But the detail — the slow accretion of supporting data and the puzzling incompatibility of some results — is usually ignored. In effect, science stories are ‘edited’ (either by the journalist or by the scientist who ...
متن کاملParameterizing the Spatial Markov Model From Breakthrough Curve Data Alone
The spatial Markov model (SMM) is an upscaled Lagrangian model that effectively captures anomalous transport across a diverse range of hydrologic systems. The distinct feature of the SMM relative to other random walk models is that successive steps are correlated. To date, with some notable exceptions, the model has primarily been applied to data from high-resolution numerical simulations and c...
