Jednym z podstawowych działań zmierzających do zapewnienia bezpieczeństwa i ekonomiczności ruchu lotniczego jest zarządzanie przepływem. Ustanowiona w tym celu służba FMP nakłada na ruch regulacje po przekroczeniu granicznych wartości wielkości ruchu. Celem niniejszej pracy jest sprawdzenie czy istnieje możliwość wykorzystania w tym celu pojęcia płynności ruchu zamiast jego wielkości. Przeprowadzono pomiary i analizę zajętości kontrolerów ruchu lotniczego w czasie obsługi rzeczywistego ruchu. Jednocześnie rejestrowano rzeczywistą wielkość i płynność ruchu. W wyniku stwierdzono istnienie zależności między płynnością ruchu a zajętością kontrolera, a także pewne niedogodności podczas operacyjnego wykorzystywania wielkości ruchu przez służbę FMP. W rezultacie prowadzi to do wniosku o możliwości zastosowania zmodyfikowanej metody szacowania płynności do operacyjnego zarządzania przepływem ruchu lotniczego.

One of the primary measures to ensure the safety and economy of air traffic is the traffic flow management. FMP service was established for this purpose. It imposes regulations on the traffic if it exceeds the volume treated as a limit. The aim of this study is to check whether it is possible to use for this purpose the concept of the traffic smoothness instead of the traffic volume. The measurements and analysis of air traffic controllers occupancy during handling real traffic were carried out. At the same time we have recorded the actual traffic volume and traffic smoothness. As a result, we have found a relationship between the traffic smoothness and controller’s occupancy, as well as some inconvenience during operational use of the traffic volume in FMP's activity. As a result, this leads to the conclusion about the possibility of using the modified method of estimating the smoothness to operational air traffic flow management.

To study the shallow geological structure the Refraction Microtremor (ReMi) method was applied. This technique uses seismic noise analysis where a source of this small vibrations is the human activity e.g.: traffic, production, factories. The surveys were carried out in selected urban areas in the region of the Upper Silesian Industrial District: Sosnowiec–Pogoń , Chorzów–Chorzów Stary and Bytom–Karb. Each area is characterized by the presence of nearby roads with a very high traffic. The results of passive seismic (ReMi) were confronted with data obtained using Multichannel Analysis of Surface Waves (MASW) and resistivity imaging (RI). Seismic surveys were performed by apparatus PASI with 24 channels using geophones of 4.5Hz. The results showed that passive seismic can be satisfactorily used in such urban conditions. The shallow geological structure interpreted by seismic methods have been well-correlated with resistivity studies.

Interpretation of resistivity cross sections may be in many cases unreliable due to the presence of artifacts left by the inversion process. One way to avoid erroneous conclusions about geological structure is creation of Depth of Investigation (DOI) index maps, which describe durability of prepared model with respect to variable parameters of inversion. To assess the usefulness of this interpretation methodology in resistivity imaging method over quaternary sediments, it has been used to one synthetic data set and three investigation sites. Two of the study areas were placed in the Upper Silesian Industrial District region: Bytom–Karb, Chorzów–Chorzów Stary; and one in the Southern Pomeranian Lake District across Piława River Valley. Basing on the available geological information the results show high utility of DOI index in analysis of received resistivity models, on which areas poorly constrained by data has been designated.

In this paper the Horizontal-to-Vertical Spectral Ratio (HVSR) method and seismic data were applied to evaluate the resonance frequency – thickness relation. The HVSR method was used to estimate the parameters of site effects: amplification and resonance frequency from seismic noise records. The seismic noise was generated by artificial source occurring in Upper Silesia Coal Basin (UBSC), Poland, such as: traffic, industry, coal plants etc. The survey points were located near the Faculty of Earth Sciences in Sosnowiec, Bytom and Chorzow. Based on Albarello’s statistical test the observed H/V maxima was confirmed or rejected. Resonance frequencies were compared with available thicknesses of soft layer obtained by seismic survey (Mendecki 2012). Finally, the estimated resonance frequency – thickness relation for UBSC area showed quite similar power function coefficients as those obtained by other authors.

The purpose of this work was to detect groundwater pollution and to identify the conditions of soil and groundwater near the Urbanowice landfill site using geoelectrical measurements. Presented measurements are preliminary results from tested site and are beginning of continuous monitoring. Contamination outflows detected by resistivity and IP technique show a good correlation with available hydrological data. Contamination plume were found in Eastern part of survey profil.
