Exponential (1-seg): T = T₀ exp(−k√A); V = 2T₀/k² — valid when deposit thins by single exponential (Pyle 1989).
Exponential (2-seg): Two piecewise exponentials with break-in-slope; general formula Fierstein & Nathenson (1992) Eq. 18.
Power Law: T = T_pl · (√A)^(−m); V = 2T_pl/(2−m) · [C^(2−m) − B^(2−m)] — Bonadonna & Houghton (2005) Eq. 6.
Weibull: T = θ · exp[−(√A/λ)^n]; V = 2θλ²/n · Γ(2/n) — Bonadonna & Costa (2012). All volumes in DRE-equivalent bulk. R² computed on ln(T) residuals.
