<h1 class='module'>SAGA Wetness Index</h1>
|
|
<div class='author'>(c) 2001 by J.Boehner, O.Conrad</div>
|
|
<div class='description'>The 'SAGA Wetness Index' is, as the name says, similar to the 'Topographic Wetness Index' (TWI), but it is based on a modified catchment area calculation ('Modified Catchment Area'), which does not think of the flow as very thin film. As result it predicts for cells situated in valley floors with a small vertical distance to a channel a more realistic, higher potential soil moisture compared to the standard TWI calculation.<br/>
