Our paper describes a case study, on a 27 km-long section of the Moldova River in Romania, on which floods often occur. Floods are some of the most disastrous phenomena caused by combined factors: atmospheric and hydrological with significant repercussions on the environment, with great material damage and loss of life. According to this application, GIS technology is a remarkable solution that can solve rationally, intelligently and efficiently the increasingly difficult problems related to these phenomena, to th...

Our research reveals the importance of GIS technology for land evaluation. The research was conducted on a piece of land of about 770 ha in Romania, which enjoys a diversity of natural factors. Land suitability evaluation, especially given limited land resources, is an important stage in the assessment of its ecological state and for land use planning. The main goal of this evaluation is to estimate the possibilities of maintaining the optimal natural potential of the soil in the process of a certain mode of use o...

This paper tackles a research concerning the restoration for agricultural purposes of different soils affected by landslide phenomena. Landslide is an erosion process which adversely affects the relief, and the damage caused to life and to the environment as a whole are considerable. Nevertheless, soils are the most seriously affected by landslide, as they lose a vital characteristic: their fertility. Research has been conducted on several experimental fields, set up on different types of non-evolved soil, in orde...

This paper studies a hydrographical space with an area of approx. 20,000 km2, located in the NE of Romania. The main objective of the study is to identify and delimit the water bodies (hydrographic microbazins) within the Prut hydrographic basin. This aspect is very important, in order to determine their status, establish future objectives regarding water management and improve or maintain a certain existing status. The methodologies developed by A.N. Apele Rom?ne Bucharest were used for the classification and del...

The purpose of this paper is to analyze the negative effects of surface leakage through soil erosion in a hydrographic basin. The analysis, in the context of a phenomenological methodology of erosion, involves the detailed knowledge of the agents, factors and interaction mechanisms. Thus, a multitude of mathematical models have been launched, in order to model this natural phenomenon. In this paper, an analysis of sheet erosion is performed, both in situ and through erosion modeling. This was carried out, by using...

This paper presents a case study regarding the GIS applications on the slopes with frequent erosion processes in depth. Monitoring the gullies consists in identifying them in the land, their positioning on the map, their classification and recording according to several indicators and following their evolution in time. The study is carried out in a water catchment area of 4,665 ha in Berheci Superior, Bacau county, Romania. By using ortophoplanes, satellite images or air-photograms (in some cases) and the document...
