Opis:
The city of Algiers (Algeria) is a highly seismic area, and therefore, soil liquefaction poses a major concern for structures resting on sandy soil. A campaign of 62 static penetration tests or cone penetrometer tests (CPT) was carried out on a site located in the commune of Dar El Beïda in Algiers. The soil Liquefaction Potential Index (LPI) values were assessed, for each borehole, based on the simplified procedure of Seed and Idriss. On the other hand, the geographic information system and geostatistical analysis were used to quantify the risk of soil liquefaction at the studied site. It is worth mentioning that the (LPI) was taken as a regionalized variable. In addition, the experimental variogram was modeled on the basis of a spherical model. Also, the interpolation of the LPI values in the unsampled locations was performed by the Kriging technique using both isotropic and anisotropic models. Kriging standard deviation maps were produced for both cases. The cross-validation showed that the anisotropic model exhibited a better fit for the interpolation of the values of the soil liquefaction potential. The results obtained indicated that a significant part of the soil is liable to liquefy, in particular in the northwestern region of the study area. The findings suggest that there is a proportional relationship between the risk of liquefaction and the increase or decrease in seismic acceleration.

Opis:
According to the Helsinki Commission report from 1994 around 15000 tonnes of chemical warfare agents were dumped to the Baltic Sea after World War II as part of the demilitarization process of the former Nazi Germany. Continuing corrosion of metal encasements makes the dumped munitions a ticking time-bomb, which could potentially harm the whole Baltic Basin. The presented work addresses important aspects for a proper evaluation of the threat; side scan sonar survey data storage and analysis of a spatial distribution of the sonar targets potentially related to chemical weapons. The chosen software environment was GIS oriented. ESRI ArcGIS built-in tools were used to determine the hotspots of the targets on the official post-war munitions dumping sites; Gotland Deep and Bornholm Deep. The automation process of mapping in GIS was also proposed. Therefore, a holistic approach for digital mapping of the sonar targets related to dumped munitions was created.

Opis:
Dryland farming, managed intensively, with the input of chemical fertilizers exceeding the dose threshold, can cause soil degradation. Degraded soil affects low environmental carrying capacity and soil and water conservation. Researchers conduct soil tests on agricultural land to address this issue, especially those that apply a continuous cropping system. This study aimed to examine soil properties to determine the conditions of soil degradation in dryland farming. The method integrates spatial analysis with Geographic Information Systems (GIS), field surveys, and laboratory soil samples analysis. The spatial data used to map the potential for soil degradation includes land use, slope, rainfall, and soil type. Integrating spatial and laboratory data, such as soil physical, chemical, and biological properties results in soil degradation status conditions representing the actual conditions in the field. This study found that there were three classes of soil degradation successively, namely mild, moderate, and high. There are two statuses of soil degradation, including non-degraded and light soil degradation status. The soils with a mild degree of degradation are due to the limiting factors of permeability, fractional composition, and total porosity. Some actions that can be taken include planning soil degradation prevention measures by utilizing soil degradation potential maps that have been made for areas with high soil degradation potential. For the sites with a status of soil degradation, efforts are made to start carrying out soil improvement actions in accordance with conservation principles to reduce the soil degradation that occurs. Moreover, organic matter is added to degraded and potentially degraded soils to increase the stability of soil aggregates and water-carrying capacity.

Opis:
Maritime and port areas throughout the world are exposed to many different hazards, like pollution, terrorism and natural disasters. Early detection, identification and preparation of appropriate response strategies is especially important in the case of semi-enclosed basins like the Baltic Sea, mainly due to the marine ecosystems' continuous absorption of pollutants including oil, heavy metals and chemicals. Many of those agents are characterised by great toxicity and cause devastation of the natural environment. The huge development in the information technology provides the means and possibilities for much faster and more efficient access to survey data, allowing their remote, nearly real-time management, processing and visualisation. Several approaches and techniques of measurements are available in marine environment monitoring. These consist of direct sampling, airborne and satellite imagery, hydrological measurements using CTD probes, remote sensing with the use of electromagnetic waves, acoustic methods based on the data acquired by multibeam systems, side-scan sonars and singlebeam echosounders.

Opis:
The article aims to show the possible use of geographic information system (GIS) and GIS software, namely various types of GIS analyses, in the uniformed public services. Such software enables the collection of spatial data that can then be associated with tabular information, the form in which data is stored by uniformed services. Using the collected data, public officials may perform different GIS analyses and visualize statistical data in the form of clear thematic maps. This allows, for example, to visualize and locate the number of road accidents or crimes. Thanks to such solutions, uniformed services could gather a consistent amount of information and therefore improve the quality of their work and insure more effective security, all for the benefit of society. The geographical information system should find a wider application within Polish public services.

Opis:
The purpose of the present study was to compare the prediction performances of three statistical methods, namely, information value (IV), weight of evidence (WoE) and frequency ratio (FR), for landslide susceptibility mapping (LSM) at the east of Constantine region. A detailed landslide inventory of the study area with a total of 81 landslide locations was compiled from aerial photographs, satellite images and field surveys. This landslide inventory was randomly split into a testing dataset (70%) for training the models, and the remaining (30%) was used for validation purpose. Nine landslide-related factors such as slope gradient, slope aspect, elevation, distance to streams, lithology, distance to lineaments, precipitation, Normalized Difference Vegetation Index (NDVI) and stream density were used in the landslide susceptibility analyses. The inventory was adopted to analyse the spatial relationship between these landslide factors and landslide occurrences. Based on IV, WoE and FR approaches, three landslide susceptibility zonation maps were categorized, namely, “very high, high, moderate, low, and very low”. The results were compared and validated by computing area under the receiver operating characteristic (ROC) curve (AUC). From the statistics, it is noted that prediction scores of the FR, IV and WoE models are relatively similar with 73.32%, 73.95% and 79.07%, respectively. However, the map, obtained using the WoE technique, was experienced to be more suitable for the study area. Based on the results, the produced LSM can serve as a reference for planning and decision-making regarding the general use of the land.

Opis:
In the 21st century, at constant economic and industrial development, the efficient and fast management of technical infrastructure is a key element. Its quality and technical condition considerably influence rural development, possibilities to acquire capital, create new jobs, etc. One of the key issues is the road infrastructure, i.e., network of commune roads, and its condition, while the possibility of management and promptness of decision making determine and are of key importance for planning further development of the commune.In order to manage the road network efficiently and fast, the commune needs all available relevant information. Data describing road technical parameters are the spatial data. Accumulation of the data in geographical database gives a general spatial picture of the commune road network. All data describing roads are recorded in so called road books. The obligation is imposed on the communes by the Minister of Infrastructure Regulation in the method of numbering and registration of public roads [Journal of Laws, No. 67, Items 582 and 583 of 25 April, 2005].The main objective of the presented paper was the realization of a geographical database of the parameters of road network for the Raciechowice Commune Authorities using GPS receiver and the MapSource and ArcView specialist computer packages. For this purpose geocoding of road sections and their spatial inventory in the Raciechowice commune was made by means of a GPS device. The results of measurements obtained by means of GPS were then read immediately to MapSource. The data obtained in this way allowed to create a database in which technical parameters of individual sections of the Raciechowice commune roads were recorded. The ArcView software was used for management of the spatial database and visualization of road technical parameters in form of maps and diagram maps.

Floods are a great concern for people and infrastructure, and this is an is‑sue which has increased in several regions around the globe in recent years. This study aims to evaluate flood risk areas and create a flood risk map using in‑tegrated remote sensing data and a geographic information system (GIS) in the Wasit governorate – eastern Iraq. Specifically, GIS‑based multi‑criteria analy‑sis (MCA) was used to map flood hazard areas using a four‑criteria layer which is as follows: flow accumulation, slope, rainfall, and elevation. These four layers are standardized and combined using the overlay approach in ArcGIS software and a final map was produced. The study area was divided into five zones based on the results map, namely: very low, low, medium, high, and very high, according to the flood risk area. The resulting map indicates that over 60% of the study area is likely to experience a high and very high level of propensity of flooding. This study could be useful for government planners and decision‑makers to predict potential flooding areas and enhance flood management plans.

GIS data processing techniques are currently being used to revise many ideas in the field of geomorphology and related scienc-es. The paper presents the characteristics of the landform relief of the Mroga and Mrożyca interfluvial area (on the northern margin zone of the Łódź Plateau) based on the results of GIS spatial analysis models. These are techniques that have not been used so far for such a detailed fragment of the Łódź Plateau. The aim of this paper was to show the possibility of detailing topographic and geomorphological analysis and re-imagining the features of the Łódź Plateau relief on the example of a case study of the Mroga and Mrożyca interfluvial area. In this case, the use of GIS modelling confirmed the main features of the strongly transformed relief of the Mroga and Mrożyca interfluvial area, which is a result of overlapping elements of relief formed during the Warta stadial of the Odra Glaciation and further, during periods of the Vistulian and Holocene morphogenesis.

Objectives: The present study aimed to assess the risk of cancer due to benzene in the ambient air of gas stations and traffic zones in the north of Tehran. The cancer risk was estimated using the population distribution data for benzene levels and the unit risk for benzene proposed by the United States Environmental Protection Agency (US EPA). Material and Methods: Sixteen sampling locations were monitored, once every week, during 5 April 2010 to 25 March 2011. Results: The results showed that the mean annual benzene concentration was 14.51±3.17 parts per billion (ppb) for traffic zones and 29.01±1.32 ppb for outside gas stations. The risk calculated was 1026×10⁻⁶ for gas station 27 and 955×10⁻⁶ for gas station 139. Conclusions: According to our results, the annual benzene level in Tehran ambient air is 2 to 20 times higher than the respective value specified in International Standard (1.56 ppb). Moreover, the results showed a notable increase of cancer risks, ranging from 10% to 56%, for the vicinity population close to the gas stations in comparison to the vicinity population in the traffic zones.
