Engineering (general)
To evaluate the potential for internal erosion or piping at the Dam, hand calculations will be performed using flownets from the existing seepage analysis.
Seepage gradients, or the change in head over the change in distance, will be evaluated using these existing flownets.
The estimated gradient will be compared to maximum recommended values to evaluate the potential for piping. A maximum gradient of 0.2 to 0.4 is typically recommended for dams, and a gradient of 1.0 or greater indicates piping is likely to occur.

Discussion
De tels gradient doivent tenir compte de la densité traversée, de la hauteur, des débits etc ...
Je dirais donc pour cette phrase que le gradient de fuite (seepage gardient) est fonction du "gradient de pression"
