03 — Summary

From raw elevation data
to basin-scale intelligence.

The Haro River Basin was delineated into 854 sub-basins using SRTM-derived DEM data, with drainage networks, slope gradients, and aspect maps produced via ArcSWAT. Terrain analysis reveals predominantly gentle-to-moderate slopes punctuated by steep zones, while LULC mapping shows agricultural land (38.4%) and wetlands (21%) as the dominant cover types. Soil mapping is dominated by Silty Clay with significant Sandy Loam patches — directly influencing runoff potential at the sub-basin level. Hydrologic response units integrate slope, soil and land-use into a cohesive modelling framework for downstream water-yield and sediment transport simulations.
