Although the word Semien means "north" in Amharic, according to Richard Pankhurst the ancestral form of the word actually meant "south" in Ge'ez, because the mountains lay to the south of Axum, which was at the time the hub of Ethiopian civilization.

Lithosols are shallow soils consisting of imperfectly weathered rock fragments having sandy clay soil texture classes. Amsalu, T. and Mengaw, A. 2001).

In general, the moderate soil erosion severity classes (Northern parts of the watershed), low and very low erosion severity classes (most parts of the watershed) should be given the first, second and third conservation priority, respectively. 2). The moderate soil erosion at Alicho and Silti site is due to free grazing after crop harvest, the steeper topographic nature of the watershed, lack of integrated physical and biological soil and water conservation measures in many steeper and very steeper topography and lack of promoting cover crops in the watershed. << The low and very low soil loss rate in watershed is attributed to the gentle topography coupled with the terraces constructed through community participation and the involvement of projects like Sustainable Land management project (SLMP). https://doi.org/10.1111/j.1440-1770.2011.00489.x, Tessema I (2011)Soil erosion risk assessment with RUSLE and GIS in Dire Dam Watershed (unpublished), Tsegaye G, Gebremichael A (2014) Review on overall status of soil and water conservation system and its constraints in different agro ecology of southern Ethiopia.

Universal Soil Loss Equation (USLE)(Wischmeier and Smith 1965) and Revised Universal Soil Loss Equation(RUSLE) are the common and widely used equations in erosion modeling (Fistikogli and Harmancioglu 2002), However, USLE model has been widely used as it combines the impact of climate, soil, topography and land use on soil loss with limited data (Wischmeier and smith 1978).

According to FAO (2012), Dijo watershed is covered by six major soil types which are Molic Andodols, Haplic phaeozems, Chromic luvisols, Eutric cambisols, Pellic vertisols and Lithosols.

The USLE model does no account Gully erosion in the watershed. Finally, the current finding on erosion was evaluated based on the past 10-year land use land cover scenario. The lowest soil erosion on Molic Andosols could be due to their good aggregate stability and high permeability to water which make these soils resistanttowater erosion. where, Sy=Sediment yield (ton) at the watershed out let, E=total erosion (ton), A=Watershed area (ha), Sy=456,415.60ton/year *(1/123,3950.2), Sy=43,762 tons/year.

Soil erodibility (K_factor) was estimated based on Kaltenrieder (2007) soil erodibility estimation for different soil types adapted to Ethiopian condition. The shallow soil depth coupled with the sandy clay soil texture characteristics of Lithosols leads to low water-holding capacity soil which contributed for comparable soil loss with pellic vertisols.
