Subsurface Inflow 25.0 GPM
Root Mat Tensile Strength 14.5 kPa
Subsoil Type
Interaction Mode
Mechanics: Water trapped under shallow turf creates upwards hydrostatic pressure ($P = \rho g h$). If pressure exceeds root anchorage shear strength, the root mat detaches into a squishy waterbed blister.
STATUS: CRITICAL DISTENSION
Click & drag on turf membrane to step or apply localized weight.
