KT3D_H2O produced water-level maps are used for particle tracking that can be used to evaluate approximate flow directions and rates, approximate advective(-dispersive) transport and approximate the extent of capture.
Particle tracking uncertainty, associated with the physical process of hydrodynamic dispersion and mixing, is incorporated through a random walk component.
The random walk movements are added to the advective displacements, providing an indication of the expected uncertainty in particle location due to dispersion.
The combined results of the approximate capture zone analyses can be used to evaluate the robustness of hydraulic capture, and identify areas where capture may be compromised by creating the Capture frequency maps.
Capture frequency maps are generated by:
- Processing multiple water level events, each with unique pumping rate data; producing groundwater elevation contours for each event;
- Undertaking particle tracking on each surface and recording the fate of each particle; and,
- Summarizing the results in terms of the fraction of the events for which each particle was removed at an extraction well.
