Simulation Depth : Depth at which soil temperature and water are predicted. Layer 1 = 0.0; All other layers > 0
Initial Temperature : Soil temperature at beginning of simulation. (Input not required if soil temperature supplied from user file in "Lower Boundary Condition for Water Flow)
Initial Water Content : Soil water content at beginning of simulation. (Input not required if soil water content supplied from user file specified in "Lower Boundary Condition for Heat Flow")
