Numerical Modelling of the Topographic Wetness Index: An Analysis at Different Scales
Resolution DEM Grid Size Wetness Index
2013/3/7
A variety of landscape properties have been modeled successfully using topographic indices such as topographic wetness index (TWI), defined as ln(a/tanβ), where a is the specific upslope area and β is...
Modelling the dynamic chemical interactions of atmospheric ammonia with leaf surface wetness in a managed grassland canopy
