> How does i-Tree Hydro account for infiltration, evapotranspiration, and other components of a water balance?
The technical processes underlying the i-Tree Hydro model are described in the following paper written by original developers of the model. In this paper i-Tree Hydro is referred to by its original name, UFORE-Hydro:

Infiltration rate is a measurement of a dynamic process and therefore it is not a parameter in Step 3 of i-Tree Hydro because it changes over time due to weather and water movement. Infiltration rate is closely related to the saturated hydraulic conductivity (Ksat) near the soil surface, which is a Hydrological Parameter in i-Tree Hydro.
