Unit gradient in internal drainage experiments for the determination of soil hydraulic conductivity

Gradiente unitário em experimentos de drenagem interna para determinação da condutividade hidráulica do solo

It is theoretically shown that unit hydraulic potential gradients cannot occur in homogeneous soils undegoing internal drainage process even though this assumption has been used successfully by several authors of soil hydraulic conductivity methods.
