitored from the point of view of soil and geomorphological processes: approximately 1/3 of all agricultural land is affected by some degree of erosion, including 4.5% that are heavily eroded. The specific factors of soil erosion and the main consequences are evaluated, with an emphasis on the most affected regions.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70912386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Prut-Dniester interfluve, the ecological condition of rural geosystems can be assessed as moderately favorable and low-favorable. Bukovynian Subcarpathians, in the middle part of Northern Bukovyna, are distinguished by favorable ecological conditions for both human life and rural tourism. The predominance of the leaching soil water regime of geosystems (sufficient rainfall) and notable wooded areas contributed to the sanitation of these landscapes from various artificial pollutions. The Carpathian subregion is the most distinct and unusual in terms of geoecological evaluation. There is a more complex set of natural conditions (vertical differentiation of landscape complexes). Fluvial terrace landscape complexes (with a chain or mosaic-scattered settlements) have highly favorable ecological and geochemical conditions. This subregion is the most optimal regarding the recreational and tourist trend. Among the geoecological factors of its development, it is worth noting the high quality of groundwater (drinking water), which, despite the excess precipitation, is sufficiently saturated with biologically essential macro- and micronutrients and have mostly medium hardness (Ca + Mg) and mineralization.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70910351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
