An Irrigation Engineering Book Based on the Original Thesis
The HARE Irrigation Project book is based on the original 1995 engineering thesis prepared at the former Arba Minch Water Technology Institute, now Arba Minch University, by Mesfin Hagos, Mitiku Bedru, Seid Shimelis and Tamir Mitiku.
Rooted in the HARE River irrigation study near Arba Minch in southern Ethiopia, the work presents the design of diversion headworks, canal layouts, drop structures, silt-control components, drainage and associated hydraulic infrastructure.
It also addresses water-demand assessment, irrigation requirements, hydrological analysis, canal design, head regulators, cross regulators, weir design and the detailed engineering methodology used by the original team.
The publication is now being developed as more than a reproduction of the historical report. The original calculations remain visible and respected, while separate HARE Revisited sections document how GIS, digital terrain, reconstructed rainfall, HEC-HMS, SWAT and present field evidence change or strengthen the modern engineering understanding of the project.
In this form, the book can serve simultaneously as a historical engineering record, a modern technical case study, and a reference for students and practitioners interested in irrigation and water-resources development.
The modern reassessment is kept distinct from the original 1995 analysis. This allows the book to preserve what the original team calculated while documenting what can now be learned through current data, GIS, hydrological modelling and field evidence.
Event-based rainfall-runoff modelling has been completed for the Hare Weir catchment. The present 50-year HEC-HMS design-event simulation produces an outlet peak discharge of 114.4 m³/s.
DEM-based watershed delineation, HRUs, NASA POWER climate preparation and two successful continuous SWAT simulations have been completed. The analysis now covers water balance, daily streamflow, groundwater contribution, erosion and sediment behaviour.
The present SWAT reference simulation indicates an average upland sediment yield of about 58.4 Mg/ha, together with strong simulated channel deposition. Field observations around the Hare diversion also show significant gravel, sand and finer sediment accumulation.
The 3D model is proportioned around the planned paperback edition. These specifications remain provisional until the interior is completely typeset and the final page count is locked.
The cover intentionally combines the project's engineering identity with the agricultural landscape it was designed to serve: irrigation canals, diversion structures, typical canal sections and headworks drawings.
The front cover establishes the HARE project as a serious irrigation-engineering work. The spine preserves the authors and the 1995 origin. The back cover explains the technical scope and the value of preserving the study for future engineers and readers.
The developing HARE Revisited material adds a second narrative inside the book: the original engineering study remains the historical foundation, while modern GIS, hydrology and model results provide a transparent technical comparison with present understanding.
The publication preserves the collective work of the four original HARE team members while linking the 1995 engineering study to the professional paths and technical experience that followed.
The HARE book page is designed to stand on its own as the permanent project-book home while the technical manuscript continues to develop. When the final edition is published, this section can be connected directly to Amazon KDP or another publisher without redesigning the page.
The planned 430-page extent remains provisional because ongoing HARE Revisited chapters — including hydrology, HEC-HMS, SWAT and sediment assessment — may affect the final manuscript length during typesetting.
