A common phenomenon occurring in small river basins is an increase of spatial development in the period of last 20 years. This development is an effect of economic changes in our country, resulting in growing land cover by all sorts of infrastructure as well as in changes in method of development. It may be observed both giving up the intensive agricultural use in large parts of arable areas and even greater intensification of agricultural use in some selected favorable situated locations. Those processes are of increasing character and lead to substantial changes in hydrological conditions of runoff, which imposes the necessity of verification of the functionality of the existing water regulation structures. The authors have presented issues connected with changing basin storage and determined the influence of spatial development on basin surface sealing and rainwater storage. Concepts of land use changes were presented; calculations of water storage reservoir capacity were made, as well as the influence of storage deficit and changes in forest cover magnitude on bedload transport conditions. Critical parameters of bedload movement were calculated. ...
The paper presents effectiveness of LUCAS research method on the exam-ple of nine districts Małopolskie voivodeship. The study was conducted from march to july 2006. There were 520 research points located in the following districts: krakowski, Kraków, wielicki, limanowski, wadowicki, myślenicki, suski, nowatorski, tatrzański. Research points were specified by Eurostat randomly. The analysis reveal numerical distribution in land cover categories and land use cate-gories. The survey results allowed to define the use of land (land development) on the studied area. The link between land cover and land use allowed to evaluate percentage of points assigned to land use and land cover categories. The final re-sults are presented on the land use and land cover maps. ...
Airborne laser scanning is is rapidly developing a fast method for obtaining spatial information. Data obtained from the aeroplane or helicopter, besides the three coordinates (X, Y, Z) are often enriched also recorded the amount of energy that is reflected from the different surfaces. In this way, besides the geometric representation of reality we get the image of diversity surfaces, which in different ways reflect the laser beam.
