According to Palmeira et al. (2005), the definition of GR based on water head measurements closer to the geotextile filter interface is recommended to predict the soil—geotextile interaction mechanisms more accurately. 

In all hydraulic applications, the base soil—geotextile interaction is a complex process and many factors related to the base soil, the geotextile filter, and the boundary conditions are involved (Table 8.2).

Soil—geotextile interaction in pull-out mode The geotextile length for slope and wall reinforcement is designed to provide anchorage beyond the potential failure surface. Such resistance can be modeled in the laboratory using a puU-out test. The pull-out resistance of the geotextile obtained in the test can be expressed as (Eq. [15.6]) ...

In those events that a combined failure of soil and structural elements can be expected, due consideration must be given to the soil-structure interaction in terms of their relative stiffness. These cases include, for instance, failure surfaces intersecting structural members such as piles, flexible walls or armouring (e.g. geotextiles). Such an approach is, however, not always feasible in Limit Equilibrium Methods. The Finite Element Method is a more appropriate tool for the analysis of soil-structure interaction.

There are three mechanisms by which the interaction between the soil and the reinforcing geotextile can resist induced tensile loads ...
