Meet the top winners of the Water Modeling Hackathon 2026, young innovators who stood out for developing cutting-edge solutions to Rwanda’s water challenges.
The Water Modeling category focused on hydrological modeling of the Nyagisozi sub-catchment and flood hazard assessment downstream using HEC-HMS and HEC-RAS, while the Erosion Control category challenged participants to extract radical terraces from satellite images or orthophotos using R or Python.
The winners walked away with a cash prize of RWF 1,000,000, while runners-up each received RWF 750,000 in recognition of their outstanding performance.
