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.<br>É mostrado teoricamente que gradientes un...

Description
Summary: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.<br>É mostrado teoricamente que gradientes unitários de potencial hidráulico da água não podem ocorrer em perfis homogêneos de solo sob drenagem interna, apesar desta aproximação ter sido utilizada com sucesso em vários métodos de determinação de condutividade hidráulica do solo.
