Suitability explorer
Compare MALF and median flow with their paired wetted widths. Adjust clarity, optical penetration and depth distributions, or inspect individual reach slopes and roughness.
Open suitability mapBathylidar survey screening
Explore modelled bed coverage and the seasonal evidence for clearer water across New Zealand rivers of stream order 3 and above.
Seasonal evidence
Inspect monitoring-site clarity and monthly sampling, then explore preliminary national estimates of the preferred survey season.
Open seasonal mapProvisional research screening. Estimates depend on model assumptions and data quality. Regional seasonal transfer failed one or more validation gates and remains exploratory. Bed coverage estimates are not probabilities of successful lidar retrieval.
