Where rain becomes flow.
An interactive terrain and rainfall-to-runoff model for the Douglas basin, remixed from public elevation, climate, and hydrography sources — plus a recommended community rain-gauge network to replace the placeholders with measured ground truth.

Raw catalog, prototype zone geometry, and the recommended field-network plan: source-catalog.json · microclimate-zones.geojson · field-network-plan.json
Status: prototype data. The microclimate cells and modeled flow paths above are analytical placeholders for interface development — not measured, DEM-derived, or engineering-grade flood boundaries. Do not use them for flood forecasting.
