Title: INFLUENCE OF TIME OF CONCENTRATION ON VARIATION
         OF RUNOFF FROM A SMALL URBANIZED WATERSHED
DOI: 10.15576/GLL/2015.2.7

Published: 24 September 2015PDF[download]
The main objective of the paper is to estimate the influence of time of concentration (TC) on maximum flow in an urbanized watershed. The calculations of maximum flow have been carried out using the Rational method, Technical Release 55 (TR55) procedure based on NRCS (National Resources Conservation Services) guidelines, and NRCS-UH rainfall-runoff model. Similarly, three methods were used to calculate the overland flow component of the TC: the Kerby method, the Morgali and Linsley method and the NRCS travel time method.
The TC was calculated in a watershed located in Krakow city in Poland, małopolskie voivodeship. Total area of the watershed has about 180 ha. It's a highly urbanized watershed with a significant land cover (29.6% of total area) influencing the runoff, in the form of an impervious industrial area.
The highest value of time of concentration was achieved for Morgali and Lindley method in case of the subwatershed with dominant pervious areas, as opposed to the NRCS method for the subwatershed with dominant impervious areas. The highest value of TC was obtained for NRCS method. With reference to the whole watershed, the highest values of the time of concentration were obtained for the MorgaliandLindley method and the lowest for the Kerby formula. Based on this study, authors recomended the Kerby method for estimating TC for overland surface dominated areas because this method requires only a small number of input parameters, that are straightforward to estimate.

Title: THE PROPOSITION OF A NEW DAMPING FUNCTION FOR OUTLIERS IN THE ADJUSTMENT PROCESS
DOI: 10.15576/GLL/2015.2.21

Published: 24 September 2015PDF[download]
This study proposes of new damping function in the robust estimation process. The formulae for a behaviour of the damping function were provided and a diagram of adjustment process was presented. The numerical examples are given in order to assess the efficiency of the proposed computational algorithm in accomplishing a typical geodetic task with outliers or gross errors.

Title: CORRECTIONS TO SEA LEVEL ANOMALIES DATA DUE TO GEOCENTER MOTION
DOI: 10.15576/gll/2015.2.33

Published: 24 September 2015PDF[download]
The objective of this paper is computation of the corrections to sea level anomaly data due to center of Earth mass variations. The geocenter motion model was computed from the center of mass coordinates data determined from observations of space geodetic techniques such as Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS) and Doppler Orbitography and Radiopositionig Integrated on Satellite (DORIS). In order to compute the geocenter motion model the center of mass coordinates data were filtered using wavelet based semblance filtering which allows computing a common signal in two time series. Based on determined geocenter motion model a correction to sea level anomalies (SLA) data due to geocenter motion was determined. This kind of correction to sea level anomaly data is of the order of few millimetres and should be applied to altimetric measurements to refer them to the International Terrestrial Reference Frame (ITRF) Origin considered as the center of figure.

Title: THE POSSIBILITIES OF USING CHOSEN JQUERY JAVASCRIPT COMPONENTS
         IN CREATING INTERACTIVE MAPS
DOI: 10.15576/gll/2015.2.45

Published: 24 September 2015PDF[download]
The availability, functionality and usability of interactive maps and digital representations of environment in Internet are on the rise. Their popularity results mainly form the technological progress and development of programming tools available as open source, and from the growing demands of users who are looking for specialist geoinformation services in Internet. The goal of this study is to analyse the possibilities of using chosen programming techniques and tools such as jQuery JavaScript components to creating interactive maps. JQuery was chosen because it is one of the most popular technology of making web applications.
The analysis was possible thanks to tests of three web applications created on the basis of chosen scripts, available under open source licence. The research showed that jQuery library can be used to creating web map applications but in a limited scope.

Title: DIGITAL TERRAIN MODEL AS A BASIS FOR DETERMINING THE FLOODLAND OF THE PRĄDNIK RIVER
DOI: 10.15576/gll/2015.2.55

Published: 24 September 2015PDF[download]
The modern technology gives us the possibility to make a Digital Terrain Model, which is more and more frequently used in various scientific fields. Localizing the floodland on the basis of Digital Terrain Model provides an insight into the reality and is relatively quick.
On the basis of the materials from photogrammetric flight the Digital Terrain Model was prepared, which was measured at the digital station "Delta". The model has been supplemented by elements of land cover, that is meadows and pastures, built-up areas, roads, escarpments, forests and waters. By using the software Surfer a spatial (3-D) model of a studied area has been created. The floodland of the Prądnik river, when the water level is higher by 2 and 5 meters, have also been visualised.

Title: THE ASSESSMENT OF AGRICULTURAL USE OF MOUNTAIN VILLAGE GRASSLANDS
         — ON THE EXAMPLE OF THEIR SPATIAL ARRANGEMENT
DOI: 10.15576/GLL/2015.2.63

Published: 24 September 2015PDF[download]
The agriculture in mountain areas is still one of the main sources of income for their inhabitants. The faulty land layout of highly fragmented farms and dispersion of lands have no positive impact on their agricultural use. However, abandoning agricultural production due to the functions it fulfils in these areas for the cultural landscape, natural biodiversity, is neither imaginable nor even possible. Clean natural environment, friendly to organic farming and favourable conditions to livestock and pasture farming still make the agriculture an important economic activity in these regions. The economic significance of agriculture in mountain and sub-mountain regions has been decreasing, because tillage of these lands requires more effort and its productions costs are higher. That is why the financial support for these regions is necessary. The study attempts to prove the following: because the agriculture in these regions is based on traditional livestock and pasture farming, these lands are agriculturally useful, especially when they are used as grasslands. The study was carried out in a mountain village Polski Spisz (near Nowy Targ) that has one of the highest land fragmentation index, where the average 5 ha farm consists of 45 land plots (parcels), and the mean size of a land plot designed for grassland is only 0.1 ha. In the whole village there are almost no parcels larger than 1 ha that would be appropriate for tractor tillage. It is necessary to carry out rural management works and to transform agricultural lands, change the current structure of land use by significant reduction of arable lands in favour of grasslands.

Title: REVITALIZATION — DEFINITION, GENESIS, EXAMPLES
DOI: 10.15576/gll/2015.2.71

Published: 24 September 2015PDF[download]
In the paper a definition of revitalization and the term’ origins in practical use are presented. The examples of cities, districts, post-industrial areas are given, which, thanks to revitalization processes, have been changed from vacant places and wastelands into objects with new, attractive functions. Among the objects described in the article are: Berlin’s districts Kreuzberg, Nature Park Schöneberg Südgelände, Promenade plantée of Paris and American: High Line Park, Brooklyn Bridge Park and Freshkills Park. Moreover the paper addresses the issue of Detroit, the city which is being subjected to comprehensive revitalization. The presented examples have confirmed that urban centres are degraded by manifold factors, mainly social and economic, and that their revitalization requires the use of specific, individualized solutions compatible with the need of a given object.
