“…Contrastándose con los resultados reportados por Latocha et al (2016) los materiales cartográficos permitieron la distribución espacial de los cambios de uso de la tierra y cobertura vegetal. El generalizado deterioro de las tierras cultivables es el factor más importante de la erosión del suelo, como motivo de arado son por lo general las fuentes más eficaces para el transporte de material de las pistas.…”

ResumenSe realizó la evaluación de la erosión física y química del suelo en la zona nor -occidental de la provincia Bolívar-Ecuador, en las comunidades El Carbón, Culebrillas y Los Casaiches. Por su topografía se dividió cada localidad, en parte superior, media e inferior; para el análisis descriptivo-comparativo y dinámica de erosión en los perfiles A, B y C. Las variables físicas evaluadas fueron: procesos erosivos gravitacionales y denudativa, la morfogenética y textura del suelo; y las químicas pH y materia orgánica. El análisis de textura mostró heterogeneidad a distintas profundidades por comunidad: los Casaiches (15,66 %) suelo arenoso a profundidades de (0 -10 cm), con crecimiento hasta profundidades de 30 cm (19,91 %) y decreciendo hasta los 50 cm (15,18%); la textura arenosa en El carbón y Culebrillas desciende a profundidad de 50 cm. Culebrillas presentó en todos los niveles contenidos de limo (14,14 % a 18,15%) superiores a las del Carbón y los Casaiches. El contenido de arcilla presentó similitudes a profundidad de 0-10 cm (37,12 %), creciendo a medida que se incrementó la profundidad; El Carbón mostro el mayor contenido de arcilla con 52,27%. Los parámetros químicos indicaron suelos ligeramente ácidos, pH entre 5,60 y 6,45 e incrementos de materia orgánica en los horizontes eluviales. Los resultados reportaron que la erosión antrópica es el principal factor de degradación de los suelos (a profundidades de 0 -30 cm) en la zona, generando cambios profundos en la topografía, biota y sobre las propiedades físicas y químicas del suelo. Palabras claves: Proceso erosivo gravitacional, Textura del suelo, Evaluación fisicoquímica, Topografía AbstractEvaluation of physical and chemical soil erosion took place in the north-western zone of the province of bolivarEcuador, communities Coal, Culebrillas and Los Casaiches. By its topography each locality was divided into upper, middle and bottom; for descriptive-comparative and dynamic erosion profiles A, B and C. The physical variables were evaluated analysis: Gravitational and denudativa erosional processes, morphogenetic and soil texture; and chemical pH and organic matter. Texture analysis showed heterogeneity by various depths community: Casaiches (15.66%) sandy soil depths (0-10 cm), with growth to depths of 30 cm (19.91%) and decreasing to 50 cm (15.18%); sandy texture Coal and Culebrillas down to depth of 50 cm. Culebrillas provided at all levels of silt content (14.14% to 18.15%) higher than Coal and Casaiches. Clay content presented similarities 0-depth of 10 cm (37.12%), growing as the depth increased; Coal showed the higher clay content with 52.27%. The chemical parameters indicated slightly acidic soil pH between 5.60 and 6.45 and increases organic matter in the eluvial horizons. The results reported anthropic erosion is the main factor of degradation (to depths of 0-30 cm) in the area, generating profound changes in topography, biota and the physical and chemical properties of soil.

“…The R factor reflects the potential erosivity associated with the rain for soil erosion, and it is determined by the volume, intensity and duration of rainfall [43]. The R factor is traditionally obtained based on the EI 30 index and its corresponding individual rainfall datasets, and the EI 30 index refers to the product of rain kinetic energy (E) times the biggest rain density in 30 min (I 30 ).…”

“…The R factor is traditionally obtained based on the EI 30 index and its corresponding individual rainfall datasets, and the EI 30 index refers to the product of rain kinetic energy (E) times the biggest rain density in 30 min (I 30 ). In order to overcome the data limitations, simpler methods based on the monthly or annual precipitation data have been proposed to estimate the rainfall erosivity [43,44]. In our study, the annual R was calculated as Equations (2) and (3) based on the monthly precipitation data [45].…”

The adjacent agricultural watershed is a vital component of the Three Gorges Reservoir Region (TGRR); however, it is affected by serious soil erosion. Assessing soil erosion dynamics in such watersheds is useful for identifying its causes and tendencies to develop, in turn providing scientific information for soil and water conservation at the regional scale. In the present study, the spatial and temporal patterns of soil erosion of a small agricultural watershed in central TGRR were investigated from 2002 to 2014 using the Revised Universal Soil Loss Equation (RUSLE) model, combined with Geographic Information Systems (GIS). The trends and processes of the overall soil erosion intensity were analyzed using spatial overlay analysis and the Markov transition matrix model, respectively. The spatial distribution of soil erosion rates within this watershed was relatively consistent during the study period. Erosion intensity was moderate, with a mean soil loss of 35.1 t·ha −1 ·year −1 . Precipitation was a dominant factor influencing the intensity of soil erosion. Moreover, most erosion intensities shifted closely to middle grades from 2002 to 2008, and declined from 2008 to 2014, indicating that soil erosion in the Wangjiagou watershed has recently decreased. These results suggest that recently implemented integrated soil management practices were responsible for the recently observed erosion patterns.

“…The monthly mean precipitation totals for HP were compiled by the German Reichsamt für Wetterdienst, and published in Klimakunde des Deutschen Reiches (1939). Data for HP were prepared as geodatabase (Latocha et al 2016) and consists of 368 stations. The CP geodatabase includes measurements provided by the Institute of Meteorology and Water Management in Poland and consists of 245 stations (Fig.…”

In this paper, we quantify the changes in precipitation distribution in south-western Poland between the periods 1891-1930 and 1981-2010. The average monthly precipitation totals available for 368 and 245 stations, respectively, are spatially interpolated and processed to calculate maps of differences and pluvial continentality indices for both periods. The maps are analysed against changes in atmospheric circulation and take into account the potential role of the mountain barrier of the Sudetes. The main findings are (1) winter totals generally increased in conjunction with a higher frequency of zonal circulation; it is more pronounced in the upper parts of the Sudetes due to orographic effects; (2) a decreased frequency of zonal circulation together with an increased frequency of southern flows has likely led to the reduction of precipitation in spring and autumn. These changes have led to a significant modification of the region's pluvial regime, mostly by decreasing continentality features (especially in the Sudetes and the western lowlands). In addition, the strong sheltering influence of the mountain barrier is observed, driving the preservation or even the enhancement of the continental pluvial characteristics in the north-eastern to eastern foregrounds of the Sudetes. This leads to the conclusion that in areas where long-term observed trends or future projections of precipitation are ambiguous, there may occur significant modifications in regional characteristics, especially as a result of changes in atmospheric circulation modified by local orography.
