1. Groundwater Modeling Conversion to Transient Particle Tracking

2. Transient Simulation Time dependent variables – Recharge (e.g. winter vs. summer) – Abstraction (daily or monthly schedule) – Observation ( time series of water level or concentration) Calibration ( comparing the time series..) Used for prediction Solution considers ∆S/ ∆t ≠ 0

4. # of time steps

5. Particle Tracking Used for tracking contaminates/particle or tracers from sources to destination at different time steps. Examine the effectiveness of recovery schemes in their ability to capture all the contaminants Examine the extent where the contaminants can travel Calculate the travel time and distance
