Detailed Description

Quoted from: http://www.usask.ca/ip3/download/CRHM_brochure.pdf 

The complete set of CRHM modules can be classified into the following categories:

1. Basin: Basin and hydrologic response unit (HRU) physical, soil, and vegetation characteristics (reference definition for HRU in specifications below)

2. Observation: Interpolates meteorological data to HRU using adiabatic relationships and saturation vapour pressure calculations

3. Snow Transport: Blowing snow transport and sublimation

4. Interception: Rainfall interception, snowfall interception, snow interception in forest canopies and sublimation

5. Radiation: Shortwave direct and diffuse algorithms, slope corrections, snow albedo decay, longwave radiation, canopy transmissivity and net radiation

6. Evaporation: Several physically-based methods for unsaturated and saturated surfaces including transpiration

7. Snowmelt: Energy balance snowmelt, radiation index, temperature index, snow cover depletion and simple land surface scheme melt methods

8. Infiltration: Basic and parametric infiltration routines for frozen soils, frost depth calculation, Green-Ampt infiltration and redistribution for unfrozen soils

9: Soil Moisture Balance: Multiple flowpath 2-layer “bucket” model with sub-surface flow, groundwater, depressional storage and “pond” options

10: Flow: Organic layer flow, timing and storage control of overland flow, mineral interflow, and streamflow, using the lag and route hydrograph and Muskingum routing methods
