Topographic Wetness Index (TWI) is an index or indicator of the effect of local topography on runoff flow direction and accumulation. The index is a function of both the slope and the upstream contributing area.
With support from FEMA and using high resolution DEMs derived from LiDAR, Illinois State Water Survey generated the index for the Illinois counties of DuPage |
