Summary of the Article "2.7. Hydrology — ctsm CTSM master documentation":

Hydrology in the Community Land Model (CLM)

1. Hydrological Processes Represented
   - The model parameterizes various hydrological processes, including:
     - Interception, throughfall, canopy drip
     - Snow accumulation and melt, water transfer between snow layers
     - Infiltration, evaporation, surface runoff, sub-surface drainage
     - Redistribution within the soil column
     - Groundwater discharge and recharge

2. Water Balance Equation
   - The total water balance of the system is described by the equation:
     ΔW_can,liq + ΔW_can,sno + ΔW_sfc + ΔW_sno + Σ(Δw_liq,i + Δw_ice,i) + ΔW_a = (q_rain + q_sno - E_v - E_g - q_over - q_h2osfc - q_drai - q_rgwl - q_snwcp,ice) Δt
   - Where the terms represent changes in various water storages and fluxes, such as canopy liquid water, canopy snow, surface water, snow, soil liquid water, soil ice, and unconfined aquifer.

3. Hydrological Processes Diagram
   - The article includes a figure (Figure 2.7.1) that illustrates the hydrological processes represented in the CLM.
