| {{htmlJSON.Abstract}} | This function is used to calculate the Topographic Wetness Index (TWI) defined as the ratio of the natural log of the specific catchment area (contributing area) to slope, ln(a/S), or ln(a/tan (beta)). This provides an indication of depth to water table. No data values occur in locations where slope is 0 (flat) | |
