文摘
- •
Hydraulic methods are used to estimate hydraulic conductivity.
- •
Chemical methods are used to estimate leakage rate or porewater velocity.
- •
KZ increases up to three orders of magnitude with horizontal scales of up to 1000 m.
- •
Each tracer used in aquitard porewater has a lower limit of resolution of velocity.
- •
Methods testing only a portion of the aquitard thickness may overestimate KZ.
