This chapter continues the previous chapter by covering DEM-derived topographic indices. Eight topographic indices are presented, with scope related to flow convergence and the influence of topography on soil moisture or flooding. Special attention is given to the HAND index and its application for flood mapping.

Topographic Indices—Part 2: Flow Convergence, Soil Moisture, and Flooding

  • Adriano Rolim da Paz

摘要

This chapter continues the previous chapter by covering DEM-derived topographic indices. Eight topographic indices are presented, with scope related to flow convergence and the influence of topography on soil moisture or flooding. Special attention is given to the HAND index and its application for flood mapping.
