In the recent years, the climate changes have determined the increase of the frequency of flood, and concurrently, negative effects of these weather phenomena were amplified by other factors (the deforestation, needs of the hydro technical works, etc.). Atmospheric precipitation contributes to formation of superficial runoff, or accumulates in the snow in the winter, sometimes participating during melting to form the maximum runoff. The consequences of this rainfall can be serious in terms of erosion and soil wash...

The aquatic systems of Kerch peninsula are unique groundwater manifestations situated on the area with a low technogenic pressure. Thereby these are very interesting object for the study of processes of the migration and accumulation of the geochemical markers (polycyclic aromatic hydrocarbons, PAHs) as the background areas. The study is devoted to the assessment of the processes on the geochemical barriers (GCB) ? self-organizing components of geochemical systems, where the activation of physical and chemical pro...

The Paper present confined groundwater flow and solute transport modeling in water catchments area and wastewater system Giarmata, using the hydraulically modelling whit mathematical simulation. Modeling purpose is to constitute extending pollution propagation of aquifers generated of possible wastewater pumping station pollution. Pollution zone definition is necessary to settle technical measures to using drinking water systems. The used software for numerical modelling in this paper is Processing Modflow for Win...

Nowadays, after periods of time without precipitation, more and more frequent rains are coming in with very high flows in very short time. In case of extreme precipitation phenomena, sewer networks can no longer take rainwater flows, which often occur with large damages, often with loss of life. Drinking water is not renewable. That is why it is important to protect drinking water sources by using rainwater more efficiently. By recovering, storing and using rainwater, costs are reduced by treating and transporting...

World is changing rapidly. We are facing new reality and challenges. New global and complex solutions are needed to adapt to future reality. Tasks about landscape are coming to the forward more and more. It is necessary to speak about role of landscape in our life. Many points of view need to take into account when we want to speak about landscape and changes which are waiting for us in next decades. Question for researchers is how to obtain the best data for the best suggestions and recommendations for policy mak...

In the present paper, we present a part of the results of the questionnaire survey, which took place in the municipalities of 93 municipalities in the Presov region. The questionnaire contained 27 questions which, in addition to formal information on the municipality are focused on the occurrence and periodicity of floods, the time axis of the floods, the current state of preparedness of municipalities for floods, as well as the improvement/ worsening of the situation in the case of applied flood protection measur...

The effects of global warming are becoming more and more felt by changing climatic conditions across the entire surface of the earth. Thus, in some regions of the Earth's surface, catastrophic floods have begun to occur more and more often due to the increase in both the occurrence frequency and the intensity of torrential rains. In order to reduce the flood damage, it is necessary to prepare hazard maps and flood risk maps. These maps are prepared using hydraulic simulation of the flood propagation on the waterco...

The main objective of this paper was to assess the water quality in Siret, in the Galati area. Galati is a port town on the Danube River in south-eastern of Romania. For the purpose of carrying out these studies, water samples from ten Siret sites were taken. Water quality has been monitored between November 2016 and December 2017. Physical and chemical characteristics of water were performed. The PFP7 Flam Photometer was used for potassium and calcium ions determination. An UV-VIS Specord 210 Spectrophotometer wa...

The application of reactive materials in the form of a Deep Permeable Reactive Barrier during and after coal conversion constitutes an innovative concept of protecting the environment from georeactor influence. The reactive materials filling the post-process cavern will make it possible to remove or immobilise the gaseous and liquid contaminants that may be subject to leaching, while also reinforcing rock mass stability. The article pays particular attention to the technical and legal possibilities for reactive ma...

The mouth areas of the seas are the most interesting and complex objects for studying the distribution of pollutant flows and the factors of their formation. Different approaches can be used to identify pollutant flows and the role of the geochemical barriers, in particular the analysis of the distribution of marker compounds that most clearly reflect the pollution levels themselves and possible sources of their entry into the components of the aquatic systems. Polycyclic aromatic hydrocarbons (PAHs) are considere...
