Opis:: The construction of the Keuliling Reservoir aims to accommodate and utilise water for agricultural purposes. In this research, soil erosion modelling using the USLE method showed that the level of erosion hazard for each Keuliling Reservoir sub-watershed was classified into low-moderate. Land erosion occurred in the area around the reservoir inundation is the most significant contribution to the magnitude of erosion (38.62Mg∙ha-1y-1. Based on the point of sediment sampling in the Keuliling reservoir, the sediment volume was 1.43 Mg∙m-3. So, the volumetric sediment input from the Keuliling reservoir watershed is 20.918,32 m3∙y-1. The degradation of reservoir function due to sedimentation can affect reservoir services. The ability to estimate the rate of watershed surface erosion and sediment deposition in the reservoir is vital for reservoir sustainability. Besides the land erosion in the Keuliling Reservoir, there are also other potential sources of erosion that can reduce the capacity of the reservoir, i.e. the rate of sedimentation from a reservoir cliff landslide. The USLE estimation results show that the soil erosion analysis provides important and systematic information about nature, intensity and spatial distribution in the watershed and sediment volume in the Keuliling Reservoir. This finding allows the identification of the most vulnerable areas and the type of erosion dominant for long-term land management.

Opis:: Soil loss assessment in watersheds is useful in developing plans for the protection and conservation of soil and water in a sustainable manner. This study aimed to determine erosion hazard classification and erosion hazard map using Revised Universal Soil Loss Equation (RUSLE) as the basis of a soil and water conservation planning program. The RUSLE model was used to assess soil loss and guide the soil conservation efforts. Annual rainfall data, digital elevation model (DEM), land use map were used to generate the RUSLE parameters, namely rainfall-runoff erosivity factor (R), soil erodibility factor (K), slope length and steepness factor (LS), cover-management factor (C), and support practices factor (P). Erosion hazard is classified into five classes, namely very low, low, medium, high, and very high. On the basis of the results, at the Dolago watershed, very high erosion hazard was found in dryland of 577.95 t/ha/yr. Meanwhile, very low erosion hazard was found in the rice field of 2.22 t/ha/yr. The results help in planning and implementing soil and water conservation, both vegetatively and mechanically, to minimize the damage to watershed ecosystems. Validation and testing of the RUSLE model should be carried out in future studies because this is a strategic step to develop modeling of sediment yields effectively in an effort to mitigate major land damage in watersheds.

Opis:: Soil erosion in the Nangka watershed has always been a matter of concern. Over the last decade, soil erosion has led to continuous environmental problems. A thorough examination of the extent of the problem was required to identify an appropriate soil conservation strategy within the watershed. This study was conducted to observe erosion rates and map out the erosion hazard level. Erosion predictions were analysed by using the Revised Universal Soil Loss Equation (RUSLE) model with the help of ArcGIS software. RUSLE was selected because of its quantitative ability to estimate average annual soil erosion and its compatibility with the GIS interface. The potential hazard of soil erosion was classified and ranked into five class categories as set by the national authority. The results reveal that the Nangka watershed is prone to soil erosion with the annual average values ranging from 1.33 Mg·ha-1·y-1 to 2472.29 Mg·ha-1·y-1. High soil erosion rates of 9.8% are in severe (class IV) and very severe (class V) conditions, primarily in the upper course of the watershed. The low annual average of soil erosion (class I and class II), which accounted for 75.95% of the total erosion, mostly took place in the steepness below 35%. The remaining area of 14.25% within the watershed is in moderate condition (class III). It is expected that the results of this study will help the authority in the implementation of soil conservation measures.

Opis:: W pracy przedstawiono wyniki pomiarów rozbryzgu i zmywu gleby oraz spływu powierzchniowego na poletkach z burakami cukrowymi oraz utrzymywanymi w ugorze. Na poletkach z burakami prowadzono pomiary wskaźnika ulistnienia oraz wysokości roślin. Stwierdzono, że efektywność okrywy roślinnej w ograniczaniu zmywu gleby można ze zbliżoną dokładnością ocenić za pomocą obu parametrów roślinnych. Opracowano model do prognozowania zmywu gleby dla uprawy buraków cukrowych w oparciu o energię kinetyczną opadu i wskaźnik ulistnienia.
Results of field experiments conducted according to the USLE method are presented. Together with measurements of splash,soil loss, and runoff leaf area indexand plant height were eveluated. Effectiveness of crop cover in limiting of erosion was correlated with both plant parameters at similar level.A regression model to predict soil loss on the basis of kinetic energy and leaf area index was proposed.

Opis:: W pracy przeanalizowano zmiany składu granulometrycznego i zawartość materii organicznej w glebie, która uległa zmyciu z kolein w czasie 30 minutowego deszczowania. Erozję wodną gleby badano w koleinach utworzonych ciągnikiem oraz w koleinach pozostawionych przez ciągnik z przyczepą. Pomiary wykonano na glebie lekkiej w warunkach kontrolowanych przy użyciu symulowanego deszczu.
The study examines changes in texture composition and organic matter content in the soil which was washed away from ruts in the course of a 30 minute sprinkling. Water erosion was examined in ruts made by a tractor and in ruts made by a tractor pulling a trailer. Measurements were taken on a light soil in controlled conditions using sprinkling.

Opis:: Comparison of commonly acting gullying and muddy floods at present (in the post-collectivization period) and in the past (mostly in the period of the 16th to 19th centuries) has showed considerable disparities; they are conditioned by the character of land use and climate changes, mostly in the case of their synchronous occurrence what has profoundly multiplied their geomorphic response.In the case when extreme events occur in the area with permanent, historical gullies, the current common operation of gully erosion and muddy floods can show similar features with their acting in the past.In such cases the material of muddy floods is coming not only from fresh ephemeral gullies but also from old permanent gullies that were deepened during these events.It was confirmed during extreme events that happened in cadastral areas of two villages in western Slovakia in 2009 that were not comparable with geomorphic effects of other events within the last period.
