Project Location & Catchment
Boundary reconstruction pending
The future base map will establish the HARE project location, catchment boundary, river network, command area and principal engineering reference points.

HARE Revisited
Terrain · Catchment · Land · Hydrology · Irrigation
This section is being prepared as the geospatial workspace for the modern reassessment of HARE. It will progressively bring together the catchment boundary, DEM, elevation, slope, drainage, land use, soils, rainfall, command area, canals, headworks and other spatial products needed to compare the original engineering study with present-day analysis.

Current status
A Finished Framework Waiting for the Real Analysis
The page is intentionally being completed before the final GIS calculations. This allows the HARE spatial archive to have a permanent structure now while ensuring that no unverified area, elevation, slope, land-cover percentage, catchment statistic or infrastructure coordinate is presented as fact.
Spatial layers
The HARE Geospatial Analysis Set
Each layer below has a defined place in the future HARE reassessment. The page can therefore be populated progressively: once a map or calculation is completed, its current placeholder can be replaced by the verified map, statistics, methodology and downloadable technical outputs.
02
Digital Elevation Model
DEM processing pending
A modern DEM will provide the elevation surface used for terrain interpretation, watershed delineation, slope analysis and drainage extraction.
03
Elevation & Hillshade
Analysis pending
Elevation classes and hillshade will be prepared to visualize terrain form, relief, valley geometry and the physical setting of the irrigation system.
04
Slope Analysis
Analysis pending
Slope classes will be calculated from the DEM and interpreted in relation to runoff, erosion, canal alignment, irrigation suitability and terrain constraints.
05
Drainage Network
Extraction pending
Flow direction and flow accumulation will be used to extract drainage paths and compare modern terrain-derived drainage with the original engineering understanding.
06
Land Use / Land Cover
Classification pending
Current land-cover information will be compiled and summarized for the HARE catchment and irrigation area, with areas and percentages reported only after analysis.
07
Soils & Land Suitability
Spatial review pending
Available soil information will be integrated with terrain and irrigation criteria to support a modern review of land suitability and agricultural potential.
08
Rainfall & Hydroclimate
Dataset selection pending
Modern rainfall and climate datasets will be compared with the historical study period and prepared for hydrological and irrigation-demand reassessment.
09
Command Area & Irrigation Layout
Digitisation pending
The command area, canal alignments, headworks and related irrigation infrastructure will be digitised or reconstructed where reliable source information is available.
10
Hydrological Reassessment
Future analysis
Catchment characteristics, rainfall, flow pathways and hydrological calculations will be recomputed and compared transparently with the original 1995 design study.
HARE spatial workflow
From Source Data to Engineering Interpretation
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.
01
Source Data
Select suitable DEM, satellite, rainfall, land-cover, soil and historical project information.
02
DEM Preparation
Clip, condition and inspect the elevation model before deriving terrain products.
03
Catchment Delineation
Derive flow direction, flow accumulation, drainage network and watershed boundary.
04
Terrain Analysis
Calculate elevation, slope, hillshade and terrain summaries.
05
Land & Irrigation
Assess land cover, soils, command area, canal alignment and irrigation suitability.
06
Hydrology
Revisit rainfall, runoff, dry-flow and flood analyses with modern data and reproducible methods.
07
1995 Comparison
Compare modern results with the original HARE calculations, assumptions, maps and design decisions.
HARE Revisited
1995 Engineering Understanding → Modern Spatial Evidence
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.
Original HARE study · 1995
Historical Engineering Evidence
- Original project maps and drawings
- Field and site information available to the team
- Historical rainfall and river-flow records
- Manual and tabulated calculations

- Engineering interpretation based on the tools available at the time
Modern reassessment · forthcoming
Digital Terrain & Geospatial Evidence

- Digitally delineated watershed and drainage network
- Satellite-based land-use / land-cover information
- GIS-based slope, elevation and land analysis
- Modern rainfall and hydroclimatic datasets
- Reproducible hydrological and spatial calculations

Publication principles
Measured First, Published Second
No invented spatial statistics
Catchment area, slope classes, land-use percentages, elevations and coordinates will appear only after calculation and verification.
Historical and modern evidence remain distinct
Original 1995 information will be clearly separated from new GIS-derived results so that the archive remains technically transparent.
Methods will accompany results
Where practical, each map will record its source dataset, processing method, date, spatial resolution and interpretation.
Continue through the HARE Digital Archive
The spatial analysis will connect directly with the preserved project history and the developing HARE engineering book.
