THE DETERMINATION OF GROUND WATER LEVELS IN SANDS BY THE SEISMIC REFRACTION METHOD

Theoretical compressional wave velocities are calculated for various systematic packings of uniform spheres with void and water-filled pores. In dry packs, a parabolic increase of velocity with depth is apparent. For both dry and wet packs, an inverse relation exists between porosity and velocity. A comparison is made with field and laboratory results. The feasibility of the refraction method for water table depth determinations is demonstrated. However, to avoid the possibility of depth errors, it is shown that care must be exercised to find the velocity function in the sands above the water table. (A) /TRRL/
