In this research, a geotechnical and management investigations were conducted to evaluate and repair a slope failure occurred along the right side of the spillway related to Kufranjeh Dam located at Wadi Kufranjeh–Jordan. The geotechnical investigation included engineering evaluations for the geological formations and structures existing at Kufranjeh Dam region, in addition to the evaluations for the existing slope failure area. Furthermore, the first phase of investigation included suggesting several proposed alternatives (solutions) to be performed in order to repair the failure zone and improve the performance for the current geological formations. Out of these suggestions, three alternatives were selected as the most appropriate and applicable for the study area; however, these selections are gabion wall, reinforced concrete counterfort wall, and reinforced earth retaining wall. Detailed design and shop drawings (for each of these selected alternatives) was implemented and presented for the purpose of entering into the second phase of investigation regarding this research. The second phase of investigation was concerning the management part of this research, in which the most suitable and applicable alternative was chosen depending on engineering comparisons between alternatives that considered the same engineering performance for them, the final cost of executing each project, the total construction duration for each, in addition to the develop work plan for the project. However, the findings for this research showed that the reinforced earth retaining wall is the most suitable and applicable alternative compared with other proposed alternatives.
