SWAP version 4 - Theory description and user manual

“SWAP (Soil-Water-Atmosphere-Plant) simulates transport of water, solutes and heat in the vadose zone in interaction with vegetation development. In the vertical direction the model domain reaches from a plane just above the canopy to a plane in the shallow groundwater. In this zone the transport processes are predominantly vertical, therefore SWAP is a one-dimensional, vertically directed model. In the horizontal direction, SWAP’s main focus is the field scale.”
