AQTESOLV Linear & Bilinear Flow Plots

AQTESOLV Linear & Bilinear Flow Plots are useful diagnostic tools for identifying linear flow behavior in single fractures and channel aquifers. The linear flow plot transforms the time scale by its square root.

  • On a log-log linear flow plot, early-time data exhibiting a unit slope are indicative of linear flow conditions to a single fracture with infinite conductivity or uniform flux along the fracture.
  • On a log-log linear flow plot, late-time data exhibiting a unit slope are indicative of linear flow in a channel aquifer (see Figure to right).

Aqtesolv Linear Flow Plots

Bilinear flow plots are useful diagnostic tools for identifying fracture flow behavior, flow in dikes or flow in a channel aquifer with permeable walls.

  • On a log-log bilinear flow plot, early-time data on exhibiting a unit slope are indicative of bilinear flow to a single fracture with finite conductivity.
  • On a log-log bilinear flow plot, late-time data exhibiting a unit slope are indicative of bilinear flow in a permeable dike surrounded by less permeable country rock or linear flow in a channel aquifer with permeable walls.
