Hydraulic Gradient Calculator

Calculate hydraulic gradient i = Δh/L for groundwater and pipe flow. Determine piezometric surface slope, seepage velocity, and critical gradient for piping failure in embankment dams.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.
