Project Description
Groundwater Vistas 7 model for a laboratory channel system with dimensions 3.0 m (length), 0.8 m (width), and approximately 0.30 m water depth.
Use a student-version-compatible finite-difference grid (around 40 columns) and one model layer unless you judge vertical discretization is necessary.
Base hydraulic parameters are porosity \(n = 0.5\) and hydraulic conductivity \(K = 8000\)–\(12000\) cm/day (80–120 m/day).
A deuterium oxide (D2O, heavy water) tracer test was performed, with a total water addition of about 40 L during a short single injection event (about 3 hours).
Reported tracer preparation was 0.5 mL D2O added per 16 L of 3 bucket of water, and this dosing should be reflected in the transport setup at an appropriate concentration scale.
The outlet boundary in the physical system corresponds to a 30 cm head condition and should be represented with the most physically consistent boundary implementation.
A small internal wall/barrier exists near the injection side and must be included as a flow barrier feature because it affects flow and particle pathways.
Run and compare flow simulation, tracer transport simulation, and MODPATH particle tracking for at least two scenarios (without barrier and with barrier).
Final deliverables should include clear maps/plots of head, velocity/flow direction, tracer plume evolution, particle pathlines/travel behavior, and 1–2 optimization scenarios to improve overall flow behavior.
