Empirical models are models based on inductive logic, and generally are applicable only to those conditions for which the parameters have been calibrated or used for identifying the sources of sediments since they are developed from the experimental measurement or field measurement (Merritt et al. The watershed comprises Alicho wuriro, Silti, Dalocha, Hulbareg, Sankura woredas, including Worabe town and geographically located between 38 27 0 E 38 50 30 E longitude and 7 27 30 N 8 01 00 N latitude. Habitats however have been degraded, mainly by grazing of livestock as well as cutting of trees for firewood and clearing of land for planting. Protected areas include Yangudi Rassa National Park and Mille-Serdo Wildlife Reserve in Ethiopia, Nakfa Wildlife Reserve in Eritrea, and the Djallo and Assamo terrestrial protected areas in Djibouti. However, the wetter margins are excellent for livestock, and even the drier margins respond well to irrigation. Omissions? Simien Mountains National Park, home to several endangered species, was designated a UNESCO World Heritage site in 1978. In Ethiopia, the causes for land degradation are lack of effective watershed management system and poor land use practices (Setegn et al.

Eight factors/parameters such as soil type, soil depth, soil texture, soil drainage, slope, distance from a water supply, and land cover were used to evaluate the suitability of the area for surface irrigation. 1997).

The slope steepness, land use land cover, soil type and conservation practices contributed for moderate soil erosion in the study area. Geomorphological Landscapes of Ethiopia. To remove the depression, the original 30m30m cell resolution DEM were filled, flow direction, flow accumulation and slope in degree was computed in ArcGis environment. This introductory chapter reports about the main geographic and geomorphologic features of Ethiopia. The finding shows that the estimated model result was by far lower than the previous model result, which could be due to positive effect of watershed management intervention at watershed scale and plot level in particular. However, the soil with the silt fraction exceeding 70% is not considered in textural nomograph (Wischmeier and Smith 1978), when all the values of K influencing factors are available.

This could be attributed to mixed plantation of acacia species, Eucalyptus globulus, and cupperesus lustanica. Therefore, the soil erosion could be reduced if the current land use land cover scenario is considered. These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. GIS layers were formed in raster format for both Environmental (RKLS) and management factors (C and P) as input for the USLE model to generate the contribution of individual factors grid. Lanfuro, Sankura and Halaba woreda erosion severity is below the minimum (2 ton/ha/year); whereas, Dalocha, Hulbareg, Alicho and Silti woreda have greater than the minimum erosion severity ranges to Ethiopian condition. The major soil types of Dijo watershed were Molic Andosols, Pellic vertisols, chromic luvisols, Haplic Phaeozems, Eutric Cambisols and Lithosols. The characteristics of soil, watershed topography (gently sloping and sloping), lack of vegetation cover, cultivation of steep slope without engineering measures, free grazing and sand extraction contributed for moderate soil erosion. 15).

Based on the classification, two sub watersheds fell under very low erosion severity classes (01 ton/ha/yr), 22 sub-watersheds fell under low erosion severity classes (15 ton/ha/yr). Because Ethiopia is located in the tropical latitudes, its areas of lower elevation experience climatic conditions typical of tropical savanna or desert. 8), which is within the ranges of Bekele et al. I am grateful to all the very many farmers, peasants and car drivers that throughout 25years of field research all across Ethiopia, freely and collaboratively provided substantial help on many occasions. Even on the cool plateaus, where good volcanic soils are found in abundance, crude means of cultivation have exposed the soils to heavy seasonal rain, causing extensive gully and sheet erosion. Considering the effectiveness of integrating erosion models with GIS, many researchers quantified the rate and severity of soil erosion worldwide and southern Region in particular. The conservation status of this ecoregion is not good, with few protected areas and lack of enforcement in existing ones.

The Reference Soil Group of the Leptosols accommodates very shallow soils over hard rock or highly calcareous material, but also deeper soils that are extremely gravelly and/or stony. Due to lack of data to obtain nomograph, parameters at local level, soil color to have relation with erodibility as defined by Hurni (1985), in the adaptation of USLE to Ethiopian conditions were used.
