Key Concepts (a subjective and not-exhaustive list) Groundwater ----- Flow Nets: how to draw, characteristics of a properly drawn flow net (Qb,, same for all streamtubes, larger squares indicate slower flow and decreased dh/dx), calculating discharge Well Equations: Steady-state ("Theim equation"): ds/dr and s(r) depend on Qw and aquifer characteristics Transient ("Theis equation"): depends on Qw, aquifer characteristics, and S (S = how much water you get for a given change in head; sponge analogy might help) Transport Models: 1) Pulse injection: same as in surface water, except accounting for porosity, and D = av (different flow paths leads to spreading in direction of travel) 2) Continuous input: mostly conceptual Equivalent to figure 3-17: "edges mixed", rather than Gaussian spreading CL1,-tC o ert& (i-qt to A, t2. X Retardation: combined effects of transport and chemistry; for sorption to organic carbon, look up Kow and use empirical equation to get Ko, which leads to Kd and R. Note that retardation affects
