This study presents the results of tests conducted in 2009 and 2010 on experimental sites installed on the roof of the Science and Education Building of the Wroclaw University of Environmental and Life Sciences. The aim of the analysis was to determine the retention capacity of green roofs and the runoff delays and peak runoff reduction during rainfall recorded in Wroclaw conditions.
The research shows that green roofs allow to reduce the volume of runoff stormwater in comparison to conventional roofs, that they delay the runoff in time and influence the reduction of the maximum runoff intensity, and thus may limit the impact of stormwater on the stormwater drainage and combined sewage systems.
The aim of the article was to determine the course of changes the urban space under the influence of tourism, on the example of selected areas in Cracow. A literature study, statistical data and field studies were used to explain the relationship between the growth of tourist movement and the development of the tourist space of this city. The impact of tourism on changes in public and private space use within Matejki Square and Pawia Street, in the neighbourhood of the historical zone (Old Town) and in the New Square at Kazimierz, was analysed. The conducted analysis showed three functional changes of the studied areas under the influence of the rapid tourist movement. They were transformed from residential-service to service-residential related to service of tourists (hotels, gastronomy, trade, entertainment). The urban space has been enriched with elements that increasing the tourist attractiveness of Cracow compared with other cities, for example, concerning spending free time (pubs, cafés, restaurants), and the new accommodation base near the city-centre. A lack of a zoning plan and development vision causes the helplessness of the local authorities in managing the tourist infrastructure development, which is reflected at the Kazimierz New Square.
The aim of the presented work is to prove that construction of large sports facilities in the urban space, can generate positive changes and revitalization of degraded areas. On the basis of comparative analysis of cases in which such activities took place, it can be concluded that locating these facilities in heavily degraded urban areas is one of the most eff ective methods of large-scale revitalization. This is mainly visible in post-industrial areas, which are usually well linked to canals, rivers and other waterways or reservoirs. The vast spaces around sports facilities create favorable conditions for additional recreational functions, such as parks and green areas, which in connection with water become a very attractive place for the residents of the city. Increasing interest in the area leads to new investments such as housing estates and gradual development of a multi-functional urban structure. One of the most important factors leading to this type of transformation is the modernization of the communication infrastructure which enables connection between revitalized areas and the rest of the city. A well-planned program of newly emerging sports facilities is also an extremely important factor. As research shows, large multifunctional sports and entertainment facilities, can function as a new kind of public space in the city. This leads not only to the establishment of completely new social relations, but also to the creation of jobs and the general improvement of the broadly understood image of the district.
Flood inundation processes in urban areas are primarily affected by artificial factors such as drainage facilities, local al-terations of topography and land uses. The objective of this study is to examine the capability of hydrological model SI-MODAS to estimate runoff and investigating the utilization of storage well in controlling runoff in a residential area. The result of the estimated runoff from the hydrological model was compared with the existing capacity of the drainage channel to identify which channel experienced the problem of inundation. The location of inundation was used to determine the location and number of storage well. The results showed that SIMODAS model could be applied in runoff analyses with 8.09% of relative error compared with runoff depth from field measurement. The existing capacity of the channel could not accommodate runoff Q10yr where the inundation discharge was approximately 0.24 m3·s–1 (at outlet point 1) and 0.12 m3·s–1 (at outlet point 2). The inundation problem was overcome by using a combination system between channel normalization (reduce 35% of total inundation discharge) and storage well system (reduce 65% of total inundation discharge). The storage well was designed at 20 locations (at outlet point 1) and 16 locations (at outlet point 2) which each well had a discharge of 0.0058 m3·s–1. The storage well combined with channel normalization could be used as an alternative way to solve inunda-tion problems in a residential area considering the constraint of land space limitation in the urban area.
This article addresses the issue of the role of regions, big cities and urban areas in the socio-economic and spatial development trends in the EU as well Poland shaped through – and in connection with the process of globalization and functioning of the Common Market. The analysis of the situation and trends is prepared on the basis of the recent reports and data presented by the EC and OECD and – in case of Poland – Ministry of Investment and Economic Development as well Main Statistical Offi ce. Against this background with the reference to other research work published recently and his own experience the Author formulates a number of proposals for modification of territorially sensitive socio-economic policy in Poland (at national, regional as well urban level).
The article discusses selected issues concerning both the activities and the contents of Strategy Cracow 2030 – An Ambitious Plan of the City Where Life Can Be Enjoyed. The author analyses how selected concepts well known in the local and regional development policy literature and practice such as territorial capital, second-tier city, integrated territorial planning and metropolisation are refl ected in the key development planning document of the second-largest Polish city. The strategy was adopted by the City Council in February 2018. The article focuses in particular on the applied work method, based on an advanced partnership and cooperation of key stakeholders, assumptions adopted in the strategy and axiology, identified challenges and development resources, and metropolitan city aspirations. The author also discusses selected issues regarding implementation system of the strategy.
In recent years, the rate of urban growth has increased rapidly especially in Egypt, due to the increase in population growth. The Egyptian government has set up new cities and established large factories, roads and bridges in new places to solve this trouble. This paper investigates the change monitoring of land surface temperature, urban and agricultural area in Egypt especially Kafr EL-Sheikh city as case study using high resolution satellite images. Nowadays, satellite images are playing an important role in detecting the change of urban growth. In this paper, cadastral map for Kafr El-Sheikh city with scale 1:5000, images from Landsat 7 with accuracy 30 meters; images from Google Earth with accuracy 0.5 meter; and images from SAS Planet with accuracy 0.5 m are used where all images are available during the study period (for year’s 2003, 2006, 2009, 2012, 2015 and 2017). The analysis has been performed in a platform of Geographical Information System (GIS) configured with Remote Sensing system using ArcGIS 10.3 and ERDAS Imagine image processing software. From the processing and analysis of the specified images during the studied time period, it is found that the building area was increased by 28.8% from year 2003 up to 2017 from Google Earth images and increased by percentage 34.4% from year 2003 up to year 2017 from supervised Landsat 7 images but for unsupervised Landsat 7 images, the building area was increased by percentage 35.9%. In this study, land surface temperature (LST) was measured also from satellite images for different years through 2003 until 2017. It is deduced that the increase in the building area (urban growth) in the specified city led to increase the land surface temperature (LST) which will affect some agricultural crops. Depending on the results of images analysis, Forecasting models using different algorithms for the urban and agricultural area was built. Finally, it is deduced that integration of spacebased remote sensing technology with GIS tools provide better platform to perform such activities.
The article aims to present the scope of influence of Integrated Territorial Investments (ITI) on the sustainable development of urban functional areas (FUAs) in Poland. Against the background of the general principles of the implementation of the both instruments, practical aspects of the implementation of ITI in FUAs have been presented. Detailed analyses in the financial and spatial aspect were carried out using the Sustainable Development Indicators (SDI). These provided the basis for presenting the practical aspect of supporting the sustainable development of urban functional areas in the EU Cohesion Policy 2014–2020.
