    Opis:
    The paper presents the ecological effects of land consolidation carried out in upland loess areas. The design of a large plot of land on a slope with a gradient of up to 18% and its impact on the intensity of water erosion were investigated. The analyzed plot was created by consolidation 12 smaller plots. Before the consolidation, all plots had a cross-slope layout and direction of agrotechnical operations. Exactly the same arrangement remained after the consolidation. The WEPP simulation model was used for the comparison of the pre-consolidation and postconsolidation state. The amount of soil loss and sediment yield was estimated under different scenarios of slope management. It was found that after consolidation (creation of a plot with the width of more than 130 m), as a result of removing of terraces and sodded cross-slope scarps, the intensity of erosion increased many times. In order to restore the anti-erosion effect of cross-slope cultivation on such a slope without increasing the difficulties of agrotechnics, it is necessary to restore the sodded scarps that existed before consolidation. The simulation results show that the scarps should be located transversely to the slope (along the plot) in the middle and lower parts of the slope, in the place of the highest inclination. As advantage of the consolidation project was considered the elimination of longitudinal balks which were focuses of linear erosion on the slope.

    Opis:
    The knowledge on the spatial variability and hydrological behaviour of contributing areas to specific outlet is a fundamental input for developing appropriate water resource planning and management actions that take part in various areas of human activities. The aim of this contribution is to present the possibilities to assess the precipitation-runoff process and soil erosion risk in a specific area using the theoretical approaches with the simplest requirements for meteorological and surface runoff data. Considering the connectivity and behaviour of natural processes, the analysis of precipitation-runoff process and soil erosion risk is crucial prior to the design of technical water management practices and technical erosion control measures in the landscape. The characteristics of design rain, e.g. the intensity, annual frequency and duration can be determined using practical tools or according to the analysis of the cost and damages related to specific technical measure. The intensity of design rain can be estimated according to the long-term meteorological observations and intensity-duration-frequency curves developed using region specific equations (Dub’s formula, Urcikan’s formula). For the design of water management, conservation (especially erosion) or other measures for ecological stabilization and protection of the area, it is important in particular to determine the following characteristics of surface runoff: beginning of surface runoff, design discharge from the contributing area, the depth of the surface runoff, and the volume of surface runoff. Estimating the soil erosion risk by water erosion can be done according to the slope gradient or USLE calculation and subsequent comparison of estimated value with tolerable soil loss. Regardless of the location of specific areas, we have found that the design parameters of water management and technical erosion control practices, facilities and measures, including their localization can be determined by applying and modifying the existing theoretical and practical hydrological knowledge. We also found that this design cannot be executed without an analysis of the precipitation-runoff process and the erosion risk of this territory. In relation to the climate change and changing rainfall patterns in all regions worldwide, further studies should be conducted to specify the regional characteristics of precipitation, soil and its usage.

    Opis:
    The vulnerability of soil by wind erosion using the wind erosion equation (WEQ) in geographic information systems (GIS) was demonstrated on the cadastral area of Přísnotice, southeast of the Czech Republic. Raster layers were created for input factors of WEQ and potential soil loss by wind was calculated using the Raster Calculator. Subsequently, map outputs showing the potential vulnerability of soil to wind erosion were made. In the first variant, where the protective effect of the barriers was not taken into account, the wind erosion intensity reached 47.6 t.ha-1.year-1. In the second variant, where the protective effect of the barrier was assumed, the loss of soil was lower, the maximum value was 4.7 t.ha-1.year-1. The soil loss limit was exceeded, even in a situation where a relatively high protective barrier effect has been proposed. The advantage of determining of wind erosion vulnerability using ArcGIS is that it is possible to identify particular parts of soil blocks from the map outputs, which are the most vulnerable. Similarly, it is possible to design a windbreak network and simulate its protective effect using ArcGIS.

    Opis:
    Soil erosion by water is an important economical issue strongly deteriorating environment and requiring remedial actions. The study was designed to evaluate antierosion effect of changes in the layout of plots from along to across slope as an effect of land consolidation. Moreover, rightness of leaving newly set out boundaries of plots without any protection (i.e. sodding) was evaluated. For this purpose simulations of use of additional anti-erosive measures were done. The Water Erosion Prediction Project (WEPP) model was used. Studies have shown that in addition to the design of transverse layout of parcels during consolidation, further antierosion measures may be necessary to reduce soil loss and sediment yield. In order to minimize soil losses outside the slope, boundaries between the newly designed fields should be sodded already in the post consolidation management. Limitation the amount of erosion over the entire slope requires use of additional protection measures in the upper part of slopes e.g. shelterbelts and antierosion crop rotations. WEPP model can be recommended for Provincial Bureaus of Surveying as a tool to support the development of assumptions for consolidation projects of lands threatened by erosion.
    Erozja wodna gleb jest ważnym zagadnieniem gospodarczym, silnie pogarszającym stan środowiska, wymagającym działań zaradczych. Badania miały na celu ocenę przeciwerozyjnych efektów zmiany układu działek z wzdłużstokowego na poprzecznostokowy w wyniku scalenia gruntów. Oceniono też słuszność pozostawienia nowo wytyczonych granic działek bez zastosowania żadnych środków przeciwerozyjnych (np. zadarnień). W tym celu dokonano dodatkowej symulacji zastosowania różnych środków przeciwerozyjnych z wykorzystaniem modelu WEPP (ang. Water Erosion Prediction Project). Badania wykazały, że poza zaprojektowaniem w trakcie scalenia układu poprzecznostokowego niezbędne mogą być dalsze środki przeciwerozyjne, aby ograniczyć erozję gleby i jej wynoszenie poza obszar stoku. Aby zminimalizować straty gleby poza stok, należałoby już w trakcie zagospodarowania poscaleniowego zadarniać granice między nowo zaprojektowanymi polami. Ograniczenie rozmiarów erozji na całym stoku wymaga stosowania dodatkowych umocnień w górnych partiach zbocza, np. zadrzewień śródpolnych oraz płodozmianów przeciwerozyjnych. Model WEPP może być rekomendowany Wojewódzkim Biurom Geodezji jako narzędzie wspomagające opracowanie projektów scalania gruntów na terenach zagrożonych erozją.
