Some properties of Guyon's method for drain spacing determination on the marshy gley soil

Abstract

The aim of this work is to show out some properties of Guyon's method for drain spacing determination in unsteady state of flow. The analysis has been carried out in the marshy gley soil of the experimental field with drain spacing of 10 m, 20 m and 30 m. The method assumed modeled dynamics of water recharge, which hasn't been observed during the experimental trial. Therefore, its application is limited.
