Comments.
ClassAyers ("Ayers") for unfrozen soil.
Attempts to infiltrate snowmelt before handling rainfall.
ClassGreenAmpt ("GreenAmpt") for unfrozen soil.
This module immediately combines snowmelt and net_rain before using the GreenAmpt method. It is not recommended.
Classcrack ("crack") and Classfrozen ("frozen") for frozen soil.
These module were developed for the Canadian prairies. During the summer it is assumed that everything infiltrates.
ClassPrairieInfil ("PrairieInfiltration") and ClassAyers ("FrozenAyers") for frozen soil.
These modules can limit summer infiltration using soil texture/groundcover and maximum permissible infitration rates.
ClassGreencrack ("Greencrack") for frozen soil.
GreenAmpt controls summer infiltration and is not recommended.
