PARTIAL ANALYSIS APPLIED TO SCALE PROBLEMS IN SURFACE MOISTURE FLUXES

Partial analysis is applied to the problem of predicting the moisture fluxes of infiltration and evaporation at land surfaces. The discussion covers the widely different scales of the soil particle, a soil pedon, a field, a basin and a biome. It is suggested that simplified models can be used at these different scales to provide bounding solutions to the integrated behaviour of land surface fluxes of interest in linking hydrologic models and general circulation climate models.
