Laser systems are widely used for measuring the most important physical values with the highest accuracy. In particular, laser measuring systems are used to identify earthquake precursors in monitoring tidal rock fluctuations. In many cases, signals from laser measuring systems contain noises that need to be filtered out. The signal component in this case has the form of a harmonic oscillation, the frequency and phase of which change and these changes carry information about the measured quantity. This signal shou...

The patchwork of land is one of the major factors that have a negative impact on the organization and the level of agricultural production. Excessive fragmentation reduces the intensity of work and increases the costs of agricultural production, thus generating lower and lower incomes. In terms of the unfavorable geometry of the boundaries of plots, resulting from the considerable fragmentation of land, the land patchwork plot is also an obstacle to building a cadastral system in Poland. The geodesy tool for impro...

Pontus Euxinus, the Black Sea today, was since ancient time playground of human activities, of which the most important is the trading navigation, whose beginning coincides with the Greek colonization started in the 7th century BC. The colonies and settlements founded along the coast were connected in ancient time mainly by nautical trade routes running along the shores. The case study area is located in the shallow waters of the Black Sea, in front of the sandbank system that today separates the Razelm-Sinoie lac...

The flood regime in the Prut ? B?rlad catchments is characterised by short, high intensity floods in the majority of upland rivers. These upland rivers are often ephemeral ? dry during the hot, summer months and wet during the winter months. In lowland rivers, flooding is more prolonged, especially near confluences. Short, high intensity rainfall coupled with low infiltration on catchments lead to flash flooding in upland areas. Changing land use patterns during the last 15 ? 20 years are increasing the frequency ...

The property that influences the binding properties of slag is its hydraulicity. The term ?hydraulicity? is now used internationally to describe cements and other binders that set and harden as a result of chemical reactions with water and continue to harden even if subsequently placed under water. There are a few exceptions but these chemical reactions generally involve calcium, silica, and aluminum constituents that react with water to form a whole family of calcium silicate and calcium aluminate hydrates. The c...

In the area of the Erzgebirge Foothills (Krusne hory), research of flooded mine pits in terms of water regime and quality as well as their management and subsequent use has attracted great attention in recent years.

Mining exploitation in an underground mine is the main factor disturbing the balance within the rock mass. By removing the obtained raw material from the rock mass mining activity leads to changes in the broadly understood state of the natural environment. Extraction of the raw material ? hard coal with barren rocks is often associated with the need to undertake dewatering of the rock mass and discharging mine gases into the atmosphere. The process of extracting the raw material from the deposit and the accompanyi...

Mathematical determination of the course of the baseline is necessary to establish the external border of the territorial sea, which is the state border. Its determination mainly affects the defining of the range of sovereign rights of individual states. For Poland, the determination of the course of the territorial sea baseline can be considered in two main aspects: legal and measurement-related. This paper discusses the issue of preparing measurements of the baseline. It presents domestic and international regul...

Assurance of radiation and environmental safety of nuclear power plants (NPPs) implies development of an automated radiation monitoring system. In its turn, such a system presupposes that hydrological and meteorological monitoring should be arranged on the NPP site and in its vicinity. Monitoring is launched at pre-design stages of the NPP construction project, and continues during the construction, operation and decommissioning (dismantling) of the plant. The goal of the study is to generalize the results of hydr...

Modeling was carried out on the basis of hydrological data from the ?yna River (north-eastern Poland). The length of the river is 264 km, the average river slope is 1.2 ?, the catchment area is 7126 km2. Modeling was based on data on water flows and the amount of precipitation. Neural models were created in which the input data is the amount of rainfall and the output is the flow. The possessed data has been divided into two parts, one of which was used to teach and test ANN, and the other - smaller - to verify th...

Hydrological reclamations are one way of eliminating consequences of surface mining of coal. The residual quarries occupy extensive areas and the most effective way how to integrate them into the surrounding landscape is their flooding. This will create a new water area that can be used recreationally and could also serve as a habitat or a migration point for different plant and animal species. The contribution is focused on northern part of the Czech Republic (The Most Basin) where brown coal has been mined for n...

This paper presents the results of an experimental study of concrete designed as a secondary barrier for radioactive waste deposition. Sorption materials, such as natural zeolite, have very good encapsulation ability to certain ions, which can be harmful for the environment, such as 137Cs. Incorporation of natural zeolite into concrete may increase the protection ability of secondary barriers against radionuclide release. Determination of water-transport- and water vapour transport properties of such concrete can ...

Ice gouging is destructive mechanical impact of ice on the underlying ground surface associated with ice cover dynamics, ice hummocking (ridging) and formation of grounded hummocks (stamukhas) under the influence of hydrometeorological factors and coastal topography. Climate change and anthropogenic influence can cause changes in conditions of ice scour formation. Shallow freezing seas and big lakes are most vulnerable to such changes. Studying of the ice scours? parameters has a great economic and fundamental imp...

The basic rationale for the research was the lack of landscape planning approaches within the spatial planning process in Croatia. The most important deficiency addressed in this research was an integral inclusion of the public opinion and their values into the planning process. Dealing with the conflicts which may arise from it represents one of the activities that are taken into account within landscape planning. Shortage of an integrated approach to landscape planning in Croatia causes conflicts between differe...

The analysis of the correlations between the specified characters (29 characters) along with the analysis of the variety classification for different characters involved in drought tolerance can provide information on the possibility of using varieties noted for a certain character in improving the tolerance to drought of another variety, where that determination was detected as a selection indicator. The correlation between the stem length ratio to 20% PEG versus the control stem length after 15 days and the loss...

Modern ideas about the formation of hydrocarbon deposits are based on the results of experimental and theoretical studies of the lithosphere dynamics. They are based on the established facts of the "instability of fluid systems in the sedimentary cover and foundation, as well as the migration of fluids through the permeable zones resulting from the varying stresses in the earth's crust". It follows that the geological environment is non equilibrium. Forces of external influence and thermodynamic conditions inside ...

Coastal areas around the world are constantly subjected to pressure on human activities. The environment suffers transformations from the anthropogenic activities, transformations that most often have the effect the degradation of the environmental factors. Coastal areas are often described as areas of potential conflict between the stakeholders and mechanisms such as integrated the coastal zone management or, more specifically, marine spatial planning are designed to achieve the sustainable management in this are...
