Ethiopian Irrigation and Hydraulic Engineer with more than eight years of professional experience in irrigation development, hydraulic design, construction supervision and contract administration. He holds a BSc in Soil and Water Engineering from Haramaya University and has worked on small-scale, spate and large-scale irrigation projects through the Oromia Water Works Design and Supervision Enterprise and the Engineering Corporation of Oromia. His professional assignments include construction supervision and contract administration at the Bareda Lencha and Mechitu irrigation projects, site engineering at Walanchiti Bofa, senior irrigation design work for the Rammis Large-Scale Irrigation Project, hydraulic engineering for the Fentale Irrigation Development Project, and irrigation design for the ongoing Hiddi Dam Large-Scale Irrigation Project. His practical expertise covers canal and headworks design, hydraulic analysis, cross-drainage structures, surface-irrigation design, construction planning, contract management, payment certification, engineering drawings, quantity estimation and project reporting. He also works with engineering and geospatial software including AutoCAD Civil 3D, ArcGIS, SAP2000, GeoStudio, WaterCAD, Global Mapper, Eagle Point and Primavera P6.

Key Expertise

Major Projects and Contributions

• Bareda Lencha Small-Scale Irrigation Project
  Worked as an irrigation and site engineer in construction supervision and contract administration. Responsibilities included excavation and alignment of the main canal, headworks and cross-drainage structures; canal route and access-road layout; engineering surveys; quantity take-off; construction progress reporting; stakeholder coordination; and supervision of works to achieve the required gradient, flow, quality and project specifications.
• Mechitu Spate Irrigation Project
  Served as Irrigation Engineer and Site Engineer for construction supervision and contract administration. Responsibilities included supervision of project implementation, hydraulic review of the irrigation network, preparation of working drawings and work orders, variation and omission works, quantity measurement, construction scheduling, progress reporting, payment certification and design review of irrigation structures.
• Walanchiti Bofa Irrigation Project
  Worked as Site and Irrigation Engineer supervising canal-related construction, access and haul roads, earthworks, flumes, culverts, drainage structures and other main-canal infrastructure. Duties included hydraulic network review, compliance with drawings and specifications, preparation of working drawings, quantity measurement, progress reporting, payment certification and supervision of construction quality, time and cost requirements.
• Rammis Large-Scale Irrigation Project
  Worked as Senior Irrigation Engineer on irrigation-system design. Responsibilities included assessment of crops and crop-water requirements, field topography, soils and drainage conditions; selection of suitable surface-irrigation methods; calculation of flow rates, velocities and channel cross sections; preparation of detailed engineering drawings; and technical design review with project stakeholders.
• Fentale Irrigation Development Project
  Worked as Hydraulic Engineer on irrigation rehabilitation and development activities. Responsibilities included supervision of Fentale headworks repair, major-canal silt removal, rehabilitation of approximately 34 km of dry access road, construction of approximately 25 km of access road along the branch canal, hydraulic network review, supervision of canal and drainage structures, working drawings, progress reporting, variation works and payment certification.
• Hiddi Dam Large-Scale Irrigation Project
  Currently works as an Irrigation Engineer on the design of the Hiddi Dam Large-Scale Irrigation Project. Responsibilities include defining irrigation-system objectives, assessing crops and water requirements, evaluating field size, topography and soils, reviewing drainage and existing infrastructure, selecting appropriate surface-irrigation methods, considering infiltration and application uniformity, calculating flows and channel dimensions, and preparing detailed engineering drawings and specifications.
• Irrigation Engineering Software and Professional Training
  Completed professional training in construction contract management and alternative dispute resolution, GeoStudio for dam-design applications, diversion-weir and canal layout and design using AutoCAD Civil 3D, ArcGIS 10.8.1 and SAP2000, and Primavera P6. He also reports working knowledge of WaterCAD, Global Mapper, Eagle Point, MS Office and other engineering tools used in irrigation projects.
