On the calculation of the topographic wetness index: evaluation of different methods based on field observations
The topographic wetness index (TWI, ln(<i>a</i>/tan<I>β</I>)), which combines local upslope contributing area and slope, is commonly used to quantify topographic control on hydrological processes. Methods of computing this index differ primarily in the way the upslop...
