This section is the geospatial and engineering-visualization workspace for the modern reassessment of HARE. The spatial archive includes watershed-scale land use / land cover, drainage, relief, contours, slope and rainfall products together with dedicated command-area maps. The 2026 command-area canal-system map now places Primary Canal 1, Primary Canal 2, Secondary Canal 1 and the Hare River directly on current satellite imagery. Newly published PC1 and PC2 longitudinal-profile figures document the designed canal-bed profiles and drop structures, while reconstructed upstream views document the HARE weir, intake and headworks. A separate rainfall-analysis viewer presents the monthly rainfall figures and key watershed statistics without crowding the page.
The HARE spatial products and rainfall-analysis figures are presented as separate full-size figures rather than stacking several large maps on one page. Select a product below and the viewer will display only that figure at large size. This keeps the archive clean, fast and easy to extend while preserving every map as an independent technical output.
Integrated HARE watershed presentation showing land use / land cover over terrain relief, the drainage network, watershed boundary, Hare Weir outlet and Hare River mouth.
Contour presentation for the Hare Watershed, prepared as part of the modern terrain reassessment of the HARE Irrigation Project.
Slope classification of the Hare Watershed for terrain interpretation and the modern reassessment of runoff, erosion, irrigation suitability and engineering constraints.
Annual rainfall distribution across the Hare Watershed for 1990, derived from precipitation data and summarized over the watershed for the HARE Revisited hydrological reassessment.
Geographic location of the Hare Irrigation Project within Ethiopia, showing the project region, surrounding project-area woredas and the Hare watershed in an enlarged locator view.
Soil map of the Hare project area showing mapped units 257 and 310. Both are loam soils with only small differences in clay, silt and sand content. The saturation and drainage comparison shown on the figure is a qualitative texture-based interpretation rather than a measured field saturation result.
Slope distribution prepared for the earlier reconstructed command-area delineation. The current 2026 gross command-area boundary has since been expanded and is documented in the updated land-use and canal-system products. The slope map remains useful for terrain interpretation and canal-alignment review pending regeneration against the final boundary.
Land-use and land-cover distribution within the reconstructed HARE command area, presented over terrain relief to show the spatial relationship between crops, trees, built areas, rangeland, water features, drainage and topography.
Current satellite-background presentation of the HARE command area and principal conveyance network. The map identifies Primary Canal 1 (9.307 km), Primary Canal 2 (5.902 km), Secondary Canal 1 along the ridge (6.129 km), the Hare River, Hare Weir outlet and Hare River mouth. The 2026 GIS reassessment distinguishes the gross command-area boundary from approximately 2,601.40 ha of irrigable land represented by trees and crops.
Monthly rainfall comparison for the Hare Irrigation Project over the 1981–1990 analysis period, showing seasonal and interannual rainfall variability used in the HARE Revisited hydrological reassessment.
Derived 1-in-5 dry-year rainfall for the 1981–1990 period, prepared to support dependable-rainfall interpretation and irrigation-water planning for HARE Revisited.
Reconstructed longitudinal profile of Primary Canal 1 (PC1), showing the natural ground profile, designed canal-bed profile and identified vertical drop structures along the approximately 9.13 km alignment. The figure records the profile-control locations and bed-elevation changes developed during the 2026 hydraulic reassessment.
Reconstructed longitudinal profile of Primary Canal 2 (PC2), showing the natural ground profile, designed canal-bed profile and identified vertical drop structures along the approximately 6.10 km alignment. The figure documents the grade-control requirements identified from the measured terrain profile during the 2026 hydraulic reassessment.
These engineering visualizations reconstruct the upstream arrangement of the HARE diversion works from the available field photographs, video evidence and surviving structural details. They are presented separately from the GIS map library because they document the physical hydraulic structures rather than spatial-analysis products.
Reconstructed upstream view of the intake arrangement. The main opening conveys diverted water into the irrigation canal, while the adjacent gate provides a controlled return path toward the river when excess water reaches the intake area.
Reconstructed upstream view of the diversion weir and left-bank headworks. The intake structure is shown on the left, with the intake-gate operating wheel directly above its gate and the sluice-gate operating mechanism positioned above the sluice opening behind it.
The 1990 annual rainfall map in the main GIS library is supported by three separate analytical figures. Select a figure below to view the monthly rainfall bar chart, the seasonal rainfall line graph or the consolidated key watershed statistics. Only one large figure is displayed at a time, preserving a clean page while keeping each image fully readable.
Monthly mean rainfall over the Hare Watershed in 1990. The twelve monthly values sum to a total annual rainfall of 1,074.11 mm.
Seasonal rainfall pattern of the Hare Watershed in 1990, showing the monthly progression of rainfall and the principal wet and dry periods.
Selected GIS-derived watershed characteristics compiled for HARE Revisited, including catchment areas, elevations, estimated crop area, analysed crop/command-area slope and total annual rainfall for 1990.
The HARE spatial archive now separates its major cartographic, hydrological and engineering products so each can be examined clearly at full size. The main library contains thirteen published products, including watershed and command-area maps, the command-area canal-system map, rainfall-design figures and the PC1/PC2 longitudinal-profile drawings, while the dedicated rainfall viewer presents the monthly bar chart, seasonal line graph and key watershed statistics.
Each layer below has a defined place in the HARE reassessment. Several products are already published as separate figures in the map library, while the remaining layers will be added progressively with verified maps, statistics, methodology and technical outputs.
A dedicated HARE Irrigation Project location map is now published in the main map library, while the integrated watershed map continues to present the watershed boundary, drainage network, Hare Weir outlet and Hare River mouth. Additional command-area detail can be added as the archive develops.
A modern DEM will provide the elevation surface used for terrain interpretation, watershed delineation, slope analysis and drainage extraction.
Hillshade relief is integrated into the watershed presentation map, and a dedicated contour map is now included in the published map library to document terrain form and elevation structure.
Slope analysis is now published at both watershed and command-area scales. The command-area map supports irrigation-suitability assessment and canal-alignment review by distinguishing gentle, moderate and steeper terrain within the reconstructed irrigable area.
A modern drainage network is now presented in the first integrated HARE watershed map. Flow-direction and flow-accumulation products will be documented separately as the technical analysis continues.
Land use / land cover is now presented at both watershed and command-area scales. The command-area figure documents the 2026 mapped classes, while the new satellite-background canal-system map shows how the primary and secondary canals relate spatially to the Hare River, settlements, cultivated land and the updated project boundary.
A dedicated soil map is now published for the Hare project area, documenting the two mapped loam-soil units and their slight textural differences. Terrain and irrigation criteria can be integrated progressively for the broader land-suitability review.
The archive now includes the 1990 annual rainfall distribution map, a monthly rainfall bar chart, a seasonal rainfall line graph and a consolidated watershed statistics figure. Further years and hydroclimatic comparisons can be added progressively.
The updated 2026 GIS reassessment delineates a gross HARE command area of approximately 3,384.06 ha. The 10 m land-use raster represents approximately 3,399.69 ha because of raster-cell boundary effects, of which approximately 2,601.40 ha (trees + crops) is treated as preliminary irrigable land. The published canal-system map shows Primary Canal 1 (9.307 km), Primary Canal 2 (5.902 km), Secondary Canal 1 along the ridge (6.129 km), the Hare River, Hare Weir outlet and Hare River mouth on current satellite imagery. The PC1 and PC2 longitudinal-profile figures are now also published, documenting the reconstructed canal-bed profiles and identified drop-structure locations. Detailed hydraulic structures, turnouts, division boxes and chute design remain under development.
Catchment characteristics, rainfall, flow pathways and hydrological calculations will be recomputed and compared transparently with the original 1995 design study.
The modern reassessment will follow a transparent sequence so that each derived map and statistic can be traced back to its source data and processing method.
The modern work is not intended to overwrite the original HARE study. Its purpose is to place the original engineering decisions beside contemporary terrain, satellite, hydrological and GIS evidence so that both the strengths and the limitations of the earlier analysis can be understood clearly.
The first integrated watershed map is now part of the archive. As the technical work continues, this portal will expand into a documented geospatial record of the HARE catchment and irrigation system.
The spatial analysis will connect directly with the preserved project history and the developing HARE engineering book.
