文摘
- •
We develop a low-cost method to describe river habitats at very large spatial scale.
- •
We use remote sensing and pseudo-2D hydraulic modeling to generate habitat metrics.
- •
These metrics are useful to classify mesohabitat composition and produce reach zonation.
- •
We investigate 3 distinct metrics to capture habitat heterogeneity along the river.
- •
Heterogeneity peak locations are not sensitive to induced error in D–V pixel values.
