ECONOMIC EFFICIENCY OF FIVE SLOPE CONTROL METHODS USED TO STABILIZE AND DECORATE ERODED SLOPES

In the last years there is an increasing land surface that suffer degradation processes due to different types of erosion. Studies showed that there are a lot of classic and modern methods used for erosion control of the areas, but the cost-efficient of the implementation process it differs depending on many factors. The aim of the research was to study the economic efficiency of 5 alternative technologies used to stabilize a 100 m2 degraded slope with a gradient of 35%. The results showed that the variant of using biodegradable net is the most advantageous method, however for a pleasant and aesthetic appearance that integrates into rural or urban landscape it is recommended the use of specific ornamental shrubs

URBAN REGENERATION PROPOSAL OF A POST-INDUSTRIAL SITE IN BRAȘOV

The industrialization and especially the deindustrialization, have an impact on the current urban landscape, through the process of dismantling some industrial giants and the destruction or abandonment of those areas of land on which they once operated. The effects of these phenomena are fully felt in România and unfortunately there is still no well-established, professional plan for urban regeneration. The process of urban regeneration represents the adaptation to the present by rethinking the respective spaces in order to change their functions and aesthetics, considering that they have become unused spaces and even avoided by the population. Urban regeneration increases the quality of life and living conditions of areas adjacent to derelict sites and their reintegration into the urban environment, they generally become public spaces for leisure, entertainment, sports and why not, an oasis of greenery, created through proposed vegetation. Brașov is an example of a city with potential, but it lacks, for now, the official initiative and precisely because of this a plan is proposed to transform the former Hidromecanica industrial site into a place of aesthetic and functional relaxation, especially since the city of Brașov is a tourist town and the site is in its center

THE INFLUENCE OF TECHNOLOGY ELEMENTS ON SODIUM, CALCIUM AND MAGNESIUM CONTENT, AT THE MINT CULTURE, IN CONDITIONS OF SOMEŞENI - CLUJ AREA

The present paper presents part of the results of the researches carried out within the "Exploitation of systems for land improvement and crop irrigation" specialization at the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. The research underlying this paper was to determine the influence of some technological factors - irrigation, fertilization and biological material on the content of three important mineral elements - sodium, calcium and magnesium, at the mint culture, under the specific conditions of Someseni area - Cluj. The technological factors studied were: the irrigation regime, the degree of fertilization and the biological material, being tested three varieties of mint grown in culture in Transylvania, M. x piperita var. piperita "Swiss Mint", M. spicata L. var. crispa "Morroccan" and M. suaveolens var. "Apple Mint"

SOIL COMPACTION IN URBAN AREAS DEPENDING ON LAND USE: CASE STUDY IN CLUJ-NAPOCA, ROMANIA

Water infiltration in the soil is restricted in the urban area by the large impervious surfaces and the soil compaction. We conducted the experiments to determine if the urban soils are subject to accentuated compaction even in the permeable areas and if necessary implement is the bioretention systems to improve water and soil quality. We conducted the experiments under the same conditions of soil moisture for all the sites (four sites - different in terms of land use: industrial, low-density residential, high-density residential and commercial). Degree of compaction was determined with a digital electronic cone penetrometer. We established nine penetration points were for each site. In order to determine the degree of compaction we calculated the percentage of values that exceeded 2086.5 kPa (300 psi) in the first 45 cm. The results defined soils as slightly compacted - uncompacted in the commercial area; slightly compacted in the high-density residential area; moderately compacted in the low-density residential area; severely compacted in the industrial area. We concluded that compaction affects the soils regardless of the land use in urban areas
