On the basis of provided data from Slovak Hydrometeorlogical Institute were realized the calculation of rain factor for each rain-guage stations. Because provided data were in digital form, we proceeded to digital processing in graphical environment of Microsoft Excel i.e. each minutes of chosen rain were considered for separate rain division. Calculated data were compared with published values of Soil Science and Conservation Research Institute (SSCRI) and also with Methodology for implementation of research results into agricultural practise. From calculated values were created also the lines of exceedance of probability, which give detail information about occurrence of calculated values of rain factor once per 100, 50, 20, 10, 5 and 1 year. Also there were compared the different methodologies of rain factor calculation and kinetic energy of rain and their influence on final values. From calculated values there were found out that on all examined localities are our calculated values several times higher than in listed publications. These differences can be caused by different methods of data processing but also by number of processed years, because values of rain factor in listed publication were calculated for lower number of years. According to calculated values were created the redistribution of rain factor values on particular months of vegetation periods and it was found out that the highest percentage fall on summer months (June, July, August) and on the other hand, the lowest percentage, on the months April and October, therefore it is necessary to attach importance on soil erosion control especially in summer months. Comparison of different methods of data processing (digital vs. graphical) showed up, that differences in final values of rain factor by using of different methods of data processing are minimal, therefore it can be assumed that used methodology is right. Relations for kinetic energy calculation and different methodologies also significantly influenced final values of rain factor. Calculation of rain according different authors showed up that using relation for kinetic energy designed by Marshall, were obtained lower values, which influenced the final value of rain factor i.e. its final values was more closer to pu blished values. Comparison of Hudson (KE > 1) and Wischmeier and Smith methodology it was found out that with using Hudson methodology is final value of rain factor almost two times lower than with using Wischmeier and Smith methodology. It was also done the calculations of rain factor which take into account the lack of data. There were used the relations according different authors. These relations calculate only with annual precipitation. The results showed that final values of rain factor is several time higher than with using equations for example of Wischmeier and Smith.

In recent years, there is already not achieved in Poland the acceptable costeffectiveness ratio of the construction of collecting systems and the rate of sewerage (collective and individual systems) is still low, especially in the countryside. Therefore it seems to be necessary to supplement the networks (sewerage) systems by individual treatment plants. In the article the choice of four variants of on-site wastewater treatment plant with soil absorption system using AHP analysis was presented and analysed. It has been shown that this method can be successfully used to select the variant of onsite wastewater treatment plant with soil absorption system. It should be taken into consideration which of two sub-criteria: system and receiver is a priority. It is also possible that both sub-criteria are equivalent. In the case of equivalent importance of system and receiver, domestic wastewater treatment plant with a pressurized soil absorption system was the most favourable, and the least favourable – septic tank with soil absorption system. In the variant of a “system” priority, domestic wastewater treatment plant with a pressurized soil absorption system prevailed over other variants but so little that from practical point of view also variants of septic tank with pressure and classic (gravitational) soil absorption system may be chosen. In the case of environmental factors priority a domestic wastewater treatment plant with a pressurized soil absorption system should be considered as the best one. The analyses carried based on certain attribute values confirmed earlier opinions on the important role of decision-makers’ experience or the usefulness of average values obtained from the analysis performed by several people.

The article presents the analysis of influence of river bed shading by the trees and bushes on flow conditions on the selected section of the Wełna River. The research area were selected as the lying mutually adjacently sections of the river (one in a small grove, and the second in the open field without of trees and shrubs). The flow rate and velocity distributions were determined in the cross sections based on of field measurements. Additionally, there were measured the decrease in water tableand grain size curves developed. The LAI index were measuredin the grove and the number and macrophytesspecies composition was described in the investigated cross sections. Based on the results, the impact of river bed shading by plant community were determined due to the shaping the geometry and flow resistance in the riverbed.

Nowadays households often decide on running a tourist business which can become a source of additional income or a way of self-employment. The number of tourist farms and other tourist businesses are constantly growing in response to the increasing interest in ecotourism and agritourism. Farm owners are fully aware of the role the internet plays not only in the effective promotion of their businesses but also booking their services online. As a result, more and more farmers choose an IT firm and commission the design of their website. The aim of the article was to examine the market of website design services in Poland. The survey concerning the creation and promotion of tourist farm websites was conducted as well as the analysis of costs and conditions offered by the IT service providers.

Information technology provides a large number of tools and techniques that can be used to create interactive location maps of spatial objects. The article presents the use of Microsoft Bing Maps and jQuery JavaScript, as an alternative to Google Maps. The study was based on web application tests. Applications were prepared according to different design assumptions and present selected ponds near Kraków. Test results shows that users expect lots of functionality, personalization map view, interactivity and dynamic presentation of the content.

There is an increasing number of Internet applications which shows graphic representation of selected aspects of the Earth’s surface. On the Internet can be find various types of interactive and dynamic maps. The Internet has redefined how maps are used. Maps on the Internet are more interactive, for example provides directions and satellite or aerial imagery of many countries. Most of the mapping platforms usually provides a set of multiple APIs (Application Programming Interface) including an AJAX control, static maps, REST Services or Spatial Data Services, to incorporate the latest maps, imagery and location services in web applications. The main topic of this research is to show that raster maps are still in use today and have lots of advantages. The aim of this research is to characterize and comparative analysis of selected programming techniques, especially creating a static maps of spatial objects using query string parameters.

Time of contamination in the surface of the earth is important information under the legal aspect. This parameter is often determined by the ability to demonstrate the relationship between the type of activity of the company, and result, in the form of pollution. Depending on when the event occurred and who was responsible, pollution can be considered for damage in the surface of the earth or historical pollution. Taking into account the properties of phenol, which is a substance present in the environment both in its natural state, and an important intermediate in the chemical industry, in this paper the opportunity of determination of the time of contamination in the surface of the earth was calculated based on knowledge of the half decay. In the authors opinion the results presented in the diagrams, allow to estimate the time of creation of contamination. The results of calculations confirm that, given the relatively rapid biodegradability analyze, measuring its concentration for soils types B and C should be a maximum time limit done respectively to 170 and to 90 days after the occurrence of pollution. The results of analyzes also indicate that the areas used industrially measurement of the concentration of phenol made in after 90 days (assuming a 10 day time decay) and sometimes even 20 days (assuming a 2 day time decay) since pollution is not justified. According to the authors, the knowledge of the above facts can be crucial in the selection of measurement parameters and for determining the entity responsible for the pollution of the earth’s surface, e.g. phenol.

The paper presents an analysis of water consumption in the period of 2000–2012 in rural households in 8 villages of the Brzesko municipality. They are inhabited by about 17 thousand people, of whom 81.6% use tap water. An increase in water consumption was recorded in all villages and it ranged from 1.2 to 240.2%. Depending on the locality, the mean water consumption per capita ranged within 30.9–70.5 dm3 · PM–1 · d–1, whereas the mean amount in the multi-year period for all villages was 46.7 dm3 · PM–1 · d–1. Depending on the village, water consumption per a single household connection ranged within 137.6–293.7 dm3 · conn–1 · d–1. Mean amount for all localities was 197.7 dm3 · conn–1 · d–1. The maximum water consumption was recorded in the village where the water supply network was constructed the earliest, while the minimum – in the village where the network was built at the latest. The correlation of mean unit water consumption with the number of years of tap water usage reaches the value of 92.6%. On the other hand, in the case of the relationship of this ratio with the distance of the village from the district town, the correlation was 69.7%.

The paper analyzes several classical formulas for calculating the beginning of bedload transport, taking into account recent survey of Polish scientists conducted in the field: Egiazaroff formula [Michalik 1990], Wang formula [Michalik 1990], Bartnik formula [1992] and Diplas modified by Michalik formula [1990, 1999]. The analysis is intended to help in the bedload transport incipient motion calculation and interpretation of the results of the bedload transport in mountain streams. An example of calculation of parameters for entraintment of sediment in selected catchment of a mountain stream, in two areas, is included.

Along the paper we used spatial characteristics of land water resources using cultural landscape philosophy. The study was done for the Msciwojów water reservoir area in Sudety mountains in Poland. Some chosen GIS methodology, in our case Arc Hydro Tools 9.0 was used to run the analyze. Along the study we concentrated on tho rivers and two catchments: the Wierzbiak and the Kałużnik rivers. Topographic Topographic Wetness Index (TWI) was used to show of spatial distribution of water resources. We found that highest values of TWI are located at the bottom of river valleys and along slopes of land and in concave forms of areas. At the same time lowest values of TWI are occurred in an areas which are adjacent to the convex forms.

Syr Darya one of the most important rivers in Central Asia, Central Asia’s longest river, and second-largest by volume. By the time it nears the end of a twisting course that takes it through four Central Asian states, the Syr Darya has accumulated such high levels of agricultural runoff such as pesticides and fertilizers, industrial waste, and any number of other contaminants that some are warning that crops irrigated by the river in southern Kyzyl-Orda province should be burned.

The review of literature related to tests of shear strength of municipal solid wastes is presented in the first part of the paper. It was revealed that MSW have very various values of angle of internal friction and cohesion, which are depended from composition of wastes, degree of biodegradation, test methods (type of tests, range of strain). It was stated, that the influence of aforementioned factors is often unclear, what causes that the choice of shear strength parameters of MSW for slope stability analysis is complicated. Slope stability analysis of examplary sanitary landfill in Chełmek is presented in the second part of paper. The shear strength parameters of wastes were taken from the first of paper. It was revealed that typical slope stability calculations gave high value of safety factor, whereas probability analysis show that expected performance level of sanitary landfill is between poor and below average.

Geotechnical parameters of slope cover soils originated from valley of Siarki stream located in environs of Siary and Owczary (Beskid Niski Mts.), where in June of 2010 were observed shallow landslides, are presented in the paper. Tests results revealed that tested soils can be described as clayey silts with sand and grains of gravel fraction. It was stated that the soils are well compactable according to requirements for material used for road embankments. On the other hand, tests revealed that the soils are sensitive to changes of moisture content, especially in case of bearing capacity and shear strength parameters, mainly cohesion values. It was found that the analyzed soils can be a good base of road pavement in dry site or if they isolated from the influence of ground water.
