Description	TETRA is a simple interactive utility to calculate velocity components in 3D from hydraulic head data. Groups of four observation points are connected to form tetrahedrons, and a linear interpolation is used to calculate head gradients for each tetrahedron. Application of Darcy's Law then yields velocity components. The program supports confined/unconfined anisotropic, homogeneous aquifers. Menu-driven,
