A new riparian wetland module (SWATrw) is developed for SWAT.
SWATrw provides improved simulation of wetland, river and aquifer interactions.
SWAT and SWATrw are compared for the Barak-Kushiyara Basin (India/Bangladesh).
Hydrological dynamics of the basin's wetlands are more closely simulated by SWATrw.
SWATrw simulates flash floods and dry season wetland persistence. SWAT does not.
