Global deterioration of surface water quality was attributed to a pair of factors: human activities and natural processes, including hydrological variability, climate change, weather characteristics, and adjacent land use. The study of water quality in the contemporary era is a current issue. This paper presents an analysis of the variability of water quality parameters in a study developed on 4 years. In a number of 5 monitoring points, 18 water status parameters were monitored. Primary statistic methods were use...

At present, the monitoring of forest areas is a national requirement. The importance of protecting forests in mitigating climate change is well known. On the other hand, the economic aspects involving the efficiency of forest management imply correlation with the growing demand for wood on the market. From this point of view, the inventory and the evaluation of the rate of growth and yield of forest areas is extremely important. Estimating the growth rate per unit of hectare and the level of production of wooded a...

Estimating the growth level per unit of hectare and the level of production of wooded areas for accurate obtaining and portfolio is significant in determining the supply of wood for an efficient management system. The present paper is based on the evaluation of six growth seasons locust tree (Robinia pseudoacacia). The monitored sectors are located in the eastern part of the Romania. The climatic gradient can also be neglected due to the nature of the studied areas. The timeframe in which the study was conducted r...
