 Runoff Routing Models in ICM InfoWorks Networks

#	🚰 Routing Model	📜 Description	📊 Subcatchment Data Fields Used	🌏 Appropriate For
1	🌊 Clark	Flow is routed using the Clark unit hydrograph method. Lag time and time of concentration are defined by the user.	Time of concentration, Lag time	France and anywhere the Hydrological Engineering Center’s Hydrological Modeling System (HEC-HMS) models are used.
2	🇫🇷 Desbordes	Flow is routed using a single linear reservoir, whose routing coefficient depends on subcatchment area, ground slope and percentage impermeable.	Catchment slope, Catchment dimension (length)	French systems running with event based simulations.
3	⛩️ Kadoya	Flow is routed using the Japanese Quasi Linear Reservoir Method.	Catchment area	Standard runoff model in Japan.
4	🌄 Large Catch	Flow uses two equal linear reservoirs in series.	Catchment slope, Catchment dimension (length)	UK systems where subcatchments are larger than 1 ha.
5	🇯🇵 Non-Linear	Flow is routed using the Japanese Storage Function Method.	Catchment slope, Catchment dimension, and more...	Standard runoff model in Japan.
6	🇬🇧 ReFH	Flow is routed using a kinked triangle unit hydrograph.	Time to peak, Unit hydrograph peak, Degree of kink	UK drainage systems.
7	🏞️ SCS Unit	Flow is routed using an SCS unit hydrograph.	Catchment area, Time to peak, Base Time	Rural areas (except mountainous or flat wetland areas).
8	⛰️ Snyder Unit	Flow is routed using the Snyder unit hydrograph method.	Peaking coefficient, Lag time	Subcatchments in the Appalachian Highlands.
9	🌪️ SWMM	Flow is routed using a single non-linear reservoir.	Catchment slope, Catchment dimension (width)	USA drainage systems using the SWMM runoff model.
10	🕰️ Unit	Flow is routed using a unit hydrograph.	Varies based on calculation method	Varies based on calculation method.
11	🌦️ Wallingford	Flow uses two equal linear reservoirs in series.	Catchment slope	UK systems where sub-catchments are under 1 ha.
12	📐 Rational	Flow is routed using a triangular unit hydrograph.	Varies based on Time of concentration method	Developed for subcatchments in Japan.
13	🇩🇪 Cascade	Flow is routed using a number of linear reservoirs in series.	Storage factor K	Suitable for Germany or similar climates.
14	🌐 RAFTS	Flow is routed using 10 non-linear reservoirs.	Degree urbanization, RAFTS parameters, and more...	Hydrology modeling in various regions.
