In Arujya and Bilbo watershed, soil erosion is one of the series causes of soil degradation. The aim of this study was to technical evaluation of physical SWC measures constructed during the 2007 E.C campaign on cultivated field and implementation approaches in SWC development campaign and to analyze land use and land cover change. The data were collected through field measurements and satellite image download from NASA website. The selected physical soil and water conservation measures in both watersheds were level soil bund and level fanyajuu. For fanyajuu technical evaluation of the structures showed that generally in Bilbo watershed ditch depth, ditch width and spacing at 10-15% slope class and in Arujya watersheds ditch width and bottom width of embankment were lower than the recommended one and spacing at 15-30% slope higher than recommended. For soil bund, the technical evaluation ditch depth was in both watershed and ditch width in Bilbo was smaller than recommended and spacing in both watersheds wider than recommended value. In Bilbo watershed, forest coverage increased by 11.22% from 1987 to 2010. Grass land coverage decreased by 4.76% between 1987 and 2010 and then increased from 2010 to 2015. In Arujya watershed forest coverage was decreased by 0.46% from 1987 to 2010. Shrub and bush land cover decreased by 0.41% between 1987 and 2010. Cultivated land increased by 3.4% between 2010 and 2015. Similarly, forest land decreased by 0.13% in 2010. In the same period, the rate of shrubs and bushes decreased by 2.58% from 2015 to 2010. Technical evaluation needs some improvement in the design, community participation in planning phase and land cover changes shows affected cultivated land and vegetation cover through the population increment. It recommended that the future development activities will be used these technologies more for better management of the natural resources in watershed.
